(Discord.py) 斜线命令问题 (app_commands)

Question

I'm having trouble with making slash commands. So, I'm learning how to create app commands in discord.py, but my bot doesn't respond to the commands. By the way, i didn't get any error messages.

Cog

import time
import discord
from discord.ext import commands
from discord import app_commands
from discord.ext.commands import Context
from discord.ext.commands import Bot

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

    @commands.Cog.listener()
    async def on_ready(self):
        print("Ping.py is ready!")


    @commands.command()
    async def ping(self, ctx):
        yo = round(self.bot.latency * 1000)
        embed = discord.Embed(title="Pong! :ping_pong:", color=discord.Color.random())
        embed.add_field(name="Latency:", value=f"{yo}ms")
        await ctx.send(embed=embed)


    @app_commands.command(name="hi", description="Say hi!")
    async def hi(self, interaction: discord.Interaction, word:str):
        await interaction.response.send_message(f"Hi {word}!")

    @app_commands.command(name="num", description="Random numbers")
    async def num(self, interaction: discord.Interaction, *, first: int, second: int) -> None:
        szam = random.randint(first, second)
        embed = discord.Embed(title="Random number", color=discord.Color.random())
        embed.add_field(name=f"{context.author}'s number is:{szam}", value=f"Lowest:{first} | Highest:{second}",
                        inline=False)
        embed.timestamp = datetime.datetime.utcnow()
        await interaction.response.send_message(embed=embed)

    @app_commands.command(name="test", description="test")
    async def test(self, interaction: discord.Interaction, szam:str):
        await interaction.response.send_message(f"Szám:{szam}")

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

Main.py

import os
import discord
from discord.ext import commands
import asyncio
import requests
import json
from discord.utils import get
from discord.utils import find
import datetime
import random
from discord import app_commands

bot = commands.Bot(command_prefix="!", intents=discord.Intents.all(), help_command=None)

@bot.event
async def on_ready():
    print("Successfully connected to the server!")
    await bot.change_presence(activity=discord.Activity(type=discord.ActivityType.watching, name=f"{len(bot.guilds)} server | !help"))


async def load():
    for filename in os.listdir('./cogs'):
        if filename.endswith('.py'):
            await bot.load_extension(f'cogs.{filename[:-3]}')

async def main():
    async with bot:
        await load()
        await bot.start("")


asyncio.run(main())

PS: The "hi" command works fine, but there others are not working.

I checked the bot's intents, and the bot's permissions, but everything is fine and the commands still not working.

In discord.py 2, you have to sync the commands (in order for them to show up) yourself using app_commands.CommandTree.sync . Modified example from discord.py GitHub.

MY_GUILD = discord.Object(id=0)  # replace with your guild id

# In this basic example, we just synchronize the app commands to one guild.
# Instead of specifying a guild to every command, we copy over our global commands instead.
# By doing so, we don't have to wait up to an hour until they are shown to the end-user.
async def setup_hook():
    # This copies the global commands over to your guild.
    bot.tree.copy_global_to(guild=MY_GUILD)
    await bot.tree.sync(guild=MY_GUILD)

bot.setup_hook = setup_hook
