### 问题描述
*简要描述您碰到的问题。*
解析json
{"code":"000000","msg":{"data":[{"result":0.1419,"currencyT":"USD","currencyF_Name":"人民币","currencyF":"CNY","exchange":0.1419,"updateTime":"2025-06-16 19:55:00","currencyFD":"1","currencyT_Name":"美元"},{"result":7.0473,"currencyT":"CNY","currencyF_Name":"美元","currencyF":"USD","exchange":7.0473,"updateTime":"2025-06-16 19:55:00","currencyFD":"1","currencyT_Name":"人民币"}],"form":{"result":7.0473,"currencyT":"CNY","currencyF_Name":"美元","currencyF":"USD","exchange":7.0473,"updateTime":"2025-06-16 19:55:00","currencyFD":"1","currencyT_Name":"人民币"},"to":{"result":0.1419,"currencyT":"USD","currencyF_Name":"人民币","currencyF":"CNY","exchange":0.1419,"updateTime":"2025-06-16 19:55:00","currencyFD":"1","currencyT_Name":"美元"},"key":"USD"}}

解析方法
val jsonObject = JSON.parseObject(body)
val msgJSONObject = jsonObject.getJSONObject("msg")
val form = Gson().fromJson(
msgJSONObject.getString("form"),
ExchangeBean::class.java
)
val to = Gson().fromJson(
msgJSONObject.getString("to"),
ExchangeBean::class.java
)
val exchangeBeans: MutableList = ArrayList()
val dataArray = msgJSONObject.getJSONArray("data")
for (i in 0 until dataArray.size) {
val exchangeBean = Gson().fromJson(
dataArray.getString(i),
ExchangeBean::class.java
)
exchangeBeans.add(exchangeBean)
}

val exchangeDataBean = ExchangeDataBean(
exchangeBeans,
form,
msgJSONObject.getString("key"),
to
)
