Question

我创建了一个Volley JsonObjectRequest，它向我的REST API发出HTTP请求。但是在打电话之后，它没有响应任何Json。

     String JSON_URL = "http://192.168.10.136:8000/api/vehicle";
     JsonObjectRequest jsonObjectRequest=new JsonObjectRequest(JSON_URL,null,new Response.Listener<JSONObject>(){
        @Override
        public void onResponse(JSONObject response){
            try {
                JSONArray vehicles = response.getJSONArray("vehicles");
                for (int i=0;i<vehicles.length();i++)
                {
                    JSONObject vehicle=vehicles.getJSONObject(i);
                    if(vehicle.getString("type")=="Taxi") {
                        TaxiList sr1 = new TaxiList();
                        sr1.setName(vehicle.getString("name"));
                        sr1.setPhone(vehicle.getString("phone"));
                        results.add(sr1);
                    }
                }
            }catch (JSONException e){
                e.printStackTrace();
            }
        }
    },new Response.ErrorListener(){
        @Override
        public void onErrorResponse(VolleyError error){

        }
    });

    RequestQueue requestQueue = Volley.newRequestQueue(getContext());
    requestQueue.add(jsonObjectRequest);

我的REST API是使用Laravel 5.2构建的

执行期间没有显示错误。执行后，日志窗口包含以下消息：

我需要帮助来解决这个问题

你必须指定你想要使用URL做什么，无论是Get请求还是Post请求。

JsonObjectRequest jsonObjectRequest=new JsonObjectRequest(Request.Method.GET,JSON_URL,new Response.Listener<JSONObject>(
{
});

没有得到Android中REST API的响应
