問題描述
如果用戶鍵入 /foo 并且該命令不存在，我如何發(fā)送消息說該命令不存在"?
If user types /foo and that command does not exist, how do I send the message saying "This command does not exist"?
這可能很簡(jiǎn)單，但我有點(diǎn)困惑.
This is maybe pretty simple but I'm bit confused.
如果您需要更多信息，請(qǐng)發(fā)表評(píng)論.
If you need more info please comment.
謝謝！

你可以定義一個(gè) on_command_error 事件(請(qǐng)注意，與記錄的重寫分支相比，異步分支上的參數(shù)順序相反)如果出現(xiàn) CommandError ，將被調(diào)用.
You can define an on_command_error event (Note that the order of arguments is reversed on the async branch, compared to the documented rewrite branch) that will be called if there if a CommandError is raised.
然后您可以簽入 錯(cuò)誤處理程序 如果錯(cuò)誤是 CommandNotFound 錯(cuò)誤并相應(yīng)處理:
You can then check in that error handler if the error is a CommandNotFound error and handle it accordingly:
@bot.event
async def on_command_error(error, ctx):
if isinstance(error, commands.CommandNotFound):
await bot.send_message(ctx.message.channel, "No such command")
else:
raise error
這假設(shè)您正在使用 discord.ext.commands 擴(kuò)展來編寫命令(您應(yīng)該這樣做).
This assumes you are using the discord.ext.commands extension to write your commands (which you should).
這篇關(guān)于如何響應(yīng) discord.py 中的錯(cuò)誤用戶命令的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
