Question

I have a QR code reader in X Code, and when it detects a web page it should open a web view.
It works like a charm, though it can’t detect an audio file.
I have a link, which loads an audio in a browser, and in my app redirects to an error.
This is the url.

In a browser the .html become mp3 and the audio is playing automatically.

How can I detect whether it is an audio or a website?

Answer 1

All you can do is hit the URL and look at the Content-Type header returned.

You can use a HEAD request where supported, and fall back to GET if needed, and simply disconnect once you have the appropriate headers.
