Description
Technical Field

Background
In a large project system, the project system is generally divided into a plurality of modules according to different functions in the project system. The types of the modules can be divided into two types, one type is a service module used for processing data according to the functions of the service module, one service module corresponds to a single function, and the other type is a communication module used for transmitting data between the service modules. Namely, the project system is formed by assembling service modules with different functions and a communication module. The data transmission process in the project system comprises the following steps: and after the service module finishes processing the data, transmitting the data to the next service module through the communication module. In other words, the different business modules are like production workshops and are responsible for processing different business data, and the communication modules are like crawlers for transmitting data in the production workshops.
Generally, in actual deployment, due to different functional requirements, limitation of hardware resources, and the like, flexible assembly and deployment of the service module and the communication module are performed, and thus, a phenomenon that a plurality of service modules are deployed in the same process may occur. Based on this, data transmission in the project system is divided into intra-process data transmission (i.e., data transmission between service modules in the same process) and inter-process data transmission (i.e., data transmission between service modules of different processes). At present, data transmission in a process and data transmission between processes are transmitted in a network data transmission mode, that is, a communication module receives data transmitted by a service module sending the data, and the data is lost into a network card through a TCP/IP protocol so as to transmit the data to the service module receiving the data through the TCP/IP protocol.
Obviously, in the existing data transmission method, no matter whether the service module for transmitting data is in the same process, that is, no matter whether data transmission between processes or data transmission within processes, data is transmitted by adopting a network data transmission mode. Because the way of network data transmission has the problems of complex path, high occupancy rate of network bandwidth and low efficiency, it is important to simplify the data transmission path in the process, reduce the occupancy rate of network bandwidth and improve the transmission efficiency.

That is, these functional entities may be implemented in the form of software, or in one or more software-hardened modules, or in different networks and/or processor devices and/or microcontroller devices.
The exemplary embodiment first discloses a data transmission method, which is applied to a system comprising a plurality of processes, wherein each process comprises a communication module and at least one service module. The communication module in each process comprises a receiving container and a sending container. The sending container is used for storing the theme identification transmitted when each business module in the corresponding process sends data and the created sending object, and the receiving container is used for storing the theme identification transmitted when each business module in the corresponding process receives data and the created receiving object. It should be noted that one service module may receive data and may also send data, that is, one service module may be a service module that receives data and may also be a service module that sends data. It should be noted that the execution main body in the embodiment of the present invention may be a communication module in a process, where data transmission exists between service modules in the process or between the process and service modules of other processes.
As shown in fig. 1, the method may include the steps of:
step S110, responding to a data sending instruction of a first service module, and creating a sending object of the first service module based on a theme mark transmitted by the first service module;
step S120, searching whether a receiving object corresponding to the subject identification exists in a receiving container;
step S130, if the callback function exists, registering the callback function of the second service module corresponding to the receiving object to the sending object, so that the sending object sends the received data sent by the first service module to the second service module according to the callback function.
According to the data transmission method in the exemplary embodiment, on one hand, whether the first service module and the second service module belong to the same process is judged by searching whether a receiving object corresponding to the subject identifier exists in the receiving container, that is, whether the data transmission in the process is judged, and the judgment step is simple and easy to implement; on the other hand, if a receiving object corresponding to the topic identifier exists, namely when the first service module and the second service module belong to the same process, the callback function of the second service module is registered to the sending object of the first service module, so that the sending object sends the received data sent by the first service module to the second service module according to the callback function.
Next, the data transmission method in the present exemplary embodiment will be further described with reference to fig. 1.
In step S110, in response to an instruction of sending data by a first service module, a sending object of the first service module is created based on the topic identifier transmitted by the first service module.
In this exemplary embodiment, the first service module may be a service module that transmits the topic identifier through the first interface, and it may also be a service module that transmits data. The communication module may include a plurality of interfaces, wherein the first interface is one of the plurality of interfaces on the communication module.
After the first service module transmits the instruction of the first service module for sending data and the subject identifier to the communication module through the first interface, the communication module responds to the instruction of the first service module for sending data, and creates a sending object of the first service module based on the subject identifier transmitted by the first service module. The subject mark is used for marking the target address and the target port of the business module for receiving the data sent by the first business module. The target address may be 192.168.1.1 or 192.168.1.2, for example, which is not limited in this exemplary embodiment. The destination port may refer to, for example, a number of a port on a traffic module receiving data, for example, 1234, which is not specifically limited in this exemplary embodiment.
Specifically, as shown in fig. 2, the creating of the sending object of the first service module based on the topic identifier transmitted by the first service module includes steps S210 and S220, where:
in step S210, a configuration file is loaded, and a target address and a target port corresponding to the subject identifier are searched from the configuration file.
In this exemplary embodiment, each topic identifier, and a target address and a target port corresponding to each topic identifier are stored in the configuration file, for example: topic identification a 192.168.1.1: 1234, where 192.168.1.1 is the destination address and 1234 is the destination port. When the first service module transmits the subject identifier to the communication module, the communication module loads a configuration file, matches the subject identifier transmitted by the first service module with each subject identifier in the configuration file, and determines a target address and a target port corresponding to the successfully-matched subject identifier as a target address and a target port corresponding to the subject identifier transmitted by the first service module.
It should be noted that the destination address and the destination port corresponding to the subject identifier may also be directly transmitted to the communication module by the first service module through the first interface, and are not required to be obtained by the communication module by loading the configuration file.
