QQ空间爬虫--获取好友信息

QQ空间网页版：https://user.qzone.qq.com/

登陆后，进入设置，有一个权限设置，设置“谁能看我的空间”为好友可见，然后构造爬虫。

（1）获取Cookie

两种方式：

第一种：通过chrome F12慢慢找获取

第二种：selenium模拟登陆获取

 1 from selenium import webdriver
 2 from time import sleep
 3 import json
 4 
 5 QQ_num = \'\'
 6 QQ_s = \'\'
 7 driver = webdriver.Firefox()
 8 driver.get(\'https://user.qzone.qq.com/\' + QQ_num + \'/main\')
 9 driver.switch_to.frame(\'login_frame\')
10 #找到账号密码登陆的地方
11 driver.find_element_by_id(\'switcher_plogin\').click()
12 driver.find_element_by_id(\'u\').send_keys(QQ_num)
13 driver.find_element_by_id(\'p\').send_keys(QQ_s)
14 driver.find_element_by_id(\'login_button\').click()
15 #保存本地的cookie
16 sleep(1)
17 cookies = driver.get_cookies()
18 cookie_dic = {}
19 for cookie in cookies:
20     if \'name\' in cookie and \'value\' in cookie:
21         cookie_dic[cookie[\'name\']] = cookie[\'value\']
22     with open(\'cookie_dict.txt\', \'w\') as f:
23         json.dump(cookie_dic, f)

（2）构造链接

这个从知乎上看别人的思路，主要是g_tk的构造

（3）获取所有好友信息（主要是昵称和QQ号）

 2 import requests
 3 import csv
 4 import json

12         h = 5381
13         for i in p_skey:
14             h += (h << 5) + ord(i)
15         g_tk = h & 2147483647
16         return g_tk
17 
18     #得到uin
19     def get_uin(self):
20         uin = cookie[\'ptui_loginuin\']
21         return uin

26         friend_list = self.get_friend()
