Parsed value of zeep.exceptions.Fault.detail if tehere is element discription in wsdl

[Vick-edit]

Сonfiguration:

1. python == 3.5
2. zeep == 1.3.0

Action:

1. Create corrcet zeep.Client object
2. Call to corrcet SOAP method with not valid data (incorrect format, for example)
3. Wrap code above in try ... except zeep.exceptions.Fault as error:
4. Get error.detail

try:
	client = Client('http://www.webservicex.net/ConvertSpeed.asmx?WSDL')
	client.service.ConvertSpeed( 'Not Correct Data', 'kilometersPerhour', 'milesPerhour')

except Fault as error:
	foo = error.detail

Result:
I get lxml.etree._Element that need to be parsed, but I have format description for this object in wsdl (in my case).

Suggestion
Add to Fault class "detail_pased" property that will be stored value like service.Method() format if it possible restore by wsdl's types/elements.

Where detail are builds add something like this:
detail_pased=__tryParse(detail) # None or parsed

I can look at this but I need an example wsdl (or better yet a runnable example script) to implement this.

Seems that webservicex.net is down now, so some examples from local server (sorry):

WSDL description
ejbca_wsdl_xml.txt

Error message examples (sorry formatted already):
error1.txt
error2.txt

So for example detail in SOAP message is:

   <detail>
    <ns1:WaitingForApprovalException xmlns:ns1="http://ws.protocol.core.ejbca.org/">
     <approvalId xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ns2="http://ws.protocol.core.ejbca.org/" xsi:type="xs:int">0</approvalId>
    </ns1:WaitingForApprovalException>
   </detail>

Obviously this is a late comment on this issue, so maybe it's a new addition or it's WSDL-specific, but you could just use error.code to achieve an error-specific action when using zeep.exceptions.Fault.

[gnishad9573]

try:
session.auth = HttpNtlmAuth(username,password)
transport = Transport(session=session)
client = Client(url,transport=transport)
client.service.CI_Z_SP_PERS_DTL_CI_G(EMPLID="001670")
except zeep.exceptions.Fault as fault:
print fault.message
print fault.code
print fault.actor
print fault.detail

i am getting error like
null
SOAP-ENV:Server
None
<Element detail at 0x7f7e5981efc8>

[drussell393]

print fault.message
print fault.code
print fault.actor
print fault.detail

i am getting error like
null
SOAP-ENV:Server
None
<Element detail at 0x7f7e5981efc8>

That's not an error. That's the printouts of what you're asking for.

fault.message is null
fault.code is SOAP-ENV:Server
fault.actor is None
fault.detail is the element detail object that you get there.

[gnishad9573]

when i was to access method then its giving error like
zeep.exceptions.Fault: null

[gnishad9573]

from zeep import Client
from zeep.transports import Transport
from requests_ntlm import HttpNtlmAuth
from requests import Session
session = Session()
username = ""
password = ""
url = ""
session.auth = HttpNtlmAuth(username,password)
transport = Transport(session=session)
client = Client(url,transport=transport)
client.service.CI_Z_SP_PERS_DTL_CI_G(EMPLID="001670")
###Giving error
zeep.exceptions.Fault: null

@gnishad9573 all you need to do is something like this to get the data you want:

client.wsdl.types.deserialize(fault.detail)

This will return the proper class. I think zeep just doesn't try to transform the detail in a Fault.

[apollo13]

I think

python-zeep/src/zeep/wsdl/bindings/soap.py

Line 299 in 1ac9e7a

detail=fault_node.find("detail"),

should do the conversion according to the defined faults in the WSDL. Sadly I cannot share mine, I'll try to provide a testcase though.

[apollo13]

This is a testcase that should display how it ends up:

def test_soap11_process_error_with_fault_in_wsdl():
    client = Client("tests/wsdl_files/soap.wsdl")

    response = load_xml(
        """
        <soapenv:Envelope
            xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
            xmlns:stoc="http://example.com/stockquote.xsd">
          <soapenv:Body>
            <soapenv:Fault>
              <faultcode>fault-code</faultcode>
              <faultstring>fault-string</faultstring>
              <detail>
                <stoc:Fault1>
                  <stoc:message>TestMessage</stoc:message>
                </stoc:Fault1>
              </detail>
            </soapenv:Fault>
          </soapenv:Body>
        </soapenv:Envelope>
    """
    )

    binding = bindings.Soap11Binding(
        wsdl=client.wsdl, name=None, port_name=None, transport=None, default_style=None
    )
    try:
        binding.process_error(response, None)
        assert False
    except Fault as exc:
        # This is what the result should imo contain somehow
        detail_decoded = client.wsdl.types.deserialize(exc.detail[0])
        print(detail_decoded, type(detail_decoded))
        # It's not a zeep object though
        assert exc.detail[0].__class__.__name__ == "Fault1"

I've found this code which suggests what might be missing:

python-zeep/src/zeep/wsdl/bindings/soap.py

Line 355 in 1ac9e7a

# TODO: We should use the fault message as defined in the wsdl.

-- the same applies to the soap 1.1 bindings

@mvantellingen Could you chime in here to the latest comments I provided? (Once again I'll happily provide the patch, but I'd need some guidance)
