  1. 前言
  2. 正确方式
    1. 获取原视频链接
      1. cid如何获取
  3. 播放
  • 总结

    • 前言

    由于想写一个Android练手项目，可以听取b站视频（虽然b站自带了听视频功能，但是我就是想写，略略略）

    所以需要android的MediaPlayer来播放b站视频

    需要获得b站视频的原视频链接，并有权限下载它

    中间走过很多弯路，最后终于在很多博客的帮助下解决了

    这篇博客最有用：

    博客链接

    最后也是成功实现了播放b站视频（的音频）

    正确方式

    获取原视频链接

    请求下面这个api

    1
    https://api.bilibili.com/x/player/playurl?otype=json&fnver=0&fnval=2&player=1&qn=64&bvid=[bv号]&cid=[视频cid]

    [bv号] 和 [视频cid] 替换为目标视频的bv和cid

    返回结果示例

    MediaPlayer player = new MediaPlayer();
    Uri uri = Uri.parse(url);
    Map<String, String> headers = new HashMap<>();
    //设置请求头，不设置将无权限播放
    headers.put("Referer","https://www.bilibili.com");
    headers.put("Sec-Fetch-Mode", "no-cors");
    headers.put("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.90 Safari/537.36");
    player.setDataSource(getApplicationContext(),uri, headers);
    player.prepare();
    player.start();

    这样会播放视频的音频

    可通过相关代码播放视频

    总结

    1. 获取cid
    2. 获取视频原链接
    3. 设置请求头
      headers.put("Referer","https://www.bilibili.com"); headers.put("Sec-Fetch-Mode", "no-cors"); headers.put("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.90 Safari/537.36");
    4. 请求
