python socket了解使用

#服务器端

import socket

server = socket.socket()
server.bind(('localhost',6969))#绑定要监听端口

server.listen()#监听
conn, addr = server.accept() # 等电话打进来
# conn就是客户端连过来而在服务器端为其生成的一个连接实例
print(conn, addr)
while True:
print('电话来了')
data=conn.recv(1024)
print('recv:',data)
conn.send(data.upper())

server.close()


#客户端
import socket

client= socket.socket()#声明socket类型,同时生成socket连接对象
client.connect(('localhost',6969))

while True:
msg = input(">>:").strip()
if len(msg)== 0:continue
client.send(msg.encode("UTF-8"))
data= client.recv(1024)
print('recv:',data.decode())

client.close()
