The embodiment of the application provides a network communication method which is applied to message transmission among different application programs and can be applied to a network communication device shown in fig. 1. Wherein the network communication device includes: a transmitting end, a receiving end and a message channel. The figure is divided into two layers according to a layering mode: an application layer and a transport layer. The application layer comprises at least two hosts, and the sending end and the receiving end belong to different hosts. In one embodiment, each host contains a plurality of different applications. The application layer can generate the first data information or the second data information of the appointed theme according to the convention, and the preset packet field is used for representing the cooperative control command and the calculation data in the first data information or the second data information. The application layer transmits the first data information or the second data information to the transport layer. The application layer comprises a transmitting end and a receiving end. The method comprises the steps that a sending end generates first data information according to a theme, wherein the first data information carries information of the sending end, the theme message and a corresponding message execution queue; the sending end listens to the second data information through the network port and checks the second data information to judge whether the subject message is fed back or not. The receiving end monitors and checks the first data information in the message channel through the network port to judge whether the subject message is subscribed; the receiving end receives the subscribed first data information and sorts the subject information according to the information execution queue so as to be executed later; the receiving end generates feedback information according to the subject message, and generates second data information according to the sending end information and the feedback information. In the embodiments of the present application, the theme message is set in a user-defined manner according to different usage scenarios, the sender sends the theme a, and the receiver can receive the information by subscribing to the theme a. In one embodiment, the transport layer is a message channel that is operatively associated with the sender and receiver, respectively. The message channel can provide a server-free and expandable network communication capability for the nodes of each application layer, and broadcast all the first data information or the second data information. The message channel receives first data information sent by a sending end; the message channel receives second data information sent by the receiving end. The host may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable smart devices.
In one embodiment, as shown in fig. 2, a network communication method is provided, and the method is applied to the network communication device in fig. 1, for illustration, and includes the following steps:
step 201, receiving, through a message channel, first data information sent by a sender, where the first data information carries sender information, a subject message, and a corresponding message execution queue.
The first data information carries the information of the transmitting end, the subject message and the corresponding message execution queue. The subject message may be a string or other structure that classifies the type of information that the system notification encapsulates. The sender information is a sender identifier, and is used for indicating the source of the subject message of the receiving end. When the sender packages the subject message into the first data information, the sender can unpack the subject message into a plurality of data packets, and each data packet carries a message execution queue corresponding to the subject message because the maximum lengths of the first data information and the second data information are fixed in the application.
The message channel receives first data information sent by the sending end. When the communication is multiparty, namely when the sending end needs to send one piece of information to a plurality of receiving ends in the network, the sending end adopts a theme communication mode, packages the theme message into first data information, and sends the first data information into a message channel in a broadcast address mode, so that the receiving end can acquire the first data information conveniently. The receiving end can monitor all the first data information according to the message execution queue and integrate all the first data information to obtain the corresponding subject message.
Step 202, the control receiving end listens to the first data information through the network port and checks the first data information to judge whether the subject message is subscribed.
The receiving end listens to the first data information through the network port and checks the first data information to judge whether the topic message is subscribed. The receiving end checks all the data of the sent first data information and matches the data through the subject information, so that whether the first data information is needed data information or not is judged. The receiving end can only analyze the packet header data of the first data information, thereby realizing the rapid identification of the first data information. The header data may carry the type of information.
In step 203, the control receiving end receives the first data information containing the subscribed subject message, and sorts the subject message according to the message execution queue.
The receiving end can set the buffer space of the first data information, so that the first data information is ensured not to be lost due to the size of the buffer space. The memory of the cache space may be a memory of the first data information. When splitting each first data information, the first data information includes a packet header information, where the packet header information may include information such as a total length of a data packet, a number of split packets (i.e., a total number of message execution queues), a split sequence number (i.e., a sequence number in a message execution queue), a check code, and the like. The receiving end analyzes the data in the packet header for reorganization when receiving the first data information. The time when the receiving end receives the first data information of the same subject message can be different, and when the first data information belonging to the same message execution queue is completely received, the receiving end reorganizes the received first data information according to the message execution queue. The receiving end guarantees the consistency of the sending and receiving sequence of each message in a first-in first-out queue mode in each message execution queue through the message execution queue.
Step 204, the control receiving end generates feedback information according to the ordered subject message, and generates second data information according to the sending end information and the feedback information.
The receiving end generates feedback information according to the ordered subject messages, and generates second data information according to the sending end information and the feedback information. The second data information may or may not be encrypted. In one embodiment, the first data information is encrypted by the transmitting end according to preset protocol information with the receiving end, and the receiving end determines an application program of the transmitting end through the protocol information. The protocol information may be network details such as IP, PORT, application identifier, etc. When the sending end packs the first data information, the network details can be encrypted in a certain mode, the encrypted data and the information to be sent are packed and sent to the information channel, the receiving end unpacks the data packet according to the agreed check and then the network information of the sending end is contained in the data packet, and the corresponding application program of which sending end can know when the information is returned.
