Problems when using proxy under Windows #4536
Description
Long story short
I get an error when running the following code under Python 3.8.1 and aiohttp3.6.2 under Windows
import aiohttp
import asyncio
async def main():
async with aiohttp.ClientSession() as session:
async with session.get('https://python.org', proxy='http://127.0.0.1:8888') as response:
print("Status:", response.status)
print("Content-type:", response.headers['content-type'])
html = await response.text()
print("Body:", html[:15], "...")
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
Expected behaviour
Status: 200
Content-type: text/html; charset=utf-8
Body: <!doctype html> ...
Actual behaviour

Steps to reproduce
Run the above code
Your environment
OS: windows7
proxy: v2ray
aiohttp: 3.6.2(client)
python: 3.8.1
When I remove the proxy parameter, it works fine
