It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment provides a communication method and device between clients, electronic equipment and a storage medium, which are applied to a server in a network video live broadcast system. The client live broadcast application program can be installed on a mobile terminal such as a mobile phone. The client browser can be installed on a desktop computer and can also be installed on mobile terminals such as mobile phones. The user can watch the live broadcast content through a client live broadcast application program on the mobile terminal and can also watch the live broadcast content through a client browser. The client live application program and the client browser can realize mutual communication through the server.
Fig. 1 is a schematic flow chart of a communication method between clients according to an embodiment of the present invention, and referring to fig. 1, the method of the present embodiment is applied to a server in a network video live broadcast system, and the method may include:
The first thread is a single thread for managing a plurality of network connections. The second thread is a business processing thread which specifically processes reading, sending and other operations. The first thread and the second thread can communicate by means of wait, notify and the like. The first network connection is a network connection initiated by a client live broadcast application program. The first thread may allocate the received first network connection to a queue of the second thread, facilitating the second thread to obtain the first network connection from its queue.
Fig. 2 is a schematic structural diagram illustrating a structure of managing multiple connections through a single thread according to an embodiment of the present invention. Referring to fig. 2, both the client live application and the client browser can access the server of the live system through the first thread, and the specific operations of reading, sending, and the like are completed by other service processing threads, such as the second thread, the third thread, and the like. Because the number of people online at the same time of the live video application is possibly large, in the embodiment, a JAVA NIO non-blocking mode is adopted to realize that the client live application program and the client browser efficiently access to the server of the live broadcast system. JAVA NIO is an abbreviation of JAVA New IO, and is a New API (Application Programming Interface) provided in jdk 1.4. The non-blocking mode of Java NIO can manage a plurality of network connections by using a single thread, and the specific operations of reading, sending and the like are completed by other service processing threads, so that the Java NIO non-blocking mode is adopted to realize that a client live broadcast application program and a client browser are efficiently accessed into a server of a live broadcast system, the access capability of the server can be improved, and the server can effectively bear the establishment of a large number of connections and data transmission work. The plurality of network connections comprise network connections of the client live broadcast application programs and network connections of the client browsers, wherein the number of the network connections of the client live broadcast application programs can be multiple, and the number of the network connections of the client browsers can also be multiple.
And 102, reading a binary string sent by the client live broadcast application program by the second thread according to the first network connection.
The first thread receives the first network connection, and the first network connection can be established between the client live broadcast application program and the server. In order to realize efficient data transmission between the client live broadcast application program and the client browser, both ends of the client live broadcast application program and the client browser are compatible with a binary protocol. After the client live broadcast application program establishes first network connection with the server, the client live broadcast application program can serialize data objects to be transmitted into binary strings and transmit the binary strings, and the second thread reads the binary strings transmitted by the client live broadcast application program according to the first network connection.
And 103, the first thread receives a second network connection and distributes the received second network connection to the second thread or a third thread.
The second network connection is a network connection initiated by the client browser. The client browser may be an IE browser, Google Chrome or firefox browser, etc.
And the first thread receives the second network connection, namely the second network connection can be established between the client browser and the server.
The first thread may assign the received second network connection directly to the second thread, through which the binary string is sent to the client browser. In another embodiment, the first thread may also allocate the received second network connection to other business processing threads other than the second thread, for example, to a third thread, and specifically, the first thread may first store the read binary string in a buffer, and after receiving the second network connection, the first thread may allocate the second network connection to the third thread, and the third thread reads the binary string from the buffer and sends the binary string to the client browser.
And 104, the second thread or the third thread sends the binary string to the client browser, so that the client browser performs analysis operation on the binary string.
According to the communication method between the clients, the first network connection and the second network connection are received through the first thread, the received first network connection is distributed to the second thread, and the second thread reads a binary string sent by a client live broadcast application program according to the first network connection; the first thread distributes the received second network connection to a second thread or a third thread, the second thread or the third thread sends the binary string sent by the second thread reading client live broadcast application program to the client browser, so that the client browser carries out analysis operation on the binary string, thus, a plurality of network connections (a first network connection and a second network connection) can be managed through one single thread (the first thread), specific operations such as reading, sending and the like are handled by other processing threads (the second thread or the third thread), management of the network connections and data operation after connection are separately arranged and are respectively handled by different threads, and therefore the access capability of a server in a video live broadcast system can be improved; furthermore, data sent by the client live application program is a binary string, and data received by the client browser is also a binary string, so that the binary string sent by the client live application program can be directly transmitted to the client browser through the server, and operations such as unpacking or protocol conversion are not required in the process, and the data transmission efficiency is improved.
