Discord机器人报错：'Member'对象无'avatar_url_as'属性求助

开发Discord机器人的wanted命令时，代码运行报错，错误提示AttributeError: 'Member' object has no attribute 'avatar_url_as'。

原代码 #

import discord
from discord.ext import commands
import datetime
import asyncio
import random
from config import settings

from PIL import Image
from io import BytesIO


client = commands.Bot(command_prefix = settings['PREFIX'], intents=discord.Intents.all())
client.remove_command('help')

@client.event
async def on_ready():
    # status_task.start()
    print('Ready')

@client.command()
async def wanted(ctx, user: discord.Member = None):
    if user == None:
        user = ctx.author
        
    wanted = Image.open('tester.jpg')

    asset = ctx.author.avatar_url_as(size = 128)
    data = BytesIO(await asset.read())
    pfp = Image.opem(data)

    pfp = pfp.resize((177,177))

    wanted.paste(pfp, (120,212))

    wanted.save("profile.jpg")

    await ctx.send(file = discord.File("profile.jpg"))

报错信息 #

Traceback (most recent call last):
  File "C:\Users\Астик\AppData\Local\Programs\Python\Python310\lib\site-packages\discord\ext\commands\bot.py", line 360, in invoke

你的代码存在两个关键问题：

• avatar_url_as方法已被移除
  discord.py v2.x版本中，Member对象的avatar_url_as方法被移除。现在需要通过以下方式获取用户头像：

  • 用户有自定义头像时，使用user.avatar获取Avatar对象，再调用with_size(尺寸)指定大小
  • 用户没有自定义头像时，回退到默认头像user.default_avatar

• 拼写错误
  代码中Image.opem(data)是笔误，正确写法为Image.open(data)

修复后的完整代码：

import discord
from discord.ext import commands
import datetime
import asyncio
import random
from config import settings

from PIL import Image
from io import BytesIO


client = commands.Bot(command_prefix = settings['PREFIX'], intents=discord.Intents.all())
client.remove_command('help')

@client.event
async def on_ready():
    # status_task.start()
    print('Ready')

@client.command()
async def wanted(ctx, user: discord.Member = None):
    if user is None:
        user = ctx.author
        
    wanted = Image.open('tester.jpg')

    # 优先获取自定义头像，无自定义头像则用默认头像
    avatar = user.avatar or user.default_avatar
    # 读取指定尺寸的头像数据
    data = BytesIO(await avatar.with_size(128).read())
    pfp = Image.open(data)

    pfp = pfp.resize((177,177))

    wanted.paste(pfp, (120,212))

    wanted.save("profile.jpg")

    await ctx.send(file=discord.File("profile.jpg"))

额外提示：

• 建议使用user is None代替user == None，这是Python的规范写法
• 确保tester.jpg文件位于脚本的同目录下，否则需要填写完整文件路径
