Finding Methods

Fragments extracted from Pywebsvcs-talk Digest, Vol 34, Issue 6

Also see http://lucasmanual.com/mywiki/SOAP

Below only lists available functions....

....
s=ServiceProxy(url,tracefile=sys.stdout)
....
from ZSI.schema import GED
print s._methods.keys()
for x in s._methods.keys():
        for i in s._methods[x][0].callinfo.inparams:
                print 'Inparameters',i.name,i.type,GED(*i.type)
        for i in s._methods[x][0].callinfo.outparams:
                print 'outparameters',i.name,i.type,GED(*i.type)

Try This

Fragments extracted from Pywebsvcs-talk Digest, Vol 34, Issue 5

Try this:

>>> from ZSI.ServiceProxy import ServiceProxy as sp
>>> s = sp("yoururl.wsdl")
>>> dir(s)

Ok. This does what? Connects me?

1. Now, there is a request function that I need to use. How can I find it? Where is it?

 dir(s)
['__doc__', '__init__', '__module__', '_asdict', '_cachedir', '_call',
'_force', '_kw', '_lazy', '_load', '_load_schema', '_methods', '_mod',
'_name', '_nullpyclass', '_port', '_pyclass', '_service', '_url',
'_wsdl']

2. The service I'm connecting to has a function that takes 3 arguments, so I assume somewhere I should be able to do:

processed_xml=somecallfunction(username='lucas',password='xyz',file='myxmlfile.xml')

How do I call that function? How do I list available "call functions"

? Anything else I need to do?

Actually the problem seems to be:

It looks like WCF hides some of their stuff in the WSDL, but they tell you
where it is with their import schemas:

<wsdl:types>
- <xsd:schema targetNamespace="http://tempuri.org/Imports">
  <xsd:import
schemaLocation="http://someurl.com/service.svc?xsd=xsd0"
namespace="http://tempuri.org/" />
  <xsd:import
schemaLocation="http://someurl.com/service.svc?xsd=xsd1"
namespace="http://schemas.microsoft.com/2003/10/Serialization/" />
  </xsd:schema>
</wsdl:types>

Is there a way I can get my ServiceProxy read that file?

 from ZSI.ServiceProxy import ServiceProxy as sp
>>>>> s = sp("yoururl.wsdl")

?????
It doesn't seem to follow the target schema?

Not sure who's fault was that....,I got the people to modify the wsdl
and now I can see the "submit and rate" function.

1. How do I use it ..From soappy examples I can see I could do the
following, but in zsi?

from SOAPpy import WSDL
>>> server = WSDL.Proxy('/path/to/your/GoogleSearch.wsdl')

server.methods.keys()                                  2
[u'doGoogleSearch', u'doGetCachedPage', u'doSpellingSuggestion']
>>> callInfo = server.methods['doGoogleSearch']
>>> for arg in callInfo.inparams:                          3
...     print arg.name.ljust(15), arg.type

and
results = server.doGoogleSearch(key, 'mark', 0, 10, False, "",
...     False, "", "utf-8", "utf-8")

2. I tried with zsi:

url='http:/someurl....com'

from ZSI.ServiceProxy import ServiceProxy as sp
s=sp(url)

f=open(somefile.xml','r')
file=f.readlines()
f.close()

 s.SubmitAndRate('myusername','mypassword','1234',file)

On the Usefulness of ZSI

Extracted from Pywebsvcs-talk Digest, Vol 30, Issue 3

Works fine for me, as far as client WSDL/SOAP is concerned.  But the
bigger problem is XSD files that turn quickly turn into monstrosities. I
use   Code Synthesis' xsd-tree for parsing xsd specifications and
serializing the data, then pack them in with ZSI to send them off to the
server.  I've tried Java (jaxb,jaxm), mono -C# (with Microsofts XSD),
gSoap and Perl soap::lite.   I found the java variations seriously over
engineered (a class file per element), (the mono XSD was seriously
deficient. Its /c to generate c++ didn't work on linux, and C# under
mono is really just a specification), and Perl soap::lite out of date
(didn't work with the .net services I had to deal with)   Had I had some
more time, I might have made gSoap work, but ZSI tackled the WSDL I had
to work with right out of the tarbox. And when something was unclear or
didn't work, I could step through with the python debugger to track it
down.   I work on linux.  If I had been developing on M$, I would have
used their stuff, but I still think I would stick with Code Synthesis
and C++ for parsing xsd.  It's a fantastic program with unbelievably
good support for an open source product, and works with Visual
Studio,too.

ZSI's support is ok, too.  The turnaround on questions is pretty slow.
But if you don't mind stepping through the code, you can usually fix the
problem yourself.  And there seem to be plenty of people using it.

Roger Evans

Having spent too much time recently looking at python/SOAP stuff I am
pretty sure ZSI is the only one out there that will go any way towards
handling the WSDL part for you.

I am more than willing for someone to correct me on this if I missed anything.

alphabetical order of 'self.attribute_typecode_dict'

This should be irrelevant, although order is important for canonicalization for an entirely different matter.

I think you could retain your ordering by replacing the underlying dict with your own dict subclass that maintains a list too.

	Topic._attrs = OrderDict()

Something like Collection, although obviously this is a bit old.

from ZSI.wstools.Utility import Collection

class Collection(UserDict):
     """Helper class for maintaining ordered named collections."""
     default = lambda self,k: k.name
     def __init__(self, parent, key=None):
         UserDict.__init__(self)
         self.parent = weakref.ref(parent)
         self.list = []
         self._func = key or self.default

     def __getitem__(self, key):
         if type(key) is type(1):
             return self.list[key]
         return self.data[key]

     def __setitem__(self, key, item):
         item.parent = weakref.ref(self)
         self.list.append(item)
         self.data[key] = item

     def keys(self):
         return map(lambda i: self._func(i), self.list)

     def items(self):
         return map(lambda i: (self._func(i), i), self.list)

     def values(self):
         return self.list

Upgrade to ZSI-2.1a and this package is no longer required.

http persistent connection

I think you can do this by using your own transport.