Fig. 3 is a flowchart illustrating a process of sending a binary string to a client browser by a second thread or a third thread according to an embodiment of the present invention. Referring to fig. 3, according to an embodiment of the present invention, the second thread or the third thread sends the binary string to the client browser, so that the client browser performs a parsing operation on the binary string (step 104), which may include:
WebSocket is a protocol that HTML5 initially provides for full-duplex communication over a single TCP connection. The method is mainly characterized in that the server can actively push information to the client, and the client can also actively send the information to the server.
Because some client browsers may not support the WebSockets communication mechanism, in order to be compatible with different client browsers, especially some low-version browsers, the binary string is sent to the client browser in a corresponding communication manner according to a communication protocol supported by the client browser, and it is necessary to determine whether the client browser supports the WebSocket communication mechanism before the second thread or the third thread sends the binary string to the client browser. If the WebSocket communication mechanism is supported, the WebSocket communication mechanism can be directly adopted for communication, and if the WebSocket communication mechanism is not supported, the communication is automatically degraded to the communication mechanisms such as long polling and the like supported by the low-version browser for communication.
The method for judging whether the client browser supports the WebSocket communication mechanism can detect whether the browser supports WebSocks or not through a browser console (such as Firebug or Chrome development tool), and if not, the WebSocket command returns 'undefined'.
By the judgment, if the client browser supports the WebSocket communication mechanism, executing step 1042, otherwise executing step 1044.
And 1042, establishing a WebSocket connection with the client browser.
In this embodiment, if the client browser supports the WebSocket communication mechanism, the script of the client browser may call the WebSocket interface encapsulated in the communication interface encapsulation package to establish the WebSocket connection.
The communication interface packaging packet is installed in the client browser, and at least a network socket interface is packaged in the communication interface packaging packet. Therefore, if the client browser supports the WebSocket communication mechanism, the network socket interface packaged in the communication interface packaging packet can be directly adopted, and the WebSocket connection can be established quickly.
In an embodiment of the present invention, if the client browser supports a WebSocket communication mechanism, a WebSocket interface packaged in socket. The socket.IO is a communication interface packaging packet which is installed in the client browser, and interfaces of various communication mechanisms such as Websocket, Long Polling (Long Polling) and Flashsocket are packaged in the socket.IO, so that the communication mechanisms such as Websocket, Long Polling and Flashsocket are supported.
In this embodiment, if the client browser supports a WebSocket communication mechanism, the JavaScript of the client browser calls a WebSocket interface encapsulated in socket.
After the WebSocket connection is established between the server and the client browser, if the second thread reads the binary string from the client live broadcast application program, the server does not need to generate the binary string to the client browser after receiving a binary string acquisition request sent by the client browser, but can directly generate the binary string to the client browser, so that the data transmission efficiency can be improved.
Furthermore, both ends of the client live broadcast application program and the client browser are compatible with binary protocols, the client live broadcast application program can organize data packets only by serializing data to be sent, and the client browser can obtain the data packets only by deserializing received binary strings, so that conversion work of protocols due to the fact that the protocols at both ends are different can be avoided, and data transmission efficiency can be further improved.
If the client browser does not support the WebSocket communication mechanism, a long polling communication mechanism can be adopted, and under the long polling communication mechanism, the client browser can actively initiate a binary string acquisition request to the server. And under the condition that the client browser does not actively initiate the binary string acquisition request, the server does not actively transmit the binary string to the client browser.
And 1045, the second thread or the third thread transmits the binary string to the client browser according to the binary string acquisition request.
And the server transmits the binary string to the client browser according to the binary string acquisition request. Specifically, the binary string may be transmitted to the client browser through the second thread or the third thread according to the binary string acquisition request, so that the client browser performs a parsing operation on the binary string.
In this embodiment, if the client browser does not support the WebSocket communication mechanism, the server waits for receiving a binary string acquisition request actively initiated by the client browser, and the server transmits the binary string to the client browser according to the binary string acquisition request, so that the client browser performs an analysis operation on the binary string, thereby ensuring that data transmission can be performed normally even if the client browser does not support the WebSocket communication mechanism.
Specifically, if the client browser does not support the WebSocket communication mechanism, a script of the client browser automatically calls a communication interface supported by the client browser, such as a long connection interface, packaged in a communication interface packaging packet to establish a network connection.
