node.js - React-native-track-player 不为直播发送标题内容范围

Question

在 react-native-track-player 库的帮助下，尝试使用 React native 和 Nodjs 创建一个真正的音频流应用程序和服务器来播放音频。一切正常，但是当涉及到来自服务器的真正实时流时，react-native-track-player 没有发送任何内容范围，因此服务器将使用内容范围响应部分内容 206 状态。

有人对此有所了解吗？

这是我为服务器准备的：

const getLocalFileSubLocation = async (req, res) => {

const { location, sub_location, filename } = req.params

const fileLocation = path.join(UPLOAD_DIR, location, sub_location, filename)

if (!fs.existsSync(fileLocation)) return Resp.notFound(res)

const fileSize = fs.statSync(fileLocation).size

const contentType = mimeTypes.lookup(fileLocation)

if (contentType !== 'audio/mpeg') return fs.createReadStream(fileLocation).pipe(res)

const range = req.headers.range ? req.headers.range : "bytes=0-"
const CHUNK_SIZE = 10 ** 6 / 2; // 1mb

let [start, end] = range.replace(/bytes=/, "").split("-")

start = parseInt(start, 10)
end = start + CHUNK_SIZE

res.writeHead(206, {
    "Content-Range": `bytes ${start}-${end}/${fileSize}`,
    "Accept-Ranges": "bytes",
    "Content-Length": end - start + 1,
    "Content-Type": contentType,
});

fs.createReadStream(fileLocation, { start, end }).pipe(res)

}

router.get("/:location/:sub_location/:filename", getLocalFileSubLocation)

另一方面音频播放器：

 await TrackPlayer.setupPlayer({
    maxCacheSize: 1048576,
    waitForBuffer: true,
});

export const onAddTrack = async (song: any) => {
const track: Track = {
    id: song._id,
    title: song.title,
    url: FILE_URL + song.url,
    artist: song.singer?.name,
    description: song.description,
    artwork: FILE_URL + song.cover,
};
await TrackPlayer.add(track);

};

这是标题的样子：

    { 'icy-metadata': '1',
  'user-agent':
   'react-native-track-player/1.0 (Linux;Android 11) ExoPlayerLib/2.11.4',
  'accept-encoding': 'identity',
  host: '143.244.142.104:8000',
  connection: 'Keep-Alive' }

这是流式 uri 的示例：http://143.244.142.104:8000/file/songs/audios/default.mp3
