The first terminal shares a sharing link generated by the screen sharing application program to the second terminal, so that the second terminal can acquire the network address of the first terminal after accessing the sharing link, connection is established with the first terminal according to the network address, and the first terminal synchronizes screen information to the second terminal according to the established connection; the technical effect that the second terminal can share the screen information of the first terminal under the condition that screen sharing application program does not need to be installed and complex data operation does not need to be carried out is achieved.

Optionally, the generating a sharing link includes: acquiring a user account logged in the screen sharing application program; when the user account is not provided with the sharing password, generating a sharing link for the user account by using a timestamp; and when the user account is provided with a shared password, generating a shared link for the user account by using a timestamp and the shared password.

The sharing link is generated through the user account and the timestamp, so that the sharing link has uniqueness, and the second terminal can be guaranteed to accurately acquire the network address of the first terminal according to the sharing link; on the basis, the sharing link can be set by using the sharing password, so that the second terminal can share the screen information of the first terminal only by verifying the sharing password when accessing the sharing link, thereby avoiding other terminals without the sharing password from sharing the screen information of the first terminal, and improving the security of screen sharing.

Optionally, the method further includes: sending the generated sharing link to a server corresponding to the screen sharing application program; when the sharing link corresponds to a user account, the sharing link is used for triggering the server to store the sharing link, the user account and the network address of the first terminal as a group of corresponding relations; when the sharing link corresponds to a user account and a sharing password, the sharing link is used for triggering the server to store the sharing link, the user account, the sharing password and the network address of the first terminal as a group of corresponding relations.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic diagram illustrating an implementation environment related to a screen information sharing method according to some exemplary embodiments, and as shown in fig. 1, the implementation environment may include a first terminal 110, a second terminal 120, and a server 130.

The first terminal 110 and the second terminal 120 may be a smart phone, a tablet computer, a smart tv, an e-book reader, a multimedia playing device, a laptop portable computer, a desktop computer, and the like.

It should be noted that the first terminal 110 and the second terminal 120 may be the same type of device or different types of devices, and are not limited herein. Wherein the first terminal 110 is installed with a screen sharing application.

The server 130 may be a single server, or may be a server cluster composed of a plurality of servers, and is not limited herein.

In addition, any two of the first terminal 110, the second terminal 120 and the server 130 may be connected through a wired network or a wireless network.

Fig. 2 is a flowchart illustrating a screen information sharing method according to an exemplary embodiment, which is applied to the first terminal 110 in the implementation environment illustrated in fig. 1, as illustrated in fig. 2, and includes the following steps.

In step 201, when the screen sharing application receives a screen sharing instruction, a sharing link is generated, and after the sharing link is shared to the second terminal, the second terminal is triggered to open the sharing link by using the browser, a network address of the first terminal is obtained, and a connection is established with the first terminal according to the network address.

The first terminal firstly receives a screen sharing instruction from a user before sharing screen information, and generates a corresponding sharing link after receiving the screen sharing instruction by using a screen sharing application program.

Optionally, the screen sharing instruction may be generated when a user inputs text for instructing screen sharing, may also be generated when the user clicks a screen sharing control, and may also be generated when the user slides according to a predetermined sliding gesture, which is not limited herein.

In a specific implementation, the first terminal may encapsulate the shared link in a packet body of the packet, and send the packet by using the network address of the first terminal as a source address. Correspondingly, the device receiving the message may analyze a message header of the message, and determine a source address in the message header as the network address of the first terminal.

Optionally, the sharing mode that the first terminal shares the sharing link with the second terminal includes at least one of: the first terminal encapsulates the shared link in a message body of the message through a social application program and sends the message body to the second terminal; the first terminal intercepts the generated sharing link through screen capture and sends the sharing link to the second terminal; the second terminal shoots or scans the sharing link displayed on the first terminal by using the camera to acquire the sharing link.

In one possible approach, the user of the second terminal is asked to read the shared link from the first terminal and input it to the second terminal.

After the second terminal is notified of the sharing link, the sharing link may be accessed by inputting the sharing link in the browser.

Generally, a terminal in the existing market or a browser supported in the related art can support a web real-time communication (WebRTC) technology, which can achieve the effect of real-time communication based on a web page.

After the second terminal acquires the network address of the first terminal, the second terminal can establish connection with the first terminal through a WebRTC technology.

