如何在Kotlin中处理500错误并使用Retrofit2显示详细信息？

val retrofit = Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .build()

val errorHandler = retrofit.responseBodyConverter<ErrorResponse>(ErrorResponse::class.java, arrayOfNulls<Annotation>(0))

val service = retrofit.create(ApiService::class.java)

data class ErrorResponse(val code: Int, val message: String)

interface ApiService {
    @GET("your_endpoint")
    fun getData(): Call<DataResponse>
}

service.getData().enqueue(object : Callback<DataResponse> {
    override fun onResponse(call: Call<DataResponse>, response: Response<DataResponse>) {
        // 处理成功响应
    }

    override fun onFailure(call: Call<DataResponse>, t: Throwable) {
        val errorResponse = errorHandler.convert(response.errorBody())
        val errorMessage = errorResponse?.message ?: "Unknown error"
        // 处理错误响应
    }
})
