Как установить длину контента потока MP3 в Nodejs
var http = require('http'),
url = require('url'),
fs = require('fs'),
filePath = '/home/risto/Downloads/oleg.mp4',
stat = fs.statSync(filePath);
http.createServer(function(request, response) {
const fileSize = stat.size;
const range = request.headers.range;
if (range) {
const parts = range.replace(/bytes=/, "").split("-");
const start = parseInt(parts[0], 10);
const end = parts[1]
? parseInt(parts[1], 10)
: fileSize - 1;
const chunksize = (end - start) + 1;
const readStream = fs.createReadStream(filePath, { start, end });
const head = {
'Content-Range': `bytes ${start}-${end}/${fileSize}`,
'Accept-Ranges': 'bytes',
'Content-Length': chunksize,
'Content-Type': 'video/mp4',
};
response.writeHead(206, head);
readStream.pipe(response);
} else {
const head = {
'Content-Length': fileSize,
'Content-Type': 'video/mp4',
};
response.writeHead(200, head);
fs.createReadStream(filePath).pipe(response);
}
})
.listen(2000);
