GRPC初探--简单客户端，服务端编写

服务端

package main

import (
    pb "NewGrpc/proto/github.com/lkpalu/grpc-go/proto"
    "context"
    "google.golang.org/grpc"
    "log"
    "net"
)

type newServer struct {
    pb.UnimplementedNewServer
}

func (s *newServer) Hello(ctx context.Context, re *pb.Request) (*pb.Response, error) {
    return &pb.Response{
       Messages: "Hello World" + re.Messages,
    }, nil
}
func main() {
    //n := newServer{}
    grpcServer := grpc.NewServer()
    pb.RegisterNewServer(grpcServer, &newServer{})
    lis, err := net.Listen("tcp", ":8080")
    if err != nil {
       log.Fatalf("failed to listen: %v", err)
    }
    err = grpcServer.Serve(lis)
    if err != nil {
       log.Fatalf("failed to serve: %v", err)
    }
}

服务端实现定义的接口即可

客户端

package main

import (
    pb "NewGrpc/proto/github.com/lkpalu/grpc-go/proto"
    "context"
    "fmt"
    "google.golang.org/grpc"
    "google.golang.org/grpc/credentials/insecure"
)

func main() {
    m := pb.Request{
       Messages: "lkpalu",
    }
    conn, err := grpc.NewClient("localhost:8080", grpc.WithTransportCredentials(insecure.NewCredentials()))
    if err != nil {
       panic(err)
    }
    defer conn.Close()
    client := pb.NewNewClient(conn)
    resp, err := client.Hello(context.Background(), &m)
    fmt.Println(resp.Messages)
}

客户端直接调用即可
