python爬虫实战一键检测前女友是否屏蔽你的空间,进行反拉黑

搬砖的苦行僧 559

前言:

眼前你们对“python拒绝访问”大致比较关怀,兄弟们都需要剖析一些“python拒绝访问”的相关知识。那么小编同时在网摘上搜集了一些关于“python拒绝访问””的相关内容,希望你们能喜欢,我们一起来了解一下吧!

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:requestslxmlthreadpoolselenium

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 = ';    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 = ';    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 = ';    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 = ";        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': ';        }        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!!")
