基于SOCKET写一个web应用

py文件

import socket

def server_run():
    soc = socket.socket()
    soc.bind(('127.0.0.1', 8008))
    soc.listen(5)
    while True:
        conn, addr = soc.accept()
        recv_data = conn.recv(1024)
        print(recv_data)
        # 1 直接在send里写，发送给客户端
        # conn.send(b'HTTP/1.1 200 OK\r\n\r\n
hello web
')
        #2 打开一个html文件，发送给客户端
        # with open('index.html','r',encoding='utf-8') as f:
        #     data=f.read()
        # conn.send(('HTTP/1.1 200 OK\r\n\r\n%s'%data).encode('utf-8'))
        # 3 动态网页，字符串替换
        import time
        now=time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
        print(now)
        with open('index.html','r',encoding='utf-8') as f:
            data=f.read()
        data=data.replace('@@@',now)
        conn.send(('HTTP/1.1 200 OK\r\n\r\n%s'%data).encode('utf-8'))
        conn.close()

if __name__ == '__main__':
    server_run()
