I found answer to my own question:
class NoVerifyClientContextFactory:
"""A context factory for SSL clients."""
isClient = 1
method = SSL.SSLv3_METHOD
def getContext(self):
def x(*args):
return True
ctx=SSL.Context(self.method)
#print dir(ctx)
ctx.set_verify(SSL.VERIFY_NONE,x)
return ctx
def getPage(url, contextFactory=None, *args, **kwargs):
scheme, host, port, path = _parse(url)
factory = HTTPClientFactory(url, *args, **kwargs)
if 1: # use a proxy
host, port = 'localhost', 8080
factory.path = url
if scheme == 'https':
from twisted.internet import ssl
if contextFactory is None:
contextFactory = NoVerifyClientContextFactory()
reactor.connectSSL(host, port, factory, contextFactory)
else:
reactor.connectTCP(host, port, factory)
return factory.deferred
