retrofit2.响应体是null

Question

    Retrofit retrofit = new Retrofit.Builder().baseUrl(Api.Q_BASE)
            .addConverterFactory(GsonConverterFactory.create()).client(client).build();
    Api.ApiInter inter = retrofit.create(Api.ApiInter.class);
    Call<JSONObject> call = inter.getMovieData(sortType[0], Api.P_KEY);
    call.enqueue(new Callback<JSONObject>() {
        @Override
        public void onResponse(Call<JSONObject> call, Response<JSONObject> response) {
            /* */
        }

        @Override
        public void onFailure(Call<JSONObject> call, Throwable t) {
            Log.d(LOG_TAG, "failed to get response.");
        }
    });

public class Api {
    public static final String Q_BASE = "http://api.themoviedb.org/";
    public static final String Q_KEY = "api_key";
    public static final String Q_RESULT = "results";

    public static final String Q_VOTE_AVERAGE = "vote_average";
    public static final String P_KEY = "This is private key";
    public static final String REQUEST = "GET";

    public static final String I_BASE = "http://image.tmdb.org/";
    public static final String P_POSTER_SIZE = "w185";

    public interface ApiInter {
        @GET("3/movie/{sort}")
        Call<JSONObject> getMovieData(@Path("sort") String sort, @Query("api_key") String key);

        @GET("t/p/{size}/{url}")
        Call<Bitmap> getMoviePoster(@Path("size") String size, @Path("url") String url);
    }
}

当我调试我的应用程序时,response.body()始终仅重新启动"{}".如果我更改了Call的元素,则返回值将为null.我不知道原因.我想获得JSON数据.我怎么解决这个问题？我可以设置okhttp客户端吗？或更改Call的返回类型？请给我答案.

Answer 1

这是一个非常简单的错误.如果你有像我这样的问题,请检查这三件事.

1. 你的改装转换器是Gson.

2. 你的api接口方法返回 Call<JSONObjcet>

3. 请求成功,但response.body()只是"{}"

改造使用GsonConverter.所以我们需要在包中使用jsonObject com.google.gson.你必须JSONObject改为JsonObject
