python网络编程之读取网站根目录实例

本文实例讲述了python网络编程之读取网站根目录的方法，分享给大家供大家参考。

具体实现方法如下：

    import socket, sys 

    port = 70 
    host = "quux.org" 
    filename = "//" 

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
    s.connect((host, port)) 
    s.sendall(filename+"\r\n") 

    while(1): 
      buf = s.recv(2048) 
      if not buf: 
        break 
      sys.stdout.write(buf) 

本文实例运行环境为Python2.7.6

该实例会返回quux.org的根目录的列表

返回结果如下：

    iWelcome to gopher at quux.org! fake (NULL) 0
