Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The local area network can be a network type, the coverage range of the local area network can be within thousands of square meters and thousands of round meters generally, and the local area network has the characteristics of convenience in installation, cost saving, convenience in expansion and the like, so that the local area network can be widely applied to various offices. The local area network can realize functions of file management, application software sharing, printer sharing and the like, and can effectively protect data security and ensure normal and stable operation of the local area network by maintaining the security of the local area network in the using process. Data sharing is to enable users who use different computers and different software in different places to read data of others and perform various operations, operations and analyses.
As an example, in the related art, people have an increasing demand for data sharing, but since no corresponding identity relationship is established between users, the way of data sharing transmission is complicated. For example, the sender and the receiver need to use login as a premise, and data sharing is realized by constructing a user relationship between the sender and the receiver and then sending a message by using an instant messaging function. Or jumping out of the current App, and using other Apps establishing the user relationship to carry out data transmission communication. Therefore, in the process, data transmission of both data sharing parties is limited by data sharing based on the user relationship, and the data sharing threshold is greatly increased.
In contrast, one of the core invention points is that, for a sending terminal, the sending terminal can respond to a data sharing instruction input by a user in an application program, and search for a receiving terminal belonging to the same local area network as the sending terminal according to current network information acquired after the user authorizes the receiving terminal, and if the receiving terminal belonging to the same local area network as the sending terminal exists, the sending terminal can determine target data corresponding to the data sharing instruction and send the target data to the receiving terminal, so that when the user initiates data sharing in the application program, the sending terminal can search for other terminals located in the same local area network and send shared data to the other terminals, and under the condition of running the same application program, the sending terminal based on the same local area network can avoid constructing a user relationship to perform data sharing, thereby effectively reducing the threshold of data sharing.
Specifically, referring to fig. 1, a flowchart of steps of a data transmission method provided in the embodiment of the present invention is shown, and is applied to a sending terminal, where the method specifically includes the following steps:
for the sending terminal and the receiving terminal, the sending terminal and the receiving terminal may include a desktop computer, a notebook computer, a tablet computer, a mobile terminal and other user terminals, corresponding application programs may be run in the user terminals, and the application programs may include a life application program, an audio application program, a game application program, a job application program and the like.
In a specific implementation, the terminal may obtain the network information of the network to which the terminal belongs during the process of running the corresponding application program, so as to perform data sharing according to the network information. It should be noted that the action of acquiring the network information proposed in the embodiment of the present invention is performed under the premise of complying with the data protection regulation policy corresponding to the country of the location and obtaining the authorization given by the owner of the corresponding device.
in the process of running the application program, when a user needs to share data, the sending terminal can input a corresponding data sharing instruction into the application program, then the terminal can respond to the data sharing instruction in the application program, and according to the current network information which is acquired after the user authorizes, a receiving terminal which belongs to the same local area network as the sworn sending terminal is searched, so that the data can be sent to the receiving terminal.
The network information may include a subnet mask of the sending terminal, and the subnet mask may be used to indicate which bits of an IP address identify the subnet where the terminal is located and which bits identify the bit mask of the terminal, which may be combined with the IP address to determine the network address of the terminal. Alternatively, the subnet mask may be a 32-bit address used to mask a portion of the IP address to distinguish between the network identification and the terminal identification and to indicate whether the IP address is on the lan or wan.
In a specific implementation, in a process of processing related data, when the related data needs to be shared to another terminal, a user may share the data through a sharing path provided in an application program, and then a sending terminal may respond to a data sharing instruction in the application program, display a corresponding terminal search interface, and search, through a subnet mask of the sending terminal obtained in advance, for a receiving terminal that belongs to the same local area network as the sending terminal, so as to send the corresponding data to the receiving terminal.
Specifically, the network information may further include a first IP address of the sending terminal, the sending terminal may first search for at least one target terminal that is the same as the subnet mask of the sending terminal, and if at least one target terminal that is the same as the subnet mask is found, may further obtain a second IP address of each target terminal, and then the sending terminal may calculate the first network address of the sending terminal by using the first IP address and the subnet mask, and calculate a second network address of the target terminal by using the second IP address and the first subnet mask, and then compare the second network address of each target terminal with the first network address of the sending terminal, and use the target terminal corresponding to the second network address that is the same as the first network address as a receiving terminal belonging to the same local area network as the sending terminal.
In addition, if a second network address identical to the first network address does not exist, second prompt information aiming at the target terminal is displayed, and the second prompt information is information that each target terminal and the sending terminal are not in the same local area network.
Optionally, the subnet mask may be used to determine whether the IP addresses of different terminals are on the local area network or the wide area network, and the IP addresses may be used to represent unique addresses of the terminals, and then perform an and-operation through the subnet mask and the IP addresses to obtain network addresses of the terminals, and if the network addresses are the same, then represent that different terminals are located in the same local area network, so that the sending terminal may first search for a target terminal that is also located in the local area network through the subnet mask, then calculate network addresses of each terminal according to the and-operation of the subnet mask and the IP addresses, and further screen out a receiving terminal that is located in the same local area network as the sending terminal through a network address comparison manner to send corresponding target data to the receiving terminal, so that when a user initiates data sharing in an application program, the terminal may search for other terminals located in the same local area network and send shared data to the receiving terminal, under the condition of running the same application program, the terminals based on the same local area network can avoid constructing a user relationship for data sharing, and effectively reduce the threshold of data sharing.
