用Node.js做了一个接口服务器，但是通过以下方式POST过来的参数获取不到，请问该如何获取？？？

java 代码调用方式如下：

   /*建立HTTPost对象*/
    HttpPost httpRequest = new HttpPost(uriAPI); 
    /*
     * NameValuePair实现请求参数的封装
    */
    List <NameValuePair> params = new ArrayList <NameValuePair>(); 
    params.add(new BasicNameValuePair("u", "沈大海")); 
    params.add(new BasicNameValuePair("p", "123")); 
    try 
    { 
      /* 添加请求参数到请求对象*/
      httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8)); 
      /*发送请求并等待响应*/
      HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest); 
      /*若状态码为200 ok*/
      if(httpResponse.getStatusLine().getStatusCode() == 200)  
      { 
        /*读返回数据*/
        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();  
    }
