protobuf installation

Github: https://github.com/protocolbuffers/protobuf/releases

First download protoc, then protoc-3.19.4-win64.zip/bin/protoc.exeunzip it GOPATH/bin
and GOPATH/binadd it to the system Path

Install the protogo compiler plugin

go install google.golang.org/protobuf/cmd/[email protected]
go install google.golang.org/grpc/cmd/[email protected]

Create a new grpc.proto file

syntax = "proto3";

package pb; 
option go_package="./;pb";   // pb是生成.go文件的package名

service GRPC{
    
    
  rpc Ping(ping) returns(pong);
}

message ping {
    
    
  string msg = 1;
}

message pong{
    
    
  string  msg = 1;
}

4. Compile the .proto file

cmd run:

protoc --go_out=. --go_opt=paths=source_relative  --go-grpc_out=. --go-grpc_opt=paths=source_relative  grpc.proto

The first step to generate the protobuf file is complete

protobuf usage

syntax = "proto3";

package xxxx;

message Xxx{
    
    
  string name = 1;
  int32 age = 2;
  bool sex = 3;
  repeated string ss = 4;
  map<string,string> testmap = 5;
}

service XXXService {
    
    
  rpc XXXX(参数) returns (参数);
  rpc XXXX(stream 参数) returns (参数); // 流
}
