discord.py - DM 成员的错误命令

discord.py - Error command with DM member

我想为我的代码创建一个错误命令,它会在 dms 关闭或找不到用户时显示,这是我的代码:

@client.command()
async def DM(ctx, user: discord.User, *, message=None):
        message = message or "DM message to be sent"
        await user.send(message)

就这么简单:

您可以阅读文档 here。如果您无法发送消息,它将引发禁止错误。

@client.command()
async def DM(ctx, user: discord.User, *, message=None):
        message = message or "DM message to be sent"
        try:
            await user.send(message)
        except: 
            await ctx.send("Failed to send Dm")