In step S220, a sending object of the first service module is created based on the destination address and the destination port. In the exemplary embodiment, the sending object of the first business module is created based on the target address and the target port corresponding to the topic identifier transmitted by the first business module. It should be noted that the above-mentioned manner for creating the transmission object of the first module is only exemplary, and is not intended to limit the present invention.
In step S120, whether a receiving object corresponding to the subject identifier exists is searched for from the receiving container.
In the present exemplary embodiment, the receiving container here refers to a receiving container maintained in a communication module in the same process to which the first service module belongs. The receiving container stores all receiving objects in the process and the corresponding theme identifications of all the receiving objects. It should be noted that the receiving container may also include the first service module as a receiving object for the topic identification and creation transmitted by the service module for receiving data.
And matching the subject identifier transmitted by the first service module with each subject identifier in the receiving container, and searching whether a receiving object corresponding to the subject identifier transmitted by the first service module exists or not by judging whether the subject identifier matched with the subject identifier transmitted by the first service module exists or not, namely determining the receiving object corresponding to the subject identifier successfully matched with the subject identifier transmitted by the first service module as the receiving object corresponding to the subject identifier transmitted by the first service module if the subject identifier matched with the subject identifier transmitted by the first service module exists.
In step S130, if the callback function exists, the callback function of the second service module corresponding to the receiving object is registered in the sending object, so that the sending object sends the received data sent by the first service module to the second service module according to the callback function.
In this exemplary embodiment, the service module receiving the data is the second service module, and if a receiving object corresponding to the subject identifier transmitted by the first service module exists in the receiving container, it is described that the first service module and the second service module corresponding to the receiving object (i.e., the service module that needs to receive the data sent by the first service module) belong to the same process, so that this data transmission is data transmission in the process.
And when the data transmission is in-process data transmission, registering a callback function of a second service module corresponding to the receiving object to the sending object, and sending the received data sent by the first service module to the second service module by the sending object according to the callback function.
In this exemplary embodiment, if there is no receiving object corresponding to the topic identifier transmitted by the first service module in the receiving container, it is described that the first service module and a second service module corresponding to the receiving object (i.e., a service module that needs to receive data sent by the first service module) belong to different processes, that is, this data transmission is inter-process data transmission.
When the data transmission is judged to be interprocess data transmission, the first service module sends the data to a sending object, and the sending object discards the received data to the network card through a TCP/IP protocol so as to transmit the data to the service module for receiving the data through the TCP/IP protocol.
To facilitate management of the send object, the topic identification and the send object of the callback function that registers the second business module may be stored to a send container. The sending container here refers to a sending container maintained in the communication module in the process to which the first service module belongs.
Before step S120, as shown in fig. 3, the method may further include steps S310 to S330, wherein:
in step S310, the topic identifier transmitted by the second service module and the callback function of the second service module are received.
In this exemplary embodiment, the second service module is a service module that transmits the topic identifier and the callback function through the second interface, that is, the second service module transmits the topic identifier and the callback function of the second service module to the communication module through the second interface. The second service module here is a service module that receives data. The communication module comprises a plurality of interfaces, and the second interface is one of the plurality of interfaces on the communication module. The subject identification has been described above and is not described herein.
In step S320, a receiving object of the second service module is created based on the callback function.
In step S330, the subject identifier and the receiving object are stored in a receiving container.
In the present exemplary embodiment, the receiving container herein refers to a receiving container maintained in a communication module in the same process as the second service module. If the second service module and the first service module belong to the same process, the receiving container in this case is the same receiving container as the receiving container in step S120. If the second service module and the first service module do not belong to the same process, the receiving container here is a different receiving container from the receiving container in step S120.
In summary, whether a receiving object corresponding to the subject identifier exists or not is searched in the receiving container, so as to determine whether the first service module and the second service module belong to the same process, that is, whether data transmission in the process is performed or not is determined, and the determining step is simple and easy to implement; in addition, if a receiving object corresponding to the theme identifier exists, namely when the first service module and the second service module belong to the same process, the callback function of the second service module is registered to the sending object of the first service module, so that the sending object sends the received data sent by the first service module to the second service module according to the callback function.
It should be noted that, in the above process, the receiving object corresponding to the subject identifier is searched from the receiving container, so as to determine whether the data transmission is an in-process data transmission. In other exemplary embodiments of the present disclosure, it may also be determined whether the data transmission is data transmission in a process by searching for a sending object corresponding to the subject identifier from the sending container. The specific process can include: the communication module receives the theme identification transmitted by the second service module and the callback function of the second service module; creating a receiving object of the second service module based on the callback function; storing the subject identification and the receiving object into a receiving container maintained in a communication module in the same process as the second service module; the communication module receives a subject identifier transmitted by a first service module (the subject identifier is the same as the subject identifier transmitted by a second service), creates a sending object of the first service module based on the subject identifier, and stores the subject identifier and the sending object into a sending container maintained in the communication module in the same process as the first service module; and searching whether a sending object corresponding to the theme identifier transmitted by the second service module exists in a sending container maintained in the communication module in the same process as the second service module, if so, indicating that the first service module and the second service module belong to the same process, and registering a callback function of the second service module into the sending object so that the sending object sends the received data sent by the first service module to the second service module according to the callback function.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
