群上闲聊，说道自己封装了一个 python 的 http head 工具

#!/usr/bin/env python

from socket import *

while True:
    HOST = raw_input('> ')
    if not HOST:
        break
    tcpCliSock = socket(AF_INET, SOCK_STREAM)
    PORT = 80
    BUFSIZ = 1024
    ADDR = (HOST, PORT)
    tcpCliSock.connect(ADDR)
    data = "HEAD / HTTP/1.1rnHost: %srnrn" % HOST
    tcpCliSock.send(data)
    data = tcpCliSock.recv(BUFSIZ)
    if not data:
        break
    print data
tcpCliSock.close()

输入输出
