字段的Kotlin序列化,可以是字符串或字符串数组

有 an example covering a similar case in the documentation User s、 如果要将其解析为单个 Person ,大概是

@Serializable
data class Person(
    @Serializable(with=StringListSerializer::class)
    val strings: List<String>)

object StringListSerializer :
    JsonTransformingSerializer<List<String>>(serializer<List<String>()) {
    // If response is not an array, then it is a single object that should be wrapped into the array
    override fun transformDeserialize(element: JsonElement): JsonElement =
        if (element !is JsonArray) JsonArray(listOf(element)) else element
}
