with curl and https - Githubissues

I try to combine pycurl and httptools, but I found it can't deal with https, here is my code:

success with http:

import pycurl
import httptools

class HttpResponse:
    def on_message_begin(self):
        print('on_message_begin')
    def on_url(self, url: bytes):
        print(f'on_url: url={url}')
    def on_header(self, name: bytes, value: bytes):
        print(f'on_header: name={name}, value={value.decode("ISO-8859-1")}')
    def on_headers_complete(self):
        print(f'on_header_complete')
    def on_body(self, body: bytes):
        print(f'on_body: {len(body)}')
    def on_message_complete(self):
        print(f'on_message_complete')
    def on_chunk_header(self):
        print(f'on_chunk_header')
    def on_chunk_complete(self):
        print(f'on_chunk_complete')
    def on_status(self, status: bytes):
        print(f'on_status: status={status}')

print(pycurl.version)
print(httptools.__version__)
m = HttpResponse()
p = httptools.HttpResponseParser(m)

c = pycurl.Curl()
c.setopt(pycurl.URL, "http://uvloop.readthedocs.io/")
c.setopt(pycurl.HTTP_TRANSFER_DECODING, 0)
c.setopt(pycurl.WRITEFUNCTION, p.feed_data)
c.setopt(pycurl.HEADERFUNCTION, p.feed_data)
c.perform()

and output:

by the way, how can i let httptools auto decode with Accept-Encoding: gzip,deflate

MagicStack / httptools
