通过局域网发送请求？

Question

我正在尝试使用我的命令（例如 192.168.0.2/toggle）执行一个 ip，它会将命令发送到我拥有的设备。但是，我无法使用命令本身执行 ip。我的代码如下。

var i = 1
        LockButton.setOnClickListener {
            if (i == 1) {
                Toast.makeText(this@MainActivity, "Locked!", Toast.LENGTH_LONG).show()
                val connection: URLConnection = URL("Https://" + ipcomm2).openConnection()
                connection.connect()
                i = 0
            }
            else if (i == 0) {
                Toast.makeText(this@MainActivity, "MUnlocked!", Toast.LENGTH_LONG).show()
                val connection2: URLConnection = URL("Https://" + ipcomm2).openConnection()
                connection2.connect()
                i = 1
            }
        }

但是，由于我对 Kotlin 编码相对较新，我不太了解执行 URL，因此出现错误

第31行就是这一行

val connection: URLConnection = URL("Https://" + ipcomm2).openConnection()

非常感谢任何帮助。谢谢
