记录下protoc生成go文件后，使用grpc调用的过程

• grpc安装

 go get -u -v google.golang.org/grpc 

• server.go

package main

import (
	"context"
	"fmt"
	"google.golang.org/grpc"
	"net"
	"rpc/student"
	"strconv"
)

type Stu struct {

}

func (s Stu) GetInfo (ctx context.Context, req *student.StuReq) (*student.Student, error){

	student := student.Student{
		Score: 10,
		P:     &student.Person{
			Name: "hello"+ strconv.Itoa(int(req.Id)),
			Sex:  0,
		},
		Like:  []string{
			"football",
			"sport",
		},
	}

	return &student,nil
}

func main(){

	grpcServer := grpc.NewServer()

	student.RegisterStuServiceServer(grpcServer,new(Stu))

	listen,err := net.Listen("tcp","127.0.0.1:8082")
	if err != nil{
		fmt.Println(err)
	}
	defer listen.Close()

	grpcServer.Serve(listen)

}

• client.go

package main

import (
	"context"
	"fmt"
	"google.golang.org/grpc"
	"rpc/student"
)

func main(){

	client,err := grpc.Dial("127.0.0.1:8082",grpc.WithInsecure())
	if err != nil{
		fmt.Println(err)
	}
	defer client.Close()

	stuClient := student.NewStuServiceClient(client)

	stuReq := student.StuReq{Id:1}

	stu,err := stuClient.GetInfo(context.TODO(),&stuReq)
	if err != nil{
		fmt.Println(err)
	}

	fmt.Println(stu)
}
