Hi,
I use httpx AsyncClient to send a get request ,but always get the resonse content null, I change to use aiohttp ,it works ok ,get the right content.Here is my code:

async def httpxGetUrl(url):
    async with httpx.AsyncClient() as client:
        headers = {
            'Connection':'close'
        }
        resp = await client.get(url,headers=headers)
        client
        content = await resp.aread()
        print(content)
        
        # content = resp.text
        # print(content)
    
async def aiohttpGetUrl(url):
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as resp:
            token = await resp.text()
            print(token.encode('utf-8').decode('unicode_escape'))
            return token    
if __name__ == '__main__':
    import asyncio
    asyncio.run(httpxGetUrl('http://127.0.0.1:5000/Pay?Id=655cede5-5a3b-401d-00cf-9753508162e4'))
    
    # asyncio.run(aiohttpGetUrl('http://127.0.0.1:5000/Pay?Id=655cede5-5a3b-401d-00cf-9753508162e4'))

Start by reproducing the reported AsyncClient request in httpxGetUrl against the stated local URL, then compare its status, headers, and content with the aiohttpGetUrl version. Read the AsyncClient response-reading behavior around aread() and resp.text; done means identifying a reproducible cause for the empty content and documenting or testing the resulting behavior.
