SOAPpy: Expected to find node type 'Element' with name 'CountriesFetchingRequest'; Found node type 'Element' with name 'FetchCountries'

[vek.m1234 at gmail.com]

I'm messing with SOAP, trying to write a small library to handle stuff I buy from Aramex (shipper). I'm learning XML/SOAP and I'm familiar with RPC from C (Stevens) but no other relevant experience. If this is incredibly dumb just ignore it since I'll probably figure it out eventually.

I'm trying to get a list of countries by calling the CoutriesFetchingRequest method - this is documented here:
http://www.aramex.com/developers/aramex-apis/47442/Location-Services-API
http://www.aramex.com/content/uploads/109/232/46790/aramex-location-api-manual.pdf

It takes as its arguments a 'ClientInfo' data-structure and 'Code' which is a string.

There is also a 'FetchCountries' method with an 'input' and 'output' something.
However python was more clear, print server.show_methods():

Method Name: FetchCountries 
   In #0: parameters  ((u'http://ws.aramex.net/ShippingAPI/v1/', u'CountriesFetchingRequest'))
<SNIP>

The trouble is I don't understand how to call 'CoutriesFetchingRequest' or pass it to FetchCountries. Could someone clarify?


The WSDL for Aramex has this:
http://www.aramex.com/content/uploads/109/232/46790/location-api-wsdl.zip
    <wsdl:operation name="FetchCountries">
      <wsdl:input wsaw:Action="http://ws.aramex.net/ShippingAPI/v1/Service_1_0/FetchCountries" name="CountriesFetchingRequest" message="tns:CountriesFetchingRequest" />
      <wsdl:output wsaw:Action="http://ws.aramex.net/ShippingAPI/v1/Service_1_0/FetchCountriesResponse" name="CountriesFetchingResponse" message="tns:CountriesFetchingResponse" />
    </wsdl:operation>


      <wsdl:input name="CountriesFetchingRequest">
        <soap:body use="literal" />
      </wsdl:input>

My python code:
#!/usr/bin/python
import xml, fpconst, logging
from SOAPpy import WSDL
from suds.client import Client

logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)

foo = { 'AccountCountryCode' : 'JO', 'AccountEntity' : 'AMM', 'AccountNumber' : '20016', 'AccountPin' : '331421', 'UserName' : 'testingxxx at aramex.com', 'Password' : 'R123456789$r', 'Version' : 'v1.0', 'Source' : '', 'Transaction' :  { 'Reference1' : '001', 'Reference2' : '002', 'Reference3' : '003', 'Reference4' : '004', 'Reference5' : '005' } }

wsdl_file = '/home/veek/location-api-wsdl/Location-API-WSDL.wsdl'

server = WSDL.Proxy(wsdl_file)
print server.methods.keys()
print dir(server)
print server.show_methods()
callInfo = server.methods['FetchCountries']
print type(callInfo)
print dir(callInfo)

for arg in callInfo.inparams:
    print arg.name.ljust(15), arg.type
server.namespace = 'http://ws.aramex.net/ShippingAPI/v1/'
x = server.FetchCountries.CountriesFetchingRequest(foo)

The output i get is:
[u'FetchCountries', u'FetchCountry', u'ValidateAddress', u'FetchCities', u'FetchOffices']
