UrbanAirship Push API

Question

我正在尝试使用java程序构建一个简单的推送通知，将消息广播到所有Android设备，但我总是得到Connectionexception，我不知道为什么......

    URL url = new URL("https://go.urbanairship.com/api/push/broadcast/");
    // Transmit the request document
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    System.out.println("connect 1");

    connection.setDoOutput(true);   
    String auth = "*****************" + ":" + "******************";
    //connection.setRequestProperty("Authorization","Basic " + Base64.encode(auth.getBytes())); 
    connection.setRequestProperty("Authorization", "Basic " + auth);
    System.out.println("connect 2");
    connection.setDoInput(true);
    connection.setRequestMethod("POST");
    connection.setConnectTimeout(12000);
    connection.setRequestProperty("Content-Type","application/json");
    connection.setRequestProperty("Content-Length", "" + Integer.toString(bytes.length));
    connection.connect();
    System.out.println("connect 3");
    //Send request
    DataOutputStream wr = new DataOutputStream (connection.getOutputStream ());
    wr.write(bytes);
    wr.flush ();
    wr.close ();
    System.out.println("connect 5");
    //Get Response
    String responseHeader = connection.getHeaderField(0);   
    System.out.println("response header " + responseHeader);

输出：

connect 1
connect 2

关闭此缺陷。试图与Urban Airship团队合作，但他们似乎有一个错误。
