如何从Kotlin / Java中的网站链接中获取音频文件的长度？

import java.io.BufferedInputStream;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
import javax.sound.sampled.AudioFileFormat;
import javax.sound.sampled.AudioSystem;

fun getAudioFileLengthFromUrl(urlString: String): Long {
    var connection: HttpURLConnection? = null
    var inputStream: BufferedInputStream? = null
    try {
        val url = URL(urlString)
        connection = url.openConnection() as HttpURLConnection
        connection.setRequestProperty("Range", "bytes=0-1") // 请求音频文件的前两个字节
        connection.connect()

        inputStream = BufferedInputStream(connection.inputStream)
        val audioInputStream = AudioSystem.getAudioInputStream(inputStream)
        val audioFileFormat = AudioSystem.getAudioFileFormat(audioInputStream)
        val audioFileLength = audioFileFormat.properties[AudioSystem.NOT_SPECIFIED] as Long

        return audioFileLength
    } catch (e: Exception) {
        e.printStackTrace()
    } finally {
        inputStream?.close()
        connection?.disconnect()
    }
    return -1
}

fun main() {
    val audioUrl = "https://example.com/audio.mp3"
    val audioFileLength = getAudioFileLengthFromUrl(audioUrl)
    if (audioFileLength != -1L) {
        println("音频文件长度为：$audioFileLength 字节")
    } else {
        println("无法获取音频文件长度")
    }
}
