RPC Communication programming

Using RPC programming is one of the strongest and most efficient ways to reliably communicate between client and server entities. It provides the foundation for almost any application running in a distributed computing environment.

What is RPC?

The full name of RPC is Remote Procedure call, which is an inter-process communication method. It allows a program to call a procedure or function of another address space (usually on another machine on a shared network) without the programmer explicitly coding the details of this remote invocation. That is, programmers, whether they call local or remote, write essentially the same calling code.

The primary function of RPC is to make it easier to build distributed computing (applications) without losing the semantic simplicity of local calls when providing powerful remote invocation capabilities. In layman's terms, it is common for programmers to be familiar with local process calls, so we make RPC as a local call, which is much easier to accept and use without obstacles.

Learning is still shallow, first introduce the RPC usage scenarios I have encountered.

In the game server design, the recharge login process can be composed of the following steps. First component: Game client Gameapp game Server Gameserver top-up server Cashserver platform client Sdkapp platform Server Sdkserver will send a request to Sdkserver for authentication upon login request. During the period through the recharge server forwarding to Sdkserver authentication, the general Sdkserver receive HTTP requests, return HTTP messages, when the login request sent to the recharge server, you can use RPC, define the RPC protocol. Similar to the application order RPC transfer order RPC query user ID RPC is used in the process of using the same as the local method, does not involve network operations, simple and convenient, so that complex network operations encapsulated in the bottom.
