SOAPpy: Expected to find node type 'Element' with name 'CountriesFetchingRequest'; Found node type 'Element' with name 'FetchCountries'
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'))
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
http://ws.aramex.net/ShippingAPI/v1/Service_1_0/FetchCountries";
name="CountriesFetchingRequest" message="tns:CountriesFetchingRequest" />
http://ws.aramex.net/ShippingAPI/v1/Service_1_0/FetchCountriesResponse";
name="CountriesFetchingResponse" message="tns:CountriesFetchingResponse" />
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)

{ '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)

would it be good to use 'rb' all the time?

aha. i've been doing this for years even with perl, and apparently it's
not necessary in perl either. i was influenced by shell.
this shell code:
* if [[ -n $report_mode ]] ; then*
*do_report*
* fi*
* exit 0*
is an example of why you want the last normally executed shell statement to
be "exit 0". if you omit the exit statement it in this example, and
$report_mode is not set, your shell program will give a non-zero return
code and appear to have terminated with an error. in shell the last
expression evaluated determines the return code to the os.
ok, i don't need to do this in python.

i chose to stick with ascii nul as the default field separator, but i added
a --field-separator option in case someone wants human readable output.
style question: if there is only one, possibly short statement in a block,
do folks usually move it up to the line starting the block?

*return*

I would first look at the source: "_ssl.c" (source of the Python module interfacing with OpenSSL) near line 1636. Likely, this only reports a problem reported by "OpenSSL". Next step would then be to look at the "OpenSSL" documentation or source to find out what the error reported by "OpenSSL" means. -- https://mail.python.org/mailman/listinfo/python-list

Could someone clarify? I have no experience with "SOAPpy", but with "suds" (another Python SAOP client). A "suds" client exposes two attributes "factory" and "service". You use the "factory" to create Python objects for types defined by the WSDL; you then set their attributes with standard Python means (maybe involving other "factory" calls). Finally you call the methods via the "service" attribute passing arguments of the appropiate type in the normal Python way. I suppose, it is similar with "SOAPpy". Looking at its documentation and/or its examples may provide you with the necessary details. Otherwise, you could also use "suds". -- https://mail.python.org/mailman/listinfo/python-list
