python-3.x - Discord.py Cogs 中的 client.(variable) 变量

问题描述

将我的 python 代码迁移到 discord.py 时遇到问题。问题是，我不知道如何使用客户端。discord.py cogs 中的变量如client.sniped_messages = {}... 它显示错误 -

Traceback (most recent call last):
  File "C:\Users\arjun\Documents\Arjun\Python\discord.py\swayde\main.py", line 55, in <module>
    client.load_extension(f"cogs.{filename[:-3]}")
  File "C:\Users\arjun\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\ext\commands\bot.py", line 678, in load_extension
    self._load_from_module_spec(spec, name)
  File "C:\Users\arjun\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\ext\commands\bot.py", line 609, in _load_from_module_spec
    raise errors.ExtensionFailed(key, e) from e
discord.ext.commands.errors.ExtensionFailed: Extension 'cogs.Utility' raised an error: NameError: name 'self' is not defined

这是代码 -

import discord
from discord.ext import commands
import random
import datetime

class Utility(commands.Cog):

    def __init__(self, client):
        self.client = client

    self.client.sniped_messages = {}
    @commands.Cog.listener()
    async def on_message_delete(self,message):
        self.client.sniped_messages[message.guild.id] = (message.content, message.author, message.channel.name, message.created_at)

    @commands.command()
    async def snipe(self, ctx):
        try:
            contents, author, channel_name, time = self.client.sniped_messages[ctx.guild.id]
        except:
            await ctx.channel.send("Couldn't find a message to snipe!")
            return

        embed = discord.Embed(description=contents, color=discord.Color.purple(), timestamp=time)
        embed.set_author(name=f"{author.name}#{author.discriminator}", icon_url=author.avatar_url)
        embed.set_footer(text=f"Deleted in : #{channel_name}")

        await ctx.channel.send(embed=embed)

def setup(client):
    client.add_cog(Utility(client))

现在，当我删除变量client.sniped_messages = {}时，代码运行完美。

请告诉我如何解决这个问题以及如何.client在 cogs 中使用变量。

提前致谢！

解决方案

你必须缩进self.client.sniped_messages = {}，所以它在__init__方法里面

def __init__(self, client):
    self.client = client
    self.client.sniped_messages = {}
