[Fedora-suds-list] call an HTTPS service via a proxy ...
Hi,
I'm porting a small web service app from ZSI to suds.
I'm having trouble connecting to an https:// service URL
via a proxy.
If I use no proxy things seem ok; if I set up a proxy the connection
appears to hang; an strace of the process suggests that the process
connects to the proxy server and speaks raw SSL without the necessary:
CONNECT real-host:443 HTTP/1.0
that is needed as a preamble to hop through the proxy.
I'm using suds-0.3.8 and python-2.6.4; the former because it is current
and the latter because it contains https-via-proxy support in urllib2.
The setup code looks like this:
client = Client(wsdlURL)
if os.environ.get('WEBPROXY'):
proxy = { 'http': os.environ['WEBPROXY'],
'https': os.environ['WEBPROXY'],
}
print "proxy =", `proxy`
sys.stdout.flush()
client.set_options(proxy = proxy)
client.set_options(location = 'https://localhost/foo-service')
where $WEBPROXY contains "localhost:3128", wsdlURL is a file:// URL to
my test WSDL and https://localhost/foo-service is a dummy URL to
test the service before harassing a real instance.
I believe suds is not speaking to urllib2 correctly to activate the
proxy tunnel.
The pre-suds app was making direct urllib2 calls and set things up like
this (yes, a different environment variable):
proxy_support = urllib2.ProxyHandler({"http" :
os.environ['http_proxy'],
"https" :
os.environ['http_proxy']})
opener = urllib2.build_opener(proxy_support)
urllib2.install_opener(opener)
and things quietly worked. That doesn't seem to have any effect if I get
suds to make the calls.
Can anyone suggest how I _should_ be setting this up for suds?
Cheers,
