如何防止用户在频道中发送多条消息? [英] How do I prevent a user from sending more than one message in a channel?
问题描述
User 1: Hello!
User 1: How are you?
User 2: I'm good.
User 2: hbu
User 3: hey guys!
User 1: i'm doing fine
我正在尝试从用户 1 和用户 2 中删除第二条消息，这样任何用户都只能发送一条消息.我被告知要使用 channel.history，但我想不出一种方法来比较消息的作者以确保它们不是同一个人.
I'm trying to delete the second message from User 1 and User 2, so that any user can only send a single message. I was told to use channel.history, but I can't think of a way to compare the author's of the messages to make sure they aren't the same person.
这就是我想要的:我想防止重复发布:
This is what I want: I want to prevent double posting:
User 1: Hello! How are you?
User 2: I'm good, hbu.
User 3: hey guys!
User 1: i'm doing fine
我只是不知道如何使用 channel.history 来做到这一点.
I just don't know how to use channel.history to do this.
推荐答案
您可以使用 on_message() 事件并将频道历史记录的限制设置为 2:
You can use the on_message() event and set the channel history's limit to 2 for this:
@bot.event
async def on_message(message):
recent_author = (await message.channel.history(limit=2).flatten())[1].author
if message.author == recent_author:
await message.delete()
history() 协程首先获取最新消息，除非另有说明，因此您可以将限制设置为 2 以获取用户刚刚发送的消息之前的最新消息.
The history() coroutine gets the newest messages first, unless specified otherwise, so you can set the limit to 2 to get the most recent message before the one the user just sent.
