Y'all,
Problem: Reading complex data types returned from WSDL
I'll present this in 3 sections.
1. Output of WSDL parser on Google API
2. Output of WSDL parser on Custom API
3. WSDL parser code
1. Output of WSDL parser on Google API
So far I have a very simple WSDL reader which gathers the commnads and
arguments of the WSDL. For instance, running against the google API
generates:
Commands: [u'doGoogleSearc h', u'doGetCachedPa ge',
u'doSpellingSug gestion']
Arguments for "doGoogleSearch ":
key (u'http://www.w3.org/2001/XMLSchema', u'string')
q (u'http://www.w3.org/2001/XMLSchema', u'string')
start (u'http://www.w3.org/2001/XMLSchema', u'int')
maxResults (u'http://www.w3.org/2001/XMLSchema', u'int')
filter (u'http://www.w3.org/2001/XMLSchema', u'boolean')
restrict (u'http://www.w3.org/2001/XMLSchema', u'string')
safeSearch (u'http://www.w3.org/2001/XMLSchema', u'boolean')
lr (u'http://www.w3.org/2001/XMLSchema', u'string')
ie (u'http://www.w3.org/2001/XMLSchema', u'string')
oe (u'http://www.w3.org/2001/XMLSchema', u'string')
With this it is easy to create a command and send it the proper value
types. You still have to know what each does, but the type is
obvious.
2. Output of WSDL parser on Custom API
When I run this against my company's custom API, though, I see the
comnmands fine:
Commands: [u'getCustomerIn formation']
But the argument names and types look like:
getCustomerInfo rmationRequest
(u'java:com.pro ductname.produc tversion.soap', u'ge
tCustomerInform ation')
Now, according to my developers this is because they treat each api
call like a separate document which returns several values, whereas
the google API treats each as a separate data type (string).
The WSDL would look like this:
<xsd:complexTyp e name="CustomerI nfo">
<xsd:sequence >
<xsd:element type="xsd:strin g" name="email" minOccurs="1"
maxOccurs="1" nillable="true" />
<xsd:element type="xsd:strin g" name="firstName " minOccurs="1"
maxOccurs="1" nillable="true" />
<xsd:element type="xsd:strin g" name="lastName" minOccurs="1"
<xsd:element type="xsd:strin g" name="phoneNumb er" minOccurs="1"
maxOccurs="1" nillable="true" />
</xsd:sequence>
</xsd:complexType >
Can I somehow parse the response from the WSDL to get at the atomic
data types? The goal is to do this programmaticall y to provide a GUI
front end for the APIs for testing.
3. WSDL reader
#!/usr/bin/env python
#http level debugging
import httplib
httplib.HTTPCon nection.debugle vel = 1
from SOAPpy import WSDL
server = WSDL.Proxy('d:/googleapi/GoogleSearch.ws dl')
print server.methods. keys()
callInfo = server.methods['doGoogleSearch ']
for arg in callInfo.inpara ms:
print arg.name.ljust( 15), arg.type
Any help at all would be appreciated.
Sincerely,
Nick
