发送POST数据Android

Question

我正试图在我的应用中通过该网站http://www.rossnet.pl/Start.aspx发布新闻通讯。我正在尝试在我的Android应用程序中发送POST数据，一切看起来都很好，但仍然没有电子邮件列在新闻通讯列表中。我的代码：

 public class MainActivity extends Activity {

private Button b;
private int TIMEOUT_MS = 10000;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    b = (Button) findViewById(R.id.button1);
    b.setOnClickListener(new View.OnClickListener() {

        public void onClick(View arg0) {
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
            nameValuePairs.add(new BasicNameValuePair(
                    "dnn_ctr1741_ViewNewsletterSubscribe_tb_hidden",
                    "k.o.p.t.u.s@gmail.com"));
            nameValuePairs
                    .add(new BasicNameValuePair(
                            "__EVENTVALIDATION",
                            "/wEWCwLbrPQDApzVwckKApul3dEEArGyrMYCAq6r4NoEAujm+N8IApWbjNwEAsHhzqkPAqD4jIQPAv7k8bICAtH1idgOYOyKdndX8LHZqHjXpX5IdUMCNvc="));

            nameValuePairs.add(new BasicNameValuePair("__EVENTTARGET",
                    "dnn$ctr1741$ViewNewsletterSubscribe$lbtn_subscribe"));

            nameValuePairs.add(new BasicNameValuePair("dnn$ctr1741$ViewNewsletterSubscribe$tb_hidden",
                    "k.o.p.t.u.s@gmail.com"));
            nameValuePairs.add(new BasicNameValuePair("ScriptManager_TSM",
                    ";;System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35:en:111e8464-2436-44db-9b34-0d84ed5253c8:ea597d4b:b25378d2"));

            HttpClient client = new DefaultHttpClient();
            HttpConnectionParams.setConnectionTimeout(
                    client.getParams(), TIMEOUT_MS);
            HttpConnectionParams.setSoTimeout(client.getParams(),
                    TIMEOUT_MS);
            HttpPost post = new HttpPost("http://www.rossnet.pl/Start.aspx");
            try {
                post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                Log.d("debug", "lala1");
            } catch (UnsupportedEncodingException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            } // with list of key-value pairs
            try {
                Log.d("debug", "test1");
                client.execute(post, new ResponseHandler(){

                    public Object handleResponse(HttpResponse response)
                            throws ClientProtocolException, IOException {
                        Log.d("debug", "test2");
                        return null;
                    }});
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            Log.d("debug", "test3");
        }
    });
}

}