In step 202, after the connection is established with the second terminal, the screen information displayed on the screen of the first terminal is sent to the second terminal in real time through the connection, and the screen information is used for triggering the second terminal to synchronously display the screen information on the screen.

After the second terminal accesses the sharing link sent by the first terminal through the browser and establishes connection with the first terminal based on the WebRTC technology, the first terminal sends and synchronizes screen information of the first terminal to the second terminal according to the established connection, and the purpose that the first terminal shares the screen information of the first terminal to the second terminal is achieved.

In summary, in the screen information sharing method provided in the embodiment of the present disclosure, the first terminal shares the sharing link generated by the screen sharing application to the second terminal, so that the second terminal can obtain the network address of the first terminal after accessing the sharing link, so as to establish a connection with the first terminal according to the network address, and the first terminal synchronizes the screen information to the second terminal according to the established connection; the technical effect that the second terminal can share the screen information of the first terminal under the condition that screen sharing application program does not need to be installed and complex data operation does not need to be carried out is achieved.

Fig. 3 is a flowchart illustrating a screen information sharing method according to another exemplary embodiment, which is applied to the server 130 in the implementation environment illustrated in fig. 1, as illustrated in fig. 3, and includes the following steps.

In step 301, a network address obtaining request sent by the second terminal is received, where the network address obtaining request is generated after the second terminal opens a sharing link by using a browser, and the sharing link is generated after the screen sharing application in the first terminal receives a screen sharing instruction.

When the first terminal shares the screen information of the first terminal with the second terminal, the network address of the second terminal can be received through the transfer of the server corresponding to the screen sharing application program, and the network address of the first terminal is shared to the second terminal.

In step 302, the stored network address corresponding to the shared link is queried.

In actual implementation, before sharing the shared link generated by the screen sharing application program for the second terminal, the first terminal may encapsulate the shared link in a message body, and send the message encapsulated with the shared link to the server with the network address of the first terminal as the source address of the message. After receiving the message, the server may analyze the shared link, the user account in the shared link, and the network address of the first terminal, and correspondingly store the user account, the analyzed shared link in the message body, and the analyzed network address.

Therefore, when the server receives a network address acquisition request sent by the second terminal and determines that the second terminal requests to acquire a network address corresponding to a certain shared link, the server queries the stored network address corresponding to the shared link.

In step 303, a network address corresponding to the sharing link is sent to the second terminal, where the network address is used to trigger the second terminal to establish a connection with the first terminal having the network address, so as to receive and synchronously display screen information of the first terminal sent by the first terminal in real time.

After the server finds the corresponding network address according to the network address acquisition request of the second terminal, the server can send the network address to the second terminal.

After the second terminal establishes connection with the first terminal through the acquired network address of the first terminal and based on the WebRTC technology, the first terminal sends and synchronizes screen information of the first terminal to the second terminal according to the established connection, and the purpose that the first terminal shares the screen information of the first terminal to the second terminal is achieved.

In summary, in the screen information sharing method provided in the embodiment of the present disclosure, after receiving a network address acquisition request from a second terminal, a server queries, through a stored correspondence relationship including a sharing link, a network address required by the second terminal, and then sends the network address to the second terminal, and the second terminal establishes a connection with a first terminal having the network address according to the network address and receives screen information of the first terminal; the technical effect that the second terminal can share the screen information of the first terminal under the condition that the screen sharing application program is not required to be installed and complicated data operation is not required to be carried out is achieved.

In practical application, when the first terminal shares the screen information, the first terminal may synchronize information about a user shared screen to the server, so that the server manages the screen sharing condition of the user on the first terminal, and meanwhile, the second terminal may further obtain a network address of the first terminal from the server to establish a connection with the first terminal, thereby receiving the screen information of the first terminal sent by the first terminal. In practice, see the steps shown in fig. 4A.

Fig. 4A is a flowchart illustrating a screen information sharing method according to still another exemplary embodiment, where as shown in fig. 4A, the screen information display method is applied to the implementation environment shown in fig. 1, and includes the following steps.

In step 401, the first terminal generates a sharing link when the screen sharing application receives a screen sharing instruction.

In practical applications, when the first terminal receives a screen sharing instruction of the user on the screen sharing application, a corresponding sharing link is generated, and a method for generating the sharing link may be as shown in fig. 4B.

