知识点：Web编程，抓包，模拟post请求

参考代码：

#!/usr/bin/env python
# encoding: utf-8

import requests
import sys
import re
reload(sys)

sys.setdefaultencoding("utf-8")

password = "1"
payload = {
    "csrfmiddlewaretoken": "2tPnnkChyTMW4o36jheDklAvUyPX1nhs",
    "username": "a",
    "password": password
}

for i in range(31):
	payload["password"] = str(i)   #不能直接赋值password，这样无法修改字典中的password值，必须要通过字典访问
	resp = requests.post("http://www.heibanke.com/lesson/crawler_ex01/", data=payload)
	text = unicode(resp.content).encode("utf8")
	if text.find(u"错误".decode("utf8")) == -1:
		print "[+] FOUND: "+ payload["password"]
		break
	else:
		print payload["password"]