In this embodiment, a plurality of communication interfaces are encapsulated in the communication interface encapsulation packet, and if the client browser does not support the WebSocket communication mechanism, the communication interface supported by the client browser may be automatically used to establish a network connection, for example, the long connection interface supported by the low-version browser may be automatically used to establish a network connection, so that different browsers may be better compatible to implement network communication.
Further, if the client browser does not support the WebSocket communication mechanism, the JavaScript of the client browser can call the long polling interface encapsulated in socket.
Fig. 4 is a schematic structural diagram of a communication device between clients according to an embodiment of the present invention, and referring to fig. 4, the device of the present embodiment is applied to a server in a network video live broadcast system, and the device may include: a connection management module 11 and a data processing module 12.

The first thread is a single thread for managing a plurality of network connections. The second thread is a business processing thread which specifically processes reading, sending and other operations. The first thread and the second thread can communicate by means of wait, notify and the like. The first network connection is a network connection initiated by a client live broadcast application program. The first thread may allocate the received first network connection to a queue of the second thread, facilitating the second thread to obtain the first network connection from its queue.
Both the client live broadcast application program and the client browser can access a server of the live broadcast system. In this embodiment, a JAVA NIO non-blocking mode is used to implement that the client live application and the client browser efficiently access to the server of the live system. JAVA NIO is an abbreviation of JAVA New IO, and is a New API (Application Programming Interface) provided in jdk 1.4. The non-blocking mode of Java NIO can manage multiple network connections by using a single thread, and the specific operations of reading, sending, and the like are completed by other service processing threads, so in this embodiment, the Java NIO non-blocking mode is used to implement that the client live broadcast application program and the client browser efficiently access to the server of the live broadcast system, which can improve the access capability of the server, and enable the server to effectively carry a large number of connections for establishment and data transmission. The plurality of network connections comprise network connections of the client live broadcast application programs and network connections of the client browsers, wherein the number of the network connections of the client live broadcast application programs can be multiple, and the number of the network connections of the client browsers can also be multiple.
The second network connection is a network connection initiated by the client browser. The client browser may be an IE browser, Google Chrome or firefox browser, etc.
And the first thread receives the second network connection, namely the second network connection can be established between the client browser and the server. The first thread may assign the received second network connection directly to the second thread, through which the binary string is sent to the client browser. In another embodiment, the first thread may also allocate the received second network connection to other business processing threads other than the second thread, for example, to a third thread, and specifically, the first thread may first store the read binary string in a buffer, and after receiving the second network connection, the first thread may allocate the second network connection to the third thread, and the third thread reads the binary string from the buffer and sends the binary string to the client browser.
The data processing module 12 is configured to read, by the second thread according to the first network connection, a binary string sent by the client live broadcast application program; and sending the binary string to the client browser through the second thread or the third thread so that the client browser performs parsing operation on the binary string.
As described above, in this embodiment, both ends of the client live application and the client browser are compatible with the binary protocol. When the client live application program communicates with the two ends of the client browser through the server, the server can directly transmit the binary string sent by the client live application program to the client browser, data transmission can be completed without unpacking processing or data conversion, and transmission efficiency is effectively improved.
According to an embodiment of the present invention, the data processing module 12 is specifically configured to: if the client browser supports a WebSocket communication mechanism, establishing network socket connection with the client browser, and transmitting the binary string to the client browser through the second thread or the third thread according to the network socket connection, so that the client browser performs analysis operation on the binary string; and both ends of the client browser and the client live broadcast application program are compatible with a binary protocol.
WebSocket is a protocol originally provided by HTML5 for full-duplex communication over a single TCP connection. The method is mainly characterized in that the server can actively push information to the client, and the client can also actively send the information to the server.
After the WebSocket connection is established between the server and the client browser, if the second thread reads the binary string from the client live broadcast application program, the server does not need to generate the binary string to the client browser after receiving a binary string acquisition request sent by the client browser, but can directly generate the binary string to the client browser, so that the data transmission efficiency can be improved.
Furthermore, both ends of the client live broadcast application program and the client browser are compatible with binary protocols, the client live broadcast application program can organize data packets only by serializing data to be sent, and the client browser can obtain the data packets only by deserializing received binary strings, so that conversion work of protocols due to the fact that the protocols at both ends are different can be avoided, and data transmission efficiency can be further improved.
