Research direction

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.

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'))
