Android排除請求不與名稱值對一起工作

在我的應用程序中，我需要使用HttpPut方法向服務器發佈一些參數。所以爲此，我使用基本身份驗證技術進行了檢查，並以這種方式獲得相同的結果。但是當我試圖用Json Volley實現時，我無法得到結果。每次它拋出服務器錯誤。Android排除請求不與名稱值對一起工作

這裏是

@Override 
     protected Void doInBackground(String... params) 
     { 
      // TODO Auto-generated method stub 

      try 
      { 
       HttpPut request = new HttpPut(params[0]); 

       Log.d("debug", "Posting URL" + params[0]); 

       String creds = String.format("%s:%s", 
         "user123", 
         "abcd"); 

       String auth = "Basic " + Base64.encodeToString(creds.getBytes(), 
         Base64.NO_WRAP); 

       request.setHeader("Authorization", 
         auth); 

       List<NameValuePair> urlParameters = new ArrayList<NameValuePair>(); 
       urlParameters.add(new BasicNameValuePair("id", "409")); 
       urlParameters.add(new BasicNameValuePair("parent_id", "0")); 
       urlParameters.add(new BasicNameValuePair("content", "I am android developer")); 
       urlParameters.add(new BasicNameValuePair("email", "[email protected]")); 
       urlParameters.add(new BasicNameValuePair("username", "King Of Masses")); 

       request.setEntity(new UrlEncodedFormEntity(urlParameters)); 

       DefaultHttpClient httpClient = new DefaultHttpClient(); 
       HttpResponse response = httpClient.execute(request); 
       HttpEntity Entity = response.getEntity(); 
       String jsondata = EntityUtils.toString(Entity); 

       Log.d("debug", 
         "Response Code:: " + response.getStatusLine().getStatusCode()); 

       Log.d("debug", 
         "Json Data in Asynctask:: " + jsondata); 

       JSONObject ljsJsonObject=new JSONObject(jsondata); 

       Log.d("debug", 
         "Json Object Data:: " + ljsJsonObject.toString()); 

      } 
      catch(ClientProtocolException e) 
      { 
       Log.d("debug", 
         "Exception" + e.toString()); 
       e.printStackTrace(); 
      } 
      catch(IOException e) 
      { 

       Log.d("debug", 
         "Exception" + e.toString()); 
       e.printStackTrace(); 
      } 
      catch(Exception e) 
      { 

       e.printStackTrace(); 
      } 
      return null; 
     }

所以在這上面的方式，我得到的結果我的預期..但我無法實現與VolleyJson同我的代碼通過使用的AsyncTask基本身份驗證:: ..任何一個可以指導我如何做到這一點。我嘗試了太多的方法一樣（getBody（），getParams（）方法），但遺憾的是沒有工作對我來說..

任何幫助將是非常感激。謝謝

幾條小道後，我終於得到了解決對於我的問題，我也得到了與VollyJson同樣的結果..在這裏，我張貼解決方案。這可能對未來的某個人有所幫助。

這是我的電話VollyJson ::

String postUrl="http://xxxxxxxxx/xxxx";

       params.add(new BasicNameValuePair("id", "409")); 
       params.add(new BasicNameValuePair("parent_id", "0"));

                       mListener); 

                 } 
                }) 
     {

Android Volley中存在一個不讀取的錯誤getParas鍵值對。

您有2個選項

使用StringRequest，然後解析到這個JSON（我用這個！） - 是這樣的 - 然後覆蓋getParams方法，你通常會做。

RequestQueue queue = Volley.newRequestQueue(this); 
String url ="http://www.google.com"; 

// Request a string response from the provided URL. 
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, 
     new Response.Listener<String>() { 
@Override 
public void onResponse(String response) { 
    JSONObject obj = new JSONObject(response); 
    //Now you can manipulate/store your JSON 

} 
    }, new Response.ErrorListener() { 
    @Override 
    public void onErrorResponse(VolleyError error) { 
     mTextView.setText("That didn't work!"); 
    } 
    }) 
{ 

protected Map<string, string=""> getParams() throws  com.android.volley.AuthFailureError { 
    Map<string, string=""> params = new HashMap<string, string="">(); 
    params.put("param1", num1); 
    params.put("param2", num2); 
    return params; 
    }; 
}; 
      // Add the request to the RequestQueue. 
      queue.add(stringRequest);

使用自定義的對象 - 類似這樣的事情

CustomRequest request = new CustomRequest(Method.POST, URL, null, new Response.Listener<JSONObject>() { 
    @Override 
    public void onResponse(JSONObject response) { 
     Toast.makeText(getActivity(), response.toString(), Toast.LENGTH_SHORT).show(); 
    } 
}, new Response.ErrorListener() { 
    @Override 
    public void onErrorResponse(VolleyError error) { 
     Toast.makeText(getActivity(), "Error.", Toast.LENGTH_SHORT).show(); 
    } 
    }) { 
    @Override 
    protected Map<String, String> getParams() throws AuthFailureError { 
     Map<String, String> params = new HashMap<String, String>(); 
     params.put("id", id); 
     params.put("password", password); 
     return params; 
    } 
    }; 
VolleySingleton.getInstance().addToRequestQueue(request);
