title: java DropBox SDK generate token with Redirect
body: <p>after reading the official Dropbox documentation, I managed to write this code to authenticate the user with DropBox and get his access token. The user has to copy and paste the token, I don't like this step and I noticed that some developer can use the <code>withRedirect()</code> method of the <code>DbxWebAuth</code> class.
  There is an example for using redirect, but it is for web applications and I was unable to adapt it to my desktop app. Have any of you had anything to do with this?
  This is currently my code</p>
  
  <pre><code> public static void main(String[] args) throws Exception {
  
      String accessToken = "";
      String userLocale = null;
      DbxRequestConfig requestConfig = new DbxRequestConfig("text-edit/0.1", userLocale);
      DbxAppInfo appInfo = new DbxAppInfo("myString", "myString");
      DbxWebAuth auth = new DbxWebAuth(requestConfig, appInfo);
      DbxWebAuth.Request requestAuth = DbxWebAuth.newRequestBuilder().withNoRedirect().build();
      String authorizeUrl = auth.authorize(requestAuth);
  
      System.out.println("1. Go to " + authorizeUrl);
      System.out.println("2. Click \"Allow\" (you might have to log in first).");
      System.out.println("3. Copy the authorization code.");
  
      //Abrimos el enlace de autenticación del paciente en la carpeta de DropBox
      try {
          URL authenticationURL = new URL(authorizeUrl);
          Desktop.getDesktop().browse(authenticationURL.toURI());
  
      } catch (Exception e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      }
      JFrame frame1 = new JFrame("InputDialog Example #2");
      frame1.setAlwaysOnTop(true);
  
      String code = JOptionPane.showInputDialog(frame1, "Insert verification code");
  
      System.out.println(code);
      code = code.trim();
  
      try {
          DbxAuthFinish authFinish = auth.finishFromCode(code);
  
          accessToken = authFinish.getAccessToken();
  
      } catch (Exception e) {
  
      }
  }
  </code></pre>
