一. 运行代码
client.go
package main
import (
"context"
"fmt"
"google.golang.org/grpc"
pb "hello-grpc/proto/grpc_hello_service"
"log"
)
func main() {
conn ,err := grpc.Dial("localhost:1234",grpc.WithInsecure())
if err != nil {
log.Fatal(err)
}
defer conn.Close()
client := pb.NewHelloServiceClient(conn)
reply,err := client.Hello(context.Background(), &pb.String{Value:"hello"})
if err != nil {
log.Fatal(err)
}
fmt.Println(reply.GetValue())
}
server.go:
package main
import (
"google.golang.org/grpc"
"log"
"net"
pb "hello-grpc/proto/grpc_hello_service"
"hello-grpc/service"
)
func main() {
grpcServer := grpc.NewServer()
pb.RegisterHelloServiceServer(grpcServer, &service.HelloServiceImpl{})
lis, err := net.Listen("tcp","localhost:1234")
if err != nil {
log.Fatal(err)
}
grpcServer.Serve(lis)
}
二. 运行结果
