解析包含对象的API数据(Klaxon) (Kotlin)

Question

我有API响应，其中包含对象(图形)

[
    {
        "code": 200,
        "status": "OK",
        "FirstDay": "2019-11-18",
        "LastDay": "2019-11-24",
        "graphic": {
            "2019-11-23": [
                {
                    "godzinaStart": "08:30",
                    "godzinaStop": "10:00",
                    "przedmiot": "Matematyka dyskretna",
                    "sala": "32AK8",
                    "nauczyciel": "xxx",
                    "grupy": "1K131; 1K132; 1K133; 1K134; 1K135; 2K131",
                    "typ": "wykład"
                },
            ],
            "2019-11-24": [
                {
                    "godzinaStart": "08:30",
                    "godzinaStop": "10:00",
                    "przedmiot": "Podstawy informatyki",
                    "sala": "308K",
                    "nauczyciel": "xxx",
                    "grupy": "1K131",
                    "typ": "laboratorium"
                },
            ]
        }
    }
]

我必须将这个JSON解析为Kotlin中的对象。所以我用参数做了课

class GraphicAPIResponse(
    var code: Int,
    var status: String,
    var errorMessage: String = "",
    var FirstDay: String = "",
    var LastDay: String = "",
    var graphic: JsonObject? = null OR var graphic: JsonArray<Any>? = null (I tried both)
)

我用这个函数来解析数据

val responeAPI = Klaxon().parseArray<GraphicAPIResponse>(response)

图形为JsonObiect类型时，应用程序抛出错误

I/System.out: ERROR -> Unable to instantiate JsonObject with parameters []

当图形是JsonArray<Any>类型时，下面是错误

I/System.out: ERROR -> Unable to instantiate GraphicAPIResponse with parameters [LastDay: 2019-11-24, code: 200, status: OK, graphic: java.lang.Object@aef265a, FirstDay: 2019-11-18]

我正试着从两个小时内解决这个问题。有人能帮帮我吗？

谢谢你阿列克西·罗曼诺夫

那有帮助

为嵌套对象定义类型：

class Lesson(val godzinaStart: String, val godzinaStop: String, ...)

并在GraphicAPIResponse中使用

class GraphicAPIResponse(
    var code: Int,
    var status: String,
    var errorMessage: String = "",
    var FirstDay: String = "",
    var LastDay: String = "",
    var graphic: Map<String, Lesson> = mapOf()
)

(老实说，我希望JsonObject也能工作)
