Question

I want to download the mp3 file from url : "http://upload13.music.qzone.soso.com/30671794.mp3", i always got java.io.IOException: Server returned HTTP response code: 403 for URL. But it's ok when open the url using browser. Below is part of my code:

BufferedInputStream bis = null; BufferedOutputStream bos = null; try {     URL url = new URL(link);      URLConnection urlConn = url.openConnection();     urlConn.addRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");      String contentType = urlConn.getContentType();      System.out.println("contentType:" + contentType);      InputStream is = urlConn.getInputStream();     bis = new BufferedInputStream(is, 4 * 1024);     bos = new BufferedOutputStream(new FileOutputStream(     fileName.toString()));​ 

Anyone could help me? Thanks in advance!

Answer 1

You can also use

System.setProperty("http.agent", "Chrome"); 

it worked for me.

//Update

Explanation

Because HttpURLConnection reads the property "http.agent" if set. You can read it here: https://www.innovation.ch/java/HTTPClient/advanced_info.html

Or you can look it up in the source code of the HttpURLConnection Class:

String agent = java.security.AccessController.doPrivileged(new sun.security.action.GetPropertyAction("http.agent"));
