#29 ZSI Digest Authentication implementaion for ProxyServices

[Jakob Simon-Gaarde]

Usage example (MapPoint SOAP Services):

from CommonService_services import *
loc = FindServiceLocator()
import sys
import ZSI
kw={'tracefile':sys.stdout, 'auth' : (
ZSI.AUTH.httpdigest, 'username', 'passwd') }
portType = loc.getFindServiceSoap(**kw)

AddressLine='Lergravsvej 28'
PostalCode='8660'
CountryRegion='DK'
InputAddress = ns1.Address_Def()
InputAddress._AddressLine = AddressLine
InputAddress._PostalCode = PostalCode
InputAddress._CountryRegion = CountryRegion

specification = ns1.FindAddressSpecification_Def()
specification._InputAddress = InputAddress
specification._DataSourceName = 'MapPoint.EU'
request = FindAddressSoapInWrapper()

request._specification = specification

res = portType.FindAddress(request)

This looks great, but you need to submit a real patch file if you want to see
your change make it into the project. We have too many things to do to
spend time dealing with non-standard patches. Please see; http://
unxutils.sourceforge.net/ for a diff command that will generate real patch
files on win32.

Hi Keith.

Right, here is the patch-file.
I don't know how to create a patch that adds new files so
the new digest_auth.py which is required you have to copy
from the previous attachment.

Note that have made a little change in wsdl2python.py too.
There is a problem when wsdl specifications include untyped
properties (wsdl2python, try for instance
http://staging.mappoint.net/standard-30/mappoint.wsdl\) w3c
specify untyped properties to be AnyType, so that's what I
have patched it to do.

Best Regards

Just to follow up on the wsdl2python problem I mentioned,
here is the thing: (from
http://staging.mappoint.net/standard-30/mappoint.wsdl\)

<s:complexType name="EntityPropertyValue">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Name"
type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Value"/>
</s:sequence>
</s:complexType>

The element name="Value" is untyped, that must result in an
AnyType type.

I have created a patch "digest_auth-20050918.patch" compared
with the cvs version og ZSI.
Please commit the changes soon, before client.py is changed
again.

Thanks.

When I try to download digest_auth.py I keep getting this error.

It's a python/txt file, how can you not download it!?

I have had three people download it with no problem, all
using Firefox.

Because the sourceforge site was having problems.

It just downloaded, sometimes this just happens and it's confusing.

Hi Joshua.

I forgot to mention that the changes I had made on
wsdl2python.py are no longer required (pulled out of the
patchfile), the problem seem to have been corrected in the
latest version on CVS.

I have tested it against mappoint, it seems to be working just
fine. Now the digest problem is solved. When you get your
account to MapPoint you might want to try to calculate a route. If
you do do you will experience the following error:

Traceback (most recent call last):
File "findservice.py", line 67, in ?
calculateRoute([loc1,loc2],sys.stdout)
File "findservice.py", line 58, in calculateRoute

This is beyond the digest problem, and the next problem to
address in order to get MapPoint working. All other MapPoint
functions I have tried works find (like address matching, version
info etc.).

Would you like to help out so ZSI can be promoted as MapPoint
compliant?

BTW: I have attached a script that calculates the route
(findservice.py - just add your digest credentiels) thereby
provoking the error mentioned before.

I will submit this to the bugtracker. But as I said, it
would be nice
with another pair of eyes on this subject. Being MapPoint
compliant is great advertisement for ZSI.
