Android Clean MVVM 架构中的 API 响应处理

我已经使用Clean Architecture构建了应用程序，现在我计划将网络层验证添加到其中.

下面是我如何在我的应用程序中实现这一点的代码.

interface JokeApi {
    @GET("joke/Any")
    suspend fun getJoke(): Response<JokeResponseDto>
}

class JokeRepositoryImpl @Inject constructor(private val jokeApi: JokeApi) : JokeRepository {
    override suspend fun getJoke(): NetworkResponse<JokeResponse> {
        return handleApiResponse { jokeApi.getJoke() }
    }
}

• HandleApiResponse函数返回类型为NetworkResponse<JokeResponseDto>

suspend fun <T> handleApiResponse(execute: suspend () -> Response<T>): NetworkResponse<T> {
    return try {
        val response = execute()
        val body = response.body()
        if (response.isSuccessful && body != null) {
            NetworkResponse.Success(data = body)
        } else {
            NetworkResponse.Error(errorMessage = response.message())
        }
    } catch (exception: HttpException) {
        NetworkResponse.Error(errorMessage = exception.localizedMessage)
    } catch (throwable: Throwable) {
        NetworkResponse.Exception(throwable = throwable)
    }
}

sealed class NetworkResponse<T>(
    val data: T? = null,
    val errorMessage: String? = null,
    val exception: Throwable? = null,
) {
    class Success<T>(data: T) : NetworkResponse<T>(data = data)
    class Error<T>(errorMessage: String?) : NetworkResponse<T>(errorMessage = errorMessage)
    class Exception<T>(throwable: Throwable) : NetworkResponse<T>(exception = throwable)
}

在这种情况下，问题是改进返回JokeResponseDto响应对象，其中JokeRepositoryImpl预期JokeResponse的AS getJoke函数在此代码mapping中的情况下是有效的.

我try 在handleApiResponse方法中添加映射，因为它是泛型类型，所以没有过多考虑实现.

下面是我如何try 将响应转换为另一个仅具有必要细节的对象.

class JokeResponseMapper : Mapper<JokeResponseDto, JokeResponse> {
    override fun mapFrom(from: JokeResponseDto): JokeResponse {
        return JokeResponse(
            error = from.error,
            type = from.type.orEmpty(),
            setUp = from.type,
            joke = from.joke,
        )
    }
}

interface Mapper<F, T> {
    fun mapFrom(from: F): T
}

任何代码方面的帮助都将不胜感激.
