Go语言实现服务器和客户端比较简单
服务器：
listen
accept
recv

客户端
dial
write

1.server.go

package mainimport ("log""net""os"
)func recvMessage(client net.Conn) error {var message []bytemessage = make([]byte, 1024)for {len, _ := client.Read(message)if len > 0 {log.Println(message[0:len])}}return nil
}func main() {server, err := net.Listen("tcp", "localhost:9700")if err != nil {log.Fatal("start server failed!\n")os.Exit(1)}defer server.Close()log.Println("server is running...")for {client, err := server.Accept()if err != nil {log.Fatal("Accept error\n")continue}log.Println("the client is connectted...")go recvMessage(client)}
}

2.client.go

package mainimport ("log""net""os"
)func main() {client, err := net.Dial("tcp", "localhost:9700")if err != nil {log.Fatal("Client is dailing failed!")os.Exit(1)}client.Write([]byte("i am client"))client.Close()
}
