关于协程模块遇到的问题

在尝试爬取一本小说时报错，下面附完整代码和报错的问题

Task exception was never retrieved
future: <Task finished name='Task-2' coro=<download() done, defined at C:\Users\lenovo\Desktop\test\水浒传\水浒传模仿.py:7> exception=AttributeError('__aenter__')>
Traceback (most recent call last):
  File "C:\Users\lenovo\Desktop\test\水浒传\水浒传模仿.py", line 8, in download
    async with aiohttp.ClientSession as session:    #相当于request
AttributeError: __aenter__

import asyncio
import aiohttp

import requests

async def download(http,name):
    async with aiohttp.ClientSession as session:    #相当于request
            async with session.get(http) as resp2:  #相当于resp
                way2 = re.compile('r<div class="xstext">(?P<text>.*?)<div class="pagelist" id="pages">,re.S')
                href2 = way2.finditer(resp2.text)
                for it in href2:
                    async with aiofiles.open(name,mode = "wb") as f:
                        await f.write(it.group("text"))

async def web(url1):
    tasks = []
    url = "https://www.gdwxcn.com/gdxs/shz/"
    resp = requests.get(url)
    resp.encoding = "gbk"
    way = re.compile(r'<li><a href="/gdxs/shz/(?P<web>.*?)" target="_blank" >(?P<name>.*?)</a></li>', re.S)
    href = way.finditer(resp.text)
    for i in href:
        http = "https://www.gdwxcn.com/gdxs/shz/" + i.group("web")
        name = i.group("name")
        tasks.append(asyncio.create_task(download(http,name))) #将任务添加到下载函数download中

    await asyncio.wait(tasks)


if __name__ == '__main__':
    url ="https://www.gdwxcn.com/gdxs/shz/"
    asyncio.run(web(url))

我觉得你应该测试一下，正则匹配的字符串网址那，部分是否问题

as session 前面那个应该加括号，没记错的话

在write部分做了关于字节和文本的问题做修改了，但是仍然不能跑，

问题解决了吗？我也是这个问题
