Node.js-based RPC synchronous communication method and equipment

Abstract

The invention discloses a Node.js-based RPC synchronous communication method and device, the method is applied to a local end, the local end is connected with a remote end through a TCP, and the method comprises the following steps: sending a request of a remote call function to the remote end, and after the request is sent, carrying out loop detection in a cache by using a c++-based Application.DoEvent; and if the response packet is detected in the cache, obtaining a response value corresponding to the response packet, wherein the response packet is generated after the remote end processes the request and is sent to the cache by the remote end. According to the method, the Application.DoEvent event processing interface operation of the c++ layer is cyclically called through the local end, the function of the calling module and the function of the called module do not need to be changed into an asynchronous function, the complexity of remote calling is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a Node.js-based RPC synchronous communication method and device. Background technique [0002] RPC (Remote Procedure Call, remote procedure call), a simple understanding is that a node requests a service provided by another node. [0003] At present, RPC synchronous communication based on Node.js (a JavaScript operating environment based on Chrome V8 engine) uses async / await (asynchronous / wait) and other similar methods to simulate synchronous communication, that is, the client or server initiates a request, waits for the other party to process and Return the result synchronously. However, in the actual development process, sometimes it is necessary to change the local module to a remote call. The current method used is to use RPC remote call. [0004] When the locally dependent module is changed to a remote module, if a synchronous call is required (i.e. to achieve ...

AI Technical Summary

Problems solved by technology

This will lead to the need to change the method called by the module interface, especially when reusing the local synchronous module, if the local module called by a certain function is changed to a remote module, a large number of functions related to this function need to be changed to asynchronous functions, adding The complexity of remote calls, and it is easy to ignore the synchronization wait in the change and cause synchronization problems
