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
Python 3.7.7环境，Mac电脑测试
Python内置库
第三方库：rsa、urllib、requests
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).content
data = {\'image\': base64.b64encode(captcha_img).decode(\'utf-8\')}

}
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

response_json = response.json()
# 不需要验证码, 登录成功

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。

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
