Android開發中如何執行POST請求

String uriAPI = "http://192.168.1.100:8080/test/test.jsp"; //這是我測試的本地,大家可以隨意改
        /*建立HTTPost對象*/
        HttpPost httpRequest = new HttpPost(uriAPI);
        /*
         * NameValuePair實現請求參數的封裝
        */
        List <NameValuePair> params = new ArrayList <NameValuePair>();
        params.add(new BasicNameValuePair("u", "沈大海"));
        params.add(new BasicNameValuePair("p", "123"));
        try
        {
          /* 添加請求參數到請求對象*/
          httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
          /*發送請求並等待響應*/
          HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);
          /*若狀態碼爲200 ok*/
          if(httpResponse.getStatusLine().getStatusCode() == 200)
          {
            /*讀返回數據*/
            String strResult = EntityUtils.toString(httpResponse.getEntity());
            mTextView1.setText(strResult);
          }
          else
          {
            mTextView1.setText("Error Response: "+httpResponse.getStatusLine().toString());
          }
        }
        catch (ClientProtocolException e)
        {
          mTextView1.setText(e.getMessage().toString());
          e.printStackTrace();
        }
        catch (IOException e)
        {
          mTextView1.setText(e.getMessage().toString());
          e.printStackTrace();
        }
        catch (Exception e)
        {
          mTextView1.setText(e.getMessage().toString());
          e.printStackTrace();
        } 
         ////大家能根據這個代碼實現個android用戶登陸嗎?
