IOException for URL

  • Follow


   When I try the code below with "http://www.google.com/search?source=ig&hl=en&rlz=&q=something" in the URLs.txt file, I get anIOException error.  The server is returning an HTTP response code403.  However, when I open the same URL in my browser, it worksfine.    A different but similarly formated URL to another server workedfine.  Maybe this server is expection something additional?      I am new at this, and I wonder if it is obvious what theproblems is.Thanks, Alan// download text content of URLimport java.net.*;import java.io.*;public class URLget{   public static void main ( String[] args ) throws IOException   {      try      {	   BufferedReader infile = new BufferedReader(newFileReader("URLs.txt"));         PrintWriter out = new PrintWriter(newFileOutputStream("downloaded.html"));         String aURL, str;         while ((aURL = infile.readLine()) != null)         {            URL url = new URL(aURL);            System.out.println(aURL);            BufferedReader in = new BufferedReader(newInputStreamReader(url.openStream()));            while ((str = in.readLine()) != null)            {               out.println(str);            }            in.close();         }         infile.close();         out.close();      }      catch (MalformedURLException e) {e.printStackTrace();}      catch (IOException e) {e.printStackTrace();}   }}

Maybe this server is expection something additional?I think Google tests on browser type.In 2004 the following worked:          URL url = new URL("http://www.google.dk/search?q=hej");          HttpURLConnection con = (HttpURLConnection)url.openConnection();          con.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");          con.setRequestProperty("Referrer", "http://www.google.dk/");          con.connect();          if(con.getResponseCode() == HttpURLConnection.HTTP_OK) {             InputStream is = con.getInputStream();             byte[] b = new byte[1000];             int n;             while((n = is.read(b)) >= 0) {                System.out.println(new String(b,0,n));             }             is.close();          } else {             System.out.println(con.getResponseCode() + " " + con.getResponseMessage());          }          con.disconnect();Arne
