go线上grpc测试

proto文件：

syntax = "proto3";
option go_package = "./hellopb";

// The greeting service definition.
service Greeter {
    // Sends a greeting
    rpc SayHello (HelloRequest) returns (HelloReply) {}
  }

  // The request message containing the user's name.
  message HelloRequest {
    string name = 1;
  }

  // The response message containing the greetings
  message HelloReply {
    string message = 1;
  }

 执行转化命令，转化为go文件

服务器端代码：

package main

import (
	"context"
	"flag"
	"fmt"
	pb "gingrpc/hellopb"
	"log"
	"net"

	"google.golang.org/grpc"
)

var (
	port = flag.Int("port", 1190, "The server port")
)

type server struct {
	pb.UnimplementedGreeterServer
}

func (*server) SayHello(ctx context.Context, req *pb.HelloRequest) (*pb.HelloReply, error) {
	fmt.Println(req.GetName())
	return &pb.HelloReply{Message: "hello " + req.GetName()}, nil
}

func main() {
	flag.Parse()
	lis, err := net.Listen("tcp", fmt.Sprintf("0.0.0.0:%d", *port))
	if err != nil {
		log.Fatalf("failed to listen: %v", err)
	}

	s := grpc.NewServer()
	pb.RegisterGreeterServer(s, &server{})
	log.Printf("server listening at %v", lis.Addr())
	if err := s.Serve(lis); err != nil {
		log.Fatalf("failed to serve: %v", err)
	}
}

 客户端代码：

package main

import (
	"context"
	"flag"
	"log"
	"time"

	pb "gingrpc/hellopb"

	"google.golang.org/grpc"
	"google.golang.org/grpc/credentials/insecure"
)

const (
	defaultName = "world"
)
//*****为放服务端代码的服务器ip
var (
	addr = flag.String("addr", "******:1190", "the address to connect to")
	name = flag.String("name", defaultName, "Name to greet")
)

func main() {
	flag.Parse()
	// Set up a connection to the server.
	conn, err := grpc.Dial(*addr, grpc.WithTransportCredentials(insecure.NewCredentials()))
	if err != nil {
		log.Fatalf("did not connect: %v", err)
	}
	defer conn.Close()
	c := pb.NewGreeterClient(conn)

	// Contact the server and print out its response.
	ctx, cancel := context.WithTimeout(context.Background(), time.Second)
	defer cancel()
	r, err := c.SayHello(ctx, &pb.HelloRequest{Name: *name})
	if err != nil {
		log.Fatalf("could not greet: %v", err)
	}
	log.Printf("Greeting: %s", r.GetMessage())
}

 对服务器端代码进行跨平台编译win对linux

进入到服务端代码所在目录下执行

SET CGO_ENABLED=0

set GOARCH=amd64

set GOOS=linux

go build main.go

 把生成的文件放到服务器上运行

 成功运行并放开对应端口

 服务端项目运行成功。

执行本地客户端

 访问成功

服务端日志：

 速度上看，很不理想，没处理任何curd操作，要5秒才能返回数据
