我将JSON的主体返回到以下内容，但它一直崩溃。

val body = response.body!!.string()
                         println(body)
                         val gson = GsonBuilder().create()
                         val nowplayingFeed = gson.fromJson(body, NowPlayingJson::class.java)

它的本意是召唤

//NOW PLAYING DATA
class NowPlayingJson(val data: List<DataP>)

class DataP(val track: List<NowPlayingTrack>)

class NowPlayingTrack(val artist: String, val title: String, val imageurl: String, val type: String, val url:String)

但是由于某种原因，NowPlayingJson导致文件崩溃。

val nowplayingFeed = gson.fromJson(body, DataP::class.java)

它不会崩溃，但加载空，因为它无法读取轨道，因为它需要先读取数据。
JSON格式

{"data":[{"track":{"artist":"COEO","title":"Cabrio Mango (Original Mix)","imageurl":"https://storage.googleapis.com/ad-system/AdStichr-Logo.png","url":"https://www.adstichr.com/","type":"S"}}]}
