Description: ONVIF defines the Uplink service based on HTTP/2 and connection
reversal, in order to have cameras connect to cloud services while
having NAT between themselves and the remote service (For details,
https://www.onvif.org/specs/srv/uplink/ONVIF-Uplink-Spec.pdf)
With this patch, it is possible on the cloud side to accept an incoming
connection from a listining socket and to pass the new socket to
HTTP20Connection, so that the cloud software can use the reverted
connection and turn itself into a client.
Example code for implementing it:
import socket, ssl, time
from hyper import HTTP20Connection
from hyper.common.bufsocket import BufferedSocket
context = ssl.SSLContext (ssl.PROTOCOL_TLSv1_2)
context.load_cert_chain ("server.cert", "server.key")
bindsocket = socket.socket ()
bindsocket.bind(('', 8081))
bindsocket.listen(5)
with context.wrap_socket (bindsocket, server_side=True) as ssock:
while True:
newsocket, fromaddr = ssock.accept()
req = newsocket.read ()
if b'Connection: Upgrade' in req and b'Upgrade: h2c-reverse':
newsocket.write (b'HTTP/1.1 101 Switching Protocols\r\nConnection: Upgrade\r\nUpgrade: h2c-reverse\r\n\r\n')
newsocket.write (b'PRI * HTTP/2.0\r\n\r\nSM\r\n\r\n')
c = HTTP20Connection ('unused.org', external_socket = BufferedSocket (newsocket))
c.request('POST', '/onvif/device_service', headers = { 'Content-Type': 'application/soap+xml; charset=utf-8'}, body=b'
