二、扫码登陆bilibili

考虑到B站移动滑块登陆比较难而且成功率一般
故而采用了简单的二维码登陆
至少常用的PC+手机的网站都支持二维码登录

滑块登陆链接：

一、登陆流程
1、判断用户是否已经登录了

Get https://account.bilibili.com/home/userInfo

2、获取二维码地址

Get https://passport.bilibili.com/qrcode/getLoginUrl

3、根据地址生成二维码

pip install qrcode
pip install matplotlib

4、 循环判断是否扫码

Post https://passport.bilibili.com/qrcode/getLoginInfo！
data={
        'oauthKey':oauthKey,
        'gourl': 'https://passport.bilibili.com/account/security'
 }

4、获取个人信息

Get https://api.live.bilibili.com/User/getUserInfo

代码实现

二、API层 api.py

1. API应满足单例模式
2. ajax 负责管理所有请求
3. 添加Login类负责登录
4. 添加统一接口类BilibiliAPI

from utils import singleton
def ajax(s,url,method='GET',data=None):
    if method=='GET':return http.get(s,url,data)
    else:return http.post(s,url,data)

class Login():
    def isLogin(self,s):
        url="https://account.bilibili.com/home/userInfo"
        return ajax(s,url)

    def get_vdcode(self,s):
        url="https://passport.bilibili.com/qrcode/getLoginUrl"
        return ajax(s,url)

    def loop_vdcode(self,s,oauthKey):
        url="https://passport.bilibili.com/qrcode/getLoginInfo"
        data={
                'oauthKey':oauthKey,
                'gourl': 'https://passport.bilibili.com/account/security'
            }
        return ajax(s,url,'POST',data)
@singleton
class BilibiliAPI():pass
BilibiliAPI.Login=Login()

三、服务层 server.py

from api import BilibiliAPI as API
class Login():
    def __init__(self,s):
        self.s=s
        self.oauthKey=''
        self.s._type='json'
    def isLogin(self):
        r=API.Login.isLogin(self.s)
        if r['code']==-101:return False
        else:return self.get_info()
    def get_info(self):
        r=API.User.get_info(s)
        self.info=r['data']
        return True
    def get_vdcode(self):
        r=API.Login.get_vdcode(self.s)
        code_url=r['data']['url']
        img=self.make_vdcode(code_url)
        self.show_img(img)
        self.oauthKey=r['data']['oauthKey']
    def show_img(self,img):
        import matplotlib.pyplot as plt
        plt.imshow(img)  
        plt.show()
    def make_vdcode(self,code_url):
        import qrcode
        return qrcode.make(code_url)
    def loop_vdcode(self):
        import time
        r=API.Login.loop_vdcode(self.s,self.oauthKey)
        while not r['status']:
            time.sleep(1)
            r=API.Login.loop_vdcode(self.s,self.oauthKey)
            if r['data']==-2:
                print('二维码已过期')
                break
        if r['status']:self.info=r['data']
        return r['status']
