我得到一个异常和代码状态为 400。我的代码有什么问题？

OAuthConsumer consumer = new DefaultOAuthConsumer("API key","Secret",SignatureMethod.HMAC_SHA1);
    OAuthProvider provider = new DefaultOAuthProvider(consumer,"http://services.digg.com/oauth/request_token","http://services.digg.com/oauth/access_token","http://digg.com/oauth/authorize");
    System.out.println("Fetching request token from Digg...");

    String authUrl = provider.retrieveRequestToken(OAuth.OUT_OF_BAND);

    System.out.println("Request token: " + consumer.getToken());
    System.out.println("Token secret: " + consumer.getTokenSecret());

    System.out.println("Now visit:\n" + authUrl
            + "\n... and grant this app authorization");
    System.out.println("Enter the PIN code and hit ENTER when you're done:");

    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String pin = br.readLine();

    System.out.println("Fetching access token from Digg...");

    provider.retrieveAccessToken(pin);

    System.out.println("Access token: " + consumer.getToken());
    System.out.println("Token secret: " + consumer.getTokenSecret());


     URL url = new URL("http://services.digg.com/2.0/story.digg");
     HttpURLConnection request =  (HttpURLConnection)url.openConnection();
     request.setDoOutput(true);
     String charset="UTF-8";
             request.setRequestProperty("story_id","20100706205455:22419803" );
             request.setRequestProperty("key",consumer.getConsumerKey() );
             request.setRequestProperty("secret",consumer.getConsumerSecret()  );
             request.setRequestProperty("access_token" ,consumer.getToken() );
             request.setRequestProperty("access_token_secret",consumer.getTokenSecret()  );

     request.setRequestProperty("Accept-Charset", charset);
    request.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=" + charset);
    OutputStream output = null;
    try {
         output = request.getOutputStream();

    } finally {
         if (output != null) try { output.close(); } catch (IOException logOrIgnore) {}
    }
    System.out.print(request.getResponseCode());

例外情况如下：
