I have reviewed ALL similar questions (not only this!) on this forum and have tried ALL of those methods however still was not able to programmatically download a test file: http://pdfobject.com/markup/examples/full-browser-window.html
The following is the direct link to the test file that i am trying to download. This is a test pdf file with an open access, so anybody can use it to test a download method.
How can I download this particular file so that it has a pdf extension?
For downloading a file, perhaps you could try something like this:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.net.URLConnection;
public final class FileDownloader {
private FileDownloader(){}
public static void main(String args[]) throws IOException{
download("http://pdfobject.com/pdf/sample.pdf", new File("sample.pdf"));
}
public static void download(final String url, final File destination) throws IOException {
final URLConnection connection = new URL(url).openConnection();
connection.setConnectTimeout(60000);
connection.setReadTimeout(60000);
connection.addRequestProperty("User-Agent", "Mozilla/5.0");
final FileOutputStream output = new FileOutputStream(destination, false);
final byte[] buffer = new byte[2048];
int read;
final InputStream input = connection.getInputStream();
while((read = input.read(buffer)) > -1)
output.write(buffer, 0, read);
output.flush();
output.close();
input.close();
}
}
Let me give you a shorter solution, it comes with a library called JSoup, which BalusC often uses in his answers.
//Get the response
Response response=Jsoup.connect(location).ignoreContentType(true).execute();
//Save the file
FileOutputStream out = new FileOutputStream(new File(outputFolder + name));
out.write(response.bodyAsBytes());
out.close();
Well, you must have guessed by now, response.body()
is where the pdf is. You can download any binary file with this piece of code.
