Android下通过HttpClient执行 HTTP POST 请求

public void postData() {      // Create a new HttpClient and Post Header      HttpClient httpclient = new DefaultHttpClient();      HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");         try {          // Add your data          List<NameValuePair> nameValuePairs = new ArrayList&lt;NameValuePair&gt;(2);          nameValuePairs.add(new BasicNameValuePair("id", "12345"));          nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));          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      }  }
