基于TCP协议编写的套接字

一：套接字通信(socket)模块

  1.1：服务端
  import socket
  #1、买手机
  phone = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

  #2、绑定电话卡
  phone.bind(("127.0.0.1",8080))        #ip地址和端口号

  #3、开机
  phone.listen(5)   #小整数池设为5

  #4、接收链接请求
  while True:
      conn,client_addr = phone.accept()
      # print(client_addr)

      #5、接发消息
      while True:
          data = conn.recv(1024)
          print(data.decode("utf-8"))
          msg = input(">>>>:")
          conn.send(msg.encode("utf_8"))

      #6、挂电话
      conn.close()

  #7、关机
  phone.close()

  1.2：客户端
  import socket
  #1、买手机
  phone = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

  #2、打电话
  phone.connect(("127.0.0.1",8080))

  #3、发\收数据
  while True:
      msg = input(">>>>>: ").strip()
      phone.send(msg.encode("utf-8"))
      data = phone.recv(1024)
      print(data.decode("utf-8"))

  #4、关机
  phone.close()
