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();                 }             }         }     } }
