How to download a pdf file programmatically from a webpage with .html extension?

Question

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:

Answer 1

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.

Answer 2

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();
    }
}
