给定游戏的玩家列表是未知的（有些游戏是40，有时是42，它会改变）。如何将这些数据表示为Kotlin类？我尝试将其表示为ArrayList，但是在对其进行解析时出现错误Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 111 column 18 path $.gameData.players

我知道这意味着它期待一个数组（我定义的数组），而是获得了JSON对象ID8470607，但是由于ID一直都是不同的，并且播放器列表的长度每次都会不同，我无法像其他班级那样在字段中进行硬编码。那么我应该如何将其表示为数据类呢？

这是我目前拥有的：

data class GameData (
    val game: GameInfo,
    val datetime: DateTime,
    val status: GameStatus,
    val teams: GameTeams,
    val players: ArrayList<Player>,
    val venue: GameVenue
)

谢谢。

问题是您没有收到列表，示例中定义的destroyed() { Event.$off('category.save'); Event.$off('category.exit'); }是地图。如果您想解析上面显示的示例，则GameData类需要如下所示：

players

这样，您将拥有一个玩家地图（对于此特定示例，您将必须按键data class GameData ( val game: GameInfo, val datetime: DateTime, val status: GameStatus, val teams: GameTeams, val players: Map<String,Player>, val venue: GameVenue )和ID8470607）
