python-3.x - 不和谐的欢迎机器人

Question

因此，我尝试制作一个机器人，每次用户加入我的服务器时都会将其嵌入到特定 channel 。
代码看起来像这样

import discord
import asyncio
import datetime
from discord.ext import commands

intents = discord.Intents()
intents.members = True
intents.messages = True
intents.presences = True

bot = commands.Bot(command_prefix="a!", intents=intents)

@bot.event
async def on_ready():
    print('Bot is ready.')

@bot.event
async def on_member_join(ctx, member):
    embed = discord.Embed(colour=0x1abc9c, description=f"Welcome {member.name} to {member.guild.name}!")
    embed.set_thumbnail(url=f"{member.avatar_url}")
    embed.set_author(name=member.name, icon_url=member.avatar_url)
    embed.timestamp = datetime.datetime.utcnow()

    channel = guild.get_channel(816353040482566164)

    await channel.send(embed=embed)

我有一个错误

Ignoring exception in on_member_join
Traceback (most recent call last):
  File "C:\Users\Piero\AppData\Roaming\Python\Python39\site-packages\discord\client.py", line 343, in _run_event
    await coro(*args, **kwargs)
  File "C:\Users\Piero\Documents\Discord\a-chan\achan_bot\main.py", line 24, in on_member_join
    channel = guild.get_channel(816353040482566164)
NameError: name 'guild' is not defined

有人知道我的代码有什么问题吗？

首先来看 discord.py documention , ctx没有传递给 on_member_join事件引用。但是，您可以使用 attributes of member 这是为了获得您需要的值而传递的。

@bot.event
async def on_member_join(member):
    embed = discord.Embed(
        colour=0x1abc9c, 
        description=f"Welcome {member.name} to {member.guild.name}!"
    )
    embed.set_thumbnail(url=f"{member.avatar_url}")
    embed.set_author(name=member.name, icon_url=member.avatar_url)
    embed.timestamp = datetime.datetime.utcnow()

    channel = member.guild.get_channel(816353040482566164)
    await channel.send(embed=embed)

有趣的是，你这样做是为了获得公会名称，但似乎你在检索 channel 时忘记这样做了。 .
