我正在尝试使用java和jsoup登录一个网站。但每次我执行post请求时，我都会得到一个IOExeption。该网站是www.seriecanal。通用域名格式。如果有人能查看html表单并告诉我是否正确创建了名称-值对，以及登录是否有任何其他明显错误，我将不胜感激。这是我的密码：

public HttpResponse postData() 
{
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://seriecanal.com/index.php?page=member");

    try 
    {

        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);


        //Get value of input "Regresa_web" because it changes each time i access the site
        String Codigo_Fuente ="";
        URL url = new URL("http://seriecanal.com/");
        URLConnection conn = url.openConnection();
        BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line = "";
        while ((line = rd.readLine()) != null) 
        {
            Codigo_Fuente= Codigo_Fuente+line;
        }
        Document Doc = Jsoup.parse(Codigo_Fuente);
        Element Regresa_WEb = Doc.getElementById("regresa_web");
        String Valor_Regresa_Web = Regresa_WEb.attr("value");


        //create name value pairs of the form
        nameValuePairs.add(new BasicNameValuePair("_UserName", "userontheweb"));
        nameValuePairs.add(new BasicNameValuePair("_Pwd", "123456789"));
        nameValuePairs.add(new BasicNameValuePair("btnLogin", "Ingresar"));
        nameValuePairs.add(new BasicNameValuePair("_submit_check", "1"));
        nameValuePairs.add(new BasicNameValuePair("remember", "ON"));
        nameValuePairs.add(new BasicNameValuePair("regresa_web", Valor_Regresa_Web));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse Response = httpclient.execute(httppost);
        return Response;

    } 
    catch (ClientProtocolException e) 
    {           
        return null;
    } 
    catch (IOException e) 
    {       
        Log.i("ERROR", e.toString());
        e.printStackTrace();
        return null;
    }
}
