Subject: [Soap-Python] 'pysimplesoap' - Server - Handling 'mustUnderstand'
Message-ID: <E05D31B9-9399-482A-9C5E-E82F588E3365@icloud.com>

Mariano, ?pysimplesoap? community support -

I am evaluating use of ?pysimplesoap? framework. In particular, I have following POC (?proof of concept?) request:

?develop a SOAP Server that talks to both MySQL and Oracle databases and uses the standard AT&T CommonHeader. Must understand the mustunderstand attribute. Object oriented and must not just use strings of XML ?

Common header referenced is just a standard ?wise:Security? header:

<soapenv:Header>
<wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<wsse:UsernameToken wsu:Id="UsernameToken-29" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsse:Username>Username</wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">Password</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>


I am trying to use ?pysimplesoap? to implement this POC? 

Since there is no good documentation (other than very simple and limited online wiki samples), I need help understanding how to implement the ?mustUnderstand? requirement. From what I was told, adding ?mustUnderstand? attribute to a header - *must* result in that header being processed by the server, and if error occurs (or if there is no corresponding actor to process given header at all), exception must be raised.

I encountered two separate problems with ?mustUnderstand? header attribute:

wsse.UserameToken generates header without ?mustUnderstand? attribute (when used from test client). I did not find an obvious way of adding this attribute - without overriding UsernameToken.preprocess() method
Even after I did manage to add ?mustUnderstand? attribute to wsse:Security header - I am not sure how to define a handler (within server implementation) to handle (process) this header. But what?s even more worrisome - is that without corresponding handler, I *do not* get exception raised! I even tested with some arbitrary (custom) header that I added within client module (which includes ?mustUnderstand=1? attribute), and still did not get exception...


So questions are:

How is it possible to add arbitrary attribute to a header (that?s already defined)? Specifically - how ?mustUnderstand? can be added to wsse.UsernameToken without overriding that class?
Why server implementation does not raise exception when ?mustUnderstand? attribute is set to true in the header, and there is no appropriate handler to process that header?
How exactly custom handler (for a header) can be defined within server implementation?


Please help!

Slight correction to question #3 below:

Subject: [Soap-Python] Setting attributes in SOAP responses through
 pysimplesoap SoapDispatcher
Message-ID: <55DCE1E4.6070609@hypgnosys.org>

Hello pysimplesoap-ers,

I'm trying to use pysimplesoap to serve replies with XML attributes.

A snippet of the kind of message I'd like to be able to generate with 
SoapDispatcher, coming from docs for ONVIF (IP video interoperability 
standards):

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://www.w3.org/2003/05/soap-envelope"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tt="http://www.onvif.org/ver10/schema"
xmlns:trt="http://www.onvif.org/ver10/media/wsdl">
<SOAP-ENV:Body>
<<trt:GetProfilesResponse>
<trt:Profiles fixed="true" token="Profile1">
<tt:Name>Profile1</tt:Name>
<tt:VideoSourceConfiguration xsi:type="tt:VideoSourceConfiguration"
token="video_source_config">
...

How might I set the "fixed" and "token" attributes of the "trt:Profiles" 
element in my dispatcher fn "get_profiles()", below?

Code snippet thus far:

def get_profiles():
     ret = {
         'trt:Profiles' : { # how can I set attributes here?
             'tt:Name' : 'blahblahblah'
         }
     }

...

     dispatcher = SoapDispatcher(
         'my_dispatcher',
         location='http://localhost:8080/',
         action='http://localhost:8080',
         namespace='http://www.onvif.org/ver10/media/wsdl',
         prefix='trt',
         namespaces={
             'trt' : 'http://www.onvif.org/ver10/media/wsdl',
             'tt' : 'http://www.onvif.org/ver10/schema'
         },
         trace=True,
         ns=True
     )

     dispatcher.register_function(
         'GetProfiles',
         get_profiles,
         args={},
         returns={
             'trt:Profiles' : {
                 'tt:Name' : str
                 # ... and lots of other stuff, TBI
             }
         }

     )

Cheers,

Mark.

Subject: [Soap-Python] Library for bi-directional SOAP over HTTP
Message-ID: <20150830170450.GA18188@hornet.din.cz>

Hello,

I am looking for a Python library/framework to implement a simple CWMP (TR-069,
https://en.wikipedia.org/wiki/TR-069) server (<10 RPCs) in Python. Unlike usual
use (FWIK), the SOAP (1.1) in CWMP is used "bi-directionally" to allow the HTTP
server to call client's remote procedures:

a) HTTP request contains client's SOAP request, HTTP response carries server's
SOAP response (the usual "direction"),

b) HTTP request is empty (a challenge/call) and its HTTP response contains
_server's_ SOAP request, the next HTTP request then carries client's SOAP
response (the inverse direction).

Will you recommend me a Python SOAP library to implement an HTTP server working
in "both directions"? I suppose this SOAP-HTTP mapping is not completely
implemented yet in any Python library, so, please, just recommend me a library
that can be used as both general SOAP client and server easily...

Milan