In one embodiment, different encryption modes of the sending end can be set to be different, so that the receiving end can conveniently and quickly identify the sending end. In one embodiment, the first data information further includes program identifiers corresponding to the application programs one by one, and different protocol information can be set to correspond to different application programs, so that the receiving end can conveniently and quickly identify the corresponding application programs. Therefore, different application programs of the same host can be provided with corresponding message queues, the concurrent processing capacity of the same host is improved, and the situation that different application programs are always in a waiting state when other programs run is avoided.
Step 205, receiving the second data information sent by the receiving end through the message channel.
The message channel receives second data information sent by the receiving end. The second data information carries the sending end information of the first data information, the receiving end information of the executed subject message, the feedback information and the corresponding message execution queue. The transmitting end and the receiving end in the embodiment are not fixed, and the transmitting end and the receiving end may be inverted for different subject information or different information. For example, in the same subject information, the transmitting end of the first data information is the receiving end of the second data information, and the receiving end of the first data information is the transmitting end of the second data information.
According to the method, through establishing the public message channel, the two communication parties do not need to know the detailed address of the other party, only need to subscribe to the subject message, the subject message is sent to the public channel in a broadcasting mode through the data packet, and the receiver only needs to check whether the message subscribed by the receiver is received or not, so that the establishment of the exclusive channel can be reduced, and the complexity of the two communication parties and the occupancy rate of system resources are reduced.
In one embodiment, the method further comprises the steps of:
controlling the same application program of at least two different devices to respectively receive subscribed first data information;
the receiving end generates feedback information according to the subject message, and generates second data information according to the transmitting end information and the feedback information;
receiving second data information sent by a receiving end through a message channel;
the control sending end monitors and checks the second data information through the network port and judges whether the subject message is fed back or not;
and controlling the sending end to generate first data information corresponding to the receiving end one by one according to the distribution strategy weight based on the feedback information.
According to the method, the same application program can be started on two different hosts at the same time, so that the program safety can be improved, and the usability of the application program can be improved. When the same application program starts one of the two hosts respectively, for example, when the distribution strategy weight is configured to be 50, the sending end distributes the messages to different hosts for processing respectively in five times, so that the aim of balancing the load of message processing is achieved. The value range of the distribution strategy weight can be from 0 to 100, and can be determined according to the processing efficiency of the receiving end. And may be used simultaneously on more than two devices as long as the sum of the values of the distribution policy weights of all devices is 100.
As shown in fig. 3, in one embodiment, based on feedback information, the sending end is controlled to generate first data information corresponding to the receiving end one by one according to the distribution policy weight, which includes the following steps:
step 301, determining an execution state of the receiving end based on the feedback information.
The transmitting end determines the execution state of the receiving end based on the feedback information. The transmitting end at least stores all the theme information transmitted to the receiving end and the transmitting time of the theme information. The sending end can determine the time, execution time, feedback time and the like of the receiving end to receive the theme information according to the feedback information.
The sending end can determine whether the receiving end normally executes and the execution efficiency according to the feedback information of the receiving end and the subject information sent to the receiving end. When the execution efficiency is lower than a preset threshold, the sending end judges that the receiving end is abnormal in execution and needs to adjust the distribution strategy weight. When the transmitting end transmits the first data information to the receiving end, but does not receive the second data information fed back by the receiving end within a preset time, the transmitting end judges that the receiving end fails, the executing abnormality occurs, and the distribution strategy weight also needs to be adjusted.
Step 302, when it is determined that the receiving end performs abnormality, the distribution policy weight is adjusted according to the feedback information.
When the receiving end is determined to be abnormal, the sending end adjusts the distribution strategy weight according to the feedback information. For example, when the receiving end fails, the sending end may adjust the distribution policy weight to be a full value, so as to forward all the subject information originally predicted to be distributed to the receiving end to another host; when the processing efficiency of the receiving end is too low, the sending end can properly adjust the distribution strategy weight to be a low value so as to forward the theme information part originally pre-distributed to the receiving end to another host.
Step 303, the sending end is controlled to generate first data information corresponding to the receiving end one by one according to the adjusted distribution strategy weight.
And the sending end controls the sending end to generate first data information corresponding to the receiving end one by one according to the adjusted distribution strategy weight.
In one embodiment, a network communication method includes:

the method comprises the steps that a sending end generates first data information according to a theme, wherein the first data information carries information of the sending end, the theme message and a corresponding message execution queue;
