假设我有这个

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("pin", "date"));

当我使用下面的代码时

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://X.X.X.X/abcdef.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();

什么将是邮政的要求？ 参数如何在URL中传递？
