无效的API密钥或未经批准的应用程序，从trakt-tv获取数据

Question

我遇到了以下问题：我需要从trakt-tv获得流行电影的列表。为此，我创建了以下类：

public class MoviesListDownload extends AsyncTask<Void, Void, ArrayList<Movie>> {

    @Override
    protected ArrayList<Movie> doInBackground(Void... voids) {
        ArrayList<Movie> moviesList = new ArrayList<>();

        String baseUrl = "https://api.trakt.tv/";

        Retrofit.Builder builder = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .addConverterFactory(GsonConverterFactory.create());

        OkHttpClient.Builder httpClient = new OkHttpClient.Builder()
                .connectTimeout(10, TimeUnit.SECONDS)
                .writeTimeout(10, TimeUnit.SECONDS)
                .readTimeout(10, TimeUnit.SECONDS);

        httpClient.addInterceptor(chain -> {
            Request original = chain.request();

            Request.Builder requestBuilder = original
                    .newBuilder()
                    .header("Content-Type", "application/json")
                    .header("trakt-api-version", "2")
                    .header("trakt-api-key", [auth_key]);
Request request = requestBuilder.build();
            return chain.proceed(request);
        });

        Retrofit retrofit = builder.build();

        APIService apiService = retrofit.create(APIService.class);
        Call<List<Movie>> moviesListCall = apiService.getMovies();

        try {
            Response<List<Movie>> result = moviesListCall.execute();
            Log.i("ResCode",result.code()+"");
            if (result.code() == 200) {
                moviesList.addAll(Objects.requireNonNull(result.body()));
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        return moviesList;
    }

}

这是我需要获取的JSON：

            }
        }
    }

这是我用来获取JSON的方法：

@GET ("movies/trending")
Call<List<Movie>> getMovies();

Movie类仅包含字段title，该字段具有注释SerializedName ("title")。

当然，我知道Retrofit应该以另一种方式构建，作为单例对象，但是在这种情况下没有必要。当我运行这段代码时，我得到response.code() = 403的含义，因为它是蜂房403 Forbidden - invalid API key or unapproved app。但是我不明白，为什么会这样，就像我打开个人资料时写的那样，它批准的我的应用程序和密钥是有效的，并且与我使用的相同。那怎么了也许其他地方有错误？
