我有这个错误：

Volley: [8918] BasicNetwork.performRequest: Unexpected response code 403 for

我正在尝试连接到服务器，但我无法检索任何内容。当我在本地主机服务器中尝试它时，它运行良好。

我试图从GET请求发送一些身份验证标头,我尝试使用Volley JsonObjectRequest调用:

Map<String,String> params=new HashMap<String,String>();
        params.put("token","fghjbvjhnjjk");
        activity.showDialog();
        JsonObjectRequest req = new JsonObjectRequest(Request.Method.GET,url,
                new JSONObject(params), new Response.Listener<JSONObject>() {

            @Override
            public void onResponse(JSONObject response) {
                Log.d(tag, response.toString());
                activity.hideDialog();
                try {
                    activity.onRequestServed(response, code);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d(tag, "Error: " + error.getMessage());
                Log.e(tag, "Site Info Error: " + error.getMessage());
                Toast.makeText(activity.getApplicationContext(),
                        error.getMessage(), Toast.LENGTH_SHORT).show();
                activity.hideDialog();
                try {
                    activity.onRequestServed(null,code);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }); …
