Python爬虫破解登陆哔哩哔哩的方法

写在前面

作为一名找不到工作的爬虫菜鸡人士来说，登陆这一块肯定是个比较大的难题。 从今天开始准备一点点对大型网站进行逐个登陆破解。加深自己爬虫水平。

环境搭建

PC端登陆

全部代码：

’’’PC登录哔哩哔哩’’’class Bilibili_For_PC(): def __init__(self, **kwargs): for key, value in kwargs.items(): setattr(self, key, value) self.session = requests.Session() self.__initialize() ’’’登录函数’’’ def login(self, username, password, crack_captcha_func=None, **kwargs): # 若参数中给入代理,则设置 self.session.proxies.update(kwargs.get(’proxies’, {})) # 是否需要验证码 is_need_captcha = False while True: # 需要验证码 if is_need_captcha:captcha_img = self.session.get(self.captcha_url, headers=self.captcha_headers).contentdata = {’image’: base64.b64encode(captcha_img).decode(’utf-8’)}captcha = self.session.post(self.crack_captcha_url, json=data).json()[’message’] # 获得key值 appkey = ’1d8b6e7d45233436’ data = { ’appkey’: appkey, ’sign’: self.__calcSign(’appkey={}’.format(appkey)) } response = self.session.post(self.getkey_url, data=data) response_json = response.json() key_hash = response_json[’data’][’hash’] pub_key = rsa.PublicKey.load_pkcs1_openssl_pem(response_json[’data’][’key’].encode(’utf-8’)) # 模拟登录 if is_need_captcha:data = 'access_key=&actionKey=appkey&appkey={}&build=6040500&captcha={}&challenge=&channel=bili&cookies=&device=pc&password={}&permission=ALL&seccode=&subid=1&ts={}&username={}&validate=' .format(appkey, captcha, urllib.parse.quote_plus(base64.b64encode(rsa.encrypt(’{}{}’.format(key_hash, password).encode(), pub_key))), int(time.time()), urllib.parse.quote_plus(username)) else:data = 'access_key=&actionKey=appkey&appkey={}&build=6040500&captcha=&challenge=&channel=bili&cookies=&device=pc&password={}&permission=ALL&seccode=&subid=1&ts={}&username={}&validate=' .format(appkey, urllib.parse.quote_plus(base64.b64encode(rsa.encrypt(’{}{}’.format(key_hash, password).encode(), pub_key))), int(time.time()), urllib.parse.quote_plus(username)) data = '{}&sign={}'.format(data, self.__calcSign(data)) response = self.session.post(self.login_url, data=data, headers=self.login_headers) response_json = response.json() # 不需要验证码, 登录成功 if response_json[’code’] == 0 and response_json[’data’][’status’] == 0:for cookie in response_json[’data’][’cookie_info’][’cookies’]: self.session.cookies.set(cookie[’name’], cookie[’value’], domain=’.bilibili’)print(’[INFO]: Account -> %s, login successfully’ % username)infos_return = {’username’: username}infos_return.update(response_json)return infos_return, self.session # 需要识别验证码 elif response_json[’code’] == -105:is_need_captcha = True # 账号密码错误 elif response_json[’code’] == -629:raise RuntimeError(’Account -> %s, fail to login, username or password error’ % username) # 其他错误 else:raise RuntimeError(response_json.get(’message’)) ’’’计算sign值’’’ def __calcSign(self, param, salt='560c52ccd288fed045859ed18bffd973'): sign = hashlib.md5(’{}{}’.format(param, salt).encode(’utf-8’)) return sign.hexdigest() ’’’初始化’’’ def __initialize(self): # 登陆请求头 self.login_headers = {’Content-type’: ’application/x-www-form-urlencoded’} # 破解验证码请求头 self.captcha_headers = {’Host’: ’passport.bilibili.com’} # 获取key密钥URL self.getkey_url = ’https://passport.bilibili.com/api/oauth2/getKey’ # 获取登陆URL self.login_url = ’https://passport.bilibili.com/api/v3/oauth2/login’ # 获取验证码URL self.captcha_url = ’https://passport.bilibili.com/captcha’ # 破解网站来自: https://github.com/Hsury/Bilibili-Toolkit # 破解验证码URL self.crack_captcha_url = ’https://bili.dev:2233/captcha’ # 请求头都得加这个 self.session.headers.update({’User-Agent’: 'Mozilla/5.0 BiliDroid/5.51.1 (bbcallen@gmail.com)'})

