python sockert服务端+socket客户端

[python]代码库

# sockert服务端

import socket

# 客户端
# 声明协议类型,同时生成socket对象
client = socket.socket()
#
client.connect(('localhost', 9999))
# python3 接收字节流数据
while True:
    msg = input('>>:').strip()
    if len(msg) == 0:  # 输入不能为空
        continue
    client.send(msg.encode('utf-8'))
    data = client.recv(1024)  # 1024字节的数据
    print(data)
    print(data.decode())





# socket客户端

# -*- coding: UTF-8 -*-
import socket

# 声明协议类型
server = socket.socket()
# 绑定本地网卡（多网卡选择），端口
server.bind(('localhost', 9999))
# 监听端口
server.listen(5)  # 监听
while True:
    conn, address = server.accept()
    print("进入等待时间....")
    while True:
        print("收到连接....")
        # 接收数据
        data_server = conn.recv(1024)
        if not data_server:  # 这里判断客户端断开的情况，不控制会无限循环
            print('client is lost...')
            break
        print('receive:', data_server.decode())
        # 返回一个值
        conn.send(data_server)
