socket.md

使用PY实现

服务端

import socket导入包

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:使用with as语句会在结束代码块的时候, 自动调用.close方法关闭

• socket.AF_INET 表示 IPv4 地址家族
• socket.SOCK_STREAM 表示流式套接字

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
    s.bind(('0.0.0.0', 8888))
    s.listen()

• 注意, bind方法只能传入一个

    with conn:
        print('Connected by', addr)
        while True:
            data = conn.recv(1024)
            if not data:
                break
            conn.sendall(data) #回传

接受处理数据

客户端

import socket

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
    s.connect(('localhost', 8888))
    s.sendall(b'Hello, world')
    data = s.recv(1024)
    print('Received', repr(data))
