我如何在android studio上使用klaxon从thingspeak中解析出json来获取字段值？

dependencies {
    implementation 'com.beust:klaxon:5.0.1'
}

import com.beust.klaxon.*

val url = "https://api.thingspeak.com/channels/your_channel_id/feeds.json?api_key=your_api_key"
val client = OkHttpClient()
val request = Request.Builder().url(url).build()
val response = client.newCall(request).execute()
val json = response.body()?.string()

val parser = Parser.default()
val stringBuilder = StringBuilder(json)
val jsonArr = parser.parse(stringBuilder) as JsonArray<JsonObject>

for (jsonObj in jsonArr) {
    val field1Value = jsonObj.string("field1")
    val field2Value = jsonObj.string("field2")
    // 获取其他字段值...
    
    // 在这里可以对获取到的字段值进行处理或展示
}
