如何在Kotlin中模拟URL连接？

import java.net.HttpURLConnection
import java.net.URL
import java.io.BufferedReader
import java.io.InputStreamReader

val url = URL("https://www.example.com")

val connection = url.openConnection() as HttpURLConnection

connection.requestMethod = "GET"

connection.setRequestProperty("User-Agent", "Mozilla/5.0")

val responseCode = connection.responseCode

if (responseCode == HttpURLConnection.HTTP_OK) {
    // 请求成功，读取响应内容
    val inputStream = connection.inputStream
    val reader = BufferedReader(InputStreamReader(inputStream))
    val response = StringBuilder()
    var line: String?
    while (reader.readLine().also { line = it } != null) {
        response.append(line)
    }
    reader.close()
    inputStream.close()

    // 处理响应内容
    println(response.toString())
} else {
    // 请求失败，处理错误
    println("请求失败，错误码：$responseCode")
}
