如何在 Android HttpPost 中发送查询参数

Question

我正在开发一个 Android 应用程序，我需要在其中使用 Web 服务。当我签入 SoapUI 时收到 200 响应（我无法附上我的 SoapUI 屏幕截图）。基本上我需要将查询参数发送到登录 Web 服务，这是一个 POST 请求。

我正在我的 Android 文件中尝试以下代码片段，但它不起作用。我做错了什么吗？

String loginUrl = "http://my-login-portal.in/LogonServlet";

List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(4);

nameValuePair.add(new BasicNameValuePair("page", "/OrderHandlingServlet?api=login"));
nameValuePair.add(new BasicNameValuePair("txtDomain", "MyDomain"));
nameValuePair.add(new BasicNameValuePair("txtUid", "user1"));
nameValuePair.add(new BasicNameValuePair("txtPwd", "pwd1"));


httppost = new HttpPost(loginUrl);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePair));                
httppost.setHeader(HTTP.CONTENT_TYPE, "application/x-www-form-urlencoded");

response = httpclient.execute(httppost);

使用此代码：

List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(4);

nameValuePair.add(new BasicNameValuePair("page", "/OrderHandlingServlet?api=login"));
nameValuePair.add(new BasicNameValuePair("txtDomain", "MyDomain"));
nameValuePair.add(new BasicNameValuePair("txtUid", "user1"));
nameValuePair.add(new BasicNameValuePair("txtPwd", "pwd1"));

HttpParams params = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(params, INSERTCONNECTIONTIMEOUT);
HttpClient client = new DefaultHttpClient(params);
HttpPost request = new HttpPost(URL);//put url here
request.setEntity(new UrlEncodedFormEntity(nameValuePair));
BasicHttpResponse httpResponse = (BasicHttpResponse) client.execute(request);
String data = StreamToString(httpResponse.getEntity().getContent());
