博客源址： android网络编程——http post

     前一篇给出了HttpGet的实例，这一篇给出HttpPost的实例。

 public class HttpPostDemo extends Activity {
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         BufferedReader in = null;
         try {
             HttpClient client = new DefaultHttpClient();
             HttpPost request = new HttpPost("http://mysomewebsite.com/services/doSomething.do");
             List<NameValuePair> postParameters = new ArrayList<NameValuePair>();
             postParameters.add(new BasicNameValuePair("username", "test"));
             postParameters.add(new BasicNameValuePair("password", "test1234"));
             UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(
                     postParameters);

             request.setEntity(formEntity);
             HttpResponse response = client.execute(request);
             in = new BufferedReader(
                     new InputStreamReader(
                             response.getEntity().getContent()));

             StringBuffer sb = new StringBuffer("");
             String line = "";
             String NL = System.getProperty("line.separator");
             while ((line = in.readLine()) != null) {
                 sb.append(line + NL);
             }
             in.close();

             String result = sb.toString();
             System.out.println(result);
         } catch(Exception e) {
             // Do something about exceptions
         } finally {
             if (in != null) {
                 try {
                     in.close();
                 } catch (IOException e) {
                     e.printStackTrace();
                 }
             }
         }
     }
 }
