go-grpc 使用

1. 安裝

$ go get -u google.golang.org/grpc

因爲牆緣由能夠從golang中國 第三方包下載

https://golangtc.com/download/package

 

將文件下載下來拷貝到到對應文件夾下面

 

2.編譯文件

protoc --go_out=plugins=grpc:. *.proto

 

3.使用

 

服務端

 

svr := grpc.NewServer()

inf.RegisterUserDataServer(svr, &UserData{})

 

type UserData struct{}

func (d *UserData) GetUser(ctx context.Context, request *inf.UserReq) (response *inf.UserRsp, err error) {

response = &inf.UserRsp{

Name: strconv.Itoa(int(request.UserId)) + ":tip",

}

return response, err

}

 

客戶端

conn, err := grpc.Dial(fmt.Sprintf("127.0.0.1:%s", port), grpc.WithInsecure())

cli := inf.NewUserDataClient(conn)

getUser(cli)

 

func getUser(cli inf.UserDataClient) {

iRand := rand.Intn(100)

req := inf.UserReq{

UserId: int32(iRand),

}

rsp, err := cli.GetUser(context.Background(), &req)

if err != nil {

fmt.Println(err)

return

}

log.Printf("response:%v", rsp)

}
