python(socket通信实例单用户可持续通信)

#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',6960))

while True:
    msg = input(">>:").strip()
    if len(msg) == 0:continue
    client.send(msg.encode("utf-8"))
    data = client.recv(10240)
    print("recv:",data.decode())

client.close()

 

#服务器端

import socket
server = socket.socket()
server.bind(('localhost',6960)) #绑定要监听端口
server.listen(5) #监听

print("我要开始等电话了")
while True:
    conn, addr = server.accept()  # 等电话打进来接受数据
    # 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)
    print("电话来了")
    count = 0
    while True:
        data = conn.recv(1024) #接受数据
        print("recv:",data)  #打印接收的数据
        if not data:
            print("client has lost...")
            break
        conn.send(data.upper())  #把数据变大写转回
        count+=1
        if count >10:break

server.close()
