Use of Protocolbuff in Golang

This is a creation in Article, where the information may have evolved or changed.

Protocolbuff is an open-source serialization protocol from Google that almost supports all the mainstream languages on the market. The network transport protocol used as a server or server or a client-server is no more appropriate. Simply write a demo.
Project structure:

ProtocolBuff    ----Makefile    ----src           ----github.com/golang/protobuf           ----main           ----protocol

Configuration Protocol:
Protocol/protocol.proto

package protocol;enum ItemType{        USERITEM  = 1;        EQUIPMENT = 2;};message ItemInfo{        optional int32 ID = 1;        optional int32 Type = 2;        optional string Name = 3;        optional int32 Amount = 4;};

Executes PROTOC--go_out=./Protocol.proto automatically generates PROTOCOL.PB.GO, generating the directory as the current directory. PROTOC supports the generation of multiple languages, with protoc-h viewing.

Main/main.go

package mainimport (    "github.com/golang/protobuf/proto"    "fmt"    "protocol")func main() {    item := protocol.ItemInfo{        ID : proto.Int32(10),        Type : proto.Int32(1),        Name : proto.String("item_0"),        Amount: proto.Int32(99),    }    data := EncodeMsg(&item)//封包    fmt.Printf("Encode Data %v \n", data)    res := DecodeMsg(data)//解包    fmt.Printf("Decode Data %v \n", res.String())}func EncodeMsg(pb proto.Message) []byte{    data, err := proto.Marshal(pb)    if err != nil{        fmt.Errorf("%v \n",err.Error())    }    return data}func DecodeMsg(data []byte)  (result protocol.ItemInfo){    proto.Unmarshal(data, &result)    return}

Makefile

GOPATH := $(shell pwd)all:        GOPATH=${GOPATH} go install main

After make, the executable file is generated in the Bin directory, main, and the results are executed:
Encode Data [8 10 16 1 26 6 105 116 101 109 95 48 32 99]
Decode Data id:10 type:1 Name: "Item_0" amount:99
