如何使用所有XML参数值访问API post方法必须经过HTML编码

Question

我想使用一些参数访问API， 这下面我做了什么。但是它仍然不起作用，我不知道要解决这种情况，发送XML参数值所需的API必须经过HTML编码，

我曾尝试运行和调试此代码，但指针堆栈位于“ HttpResponse”部分。

              HttpClient httpclient = new DefaultHttpClient();
              HttpPost httppost = new HttpPost("URL.php");

            try {
                // Add your data
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(6);
                nameValuePairs.add(new BasicNameValuePair("Username", "pr_demo"));
                nameValuePairs.add(new BasicNameValuePair("Password", "WU6xxxxxxx1PV"));
                nameValuePairs.add(new BasicNameValuePair("msg_type", "txt"));
                nameValuePairs.add(new BasicNameValuePair("Msisdn", "Phone Numb"));
                nameValuePairs.add(new BasicNameValuePair("msisdn_sender", "ProMDemo"));
                nameValuePairs.add(new BasicNameValuePair("Message", "Hiii---"));
                nameValuePairs.add(new BasicNameValuePair("dr_url", "stardeptstore.com"));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

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

            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
            } catch (IOException e) {
                // TODO Auto-generated catch block
            }