FIG. 4B is a flowchart illustrating the time when a shared link is generated in accordance with an illustrative embodiment.

In step 401a, a user account logged in the screen sharing application is acquired.

After the first terminal receives a screen sharing instruction sent by a user on the screen sharing application program, the first terminal may acquire a user account number logged in by the user in the screen sharing application program, where the user account number is used to identify different users.

In step 401b, when the user account does not set the sharing password, a sharing link is generated for the user account by using the timestamp.

In a possible implementation manner, a user sets a user account in the screen sharing application, and the first terminal may generate a unique sharing link for the user account by using the current timestamp, where the sharing link means that a specific user shares screen information of the first terminal at a specific time point.

In step 402a, the first terminal transmits the generated sharing link to a server corresponding to the screen sharing application.

The first terminal sends the generated sharing link to the server, for example, the generated sharing link may be sent to the server by using the user account.

In step 402b, the first terminal shares the generated sharing link to the second terminal.

It should be noted that, in actual implementation, the steps 402a and 402b are not strictly limited in sequence, and the step 402a may be executed first and then the step 402b may be executed, the step 402b may be executed first and then the step 402a may be executed, or the step 402a and the step 402b may be executed simultaneously.

In step 403a, the server receives the sharing link, and stores the sharing link, the user account, and the network address of the first terminal.

After receiving the message encapsulated with the shared link sent by the first terminal, the server can analyze the message to obtain a corresponding relationship including the shared link, and the corresponding relationship also includes a user account corresponding to the shared link and a network address of the first terminal, so that the server can store the shared link, the user account and the network address as a group of corresponding relationship.

In step 403b, the second terminal acquires the shared link, opens the shared link using the browser, and generates a network address acquisition request.

When the second terminal accesses the shared link through the browser, the second terminal may be triggered to generate a network address acquisition request corresponding to the shared link.

It should be noted that, in actual implementation, the steps 403a and 403b are not strictly limited in sequence, and the step 403a may be executed first and then the step 403b may be executed, the step 403b may be executed first and then the step 403a may be executed, or the step 403a and the step 403b may be executed simultaneously.

In step 404, the second terminal sends the network address acquisition request to the server.

Since the server stores the network address corresponding to the shared link, the second terminal may transmit a network address acquisition request corresponding to the shared link to the server.

In step 405, the server receives a network address acquisition request sent by the second terminal.

In step 406, the server queries the stored network address of the first terminal corresponding to the shared link.

After the server obtains the request according to the network address corresponding to the shared link sent by the second terminal, the server may query the stored corresponding relationship including the shared link, where the corresponding relationship includes the network address of the corresponding first terminal, and send the network address to the second terminal.

In step 407, the server transmits the network address of the first terminal corresponding to the shared link to the second terminal.

In step 408, the second terminal obtains the network address of the first terminal.

In step 409, the second terminal establishes a connection with the first terminal according to the network address of the first terminal.

And after the second terminal acquires the network address of the first terminal, establishing connection with the first terminal based on the WebRTC technology.

In step 410, the first terminal sends the screen information of the first terminal to the second terminal according to the connection established with the second terminal.

In step 411, the second terminal receives and synchronously displays the screen information of the first terminal sent by the first terminal in real time.

After the first terminal and the second terminal are connected, the first terminal can send the screen information of the first terminal to the second terminal, and the second terminal receives and synchronously displays the screen information of the first terminal sent by the first terminal in real time, so that the purpose that the first terminal shares the screen information of the first terminal to the second terminal is achieved.

In step 412, the first terminal receives a sharing stop instruction for instructing to stop screen sharing, and stops sending the screen information of the first terminal to the second terminal.

It should be noted that, in the process of screen sharing, the first terminal may receive a sharing stop instruction from the user on the screen sharing application program for instructing to stop screen sharing, and at this time, even if the first terminal remains connected to the second terminal, the first terminal stops sending the screen information of the first terminal to the second terminal.

In step 413, the first terminal transmits a sharing stop notification to the server using the user account.

After receiving the sharing stop instruction, the first terminal stops sending screen information to the second terminal and sends a sharing stop notification about the specific user account to the server.

In step 414, the server deletes the correspondence corresponding to the user account, and does not send the network address of the first terminal corresponding to the user account to the second terminal any more.

And the server receives a sharing stop notification of the specific user account from the first terminal, and the sharing stop notification is used for triggering the server to delete the stored corresponding relation corresponding to the specific user account.