移动端登陆

移动端与PC端类似，网址URL差异以及请求头差异。在此不过多介绍。 全部代码：

’’’移动端登录B站’’’class Bilibili_For_Mobile(): def __init__(self, **kwargs): for key, value in kwargs.items(): setattr(self, key, value) self.session = requests.Session() self.__initialize() ’’’登录函数’’’ def login(self, username, password, crack_captcha_func=None, **kwargs): self.session.proxies.update(kwargs.get(’proxies’, {})) # 是否需要验证码 is_need_captcha = False while True: # 需要验证码 if is_need_captcha:captcha_img = self.session.get(self.captcha_url, headers=self.captcha_headers).contentdata = {’image’: base64.b64encode(captcha_img).decode(’utf-8’)}captcha = self.session.post(self.crack_captcha_url, json=data).json()[’message’] # 获得key值 appkey = ’bca7e84c2d947ac6’ data = { ’appkey’: appkey, ’sign’: self.__calcSign(’appkey={}’.format(appkey)) } response = self.session.post(self.getkey_url, data=data) response_json = response.json() key_hash = response_json[’data’][’hash’] pub_key = rsa.PublicKey.load_pkcs1_openssl_pem(response_json[’data’][’key’].encode(’utf-8’)) # 模拟登录 if is_need_captcha:data = 'access_key=&actionKey=appkey&appkey={}&build=6040500&captcha={}&challenge=&channel=bili&cookies=&device=phone&mobi_app=android&password={}&permission=ALL&platform=android&seccode=&subid=1&ts={}&username={}&validate=' .format(appkey, captcha, urllib.parse.quote_plus(base64.b64encode(rsa.encrypt(’{}{}’.format(key_hash, password).encode(), pub_key))), int(time.time()), urllib.parse.quote_plus(username)) else:data = 'access_key=&actionKey=appkey&appkey={}&build=6040500&captcha=&challenge=&channel=bili&cookies=&device=phone&mobi_app=android&password={}&permission=ALL&platform=android&seccode=&subid=1&ts={}&username={}&validate=' .format(appkey, urllib.parse.quote_plus(base64.b64encode(rsa.encrypt(’{}{}’.format(key_hash, password).encode(), pub_key))), int(time.time()), urllib.parse.quote_plus(username)) data = '{}&sign={}'.format(data, self.__calcSign(data)) response = self.session.post(self.login_url, data=data, headers=self.login_headers) response_json = response.json() # 不需要验证码, 登录成功 if response_json[’code’] == 0 and response_json[’data’][’status’] == 0:for cookie in response_json[’data’][’cookie_info’][’cookies’]: self.session.cookies.set(cookie[’name’], cookie[’value’], domain=’.bilibili’)print(’[INFO]: Account -> %s, login successfully’ % username)infos_return = {’username’: username}infos_return.update(response_json)return infos_return, self.session # 需要识别验证码 elif response_json[’code’] == -105:is_need_captcha = True # 账号密码错误 elif response_json[’code’] == -629:raise RuntimeError(’Account -> %s, fail to login, username or password error’ % username) # 其他错误 else:raise RuntimeError(response_json.get(’message’)) ’’’计算sign值’’’ def __calcSign(self, param, salt='60698ba2f68e01ce44738920a0ffe768'): sign = hashlib.md5(’{}{}’.format(param, salt).encode(’utf-8’)) return sign.hexdigest() ’’’初始化’’’ def __initialize(self): self.login_headers = {’Content-type’: ’application/x-www-form-urlencoded’ } self.captcha_headers = {’Host’: ’passport.bilibili.com’ } self.getkey_url = ’https://passport.bilibili.com/api/oauth2/getKey’ self.login_url = ’https://passport.bilibili.com/api/v3/oauth2/login’ self.captcha_url = ’https://passport.bilibili.com/captcha’ # 破解网站来自: https://github.com/Hsury/Bilibili-Toolkit self.crack_captcha_url = ’https://bili.dev:2233/captcha’ self.session.headers.update({’User-Agent’: 'Mozilla/5.0 BiliDroid/5.51.1 (bbcallen@gmail.com)'})
