android graphQL apollo

我正在使用apollo-GraphQL进行API响应 . 我在Interceptor类中设置了令牌 . 在主要活动中，我正在使用apolloClient，我在其中传递查询以获取数据 .

我从拦截器类获得API响应但没有得到查询响应 .

public class HttpInterceptor implements Interceptor {

    @Override public Response intercept(Interceptor.Chain chain) throws IOException {

        java.util.logging.Logger logger = java.util.logging.Logger.getLogger("okhttp");
        String BASE_URL = "url_example.json";
        Response response = null;
        Request request = chain.request();

        request =chain.request();

        request = request.newBuilder()
                .url(BASE_URL)
                .header("token_key", "token_value")
                .build();

        long t1 = System.nanoTime();

        logger.info(String.format("Sending request %s on %s%n%s",
                request.url(), chain.connection(), request.headers()));
        response = chain.proceed(request);

        long t2 = System.nanoTime();

        logger.info(String.format("Received response for %s in %.1fms%n%s",
                response.request().url(), (t2 - t1) / 1e6d, response.headers()));
        return response;
    }

应用类代码：

private static final String BASE_URL = "url_example.json";
private ApolloClient apolloClient;

@Override public void onCreate() {
    super.onCreate();

    OkHttpClient okHttpClient  = new OkHttpClient.Builder()
            .addInterceptor(new HttpInterceptor())
            .build();

    apolloClient = ApolloClient.builder()
            .serverUrl(BASE_URL)
            .okHttpClient(okHttpClient)
            .build();
}

public ApolloClient apolloClient() {
    return apolloClient;
}

代码或MainActivity：

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        application = (SampleApplication) getApplication();

        content = (ViewGroup) findViewById(R.id.rl_content_holder);
        progressBar = (ProgressBar) findViewById(R.id.loading_bar);
        RecyclerView collectionRecyclerView = (RecyclerView) findViewById(R.id.rv_collection_list);
        mCollectionAdapter = new CollectionAdapter(this);
        collectionRecyclerView.setAdapter(mCollectionAdapter);
        collectionRecyclerView.setLayoutManager(new LinearLayoutManager(this));

        fetchCollection();
    }

    ApolloCall.Callback<ShopifyCollections.Data> mDataCallback =
            new ApolloCall.Callback<ShopifyCollections.Data>() {
        @Override
        public void onResponse(@Nonnull com.apollographql.apollo.api.Response<ShopifyCollections.Data> response) {
            Log.i("Shopify CallBack",response.toString());
        }

        @Override
        public void onFailure(@Nonnull ApolloException e) {
            Log.e(TAG, e.getMessage(), e);

        }
    };

    public  void fetchCollection(){

        mHttpClient = new OkHttpClient.Builder()
                .addInterceptor(new HttpInterceptor())
                .build();
        ShopifyCollections collectionQuery = ShopifyCollections.builder()
                .limit(250)
                .build();
        collectionCall = application.apolloClient().newCall(collectionQuery);
        collectionCall.enqueue(mDataCallback);
}

查询：

query ShopifyCollections($limit: Int!){
    shop{
        name
        collections(first: $limit)
{
            edges{
                node{
                    title
                    id
                  image{
                    src
                  }
                }
            }
        }
    }
}