Optionally, since the first terminal has stopped sending the screen information of the first terminal to the second terminal, at this time, the server may send a notification that the first terminal stops screen sharing to the second terminal after deleting the corresponding relationship including the user account, so as to prompt the second terminal not to send a related network address acquisition request to the server any more, and even if the second terminal still sends the related network address acquisition request to the server, the server does not respond to the second terminal any more.

In addition, in a possible implementation manner, the first terminal may not be able to successfully send the shared link to the server due to instability of the network, in this case, the server does not store the corresponding relationship including the shared link, at this time, if the server receives a network address acquisition request related to the shared link from the second terminal, the server does not inquire the corresponding relationship including the shared link, and at this time, the server may send the prompt information related to the inquiry result to the second terminal.

The prompt information sent by the server may be a text prompt, a voice prompt, or a music prompt, which is not limited herein.

In addition, after the first terminal generates the sharing link, the sharing link is packaged in the message body, and the message is sent to the server by taking the network address of the first terminal as the source address of the message, so that the server can analyze the network address of the first terminal and the user account number in the sharing link and perform corresponding storage after receiving the message, and management of screen sharing conditions of different users in the screen sharing application program of the first terminal can be enhanced through the server.

Meanwhile, the sharing link is generated through the user account and the timestamp, so that the sharing link has uniqueness, and the second terminal can be ensured to accurately acquire the network address of the first terminal according to the sharing link.

Finally, after receiving the sharing stop notification from the specific user of the first terminal, the server deletes the stored binding relationship associated with the user account of the user, so that the second terminal cannot acquire the network address corresponding to the user account from the server any more, and therefore the second terminal cannot acquire the screen information of the first terminal with the network address, and the security and controllability of screen sharing are guaranteed.

In practical implementation, in order to avoid that other users can optionally share the screen information of the first terminal after obtaining the sharing link, the first terminal may generally set a corresponding sharing password for the sharing link, and only when the second terminal provides a correct sharing password, the second terminal is allowed to obtain the network address of the first terminal from the server, so as to share the screen information of the first terminal. At this time, after step 401a, step 401c in fig. 4B is executed.

In step 401c, when the user account is set with the sharing password, a sharing link is generated for the user account by using the timestamp and the sharing password.

The user sets a corresponding sharing password in the screen sharing application program, and at the moment, the first terminal can generate a unique and safe sharing link for the user account by using the current timestamp and the sharing password, the sharing link means screen information shared by a specific user at a specific time point, and the shared screen information is provided with the sharing password.

Correspondingly, step 403a needs to be replaced by step 415a, which is specifically referred to fig. 4C.

In step 415a, the server receives the sharing link, and stores the sharing link, the user account, the sharing password, and the network address of the first terminal.

After receiving the sharing link sent by the first terminal by using the user account, the server may obtain the sharing link, the user account, the sharing password in the sharing link, and the network address of the first terminal.

Optionally, after receiving the message encapsulated with the shared link sent by the first terminal, the server may analyze the message to obtain a network address and a user account of the first terminal that sends the message, and analyze the shared link in the message body and a shared password included in the shared link, and the server may store the shared link, the user account, the shared password, and the network address as a set of corresponding relationships.

Since the first terminal sets the sharing password, when the second terminal wants to share the screen information of the first terminal, the password needs to be transmitted to the server using the sharing link, and step 403b needs to be replaced with step 415 b.

In step 415b, the second terminal acquires the shared link, opens the shared link using the browser, and generates a network address acquisition request including the password.

And when the second terminal accesses the sharing link through the browser, displaying a password input box to enable the second terminal to input a password, and after submitting the password, generating a network address acquisition request which corresponds to the sharing link and contains the password by the second terminal.

It should be noted that, the step 415a and the step 415b are not strictly limited in order in actual implementation, and the step 415a may be executed first and then the step 415b may be executed, the step 415b may be executed first and then the step 415a may be executed, or the step 415a and the step 415b may be executed at the same time.

Correspondingly, steps 404 to 407 are replaced with steps 416 to 420.

In step 416, the second terminal sends the network address acquisition request containing the password to the server.

Since the server stores the network address corresponding to the shared link, the second terminal may send a network address acquisition request corresponding to the shared link to the server, where the network address acquisition request includes the password input by the second terminal.

