Question

我正在尝试从IGDB api发出请求，但出现以下错误：

java.lang.RuntimeException: Unable to start activity ComponentInfo{leandro.com.gameloversapp/leandro.com.gameloversapp.Presentation.Main.MainActivity}: java.lang.IllegalArgumentException: URL query string "fields={fields}&filter[release_dates.platform][any]={platform}" must not have replace block. For dynamic query parameters use @Query.

这些是ny类：

public interface IGameApi {

    @GET("/games/?fields=name,cover&filter[release_dates.platform][any]={platform}")
    @Headers("Accept:application/json")
    Call<List<Games>> getGameByPlatform(@Query("platform") int platform, @Header("user-key") String key);
}

GameServer.java

public class GameServer {

    private static IGameApi iGameApi;
    private static GameServer gameServer;
    Context context;


    public GameServer(Context mContext) {
        this.context = mContext;
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(context.getString(R.string.base_url))
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        iGameApi = retrofit.create(IGameApi.class);
    }

    public static GameServer getInstance(Context context){
        if(gameServer == null){
            gameServer = new GameServer(context);
        }
        return gameServer;
    }

    public void getGameByPlatform(int platform,String user_key, Callback<List<Games>> callback){
        Call<List<Games>> gamesCall = iGameApi.getGameByPlatform(platform, user_key);
        gamesCall.enqueue(callback);
    }
}

该请求在邮递员申请中有效。

https://api-endpoint.igdb.com/games/?fields=name,cover&filter[release_dates.platform][any]=4

有人可以帮我吗？

Answer 1

尝试一下

@GET("/games/?fields=name,cover")
    @Headers("Accept:application/json")
    Call<List<Games>> getGameByPlatform(@Query("filter[release_dates.platform][any]") int platform, @Header("user-key") String key);

Answer 2

使用@Path的{{1}}实例

@Query

改进：URL查询字符串不能包含replace块
