C++ Version: https://github.com/chai2010/protorpc.cxx
Talks: Go/C++语言Protobuf-RPC简介
Intasll protorpc package:
go get github.com/chai2010/protorpcgo run hello.go
Install protoc-gen-go plugin:
- instal
protocat first: http://github.com/google/protobuf/releases go get github.com/chai2010/protorpc/protoc-gen-gogo generate github.com/chai2010/protorpc/internal/service.pbgo test github.com/chai2010/protorpc/internal/service.pb
First, create echo.proto:
package service;
message EchoRequest {
optional string msg = 1;
}
message EchoResponse {
optional string msg = 1;
}
service EchoService {
rpc Echo (EchoRequest) returns (EchoResponse);
rpc EchoTwice (EchoRequest) returns (EchoResponse);
}Second, generate echo.pb.go
from echo.proto (we can use go generate to invoke this command, see proto.go).
protoc --go_out=plugins=protorpc:. echo.proto
Now, we can use the stub code like this:
package main
import (
"fmt"
"log"
service "github.com/chai2010/protorpc/internal/service.pb"
"github.com/golang/protobuf/proto"
)
type Echo int
func (t *Echo) Echo(args *service.EchoRequest, reply *service.EchoResponse) error {
reply.Msg = proto.String(args.GetMsg())
return nil
}
func (t *Echo) EchoTwice(args *service.EchoRequest, reply *service.EchoResponse) error {
reply.Msg = proto.String(args.GetMsg() + args.GetMsg())
return nil
}
func init() {
go service.ListenAndServeEchoService("tcp", `127.0.0.1:9527`, new(Echo))
}
func main() {
echoClient, err := service.DialEchoService("tcp", `127.0.0.1:9527`)
if err != nil {
log.Fatalf("service.DialEchoService: %v", err)
}
defer echoClient.Close()
args := &service.EchoRequest{Msg: proto.String("你好, 世界!")}
reply, err := echoClient.EchoTwice(args)
if err != nil {
log.Fatalf("echoClient.EchoTwice: %v", err)
}
fmt.Println(reply.GetMsg())
// or use normal client
client, err := protorpc.Dial("tcp", `127.0.0.1:9527`)
if err != nil {
log.Fatalf("protorpc.Dial: %v", err)
}
defer client.Close()
echoClient1 := &service.EchoServiceClient{client}
echoClient2 := &service.EchoServiceClient{client}
reply, err = echoClient1.EchoTwice(args)
reply, err = echoClient2.EchoTwice(args)
_, _ = reply, err
// Output:
// 你好, 世界!你好, 世界!
