I have the following simple program which reads an image from a url.
public class TestWebScrapper {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
URL imageUrl;
try {
imageUrl = new URL("https://assets.boxdice.com.au/bj_corporate/listings/1751/4618116b.jpg");
HttpURLConnection connection = (HttpURLConnection) imageUrl.openConnection();
connection.setRequestProperty(
"User-Agent",
"Mozilla/5.0 (Windows NT 6.3; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0");
BufferedImage propertImage = ImageIO.read(imageUrl);
} catch (Exception ex) {
Logger.getLogger(TestWebScrapper.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
The issue that I have this is that this gives an exception
Can't get input stream from URL!
with an message:
Received fatal alert: internal_error
I tried adding the user-agent, but the issue persists. The link works fine on a browser. This error comes only for images from this url, but does anyone know how to work around this?
You set the User-Agent
on the connection but then use the imageUrl
to load the image, so this has no effect.
Use
BufferedImage propertImage = ImageIO.read(connection.getInputStream());
instead (and close the inputstream once you are done).
