How to use the aiocqhttp.CQHttp function in aiocqhttp

from aiocqhttp import CQHttp, ApiError

bot = CQHttp(api_root='http://127.0.0.1:5700/',
             access_token='123',
             secret='abc')


@bot.on_message
# 上面这句等价于 @bot.on('message')
async def handle_msg(context):
    # 下面这句等价于 bot.send_private_msg(user_id=context['user_id'], message='你好呀，下面一条是你刚刚发的：')
    try:
        await bot.send(context, '你好呀，下面一条是你刚刚发的：')
    except ApiError:
        pass
    return {'reply': context['message'],
            'at_sender': False}  # 返回给 HTTP API 插件，走快速回复途径
