怎么用python查找网站后台地址

怎么用python查找网站后台地址？
我用的是python3.x

import re
import time
import requests
 
class GetLinksTitles():
 
    def links_titles(self):
        links_titles = []
        for i in range(211150, 211185):
            url = "https://support.apple.com/zh-cn/HT" + str(i)
            r = requests.get(url=url)
            if r.status_code == 200:
                html = r.content.decode('utf-8')
                pattern = r'<title lang="zh-CN">(.*?) - Apple 支持</title>'
                title = re.findall(pattern, html)
                links_titles.append(url)
                links_titles.append(title)
                print("地址：%s 标题：%s"%(url, title))
            else:
                print("不存在：%d"%(i))
 
        return links_titles
 
    def save_links_titles(self, links_titles):
        file = open('GetLinksTitles' + time.strftime('%Y%m%d%H%M%S') + '.txt', 'w')
        for i in range(len(links_titles)):
            text = str(links_titles[i]).replace("['", "").replace("']", "") + '\n'
            file.write(text)
 
if __name__ == '__main__':
    links_titles = GetLinksTitles().links_titles()
    GetLinksTitles().save_links_titles(links_titles)