If the client browser supports a network socket communication mechanism, a script of the client browser calls a network socket interface packaged in a communication interface packaging packet to establish network socket connection, and the second thread or the third thread transmits the binary string to the client browser according to the network socket connection; the communication interface packaging packet is installed in the client browser, and at least a network socket interface is packaged in the communication interface packaging packet. Therefore, if the client browser supports the WebSocket communication mechanism, the network socket interface packaged in the communication interface packaging packet can be directly adopted, and the WebSocket connection can be established quickly.
In an embodiment of the present invention, if the client browser supports a WebSocket communication mechanism, a WebSocket interface packaged in socket. And the second thread or the third thread transmits the binary string to the client browser according to the Websocket connection.
The socket.IO is used as a communication interface packaging packet and installed in the client browser, and interfaces of various communication mechanisms such as Websocket, Long Polling (Long Polling) and Flashsocket are packaged in the socket.IO, so that the communication mechanisms such as Websocket, Long Polling and Flashsocket are supported.
In this embodiment, if the client browser supports a WebSocket communication mechanism, the JavaScript of the client browser calls a WebSocket interface encapsulated in socket.
Since some client browsers may not support the WebSocket communication mechanism, in order to be compatible with different client browsers, the binary string is sent to the client browser in a corresponding communication manner according to a communication protocol supported by the client browser, and it is necessary to determine whether the client browser supports the WebSocket communication mechanism before the second thread or the third thread sends the binary string to the client browser. If the WebSocket communication mechanism is supported, the WebSocket communication mechanism can be directly adopted for communication, and if the WebSocket communication mechanism is not supported, the communication is automatically degraded to the communication mechanisms such as long polling and the like supported by the low-version browser for communication.
The method for judging whether the client browser supports the WebSocket communication mechanism can detect whether the browser supports WebSocks or not through a browser console (such as Firebug or Chrome development tool), and if not, the WebSocket command returns 'undefined'.
According to an embodiment of the present invention, the data processing module 12 is further specifically configured to: if the client browser does not support the network socket communication mechanism, receiving a binary string acquisition request actively initiated by the client browser, and transmitting the binary string to the client browser through the second thread or the third thread according to the binary string acquisition request, so that the client browser performs analysis operation on the binary string, and data transmission can be performed normally under the condition that the client browser does not support the Websocket communication mechanism.
In this embodiment, if the client browser does not support the WebSocket communication mechanism, the data processing module automatically calls, through a script of the client browser, a communication interface supported by the client browser and encapsulated in a communication interface encapsulation package to establish a network connection, where the communication interface encapsulation package is installed in the client browser; receiving a binary string acquisition request actively initiated by the client browser; and the second thread or the third thread transmits the binary string to the client browser according to the binary string acquisition request, so that if the client browser does not support a WebSocket communication mechanism, a communication interface supported by the client browser packaged in the communication interface packaging packet can be directly adopted to establish network connection, and the rapid establishment of the network connection is facilitated.
In an embodiment of the present invention, if the client browser does not support the web socket communication mechanism, a long polling communication mechanism may be used to establish a network connection between the server and the client browser, and under the long polling communication mechanism, the client browser may actively initiate a binary string acquisition request to the server. And under the condition that the client browser does not actively initiate the binary string acquisition request, the server does not actively transmit the binary string to the client browser.
In an embodiment of the present invention, the data processing module calls a long polling interface encapsulated in socket.io through JavaScript of the client browser to establish a network connection. Therefore, the long connection can be established based on the existing socket.
In the communication device between clients provided by the embodiment of the present invention, the connection management module receives the first network connection and the second network connection through the first thread, allocates the received first network connection to the second thread, and allocates the received second network connection to the second thread or the third thread; the data processing module reads a binary string sent by a client live application program through the second thread according to the first network connection, and sends the binary string to the client browser through the second thread or the third thread so that the client browser performs analysis operation on the binary string, so that a plurality of network connections (a first network connection and a second network connection) can be managed through one single thread (a first thread), specific operations such as reading and sending are handled by other processing threads (the second thread or the third thread), management of the network connections and data operation after connection are separately arranged and processed by different threads, and accordingly the live broadcast access capability of a server in the video system can be improved; furthermore, data sent by the client live application program is a binary string, and data received by the client browser is also a binary string, so that the binary string sent by the client live application program can be directly transmitted to the client browser through the server, and operations such as unpacking or protocol conversion are not required in the process, and the data transmission efficiency is improved.
