android - Android: Kotlin - Retrofit2 - Moshi

问题描述

我正在尝试使用此 API 请求获取游戏列表。 https://steamspy.com/api.php?request=top100forever

但是我相信我的问题是所有游戏都在另一个东西里面，只有 appid。这就是响应的样子

{
  "10": {
    "appid": 10,
    "name": "Counter-Strike",
    "developer": "Valve",
    "publisher": "Valve",
    "score_rank": "",
    "positive": 143404,
    "negative": 3739,
    "userscore": 0,
    "owners": "20,000,000 .. 50,000,000",
    "average_forever": 9671,
    "average_2weeks": 815,
    "median_forever": 287,
    "median_2weeks": 925,
    "price": "99",
    "initialprice": "999",
    "discount": "90"
  },
  "30": {
    "appid": 30,
    "name": "Day of Defeat",
    "developer": "Valve",
    "publisher": "Valve",
    "score_rank": "",
    "positive": 3885,
    "negative": 463,
    "userscore": 0,
    "owners": "5,000,000 .. 10,000,000",
    "average_forever": 259,
    "average_2weeks": 0,
    "median_forever": 33,
    "median_2weeks": 0,
    "price": "49",
    "initialprice": "499",
    "discount": "90"
  },
  ....
}

我的api服务：

private const val BASE_URL_GAMES = "https://steamspy.com/"

private val moshi = Moshi.Builder()
    //.add(ResponseGetGamesAdapter())
    .add(KotlinJsonAdapterFactory())
    .build()

//OkhttpClient for building http request url
private val tmdbClient = OkHttpClient().newBuilder()
    .build()

private val retrofit = Retrofit.Builder()
    .client(tmdbClient)
    .addConverterFactory(MoshiConverterFactory.create(moshi))
    .addCallAdapterFactory(CoroutineCallAdapterFactory())
    .baseUrl(BASE_URL_GAMES)
    .build()


interface GameApiService{
    @GET("api.php?request=top100forever")
    fun getTop100(): Deferred<List<Game>>

}



object GameApi {
    val retrofitService: GameApiService by lazy {
        retrofit.create(GameApiService::class.java)
    }
}

视图模型

enum class GameApiStatus { LOADING, ERROR, DONE }

class GameOverviewViewModel : ViewModel() {
    // TODO: Implement the
    private val _response = MutableLiveData<String>()
    private val _status = MutableLiveData<GameApiStatus>()

    //private var gameRepository: GameRepository = GameRepository()

    // The external immutable LiveData for the response String
    val response: LiveData<GameApiStatus>
        get() = _status

    private val _properties = MutableLiveData<List<Game>>()
    val properties: LiveData<List<Game>>
        get() = _properties

    // Create a Coroutine scope using a job to be able to cancel when needed
    private var viewModelJob = Job()

    // the Coroutine runs using the Main (UI) dispatcher
    private val coroutineScope = CoroutineScope(viewModelJob + Dispatchers.Main )

    init {
        getTop100()
    }

    private fun getTop100() {
        coroutineScope.launch {
            // Get the Deferred object for our Retrofit request
            var getPropertiesDeferred = GameApi.retrofitService.getTop100()
            try {
                // Await the completion of our Retrofit request
                var listResult = getPropertiesDeferred.await()
                _status.value = GameApiStatus.DONE
                _properties.value = listResult
            } catch (e: Exception) {
                val error = e.message
                _status.value = GameApiStatus.ERROR
                _properties.value = ArrayList()
            }
        }
    }

    /**
     * When the [ViewModel] is finished, we cancel our coroutine [viewModelJob], which tells the
     * Retrofit service to stop.
     */
    override fun onCleared() {
        super.onCleared()
        viewModelJob.cancel()
    }
}

游戏模型

data class Game(
    //var id:Int,
    @field:Json(name = "appid")
    var appid:Int,
    @field:Json(name = "name")
    var name:String
    //var desc:String
)

在这一点上，我一直在苦苦挣扎，我可能在路上弄坏了更多东西，哈哈，我认为我需要某种适配器，但我绝对一无所知。试图尽可能地贴近我们课程中的做法，但在这一点上，我会采取任何工作方式：D
