无法从 000webhost.com 访问 json 文件

Question

我正在使用 000webhost.com 来托管我的文件，我可以通过网络浏览器访问它们，是否有任何我应该知道的虚拟主机上的设置可以让我的文件可供我的 android 应用程序。

我无法通过 android 访问 json 文件甚至图像文件夹，当执行改造的 onFailure() 方法时，printStackTrace 方法说：

这里是我使用的 http 地址：

public static final String ENDPOINT =
            "http://services.hanselandpetal.com";
    public static final String ENDPOINT2 =
            "http://ajay_pyaraka.site88.net";

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(ENDPOINT2)
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        FlowersAPI service = retrofit.create(FlowersAPI.class);
        Call<List<Flower>> call = service.getFeed2();

        call.enqueue(new Callback<List<Flower>>() {
            @Override
            public void onResponse(Call<List<Flower>> call, Response<List<Flower>> response) {
                if (response.isSuccessful()) {
                    flowerList = response.body();
                    updateDisplay();
                }

            }

            @Override
            public void onFailure(Call<List<Flower>> call, Throwable t) {
                Toast.makeText(MainActivity.this, "Failure", Toast.LENGTH_SHORT).show();
                t.printStackTrace();
            }

        });

我能够从第一个 var ENDPOINT 获得，但不能从第二个 ENDPOINT2
