rpc in the Go language is a remote procedure call protocol used to implement inter-process communication between different computers. rpc is the abbreviation of remote procedure call, which allows one computer program to call a program on another computer without knowing the underlying network details, thus facilitating inter-program communication.

rpc in Go language provides built-in support in the standard library, including client and server parts, which can call each other. rpc implements inter-process communication through network protocols, such as TCP or HTTP. It can encapsulate function or method calls into simple network protocols and enable them to be transmitted and executed between different computers. In the Go language, rpc can support asynchronous calls, thus improving the performance of the entire program.

The basic principle of rpc is that when calling a remote function or method, the local client sends a function call request to the remote server. After receiving the request, the remote server implements the specific function through local code, and after completion Return results. In this process, rpc communication can support complex interactions such as formal parameters, return value calls, and parameter serialization to achieve inter-process communication.

In the Go language, the use of rpc is very simple. First, define a type on the server side, which contains methods and functions that need to be called remotely. Then on the client side, connect to the server side through the rpc.Dial method to achieve communication between client and server. Finally, the client uses the Call method to remotely call the server method to start the remote procedure call process.

The use of rpc in Go language has the following characteristics:

  1. Easy to use: Built-in support is provided in the standard library, which is simple and easy to use;
  2. Support Different network protocols, such as TCP, HTTP, etc.;
  3. supports asynchronous calls to improve program performance;
  4. supports a large number of concurrent connections, which can improve system throughput.

In short, in the Go language, rpc is a very convenient and efficient method to achieve inter-process communication. It also has good portability and scalability. More programmers are starting to Use rpc for program development, thereby improving program performance and maintainability.
