Biligrab 0.94: 临时修复API受限,即返回error.mp4问题

这样0.93有可能是最短命的一个版本了。。。。
好吧,玩到底。
重写了API逻辑,如果受限,直接换假UA。
要亲命啊。

    -h: Default: None
        Print this usage file.
    -a: Default: None
        The av number.
        If not set, Biligrab will use the falloff interact mode.
    -p: Default: 1
        The part number.
        Support "~", "," and mix use.
        Examples:
            Input        Output
              1           [1]
             1,2         [1, 2]
             1~3        [1, 2, 3]
            1,2~3       [1, 2, 3]
    -s: Default: 0
    Source to download.
    0: The original API source, can be Letv backup,
       and can failed if the original video is not avalable(e.g., deleted)
    1: The CDN API source, "oversea accelerate".
       Can be MINICDN backup in Mainland China or oversea.
       Good to bypass some bangumi's limit.
    2: Force to use the original source.
       Use Flvcd to parase the video, but would fail if
       1) The original source DNE, e.g., some old videos
       2) The original source is Letvcloud itself.
       3) Other unknown reason(s) that stops Flvcd from parase the video.
    For any video that failed to parse, Biligrab will try to use Flvcd.
    (Mainly for oversea users regarding to copyright-restricted bangumies.)
    If the API is blocked, Biligrab would fake the UA.
    -c: Default: ./bilicookies
    The path of cookies.
    Use cookies to visit member-only videos.
    -d: Default: None
    Set the desired download software.
    Biligrab supports aria2c(16 threads), axel(20 threads), wget and curl by far.
    If not set, Biligrab will detect an avalable one;
    If none of those is avalable, Biligrab will quit.
    For more software support, please open an issue at https://github.com/cnbeining/Biligrab/issues/
    -v Default:None
    Set the desired download software.
    Biligrab supports ffmpeg by far.
    If not set, Biligrab will detect an avalable one;
    If none of those is avalable, Biligrab will quit.
    For more software support, please open an issue at https://github.com/cnbeining/Biligrab/issues/
    Make sure you include a *working* command line example of this software!

    av1674693 会解析出一个「现在下载乐视视频客户端,送七天会员无广告」的5秒广告。
    听说 iOS、WP 客户端等也躺枪了。
    但是网页播放器没有挂,bilibili 助手也没有挂。
    求研究。

      API返回错误。
      不是我们可以解决的。
      所谓的网页播放器走的不是一个API。懒得反编译了,但是走的不是一个东西。
      助手?需要看他源码。他是开源的吗?

        1、Bilibili 助手,一个 Chrome 扩展,Zhuogu 写的,在 GitHub 上,开源。
        2、网页播放器我反编译过,硬是找不到 API Key 放在哪。
        3、助手虽然最后也是调用 Flash 播放器,但是有备用的 HTML5 播放器和下载功能,所以后者是走 API,可以研究。

          看着迷糊。。。JS苦手。
          他是什么原理?调用谁的API呢。。。
          网页播放器混淆了,不看了。Key我们知道,但是不知道secret。
          现在我这里不报问题了。
          其实我的思路是,用乐视云,强制做所有新番的源,并白名单替换。绝对准确,但是需要较多人力。也HTML5友好。但是我没有这个需求,留给别人研究了。。。不难是不难,数据库谁来维护是个问题。

      倒是有一个办法可以解决:
      本地维护一个乐视云的list,然后挨个替换。
      倒是不难。
      但是放出去就会被水表。所以只能小范围用。
      问题是我这个小范围的人都不需要这种小把戏就能看。。。。。。所以没啥意思。。。

      Biligrab的目标不是新番的下载。如果能下载纯属侥幸,如果不能则也没办法。让黑科技琢磨黑科技去吧。。。
