HTTPS requests over HTTP proxy problem

[zzl221000]

Describe the bug
Unable to use proxy to access many https sites.

To Reproduce
Steps to reproduce the behavior:

async with aiosonic.HTTPClient(proxy=Proxy(proxy)) as client:
    resp = await client.get('https://github.com')
    print(resp.status) # 301
    print(resp.headers) # HttpHeaders({'Content-Length': '0', 'Location': 'https://github.com/'})
    resp2 = await client.get('https://github.com/')
    print(resp2.status) # 301
    print(resp2.headers) # HttpHeaders({'Content-Length': '0', 'Location': 'https://github.com/'})

Expected behavior
Response 200

Additional context
After debugging, I found that aiosonic uses the proxy without the CONNECT method to create the tunnel.

Oh thanks!

I have missed that feature as you say, I don't know when I'll find a room for solving it, I hope in a week or two
