GRPC安装

GRPC安装

  1. 在环境变量配置你的go_path/bin

  2. 下载protoc,解压缩到go_path/bin

  3. 运行命令

    go get google.golang.org/protobuf/cmd/protoc-gen-go 
    go get google.golang.org/grpc/cmd/protoc-gen-go-grpc
    
  4. 写个helloworld.pb文件

    syntax = "proto3";
    
    option go_package = "google.golang.org/grpc/examples/helloworld/helloworld";
    option java_multiple_files = true;
    option java_package = "io.grpc.examples.helloworld";
    option java_outer_classname = "HelloWorldProto";
    
    package helloworld;
    
    // The greeting service definition.
    service Greeter {
      // Sends a greeting
      rpc SayHello (HelloRequest) returns (HelloReply) {}
    }
    
    // The request message containing the user's name.
    message HelloRequest {
      string name = 1;
    }
    
    // The response message containing the greetings
    message HelloReply {
      string message = 1;
    }
    
  5. 编译(注意windows为一行,并且去掉下划线)

    protoc --go_out=. --go_opt=paths=source_relative \
        --go-grpc_out=. --go-grpc_opt=paths=source_relative \
        helloworld/helloworld.proto