In step 417, the server receives the network address acquisition request containing the password sent by the second terminal.

In step 418, the server queries the stored network address of the first terminal and the shared password corresponding to the shared link.

Since the server stores not only the network address corresponding to the shared link but also the shared password corresponding to the shared link, the second terminal needs to pass the authentication of the shared password before acquiring the network address from the server.

Therefore, after receiving the network address acquisition request containing the password, the server firstly queries the shared password corresponding to the shared link, so as to facilitate subsequent password authentication.

In step 419, the server checks whether the password in the network address acquisition request transmitted by the second terminal is the same as the shared password corresponding to the stored shared link.

When the server queries the shared password corresponding to the shared link, it may be detected whether the password in the network address acquisition request sent by the second terminal is the same as the shared password according to the shared password.

In step 420, when the password in the network address acquisition request is the same as the shared password corresponding to the stored shared link, the server transmits the network address of the first terminal corresponding to the shared link to the second terminal.

The server detects whether the password in the network address acquisition request sent by the second terminal and related to the shared link is the same as the shared password according to the inquired shared password corresponding to the shared link, and sends the network address of the first terminal corresponding to the shared link inquired at the same time to the second terminal when the detection result is the same.

In a possible implementation manner, if the password in the network address acquisition request sent by the second terminal is different from the password queried by the server due to other reasons, the server may send a prompt message that the password is wrong to the second terminal, and may also request the second terminal to resend the network address acquisition request including the correct password.

The subsequent process can refer to steps 408 to 414, which are not described herein.

In summary, according to the screen information sharing method provided in the embodiment of the present disclosure, the shared link is generated through the user account, the timestamp, and the shared password, so that the shared link has uniqueness, and thus it can be ensured that the second terminal accurately obtains the network address of the first terminal according to the shared link, and the shared link is set by using the shared password, so that the second terminal can share the screen information of the first terminal only through verification of the shared password when accessing the shared link, thereby avoiding other terminals without the shared password from sharing the screen information of the first terminal, and improving the security of screen sharing.

In actual implementation, the second terminal may directly receive the shared link sent by the first terminal to obtain the network address of the first terminal, so as to establish a connection with the first terminal and then receive the screen information of the first terminal sent by the first terminal. See in particular the steps shown in fig. 5.

Fig. 5 is a flowchart illustrating a screen information sharing method according to still another exemplary embodiment, and the screen information display method, as shown in fig. 5, applied in the implementation environment shown in fig. 1 includes the following steps.

In step 501, the first terminal generates a sharing link when the screen sharing application receives a screen sharing instruction.

In step 502, the first terminal sends the generated shared link to the second terminal.

After the first terminal generates the sharing link, the first terminal may directly send the message body of the sharing link to the second terminal.

In step 503, the second terminal receives the sharing link, opens the sharing link using the browser, and acquires the network address of the first terminal.

After receiving the message body of the shared link, the second terminal can resolve and obtain the source network address of the shared link, which is also the network address of the first terminal sending the shared link.

In step 504, the second terminal establishes a connection with the first terminal according to the network address of the first terminal.

And establishing connection with the first terminal at the second terminal based on the WebRTC technology according to the network address of the first terminal.

In step 505, the first terminal sends the screen information of the first terminal to the second terminal according to the connection established with the second terminal.

In step 506, the second terminal receives and synchronously displays the screen information of the first terminal sent by the first terminal.

On the basis that the first terminal and the second terminal are successfully connected, the second terminal can receive and synchronously display the screen information of the first terminal, which is sent by the first terminal in real time, so that the purpose that the first terminal shares the screen information of the first terminal to the second terminal is achieved.

In step 507, the first terminal receives a sharing stop instruction for instructing to stop screen sharing. And stopping sending the screen information of the first terminal to the second terminal.

It should be noted that, during the screen sharing process, the first terminal may receive a sharing stop instruction from the user on the screen sharing application for instructing to stop the screen sharing, and at this time, even if the first terminal remains connected to the second terminal, the first terminal stops sending the screen information of the first terminal to the second terminal, so that the second terminal cannot display the screen information of the first terminal any more.

Unlike the above two embodiments, the second terminal does not receive any notification about the first terminal stopping the screen sharing at this time.

In addition, the sharing link is generated through the user account and the timestamp, so that the sharing link has uniqueness, and the second terminal can be ensured to accurately acquire the network address of the first terminal according to the sharing link.

