Python网络编程基础-简单Socket实例


import socket
server = socket.socket()
server.bind(('localhost', 5555))#绑定端口
server.listen()#监听
print("开始等电话了")
conn, addr = server.accept()
#conn就是客户端连过来的时候在服务器端为其生成的一个连接实例
print(conn, addr)
print("电话来了")
data = conn.recv(1024)
print("recv:", data)
conn.send(data.upper())
server.close()

Client：

import socket
client = socket.socket()
client.connect(('localhost', 5555))
client.send(b"Hello,Hunter")
date = client.recv(1024)
print("recv:", date)
client.close()
