我需要解析下面的JSON负载：

{
  "status": "success",
  "data": {
    "stats": {
      "total": 11812,
      "offset": 0,
      "limit": 50,
      "order": "desc",
      "base": "USD",
      "totalMarkets": 77573,
      "totalExchanges": 372,
      "totalMarketCap": 1692792022714.2244,
      "total24hVolume": 78345365115.11235
    },
    "base": {
      "symbol": "USD",
      "sign": "$"
    },
    "coins": [
      {
        "id": 1,
        "uuid": "Qwsogvtv82FCd",
        "slug": "bitcoin-btc",
        "symbol": "BTC",
        "name": "Bitcoin",
   ...
}

我对“硬币”的价值有一个问题：

fun fetchJson() {
    val url = "https://api.coinranking.com/v1/public/coins"
    val request = Request.Builder().url(url).build()

    val client = OkHttpClient()
    client.newCall(request).enqueue(object: okhttp3.Callback {
        override fun onFailure(call: okhttp3.Call, e: IOException) {
            println("Failed")
        }

        override fun onResponse(call: okhttp3.Call, response: okhttp3.Response) {
            val body = response?.body?.string()
            println(body)

            val gson = GsonBuilder().create()
            val coins = gson.fromJson(body, coinrank::class.java)
            println("THESE ARE THE COINS : " +coins)
        }
    })
}
}

数据模型：

class coinrank(val status: String?, val data: Array<dataR>?)

class dataR (val coins: List<justCoin>?)

class justCoin (
    val id: Int?,
    val name: String?,
    val description: String?,
    val slug: String?,
    val symbol: String?,
    val iconUrl: String?
        )

发生错误：
导致错误的原因：java.lang.路径$.data的第1行第29列应为开始_ARRAY，但实际上是BEGIN_OBJECT
在线上：val coins = gson.fromJson(body, coinrank::class.java)个
我尝试将val data: Array<dataR>?更改为val data: JSONObject“，但我仍然无法找到访问这些值的方法，有人能帮助我吗？
