SOAP request with href attribute

Asked by Ales Klimsa on 2012-02-16

Hi Jakob,
please take a look at this SOAP request:

Please notice using href attribute in Contact object:
<item xsi:type="ns1:Contact" id="ref1">


<contacts SOAP-ENC:arrayType="ns1:Contact[1]" xsi:type="ns1:ArrayOfContact">
<item href="#ref1"/>

And when I want access this attribute:
customer->contacts[0]->contactType->ID (this object is represented by <item href="#ref1"/>), I got this error: AttributeError: 'dict' object has no attribute 'ID'

In this contactType attribute isn't stored my object contactType (
<contactType xsi:type="ns1:ContactType">
<ID xsi:type="xsd:long">3</ID>
<Name xsi:type="xsd:string">email</Name>
but there is: {'doc': 'Contact type object', 'type': <class 'src.dto.ContactType.ContactType'>, 'nullable': True}

Could you help me please?

hi Ales,

Sorry for the rather long response time :-)

hmm, that seems odd. Can you send a service stub that I can try this with?

Hi Jakob, don't suffer for the late reply, I had weeked too ;)
But i'm not sure what you mean the service stub :(

Thanks for clarify

Hi Ales.

Small Ladon service that can produce the error :-)

But, the way how to assembly the request on client side is important. Here is a call example in PHP:

The problem occurs when I use for each instance of Contact ($con1, $con2) same instance of ContactType ($ct)

When I log this on the server side in test method: logging.debug(customer.contacts[1].contactType.ID)

This is the result: DEBUG:root:{'doc': 'ID of contact type', 'type': <class 'int'>, 'nullable': True}

Hi Ales.

Ok I tried using suds, I can't make it work either, can you maybe send the service module source, so I can use it for testing?

jsgaarde (jakob-simon-gaarde) said : #6

Oh - wait, I saw that the error I was recieving from the service you have setup, was due to you referencing index 1 in the list of customers. I added one more customer and it worked.

I used suds to produce the request.

Here is the client code:

Here is the request:

And the output:
Result: test

So, isn't it just your php-soap library, that is producing bad requests?

I believe that the problem is caused using ID and HREF attributes in SOAP request. You can see it in my example:

First contact

<item xsi:type="ns1:Contact" id="ref1">

<contacts SOAP-ENC:arrayType="ns1:Contact[1]" xsi:type="ns1:ArrayOfContact">
<item href="#ref1"/>

And the object which is represented by this code (<item href="#ref1"/>) aren't stored values of Contact with id = "ref1", but there is: {'doc': 'Contact type object', 'type': <class 'src.dto.ContactType.ContactType'>, 'nullable': True}

If you insepct your SOAP request, there is no ID/HREF attributes used.

Maybe ladon isn't able to parse this attributes

jsgaarde (jakob-simon-gaarde) said : #8

Hi Ales.

I'm a little confused... Why does your SOAP client put href into the <item> element, and what is it you expect Ladon to do?

/ Jakob

Ales Klimsa (ales-klimsa) said : #9

Hi Jakob,
element <item href="#ref1"/> is reference to the previous contact element <item xsi:type="ns1:Contact" id="ref1">...</item> with id="ref1". Because both contact object are identicaly (have same values in all attributes). I don't know why "my" SOAP client is using this shorthand.
My expecting from ladon is that ladon replace element <item href="#ref1"/> by the element <item xsi:type="ns1:Contact" id="ref1">...</item>.

I'm not sure, if using id/href attributes is valid according to SOAP specification. But we are using standard SOAP extension for PHP:, which is widely used, so I thought it wouldn't be bad, if ladon supports this id/href shorthands.

What you mean?


jsgaarde (jakob-simon-gaarde) said : #10

Hi Ales.

Just had a look at the SOAP 1.1 specification. It turns out that using href in item elements actually is legal. So I will look at implmenting this soon.
