Cog 中的装饰器@bot.tree.command

Question

我应该如何在课堂上使用装饰器@bot.tree.command？

我的主要文件：

import os
import discord
from dotenv import load_dotenv
from discord.ext import commands, tasks

extens = ["cogs.slash_commands"]


class MyBot(commands.Bot):

    def __init__(self):
        super().__init__(command_prefix='/', intents=discord.Intents.all())

    async def on_ready(self):
        print(f'{self.user} is now running!')
        for cog in extens:
            try:
                await bot.load_extension(cog)
                print(f"{cog} was loaded.")
            except Exception as e:
                print(e)
bot = MyBot()
load_dotenv()
bot.run(os.getenv('TOKEN'))

我的齿轮看起来像这样

import discord
from discord import app_commands
from discord.ext import commands


class SlashCommands(commands.Cog):
    
    def __init__(self, bot):
        self.bot = bot

    @commands.tree.command
    async def hello(self, interaction: discord.Interaction, thing_to_say: str):
        await interaction.response.send_message(f"{thing_to_say}")


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

当我编译时它说：

扩展“cogs.slash_commands”引发错误：AttributeError：模块“discord.ext.commands”没有属性“tree”

我该怎么办？我应该在主文件中添加什么并在 cog 文件中编辑什么？

discord.ext.commands

没有树属性，你的

bot

有。

在我的代码中，没有类，我使用

bot = commands.Bot(command_prefix="!", intents=discord.Intents.all()) 
#make sure your bot variable is correctly being assigned to the intents 

@bot.event #dont forget this in your code
async def on_ready():
    print('Bot is now running!')
    try:
        synced = await bot.tree.sync() #should be the same as your cog system
    except Exception as e:
        print(e)

#accessing the tree within the bot, not the tree within the commands
@bot.tree.command(name="website", description="Get the link to our website")
async def website(interaction: discord.Interaction):
    await interaction.response.send_message("https://www.stackoverflow.com")
