Question

这是我使用Discord机器人播放音乐的代码，但是我必须手动输入网址，但我想不出添加搜索功能的方法。

要播放音乐，我要在url中下载音频，然后使用ffmpeg播放音频。如果您听不懂我会很乐意回答。

@client.command(pass_context=True)
async def play(ctx, url: str):

    def check_queue():
        Queue_infile = os.path.isdir("./Queue")
        if Queue_infile is True:
            DIR = os.path.abspath(os.path.realpath("Queue"))
            length = len(os.listdir(DIR))
            still_q = length - 1
            try:
                first_file = os.listdir(DIR)[0]
            except:
                print("No more queued song(s)\n")
                queues.clear()
                return
            main_location = os.path.dirname(os.path.realpath(__file__))
            song_path = os.path.abspath(os.path.realpath("Queue") + "\\" + first_file)
            if length != 0:
                print("Song done, playing next queued\n")
                print(f"Songs still in queue: {still_q}")
                song_there = os.path.isfile("song.mp3")

使用Youtube API的搜索功能在YouTube上进行搜索。它还会返回视频ID，然后您可以将其转换为链接。但是，为此创建另一个python文件。希望这对您有帮助

在discord.py音乐漫游器中添加搜索功能
