代码::

   DefaultHttpClient UserIDclient = new DefaultHttpClient();
                 HttpPost httppost = new HttpPost(url);
                 List<BasicNameValuePair> nvps = new ArrayList<BasicNameValuePair>();
                 nvps.add(new BasicNameValuePair("username","password"));
                 UrlEncodedFormEntity p_entity = new UrlEncodedFormEntity(nvps,HTTP.UTF_8);
                 httppost.setEntity(p_entity);
                 HttpResponse response = UserIDclient.execute(httppost);
                 HttpEntity resEntity = response.getEntity();
                    Returned = EntityUtils.toString(resEntity);
                    System.out.println("ans is :: "+ Returned);

            System.out.println("Returned ======>>> "+Returned);

第一件事：

检查“返回”字符串是否为空。

第二件事：

有一件事我注意到你已经写了两次以下的行，在传递用户名和密码之前需要调用execute（）方法：

HttpResponse response = httpclient.execute(post);
HttpEntity entity = response.getEntity();
Returned = EntityUtils.toString(entity);

相反，您的代码应为：

HttpClient httpclient = new DefaultHttpClient();
         HttpPost post = new HttpPost(url);

 List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        // Your DATA
        nameValuePairs.add(new BasicNameValuePair("ID", "username"));

        nameValuePairs.add(new BasicNameValuePair("Password", "password"));

        response.setEntity(new UrlEncodedFormEntity(nameValuePairs,
                HTTP.UTF_8));
        HttpResponse response1 = httpclient.execute(post);

        if(response1.getStatusLine().getStatusCode()==200)
        {
            HttpEntity resEntity = response1.getEntity();
            System.out.println("=========> Response => "+iStream_to_String(resEntitiy.getContent()));  

        }

//你可以从here获得iStream_to_String。

无法验证服务
