Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to a remote procedure call method, which is applied to a server and comprises the following steps: uniformly receiving a calling request sent by a client through a preset interface; routing the calling request to a target micro-service process corresponding to the calling request according to the calling request; and processing the calling request through the target micro-service process to obtain a calling result, and sending the calling result to the client through a preset interface. And receiving the call request sent by the client through a uniform call interface, and routing the call request to the corresponding micro-service process, so that the sending object of the call request is more definite. The implementation details of the remote procedure call method according to this embodiment are described in detail below, and the following description is only provided for the convenience of understanding, and is not necessary for implementing this embodiment. The specific flow is shown in figure 1.
Step 101, uniformly receiving a call request sent by a client through a preset interface. Specifically, a functional interface of the server is optimized, and a fixed interface is set to uniformly receive a call request of the client. For example, calling requests sent by a first terminal, a second terminal, a third terminal and the like of a client are all received by a preset interface of a server, the server manages the calling requests received by the preset interface, a module capable of managing the calling requests by the server is named as a connector module in practical application, and the calling requests received by the server are all received by the connector module.
And 102, routing the calling request to a target micro-service process corresponding to the calling request according to the calling request. Specifically, the service end receives the call request including the service name, the calling method name, and the session type. The service name is used for determining the micro-service module corresponding to the calling request; the calling method names correspond to the calling interfaces and are used for determining functions which can be realized in the micro-service module; the session type includes a short connection request type and a long connection request type, and is used for distinguishing the session type of the call request.
The following describes a call request of the short connection request type and a call request of the long connection request type.
When the session type of the call request is a short connection request type, the short connection request is a request for list data, a request for attendance rules and the like, the connector module routes the call request to the micro-service module corresponding to the call request according to the service name and the calling method name in the call request, and if more than one micro-service module meeting the calling conditions of the call request, one micro-service module with the lowest utilization rate is selected from the calling conditions meeting the call request to process the call request, so that the call result is obtained more efficiently. And when the micro-service module processes the call request, the micro-service module analyzes the message in the call request, and returns the service data called by the client to the connector module according to the analyzed call request to complete the processing of the call request. When the connector module sends a call request to a target microservice process, if the sending fails due to conditions such as overtime, network disconnection and the like, the call request is added into a queue with failed sending, and the call request is automatically retransmitted by a background, so that the call request is ensured to be replied.
When the session type of the call request is a long connection request type, the long connection request is a request such as login, logout, automatic login and the like, the connector module establishes a bidirectional channel between the server and the client, and transmits the long connection request and a call result aiming at the request through the bidirectional channel. After the bidirectional channel is established, whether the connection of the channel is normal or not needs to be detected, and a heartbeat mechanism can be adopted to detect the connection condition of the channel. In addition, when the call request is transmitted by using the bidirectional channel, the user permission of the call request needs to be judged by using the token, and if the terminal user sending the call request does not have the use permission of the bidirectional channel, the call request is refused to pass through the bidirectional channel. And refreshing the token after the token fails, so that the problem that the token fails to cause interface error report is avoided.
And 103, processing the calling request through the target micro-service process to obtain a calling result.
And step 104, sending the calling result to the client through a preset interface. Specifically, after the micro service module obtains the call result, the micro service module may be returned to the connector module, and the connector module sends the call result to the client.
Compared with the prior art, the interface calling is transparent, the server receives the calling request sent by the client side through the fixed interface in a unified mode, the received calling request is routed to the target micro-service process for processing the calling request, the target micro-service process processes and replies the calling request, the obtained calling result is returned to the client side, and the interface for returning the calling result is the same as the interface for receiving the calling request sent by the client side. By the method, the interface can be definitely called, and the client directly sends the calling request to the fixed calling interface, so that the sending object of the calling request is more definite. On the other hand, the receiving and processing of the call request correspond to different processes respectively, and when the micro service process is used for service change, the receiving of the call request is not influenced, and the normal work of other micro service processes is not influenced, so that the service does not need to be interrupted, and the normal response of the call request is ensured.
The second embodiment of the invention relates to a remote procedure call method, which is applied to a client and comprises the following steps: defining a calling request; wherein, the calling request at least comprises: business data and service names; sending the calling request to a preset interface of the server, so that the server can receive the calling request through the preset interface in a unified manner and process the calling request; and when the server returns the calling result, receiving the calling result. The implementation details of the remote procedure call method according to this embodiment are described in detail below, and the following description is only provided for the convenience of understanding, and is not necessary for implementing this embodiment. The specific flow is shown in fig. 2.
In the embodiment, the client defines the call request, and sends the defined call request to the unified call interface of the server, so that the sending object of the call request is clarified. The ProtoBuf protocol is utilized when the call request is defined, the performance of data serialization is improved, when the call request is sent to a preset interface of a server side, transmission is carried out based on the HTTP/2 protocol, header information of transmission data can be compressed, and the header information of the protocol is smaller, so that the time and the data volume of the transmission data are reduced, and the call efficiency of a client side is improved.
