QQ空间爬虫--获取好友信息

时间：2022-10-30 16:50:47

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

 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）
