如何将base64解码为图像discord.py并发送

import discord
import base64
from io import BytesIO

client = discord.Client()

@client.event
async def on_message(message):
    if message.content.startswith('!send_image'):
        # 获取base64编码的图像数据
        encoded_image = message.content.split(' ')[1]
        
        # 解码base64数据为二进制
        decoded_image = base64.b64decode(encoded_image)
        
        # 创建一个BytesIO对象来读取二进制数据
        image_data = BytesIO(decoded_image)
        
        # 发送图像到Discord
        await message.channel.send(file=discord.File(image_data, 'image.png'))

client.run('YOUR_DISCORD_TOKEN')
