I am able to modify the code in transport.py and enable NTLM authentication using PycURL. But the pycurl library or the inside libcurl is not friendly with SOAP request using NTLM authentication, it always send request with invalid "content-length", although it is already correctly specified in header of the client. I always get http error 411 when trying to call SOAP web service function with NTLM authentication through PycURL.
Here is the error information: <?xml version="1.0" ?><soap:Envelope xmlns:soap= "http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd= "http://www.w3.org/2001/XMLSchema"; xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance";> <soap:Header/> <soap:Body> <GetSampleInfoById xmlns="http://tempuri.org/";> <sampleId>de63c455-0849-4716-abb0-43d0a52073cf </sampleId></GetSampleInfoById> </soap:Body> </soap:Envelope> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd";> <HTML><HEAD><TITLE>Length Required</TITLE> <META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii" ></HEAD> <BODY><h2>Length Required</h2> <hr><p>HTTP Error 411. The request must be chunked or have a content length. </p> </BODY></HTML> Since in SUDS, they use python-ntlm to allow NTLM authentication utilizing "urllib2", then I tried to modify the code in "urllib2Transport" class of pysimplesoap's transport.py, and enable NTLM authentication using urllib2 transport. It works finally. Here is the modifications: Original code: class urllib2Transport(TransportBase): _wrapper_version = "urllib2 %s" % urllib2.__version__ _wrapper_name = 'urllib2' def __init__(self, timeout=None, proxy=None, cacert=None, sessions=False): if (timeout is not None) and not self.supports_feature('timeout'): raise RuntimeError('timeout is not supported with urllib2 transport') if proxy: raise RuntimeError('proxy is not supported with urllib2 transport') if cacert: raise RuntimeError('cacert is not support with urllib2 transport') self.request_opener = urllib2.urlopen if sessions: opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(CookieJar())) self.request_opener = opener.open self._timeout = timeout def request(self, url, method="GET", body=None, headers={}): req = urllib2.Request(url, body, headers) try: f = self.request_opener(req, timeout=self._timeout) return f.info(), f.read() except urllib2.HTTPError as f: if f.code != 500: raise return f.info(), f.read() Modified code: class urllib2Transport(TransportBase): _wrapper_version = "urllib2 %s" % urllib2.__version__ _wrapper_name = 'urllib2' def __init__(self, timeout=None, proxy=None, cacert=None, sessions=False ): if (timeout is not None) and not self.supports_feature('timeout'): raise RuntimeError('timeout is not supported with urllib2 transport') #if proxy: # raise RuntimeError('proxy is not supported with urllib2 transport') self.proxy = proxy or {} if cacert: raise RuntimeError('cacert is not support with urllib2 transport') self.request_opener = urllib2.urlopen if sessions: opener = urllib2.build_opener(urllib2.HTTPCookieProcessor( CookieJar())) self.request_opener = opener.open self._timeout = timeout def request(self, url, method="GET", body=None, headers={}): req = urllib2.Request(url, body, headers) if 'proxy_user' in self.proxy: from ntlm import HTTPNtlmAuthHandler passman = urllib2.HTTPPasswordMgrWithDefaultRealm() passman.add_password(None, url, self.proxy['proxy_user'], self. proxy['proxy_pass']) # create the NTLM authentication handler auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman) # create and install the opener opener = urllib2.build_opener(auth_NTLM) self.request_opener = opener.open try: f = self.request_opener(req, timeout=self._timeout) return f.info(), f.read() except urllib2.HTTPError as f: if f.code != 500: raise return f.info(), f.read() Now, we can create the client object for SOAP service with NTLM authentication by: import sys sys.path.append("/home/www-data/web2py") import gluon.contrib.pysimplesoap.client as SSclient user = 'XXXXXXX' password = "***********" URL = "https://XXX.XXX.XXX.XXX/YYYY?wsdl <https://54.153.5.133:53441/ForAGISService?wsdl>" proxy={'proxy_user':user,'proxy_pass':password} SSclient.Http = set_http_wrapper(library='urllib2') client=SSclient.SoapClient(wsdl=URL,proxy=proxy) On Tuesday, June 9, 2015 at 3:32:03 PM UTC-4, Derek wrote: > > alright, well you are going to have to modify the client.py for > pysimplesoap then in order to achieve this. > I'd suggest you add a variable to the class like 'USERPWD' and populate > it.
