检查用户是否对某个带有齿轮的表情符号做出反应

Question

我有一个问题。我如何检查用户使用了哪个表情符号?如何检查特定用户是否对特定消息有反应[discord.py]

我想检查反应是✅还是❌

文件夹结构

├── main.py
├── cogs
│   ├── member.py

问题是我没有得到错误消息。什么也不会发生。当我用表情符号回应时，什么也没发生。

member.py

import discord
from discord.ext import commands
from datetime import datetime
class command(commands.Cog):
def __init__(self, bot):
self.bot = bot

@commands.Cog.listener()
async def on_message(self, message):
...
...
for emoji in emojis:
await msg.add_reaction(emoji)

await message.author.send('Send me that ✅ reaction, mate')
def check(reaction, user):
return user == message.author and str(reaction.emoji) == '✅'
res = await self.bot.wait_for(
"reaction_add",
check=check, timeout=None
)
print(res.emoji)
if res.content.lower() == "✅":
await message.author.send("Got it")
else:
await message.author.send("Thanks")

confirmation = await self.bot.wait_for("reaction_add", check=check)
await message.author.send("You responded with {}".format(reaction.emoji))

async def setup(bot):
await bot.add_cog(command(bot))

Answer 1

您正在使用一个名为check的函数，它不存在-就像您的错误告诉您一样。在你的类中有一个，但它不在同一个作用域中，所以你不能用它的名字来调用它。

访问类中的方法，使用self.<name>。

同样，您应该只传递检查函数，而不是调用。

(..., check=self.check

编辑原问题中的代码经过编辑。您没有异步加载齿轮。扩展,在2.0中，齿轮是异步的。文档:https://discordpy.readthedocs.io/en/stable/migrating.html extension-and-cog-loading-unloading-is-now-asynchronous

将此代码放入@commands.Cog.listener()装饰器中，如果cogs加载器正常工作，该代码将正常工作。如果你想让我给你看看我的装载机，我可以。

accept = '✅'
decline = '🚫'
def check(reaction, user):
return user == author
messsage = await ctx.send("test")
await message.add_reaction(accept)
await message.add_reaction(decline)
reaction = await self.bot.wait_for("reaction_add", check=check)
if str(reaction[0]) == accept:
await ctx.send("Accepted")
elif str(reaction[0]) == decline:
await ctx.send("Denied")
