go语言使用proto

安装

go get -d -u github.com/golang/protobuf/protoc-gen-go
go install github.com/golang/protobuf/protoc-gen-go

定义proto文件

syntax = "proto3";

package model;

message SayParam {
    string msg = 1;
}

message Pair {
    int32 key = 1;
    string values = 2;
}

message SayResponse {
    string msg = 1;
    // 数组
    repeated string values = 2;
    // map
    map<string, Pair> header = 3;
    RespType type = 4;
}

enum RespType {
    NONE = 0;
    ASCEND = 1;
    DESCEND = 2;
}

// 服务接口
service Say {
    rpc Hello(SayParam) returns (SayResponse) {}
}

生成 go 代码

protoc --proto_path=/home/www/go/src --go_out=. /home/www/go/src/protoTest/common.proto
proto_path

--proto_path=PATH Specify the directory in which to search for  imports. May be specified multiple times;  directories will be searched in order. If not  given, the current working directory is used.  If not found in any of the these directories,  the --descriptor_set_in descriptors will be  checked for required proto file.

• 表示导入包的寻找路径
• 命令的最后参数是proto文件路径
