我有一个用you-get的方法，不过不是很优雅，抛砖引玉吧

object YougetCommand: SimpleCommand(
    owner = PluginMain,
    "youget",
    "you-get",
    description = "you-get"
) {
    private var cnt = 0
    private var lock = Any()
    private fun getNo(): Int {
        synchronized(lock) {
            cnt += 1
            return cnt
        }
    }
    private fun get(process: Process): String {
        return String(process.inputStream.readNBytes(process.inputStream.available()))
    }
    @Handler
    suspend fun CommandSenderOnMessage<GroupMessageEvent>.run(arg: String, refresh: Long? = null) {
        val cookie =
            if (arg.contains("bilibili")) {
                "/home/michael/cookies/bilibili/youget.txt"
            } else {
                null
            }
        val no = getNo()
        var cmdline = "you-get $arg -O /tmp/mirai-$no"
        if (cookie != null) {
            cmdline += " -c $cookie"
        }
        val f = File("/tmp/").listFiles { _, name -> name.contains("mirai-$no") }.firstOrNull()
        if (f != null) {
            f.delete()
        }
        val process = ProcessBuilder(cmdline.split(' ')).start()
        var title = "untitled"
        var s = ""
        while (!process.waitFor(1, TimeUnit.SECONDS)) {
            s += get(process)
            if (s.contains("Downloading ")) {
                fromEvent.subject.sendMessage(s.substring(0, s.lastIndexOf("\n")))
                val titleLine = s.split("\n")[1]
                title = titleLine.substring(titleLine.lastIndexOf(' ') + 1)
                "\\/:*?\"<>|".forEach {
                    title = title.replace(it, '_')
                }
                s = s.substring(s.lastIndexOf("\n") + 1)
            }
        }
        if (refresh != null) {
            do {
                s += get(process)
                val pos = s.lastIndexOf('\r')
                if (pos != -1) {
                    val sub = s.substring(0, pos)
                    val pos2 = sub.lastIndexOf('\r')
                    s = s.substring(pos2)
                    fromEvent.subject.sendMessage(sub.substring( pos2 + 1))
                }
            } while(!process.waitFor(refresh, TimeUnit.SECONDS))
        } else {
            while(!process.waitFor(1, TimeUnit.SECONDS));
        }
        val video = File("/tmp/").listFiles { _, name -> name.contains("mirai-$no") }.firstOrNull()
        if (video != null) {
            val ext = video.extension
            // fromEvent.subject.sendMessage("Uploading ...")
            println(video.length())
            fromEvent.group.files.uploadNewFile(
                "/$title.$ext",
                video.toExternalResource(ext).toAutoCloseable(),
                object : ProgressionCallback<AbsoluteFile, Long> {
                    var last = 0
                    val tot = video.length()
                }
            )
            // video.delete()
        } else {
            fromEvent.subject.sendMessage("file not found!")
        }
