在nodejs中使用fs的绝对路径

Question

I am trying to pipe an http audio stream from my nodejs server:

var streamPath = 'http://127.0.0.1:1485/mystream.mp3';
var stat = fs.statSync(streamPath);
response.writeHead(200, {'Content-Type': 'audio/mpeg','Content-Length': stat.size});
fs.createReadStream(streamPath).pipe(response);

The problem is that fs doesn't like the absolute path and I get the following error:

Error: ENOENT: no such file or directory, stat 'C:\\myserver\\http:\\127.0.0.1:1485\\mystream.mp3'

I can't find a way to use the absolute path . Is this even possible using fs ?

Answer 1

'http://127.0.0.1:1485/mystream.mp3' is not an absolute path, it's a URL.

Absolute paths are something like /home/x/dir/file.txt on your filesystem.

If you want to get a stream from a URL then you need to use http or request . Or you need to use a path on your filesystem and not a URL if you want to get a file on your filesystem without using the network.

fs.createReadStream can only open local file in your filesystem.

For more details, see:

• https://nodejs.org/api/fs.html

To get a file over a network, see:

• https://www.npmjs.com/package/request
• https://www.npmjs.com/package/request-promise

You are trying to access a remote resource through fs - that is wrong. fs is meant to be used for the Local Filesystem . If you want to access any remote resource you have to use http or https . However if I see things correctly you are trying to access your localhost , which should work.

Your Application is trying to access following file: C:\\myserver\\http:\\127.0.0.1:1485\\mystream.mp3 if you look closely that can't work. Your Path is mixed with your local path and a remote source (which is localhost actually). Try to fix your path, that should solve your problem. Keep in mind that fs will only work on your local system.

You should also think about fs.statSync this will block everything else until its finished.
