Api Request WSDL Python

I am trying to make an api connection via wsdl-soap in Python.

Here are the codes I used.

import zeep
wsdl = 'http://dev.gittigidiyor.com:8080/listingapi/ws/CategoryService?wsdl'
client = zeep.Client(wsdl=wsdl)


send_data=[{

'cat:getCategories' :[

{
'startOffSet' : 0,
'rowCount' : 4,
'withSpecs':'true',
'withDeepest':'true',
'withCatalog':'true',
'lang':'tr'
}
     ] } ]


print(client.service.getCategories(send_data))

The offical documentation suggests:

WSDL Address: http://dev.gittigidiyor.com:8080/listingapi/ws/CategoryService?wsdl

Service Method Signature: CategoryServiceResponse getCategories(int startOffSet, int rowCount, boolean withSpecs, boolean withDeepest, boolean withCatalog, String lang)

Request Example

<cat:getCategories>
   <startOffSet>0</startOffSet>
   <rowCount>4</rowCount>
   <withSpecs>true</withSpecs>
   <withDeepest>true</withDeepest>
   <withCatalog>true</withCatalog>
   <lang>tr</lang>
</cat:getCategories>

However I can't achieve to get any data from the source. I am getting errors like:

Traceback (most recent call last):
  File "/Users/maydin/Desktop/z.py", line 22, in <module>
    print(client.service.getCategories(send_data))

Any help (new library suggestions, code correction etc.) will be appriciated.

Thanks in advance!

Solution

  • I finally solved my own problem.. The thing that I have missed is that it was needing an authentication layer.

    Here are the codes for those who may need to solve similar problems.

    from requests import Session
from requests.auth import HTTPBasicAuth 
from zeep import Client
from zeep.transports import Transport

session = Session()
session.auth = HTTPBasicAuth('user_name', 'password')

client = Client('wsdl_url',
    transport=Transport(session=session))


print(client.service.service_name(parameter1,parameter2,parameter3..))

    Here is the source I made use of..
