Question

Все

Я пытался ответить на любой вопрос, который нашел в stackoverflow, чтобы решить мою проблему с загрузкой некоторых данных из объекта json, который содержит сотни вложенных объектов. Для начала взгляните на объект Json ниже.

Мне просто нужны некоторые данные из этого json, такие как идентификатор, имя, описание и путь, который внутри другого объекта. Они находятся в массиве, который называется «result».

Я работаю над android проектом с kotlin

Вот мои классы данных

data class Character(var id: String,var name: String,var description: String,var path:tring)

data class CharacterResult(var characters: List<Character>)

Класс Character будет содержать все эти атрибуты, а CharacterResult будет иметь список Character.

Это мой интерфейс

интерфейс CharacterService {

@GET("/v1/public/characters")
fun getCharacters(@QueryMap params:Map<String,String>) : Call<CharacterResult>

} ​​

Это мой сервис

класса ServiceBuilder {

companion object Factory {

    var url: String = "https://gateway.marvel.com";

    fun <S> buildService(clazz: Class<S>) : S {
        val retrofit = Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create())
            .baseUrl(url)
            .build()
        return retrofit.create(clazz);
    }
}

}

А вот MainActivity, который соберет все эти вещи вместе, чтобы получить результаты

class MainActivity: AppCompatActivity () {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    setSupportActionBar(toolbar)

    var task: CharacterService = ServiceBuilder.buildService(CharacterService::class.java)

    var map = mapOf("my params") the params were passed fine don't worry abou that.

    var call: Call<CharacterResult> = task.getCharacters(map);

    call.enqueue(CallBackImpl())
}

class CallBackImpl() : Callback<CharacterResult> {

    var debug: String = "TAG"

    override fun onFailure(call: Call<CharacterResult>, t: Throwable) {

        var result = call.request().body().toString();

        Log.d(debug,result)
    }

    override fun onResponse(call: Call<CharacterResult>, response: response<CharacterResult>) {

        if(response.isSuccessful){
            var c = response.body();
            print(c);
        }
    }



}

Ответ в порядке, что означает, что был вызван onResponse, но список символов пуст. API Gson не загружал объекты. Я что-то пропустил ? Может ли кто-нибудь сказать мне, что я делаю не так? Я был бы очень рад. Большое спасибо за ваши усилия и время, чтобы ответить на этот вопрос.
