问带有基元数组的json异常

EN

fun findAll(): ArrayList<User>? {
    val url = URL("http:///10.0.2.2:8080/employees")
    val connection = url.openConnection() as HttpURLConnection
    connection.setRequestProperty("Accept", "application/json");

    var users = arrayListOf<User>()
    (if (connection.responseCode == 200) connection.inputStream else connection.errorStream).use { stream ->
        BufferedReader(InputStreamReader(stream)).use { reader ->
            var line: String?
            val response = StringBuffer()

            while ((reader.readLine().also { line = it }) != null) {
                response.append(line)
            }

            
            val jsonArray = JSONArray(response)
            for (i in 0 until jsonArray.length()) {
                val user = jsonArray.getJSONObject(i)
            }
        }
    }

    return users
}

data class User(var id: Long?, var first: String?, var last: String?): Parcelable 

val jsonArray = JSONArray(response)