In an optional embodiment, when the user inputs a corresponding data sharing instruction in the application program, the terminal may first detect whether the network is currently accessed, and execute the process of searching for the receiving terminal in the case of accessing the network; if the terminal does not access the network, the corresponding prompt information can be output to prompt the user to access the network first and then share the data.
And 103, if a receiving terminal which belongs to the same local area network as the sending terminal exists, determining target data corresponding to the data sharing instruction, and sending the target data to the receiving terminal.
In the embodiment of the present invention, when the sending terminal finds the receiving terminal belonging to the same local area network through its own IP address and subnet mask, the target data corresponding to the data sharing instruction may be determined, and then the target data is sent to the receiving terminal. The target data at least comprises one of pictures, audios, videos, documents and posts, so that when a user initiates data sharing in an application program, the terminal can search other terminals located in the same local area network and send shared data to the other terminals, and under the condition that the same application program is operated, the terminals based on the same local area network can avoid building a user relationship to carry out data sharing, so that the threshold of data sharing is effectively reduced, and meanwhile, data transmission is carried out in the same local area network, so that the stability and the transmission speed of data transmission can be effectively ensured.
In a specific implementation, after determining the target data corresponding to the data sharing instruction, the sending terminal may send the target data to the server, and send the target data to the receiving terminal through the server. Under the condition that the receiving terminal runs the same application program, after receiving a data sharing request sent by a server, the receiving terminal can execute corresponding data processing according to user operations (including operations of confirming sharing, refusing sharing and the like) of a user to which the receiving terminal belongs, and if the user confirms sharing, the receiving terminal can respond to the data receiving request, receive target data and then display the corresponding target data; if the user refuses to share, the server can obtain the response message sent by the receiving terminal and send the response message to the sending terminal, and the sending terminal displays the response message to inform the user that the data sharing is failed.
In addition, if the sending terminal does not find the receiving terminal which belongs to the same local area network as the sending terminal according to the IP address and the subnet mask of the sending terminal, the first prompt information aiming at the data sharing instruction can be displayed, and the first prompt information is the information that the terminal which belongs to the same local area network as the sending terminal does not exist so as to inform that no terminal which can perform data sharing exists nearby the belonging user.
It should be noted that the embodiment of the present invention includes but is not limited to the above examples, and it is understood that, under the guidance of the idea of the embodiment of the present invention, a person skilled in the art may also set the method according to actual requirements, and the present invention is not limited to this.
In the embodiment of the invention, the method can be applied to a sending terminal, the sending terminal can acquire the current affiliated network information, respond to a data sharing instruction input by a user in an application program, search a receiving terminal which belongs to the same local area network as the sending terminal according to the network information, determine target data corresponding to the data sharing instruction and send the target data to the receiving terminal if the receiving terminal which belongs to the same local area network as the sending terminal exists, so that when the user initiates data sharing in the application program, the terminal can search other terminals located in the same local area network and send shared data to the other terminals, and under the condition of running the same application program, the terminals based on the same local area network can avoid constructing a user relationship to carry out data sharing, thereby effectively reducing the threshold of data sharing.
In order to make the technical solutions of the embodiments of the present invention better understood by those skilled in the art, the following is an exemplary illustration by an example:
referring to fig. 2, which is a schematic diagram illustrating a data sharing process provided in an embodiment of the present invention, for a same application program run by a sending terminal and a receiving terminal, a network monitoring function may be configured in the application program, and after prompting and obtaining user authorization, the application program may monitor a network of the terminal through the network monitoring function in a foreground running process of the application program, so that when a user initiates data sharing in the application program, the user may search for a corresponding receiving terminal based on network information to perform data sharing. The specific process can comprise the following steps:
1. the application program can monitor the network of the terminal in real time, and upload the IP address of the current network and related data such as subnet mask to the server in real time when the network changes, so as to be used for later function verification.
2. When a user initiates a data sharing requirement (e.g., sharing a house source post):
the application program can firstly check whether the terminal is networked or not, and when the terminal is not networked currently, the application program can output corresponding prompt information to prompt the terminal to be networked and stop the data sharing process before the terminal is networked.
When the application program monitors that the terminal is connected with the network, the application program can judge according to the IP address and the subnet mask reported by the network monitoring, and search for the receiving terminal with the same subnet mask as the local terminal which initiates the shared data currently. For the searching process of the receiving terminal, the sending terminal can firstly search out a target terminal with the same subnet Mask, acquire the IP address of the target terminal, then respectively calculate the network address IP & Mask of each terminal (including the sending terminal and the target terminal), and then take the target terminal with the same IP & Mask as the sending terminal as the receiving terminal in the same local area network, thereby screening out the receiving terminal in the same local area network through twice filtering.
When the sharable terminal group is found, the related data such as the post ID of the current data (a post) is packaged and sent to the server, and the server can send the shared data content to the receiving terminal meeting the conditions after receiving the shared data content. The receiving terminal can confirm whether to receive data or not through the sharing request popped up in the application program, and receive the corresponding target data after the receiving is confirmed, so that when a user initiates data sharing in the application program, the terminal can search other terminals located in the same local area network and send shared data to the other terminals, and under the condition that the same application program is operated, the terminals based on the same local area network can avoid constructing a user relationship to carry out data sharing, and the threshold of data sharing is effectively reduced.
