 import requests
 from BeautifulSoup import BeautifulSoup

 def request_ctf5():
     f = open("out.txt", "w")
     for i in range(1, 2000):
         url = 'http://ctf5.simplexue.com/8/index.php?id=' + str(i)
         res = requests.get(url)
         res_table = BeautifulSoup(res.content).find('table')
         tr_1 = res_table.findAll('tr')[0]
         try:
             tr_2 = res_table.findAll('tr')[1]
         except:
             print >> f, "no id and content"
             continue
         id_t = tr_2.findAll('td')[0].text
         content_t = tr_2.findAll('td')[1].text
         if id_t and content_t:
             print >> f, "id = %s, content = %s" % (id_t, content_t)
     return

 if __name__ == '__main__':
     request_ctf5()

不断修改id访问URL2000次，分析返回的页面。