Finally, after the first terminal receives the sharing stop instruction from the user, the screen information of the first terminal is stopped being sent to the second terminal, and the second terminal can not display the screen information of the first terminal any more, so that the safety and the controllability of the screen sharing of the first terminal are ensured.

To sum up, in the screen information sharing apparatus provided in the present disclosure, the first terminal shares the sharing link generated by the screen sharing application to the second terminal, so that the second terminal can obtain the network address of the first terminal after accessing the sharing link, so as to establish a connection with the first terminal according to the network address, and the first terminal synchronizes the screen information to the second terminal according to the established connection; the technical effect that the second terminal can share the screen information of the first terminal under the condition that screen sharing application program does not need to be installed and complex data operation does not need to be carried out is achieved.

In addition, a sharing link is generated through the user account and the timestamp, so that the sharing link has uniqueness, and the second terminal can be ensured to accurately acquire the network address of the first terminal according to the sharing link; on the basis, the sharing link can be set by using the sharing password, so that the second terminal can share the screen information of the first terminal only by verifying the sharing password when accessing the sharing link, thereby avoiding other terminals without the sharing password from sharing the screen information of the first terminal, and improving the security of screen sharing.

Meanwhile, after the first terminal generates the sharing link, the sharing link and the user account are packaged in the message body, and the message is sent to the server by taking the network address of the first terminal as the source address of the message, so that the server can analyze the network address, the sharing link and the user account of the first terminal and perform corresponding storage after receiving the message, and management of screen sharing conditions of different users in the screen sharing application program of the first terminal can be enhanced through the server.

Finally, the second terminal acquires the network address of the first terminal from the server through the shared link, and when the binding relation corresponding to the shared link stored in the server is deleted, the second terminal cannot acquire the network address of the first terminal from the server, so that the second terminal cannot establish connection with the first terminal, and therefore the second terminal cannot continuously receive and display the screen information of the first terminal, and the safety and controllability of screen sharing are guaranteed.

Fig. 7A is a block diagram illustrating a screen information sharing apparatus according to still another exemplary embodiment, which is applied to the server 130 in the implementation environment shown in fig. 1, as shown in fig. 7A, and includes, but is not limited to: a first receiving module 701, a querying module 702 and a sending module 703.

In actual implementation, before sharing the shared link generated by the screen sharing application program for the second terminal, the first terminal may encapsulate the shared link in a message body, and send the message encapsulated with the shared link to the server with the network address of the first terminal as the source address of the message. After receiving the message, the server may analyze and obtain the sharing link, the user account in the sharing link, and the network address of the first terminal.

Optionally, the first terminal may further encapsulate a shared password set by the user in the screen sharing application program in the message body, so that the server may parse and obtain the shared link, the user account in the shared link, the shared password, and the network address of the first terminal after receiving the message.

The detecting sub-module 703a may be configured to detect whether the password in the network address obtaining request received by the first receiving module 701 is the same as the stored shared password corresponding to the shared link.

Since the server can store not only the network address corresponding to the shared link but also the shared password corresponding to the shared link, the second terminal needs to pass the authentication of the shared password before acquiring the network address from the server.

The sending sub-module 703b may be configured to send the network address of the shared link to the second terminal when the detecting sub-module 703a detects that the password in the network address obtaining request is the same as the stored shared password corresponding to the shared link.

The deleting module 707 may be configured to delete the stored correspondence corresponding to the user account.

In summary, in the screen information sharing apparatus provided in this disclosure, after receiving a network address acquisition request from a second terminal, a server queries, through a stored correspondence relationship including a sharing link, a network address required by the second terminal, and then sends the network address to the second terminal, and the second terminal establishes a connection with a first terminal having the network address according to the network address and receives screen information of the first terminal; the technical effect that the second terminal can share the screen information of the first terminal under the condition that the screen sharing application program is not required to be installed and complicated data operation is not required to be carried out is achieved.

Meanwhile, the server stores the sharing password corresponding to the sharing link, and only when the password included in the network address acquisition request sent by the second terminal to the server through the sharing link is the same as the sharing password stored in the server, the server sends the network address corresponding to the sharing link to the second terminal, so that other terminals without the sharing password are prevented from sharing the screen information of the first terminal, and the screen sharing safety is ensured.
