我如何做到这一点，以使每个人都无法使用echo命令 [英] How do I make it so that you can't @everyone with an echo command

问题描述

我想添加一种方法，以使您无法使用echo命令对角色执行ping操作.我能想到的唯一方法是检查内容"是否以@开头，然后它仅显示一条消息，回答不，我该怎么办?".

I want to add a way so that you cannot ping roles with the echo command. The only way I can think of is to check if 'content' starts with @ then it just responds with a message saying no, how can I do that?

@client.command()
async def echo(ctx, *, content:str):
    await ctx.send(content)
    print("Echo command works")

推荐答案

我们可以控制在以allowed_mentions发送的邮件中执行ping操作

We can control pings in a message we send with allowed_mentions,

allowed_mentions = discord.AllowedMentions(everyone=False) 
await ctx.send(content, allowed_mentions=allowed_mentions)

这将成功发送回声，即使每个人都执行ping操作，但不会ping所有人.如果您想回覆使用者说 No ，我们必须检查提及内容并回覆.

This will successfully send the echo, even if there is an everyone ping, but will not ping everyone. If you want to reply to the user saying No, we have to check for mentions and reply.

mentions = ctx.message.role_mentions
if any([mention.is_default() for mention in mentions]): # there is an everyone mention
    return await ctx.send('No')
else:
    # do stuff
