最近发现有人QQ空间对我展开了屏蔽，咱们也不知道怎么惹到人家了，一气之下写了一个小爬虫看看到底谁把我屏蔽了。写小本本记下来！！！
准备工作
python环境：
python3.7.4
第三方库环境：
requests
lxml
threadpool
selenium
利用selenium模拟登陆获取cookie并保存到本地
def search_cookie(): # 先检测一下是否运行过
if not __import__('os').path.exists('cookie_dict.txt'):
get_cookie_json()
with open('cookie_dict.txt', 'r') as f:
cookie=json.load(f)
return cookie
def get_cookie_json(): # 无头selenium登陆
qq_number = input('请输入qq号:')
password = __import__('getpass').getpass('请输入qq密码:')
from selenium import webdriver
login_url = 'https://i.qq.com/'
chrome_options =Options()
chrome_options.add_argument('--headless')
driver = webdriver.Chrome(options=chrome_options)
driver.get(login_url)
driver.switch_to_frame('login_frame')
driver.find_element_by_xpath('//*[@id="switcher_plogin"]').click()
time.sleep(1)
driver.find_element_by_xpath('//*[@id="u"]').send_keys(qq_number)
driver.find_element_by_xpath('//*[@id="p"]').send_keys(password)
time.sleep(1)
driver.find_element_by_xpath('//*[@id="login_button"]').click()
time.sleep(1)
cookie_list = driver.get_cookies()
cookie_dict = {}
for cookie in cookie_list:
if 'name' in cookie and 'value' in cookie:
cookie_dict[cookie['name']] = cookie['value']
with open('cookie_dict.txt', 'w') as f:
json.dump(cookie_dict, f)
return True
找到查看好友的接口
进入我的空间，点击 F12 检查界面，将 Network 清空后点击好友界面。
首选盲猜好友列表含有friend字段。直接选择搜索发现出来一些数据，挨个查找之后发现好友字段。保存当前获得的 url 供日后查询。
破解data里面的加密参数
看到只有一个 g_tk 加密参数就很激动，就一个加密！去 Sources 里面搜索 g_tk 取值到底是什么加密，发现是个函数点进去看后发现是个简单的小加密。可以写 python 代码。
Python代码如下：
def get_g_tk(): # QQ空间的加密算法
p_skey = cookie['p_skey']
h = 5381
for i in p_skey:
h = (h << 5) ord(i)
g_tk = h & 214748364
return g_tk
在QQ空间好友栏获取好友列表
拿到加密参数后，接下来我们就只需要进刚才所说的空间好友栏页面将所有的好友的QQ号抓下来，用urllib.parse.urlencode(data)将参数转成我们常见的url后面缀了一长串&&&的形式与原始链接拼接，然后就可以带上cookies发送请求获取json数据，
def get_friends_uin(g_tk): # 获得好友的QQ号信息
yurl = 'https://user.qzone.qq.com/proxy/domain/r.qzone.qq.com/cgi-bin/tfriend/friend_ship_manager.cgi?'
data = {
'uin': cookie['ptui_loginuin'],
'do': 1,
'g_tk': g_tk
}
url = yurl urllib.parse.urlencode(data)
res=requests.get(url, headers = headers, cookies = cookie)
r = res.text.split('(')[1].split(')')[0]
friends_list=json.loads(r)['data']['items_list']
friends_uin=[]
for f in friends_list:
friends_uin.append(f['uin'])
return friends_uin
找到屏蔽我的"狠人"
拿到好友的QQ号之后，咱们就能直接访问好友的空间了，但是好友设置了拒绝访问，一定要拿小本本记下来！
def get_blacklist(friends): # 查询被挡好友的QQ号，用小本本记下来!
access_denied=[] # 拉黑笔记，小本本记下来！
yurl = 'https://user.qzone.qq.com/'
for friend in friends:
print("开始检查:" str(friend))
url = yurl str(friend)
res = requests.get(url,headers=headers,cookies=cookie)
tip = etree.HTML(res.text).xpath('/html/body/div/div/div[1]/p/text()')
if len(tip) > 0:
#if tip[0][:7] == "主人设置了权限":
print(str(friend) "把我拉黑了!")
access_denied.append(friend)
return access_denied
拉黑这帮重色轻友的人！进入自己心灵想进去的地方，拉黑他们！
发现只有一个 post 请求，那应该就只能是这个了。
看了眼所需要的参数，自己的号，拉黑的号，自己的空间，加上一个无用参数和刚才所获得加密参数。
越想越气，写代码！
def pull_black(): # 拉黑，必须拉黑！
global cookie
cookie = search_cookie()
with open('access_denied.txt', 'r') as f:
access_denied = f.readlines()
for fake_friend in access_denied:
fake_friend = fake_friend.split('\n')[0]
yurl = "https://user.qzone.qq.com/proxy/domain/w.qzone.qq.com/cgi-bin/right/cgi_black_action_new?"
g_tk = get_g_tk()
url_data = {'g_tk': g_tk}
data = {
'uin': cookie['ptui_loginuin'],
'action': '1',
'act_uin': fake_friend,
'fupdate': '1',
'qzreferrer': 'https://user.qzone.qq.com/1223411083'
}
url = yurl urllib.parse.urlencode(url_data)
res=requests.post(url, headers = headers, data=data, cookies = cookie)
print(str(fake_friend) "已被您拉黑")
print("都拉黑了！解气！！")
