使用python肥皂水使用用php编写的soap webservice，发生SAXParseException错误

Question

I Use the following code to use a soap webservice written in PHP

#!/usr/local/bin/python

import logging
logging.basicConfig(levee = logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.wsdl').setLevel(logging.DEBUG)
import urllib2
from suds.client import Client
from suds.sax.element import Element


url = 'a sopa webservice url'
client = Client(url)

It comes out the following error:

Traceback (most recent call last):
File "./auth.py", line 13, in <module>
   client = Client(url)
File "build/bdist.linux-x86_64/egg/suds/client.py", line 112, in __init__

self.close()

self.feed("", isFinal = 1)

File "/usr/local/lib/python2.7/xml/sax/handler.py", line 38, in fatalError
raise exception

I'm new to suds and sopa webservice,I don't know what the error means, can someone can give me some advices

You'll need this line to debug that:

logging.getLogger('suds.transport').setLevel(logging.DEBUG)

Sample output:

DEBUG:suds.transport.http:received:

Apparently even the maintained suds-jurko fork doesn't throw an error when using a login with insufficient rights.

Typically, this means the server is returning data, but it is not valid XML. It's likely a server problem.
