how can I connect nginx-1.11.5 by http2.0

well I start a nginx-1.11.5
when I connect the server by chrome and FireFox
I can see the access.log as follows
"GET / HTTP/2.0" 200 728 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36"

but when I use these code:

context = ssl._create_unverified_context()
conn = HTTPConnection('xxx.com', 8443, True, None, False, context)
conn.request('GET', '/index.html')
resp = conn.get_response()

I see the log
"GET /index.html HTTP/1.1" 200 612 "-" "-"

what is the deference between these too ways

thank you

Can you please provide me with the following information?

  • the output from python --version
  • the output from python -c "import ssl; print(ssl.OPENSSL_VERSION)"
  • the output from python -c "import platform; print(platform.platform())"
  • the output from pip freeze
  • the output from python -c "from cryptography.hazmat.backends.openssl import backend; print(backend.openssl_version_text())"

Ah, sorry, I see the problem.

You're using a context you created yourself, rather than ours. That means it doesn't do the protocol negotiation. Try changing your code to this:

context = hyper.tls.init_context()
context.check_hostname = False
context.verify_mode = ssl.CERT_NONE

conn = HTTPConnection('xxx.com', 8443, True, None, False, context)
conn.request('GET', '/index.html')
resp = conn.get_response()

That should resolve your issue.
