这一关是猜密码

挑战难度:★★☆☆☆☆☆☆☆☆

难度不大，穷举：

上代码：

#coding:utf-8
    import requests
    from bs4 import BeautifulSoup as bf
    import re
    import time
    header = {
    'Host':'www.heibanke.com',
    'User-Agent':'Mozilla/5.0(WindowsNT10.0;WOW64;rv:67.0)Gecko/20100101Firefox/67.0',
    'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
    'Accept-Language':'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',
    'Accept-Encoding':'gzip,deflate',
    'Referer':'http://www.heibanke.com/lesson/crawler_ex01/',
    'Content-Type':'application/x-www-form-urlencoded',
    'Content-Length':'84',
    'Connection':'keep-alive',
    'Cookie':'csrftoken=fOg49OcOmWf2uqsuQMxY6yVvE6YHLnE9;Hm_lvt_74e694103cf02b31b28db0a346da0b6b=1559235324,1559235334,1559315801,1559790366;Hm_lpvt_74e694103cf02b31b28db0a346da0b6b=1559791025',
    'Upgrade-Insecure-Requests':'1',
    }
    if __name__ == '__main__':
        url = 'http://www.heibanke.com/lesson/crawler_ex01/'
        data = {
        'csrfmiddlewaretoken':'fOg49OcOmWf2uqsuQMxY6yVvE6YHLnE9',
        'username':'fanbinglin',
        'password':'12',
        }
        for x in range(1,31,1):
            data['password'] = str(x)
            response = requests.post(url,headers=header,data=data)
            response.encoding='utf-8'
            print(x,bf(response.text,'html.parser').select_one('h3').text)

注意点：用post请求，还要用headers

执行结果：
