access_key相关

获取方式：模拟第三方登录

1. Request.get https://passport.bilibili.com/login/app/third ，携带参数appKey、api、sign
   三者都为固定值

 const res = await request.get('https://passport.bilibili.com/login/app/third', {
      params: {
        appkey: 27eb53fc9058f8c3,
        api: 'https://www.mcbbs.net/template/mcbbs/image/special_photo_bg.png',
        sign: '04224646d1fea004e79606d3b038c84a',
      },
      withCredentials: true,
    }
 )

2. 请求成功，返回如下内容

 {
    "code": 0,
    "status": true,
    "ts": 1691214639,
    "data": {
      "api_host": "www.mcbbs.net",
      "has_login": 1,
      "direct_login": 0,
      "user_info": {
        "mid": 123213123,
        "uname": "xxx",
        "face": "https://i0.hdslb.com/bfs/face/f52c01ddadedewf52f1959dae37ca09588fa35acc6ab.jpg"
       },
      "confirm_uri": "https://passport.bilibili.com/login/appSuccess?api=https%3A%2F%2Fwww.mcbbs.net%2Ftemplate%2Fmcbbs%2Fimage%2Fspecial_photo_bg.png&appkey=27eb53fc9058f8c3&sign=04224646d1fea004e79606d3b038c84a&mhash=8ce9da4e67d96f048a7bfcb5cb763625&confirm=1"
     }
}

4. Request.get 上述返回内容中的confirm_uri字段，会302重定向到新地址，响应头Location字段中即包含access_key字段

同样的，请求https://passport.bilibili.com/login/app/third?appkey=27eb53fc9058f8c3&api=http://link.acg.tv/forum.php&sign=67ec798004373253d60114caaad89a8c 也可以间接获取access_key

注意，在后续请求中appkey跟access_key需要是对应关系
