golang protobuf 安装使用

1. 安装protoc

   git clone https://github.com/google/protobuf.git

   cd protobuf

   sudo apt-get install autoconf automake libtool curl make g++ unzip

   ./autogen.sh

   ./configure

   make

   make check

   sudo make install

   sudo ldconfig # refresh shared library cache.

2. 安装编译器的golang插件

   //protoc-gen-go默认安装在:$GOBIN或$GOPATH/bin,方便protoc通过$PATH查找protoc-gen-go

   //$GOPATH=/data/golang

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

3. protobuf使用

   mkdir -p /data/golang/shared/proto

   cd /data/golang/shared/proto

   编辑test.proto,用于网络协议数据组织

   test.proto:

   syntax = "proto3";

   package tutorial;

   message Person { string name = 1; int32 id = 2; // Unique ID number for this person. string email = 3;

   enum PhoneType { MOBILE = 0; HOME = 1; WORK = 2; }

   message PhoneNumber { string number = 1; PhoneType type = 2; }

   repeated PhoneNumber phones = 4; }

   // Our address book file is just one of these. message AddressBook { repeated Person people = 1; }

   protoc --go_out=/data/golang/src/test/proto-test test.proto

   建立工程,引入产生golang代码的网络协议(test.pb.go).

例子:

package main

import (

"fmt"

im "test/proto-test"

proto "github.com/golang/protobuf/proto"

)

func main() {

/*  
var user *im.Person = &im.Person{
    Name: *proto.String("jack"),Id: *proto.Int32(100),Email: *proto.String("365@163.com"),};  
*/  
var user *im.Person = &im.Person{
    Name: "meng",Id: 100,Email: "123@163.com",};  
//编码
fmt.Println(user.String());
buffer,_ := proto.Marshal(user);
fmt.Println(buffer);

//解码
var copy_user = &im.Person{};
proto.Unmarshal(buffer,copy_user);
fmt.Printf("copy_user=%vn",copy_user);

}
