E / Volley：[33049] BasicNetwork.performRequest：意外的响应代码404

Question

我正在使用RecyclerView来显示从DB获取的数据。它没有用。

  

获得错误E / Volley：[33049] BasicNetwork.performRequest：意外的响应代码404.

需要在下面解析响应： -

[
{
"code":"23232",
"desc":"ddddjdkdkcn",
"price":[
"price"
]
},
{
"code":"de33fd",
"desc":"ddds",
"price":[
"price"
]
}
]

  public class Background {
    String url = "http://192.168.0.103/android_fetch.php";
    Context context;
    ArrayList<Data> arrayList = new ArrayList<>();

    public Background(Context context) {
        this.context = context;
    }
    public ArrayList<Data> getList() {
        JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.GET, url, (String) null,
                new Response.Listener<JSONArray>() {
                    @Override
                    public void onResponse(JSONArray response) {
                        int count = 0;
                        while (count < response.length()) {
                            try {
                                JSONObject jsonObject = response.getJSONObject(count);
                                Data data = new Data(jsonObject.getString("code"), jsonObject.getString("desc"), jsonObject.getString("price"));
                                arrayList.add(data);
                                count++;
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(context, "Error", Toast.LENGTH_SHORT).show();
                error.printStackTrace();
            }
        });
        MySingleton.getInstance(context).addToRequestque(jsonArrayRequest);
       return arrayList;
    }
}
