Python使用socket模块实现简单tcp通信

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

运行方法：

一个利用windows的cmd，直接输入命令：python server.py运行服务器

一个利用pycharm直接运行client.py
