Question

I am trying to fetch an image from an IP camera using HTTP. The camera requires HTTP basic authentication, so I have to add the corresponding request header:

URL url = new URL("http://myipcam/snapshot.jpg");
URLConnection uc = url.openConnection();
uc.setRequestProperty("Authorization", 
  "Basic " + new String(Base64.encode("user:pass".getBytes())));

// outputs "null"
System.out.println(uc.getRequestProperty("Authorization"));

I am later passing the url object to ImageIO.read(), and, as you can guess, I am getting an HTTP 401 Unauthorized, although user and pass are correct.

What am I doing wrong?

I’ve also tried new URL("http://user:pass@myipcam/snapshot.jpg"), but that doesn’t work either.

Answer 1

Issue resolved. It didn’t work because I was passing url to ImageIO.read().

Instead, passing uc.getInputStream() got it working.
