有没有办法获取命令的参数？

Question

我想知道是否有办法获取命令的参数以显示如何使用它。我有一个自定义帮助命令，但我尝试做一些使用与装饰器中相同的描述的事情。它不起作用（没有给我任何错误或任何东西）但我不知道为什么。

@commands.command()
    async def format(self, ctx, command):
        formatting = discord.Embed(title=f"Formatting for .{command}", description=command.description)
        formatting.set_thumbnail(url=self.bot.avatar_url)
        formatting.set_footer(text=f"Requested by {ctx.author.mention}", icon_url=ctx.author.avatar_url)

        ctx.send(embed=formatting)

这是我的一个有描述的命令：

"""Change Nickname command"""
    @commands.command(aliases=['chnick'], description="Usage: .nick [member mention] [nickname to change to]")
    @commands.has_permissions(manage_channels=True)
    async def change_nick(self, ctx, member: discord.Member, nick):
        """Changes a user's nickname\nAliases: chnick"""

        await member.edit(nick=nick)
        await ctx.send(f"Nickname was changed for {member.mention}")

您需要使用get_command()获取命令

@commands.command()
async def format(self, ctx, command):
    command = self.bot.get_command(command)
    formatting = discord.Embed(title=f"Formatting for .{command.name}", description=command.description)
    formatting.set_thumbnail(url=self.bot.avatar_url)
    formatting.set_footer(text=f"Requested by {ctx.author.mention}", icon_url=ctx.author.avatar_url)
    await ctx.send(embed=formatting)
