Python使用socket模块实现简单tcp通信_Python

正文开始：

服务器端代码：

				?

									# 再来简单的测试，这个是服务器端

									import socket

									import sys

									BUF_SIZE = 1024

									ip_port = (r"127.0.0.1", 11552)

									my_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 先拿到套接字,指定个ipv4以及流式数据包

									my_socket.bind(ip_port) # 绑定

									my_socket.listen(2)

									# 循环等待客户端连接

									while True:

									  print("waiting for client..")

									  conn, address = my_socket.accept()

									  print("connect from .." + str(address))

									  # 循环接受

									  while True:

									    ret = conn.recv(BUF_SIZE)

									    print("server receive data:" + str(ret))

									    if "END" in str(ret):

									      print("clent's gonna be offline.")

									      conn.send(bytes("BYE", encoding="utf-8"))

									      my_socket.close()

									      sys.exit()

									    else:

									      conn.send(bytes("server copy", encoding="utf-8"))

客户端代码：

				?

									# 这个是客户端

									import socket

									BUF_SIZE = 1024

									ip_port = (r"127.0.0.1", 11552)

									my_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

									my_socket.connect(ip_port)

									while True:

									  data = input(">>>")

									  my_socket.send(bytes(data, encoding="utf-8"))

									  recieve_data = my_socket.recv(BUF_SIZE)

									  print("client receive data = " + str(recieve_data))

									  if "BYE" in str(recieve_data):

									    print("server disconnect!")

									    break
