Question

这里我没有得到任何响应是否有任何错误在这个代码中我使用了API中的两个参数我已经存储在params虽然在Error中进来**新的JSONObject（params）** API工作正常但是
onErrorResponse：错误：

HashMap<String, String> params = new HashMap<String, String>();
params.put("employeeId", "dd25ec65-e276-488b-92b1-a324a1d4cc18");
private void getData(){
    //Showing a progress dialog
    final ProgressDialog loading = ProgressDialog.show(this,"Loading Data", "Please wait...",false,false);

    //Creating a json obj request
    JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Config.DATA_URL,new JSONObject(params),
            new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            VolleyLog.v("Response:%n %s",response.toString());
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.e("Error: ", error.getMessage());
        }
    });

    //Creating request queue
    RequestQueue requestQueue = Volley.newRequestQueue(this);

    //Adding request to the queue
    requestQueue.add(jsonObjectRequest);
}

我建议像这样使用：

  private void getData(){
        //Showing a progress dialog
        final ProgressDialog loading = ProgressDialog.show(this,"Loading Data", "Please wait...",false,false);

        //Creating a json obj request
 StringRequest dataRequest = new StringRequest(Request.Method.POST,
                Config.DATA_URL, new Response.Listener<String>() {

            @Override
            public void onResponse(String response) {
                loading.dismiss();
                Log.v("Response",response.toString());

            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                loading.dismiss();
                Log.e("Error: ", error.getMessage());

            }
        }){
    @Override
                protected Map<String, String> getParams() throws AuthFailureError {
                    Map<String, String> sendMap = new HashMap<String, String>();
    sendMap.put("employeeId", "dd25ec65-e276-488b-92b1-a324a1d4cc18");

                    return sendMap;
                }

    };

        //Creating request queue
        RequestQueue requestQueue = Volley.newRequestQueue(this);

        //Adding request to the queue
        requestQueue.add(dataRequest);
    }

如果有任何错误，请告诉我.....
