Question

我正在使用具有以下命令的基于Python的Discord机器人

@client.command(name="Mine",
            description="Mine daily.",
            brief="Mine daily.",
            aliases=['mine', 'm'],
            pass_context=True)
@commands.cooldown(1, 30, commands.BucketType.user)
async def mine(ctx, arg):
   <content>

但是，当用户达到命令的30秒速率限制时，它将错误输出到python shell

Ignoring exception in command Mine
Traceback (most recent call last):
   File "C:\Users\raner\AppData\Local\Programs\Python\Python36\lib\site- 
      packages\discord\ext\commands\bot.py", line 846, in process_commands
      yield from command.invoke(ctx)
   File "C:\Users\raner\AppData\Local\Programs\Python\Python36\lib\site- 
      packages\discord\ext\commands\core.py", line 367, in invoke
      yield from self.prepare(ctx)
   File "C:\Users\raner\AppData\Local\Programs\Python\Python36\lib\site- 
      packages\discord\ext\commands\core.py", line 351, in prepare
      raise CommandOnCooldown(bucket, retry_after)
discord.ext.commands.errors.CommandOnCooldown: You are on cooldown. Try 
again in 28.58s

我想做的事情是获得剩余的冷却时间，然后将其放入可以与用户不和谐地说给用户的东西，例如“此命令受速率限制，请在28.58秒后重试”。

我在网上找不到很多帮助，其中大多数已经过时或似乎无法使用。

谢谢！

您需要为处理error handler错误并发送消息的命令编写CommandOnCooldown。

@mine.error
async def mine_error(error, ctx):
    if isinstance(error, commands.CommandOnCooldown):
        msg = 'This command is ratelimited, please try again in {:.2f}s'.format(error.retry_after)
        await client.send_message(ctx.message.channel, msg)
    else:
        raise error

discord.py僵尸程序获得命令的剩余冷却时间
