Резюме: я пытаюсь получить данные из национальных парков (API), и у них есть JSON, у которого нет имени основного элемента. И кажется, что модификация смотрит на имя переменной для автоматического поиска элемента. Он не возвращает ошибку «Парки обязательных значений отсутствуют в $». У меня нет парков, но я вообще не ищу элемент парков. Я искал через stackoverflow, чтобы увидеть, если у кого-то есть подобная проблема и не нашел, поэтому я отправляю этот вопрос здесь.
Подробно: Вот json из API ...

Ниже приведен класс данных, который я написал:
data class NetworkParkContainer(val parks: List<NetworkPark>)
data class NetworkPark(
val data: List<Data>,
val limit: String,
val start: String,
val total: String
)
Вот код, который я вызвал для получения данных JSON:
interface ParksApiService {
companion object {
val API_KEY = "<my own api key value>"
}
@GET("parks")
suspend fun getParks(@Query("api_key") type: String, @Query("limit") limit: Int): NetworkParkContainer
}
Зачем искать Retrofit 2 ' парки? Ни в одном из моих классов данных нет «парков». Кажется, он смотрит на «парки» в:
data class NetworkParkContainer(val parks: List<NetworkPark>)
Как бы я сказал дооснащению, что я хочу все это так, как я написал класс данных NetworkPark, который даже не включает «парки»?
Вот путь API: https://developer.nps.gov/api/v1/parks?api_key= & limit = 1
Мой базовый URL-адрес https://developer.nps.gov/api/v1/
Так что мой @GET - парки поэтому должно получиться так: https://developer.nps.gov/api/v1/parks?api_key= & limit = 1
