如何获得视频流与反应原生视频?

Question

我在nodejs上使用以下代码，其中我使用基于范围的视频流:

router.get('/video/:id', authenticateToken, (req, res) => {
const range = req.headers.range;
if (!range) {
res.status(400).send("Requires Range header");
}
// get video stats (about 61MB)
const videoPath = `uploads/${req.params.id}`;
const videoSize = fs.statSync(videoPath).size;
// Parse Range
// Example: "bytes=32324-"
const CHUNK_SIZE = 10 ** 6; // 1MB
const start = Number(range.replace(/D/g, ""));
const end = Math.min(start + CHUNK_SIZE, videoSize - 1);
// Create headers
const contentLength = end - start + 1;
const headers = {
"Content-Range": `bytes ${start}-${end}/${videoSize}`,
"Accept-Ranges": "bytes",
"Content-Length": contentLength,
"Content-Type": "video/mp4",
};
// HTTP Status 206 for Partial Content
res.writeHead(206, headers);
// create video read stream for this particular chunk
const videoStream = fs.createReadStream(videoPath, { start, end });
// Stream the video chunk to the client
videoStream.pipe(res);
});

但是react-native-video不发送任何范围标头，当我试图从服务器获得mp4视频时，我得到错误:

{"error": {"extra": -2147483648, "what": 1}}

使用react-native-video包:

<Video
source={{
uri: `http://*server ip*/video/${exercise.content}`,
type: 'mp4',
}}
/>

我应该用什么来代替?

express static解决我的问题。感谢@SilvanBregy

app.use('/video', express.static('uploads'))
