怎么看对方是不是把空间屏蔽了（进行反拉黑）

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！！")
