python_day8 socket 网络编程 多客户端，单服务端，单线程 不挂机处理

服务端：

import socket

server=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
server.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
server.bind(('127.0.0.1',80))
server.listen(5)
while True:
    conn,address=server.accept()
    while True:
        try:
            data=conn.recv(1024)
            if not data:break
            print(data)
            conn.send(data.upper())
        except Exception:
            break
    conn.close()
server.close()




客户端1：

import socket
client=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client.connect(('127.0.0.1',80))

while True:
    inp=input('>>:')
    if not inp:continue
    client.send(inp.encode('utf-8'))
    data=client.recv(1024)
    print(data)
client.close()




客户端2：

import socket
client=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client.connect(('127.0.0.1',80))

while True:
    inp=input('>>:')
    if not inp:continue
    client.send(inp.encode('utf-8'))
    data=client.recv(1024)
    print(data)
client.close()