Here is the relevant code from client.py:

         self.h = transport(netloc, None, **self.transdict)
         self.h.connect()
         self.SendSOAPData(soapdata, url, soapaction, **kw)


So basically you'd need something like a Singleton that delegates to  
actual transports, so you can maintain these instances between soap  
calls and reuse the same transport when appropriate.

But I'm not sure about the rest, you'll need a transport that  
implements HTTP persistent connections.  Maybe twisted is a better bet  
than the python httplib.

ServiceProxy

> server = ServiceProxy(w, pyclass=True, tracefile=sys.stdout)

ZSI 2.0.0 as a whole supports complex type, but there's a serious bug
in ServiceProxy in 2.0.0 which prevents using it with asdict=False
(ServiceProxy in 2.0.0 doesn't have the pyclass keyword) [1]. I
suggest upgrading to 2.1a1 where the broken part of ServiceProxy has
been rewritten and now works.

[1] Specifically ServiceProxy._call always passes args or kwargs
through to binding.Send regardless of what asdict is set to, so that
with complex types calls to proxy methods complain that binding.Send
is getting tuples (i.e. args) or dicts (i.e. kwargs) instead of the
expected complex types.

ZSI Thread Safe?

I don't think so but threads in python are restricted by the GIL so  
all state is shared between threads.  So if you're changing an objects  
state all threads will "instantly" see it.  This is up to you to manage.

I have dowloaded/installed the following with no errors:
  Python 2.6

The Expat parser is included in Python 2.6 by default and is available
via xml.parsers.expat. ZSI will probably have to be updated to reflect
this -- perhaps it already has been? I would try ZSI 2.1a1 and then
ask again if the problem persists there

wsdl2py

Hi,

I'm having an issue with a type I have defined for my response in my wsdl.

One of the elements in my response is an xsd:list, which is just a list of strings seperated by space.
Here is the definition of the element:

<xsd:element name="linkedapplications" type="tnsb:linkedApplicationsList"/>

<xsd:simpleType name="linkedApplicationsList">
        <xsd:annotation>
            <xsd:documentation></xsd:documentation>
        </xsd:annotation>
        <xsd:list>
            <xsd:simpleType>
                <xsd:restriction base="xsd:string"></xsd:restriction>
            </xsd:simpleType>
        </xsd:list>
</xsd:simpleType>


I then run:
wsdl2py -b file.wsdl

And it auto generates my stubs.

Then testing the service it works fine if the <linkedapplications> element is empty.
But if it contains any values, such as <linkedapplications>value1</linkedapplications> or <linkedapplications>value1 value2</linkedapplications>

It throws the following error:

Traceback (most recent call last):
    resp = port.registerUserOrAddToGroup(req)

AttributeError: 'NoneType' object has no attribute 'text_to_data'


Is the definition of xsd:list allowed to by empty or do I have to specify enumerations?
I have seen examples that allow non enumerated xsd:list types.

Any help would be appreciated.

Cheers,
Jaie

GoogleSearch

Can you attach the wsdl file?

The params name and functions are defined in *_client.py
For example in GoogleSearch.wsdl:
I can import ZSI.ServiceProxy.ServiceProxy class and create a soap proxy or use wsdl2py tool. Three files are created:
GoogleSearch_client.py
GoogleSearch_server.py
GoogleSearch_types.py
In GoogleSearch_types.py we have:
The class:
class doGoogleSearch:
    def __init__(self, **kw):
        """Keyword parameters:
        key -- part key
        q -- part q
        start -- part start
        maxResults -- part maxResults
        filter -- part filter
        restrict -- part restrict
        safeSearch -- part safeSearch
        lr -- part lr
        ie -- part ie
        oe -- part oe
        """
        self.key =  kw.get("key")
        self.q =  kw.get("q")
        self.start =  kw.get("start")
        self.maxResults =  kw.get("maxResults")
        self.filter =  kw.get("filter")
        self.restrict =  kw.get("restrict")
        self.safeSearch =  kw.get("safeSearch")
        self.lr =  kw.get("lr")
        self.ie =  kw.get("ie")
        self.oe =  kw.get("oe")
and the typecode
doGoogleSearch.typecode = Struct(pname=("urn:GoogleSearch","doGoogleSearch"), ofwhat=[ZSI.TC.String(pname="key", aname="key", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TC.String(pname="q", aname="q", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TCnumbers.Iint(pname="start", aname="start", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TCnumbers.Iint(pname="maxResults", aname="maxResults", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TC.Boolean(pname="filter", aname="filter", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TC.String(pname="restrict", aname="restrict", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TC.Boolean(pname="safeSearch", aname="safeSearch", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TC.String(pname="lr", aname="lr", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TC.String(pname="ie", aname="ie", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True), ZSI.TC.String(pname="oe", aname="oe", typed=False, encoded=None, minOccurs=1, maxOccurs=1, nillable=True)], pyclass=doGoogleSearch, encoded="urn:GoogleSearch")

All you need is here, the params names and the type( String, Boolean, ...)

Or I can use ServiceProxy:

for n in s.doGoogleSearch.callinfo.inparams: print n.name,n.type
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')

And the outparams:
for n in s.doGoogleSearch.callinfo.outparams: print n.name,n.type

1. How do I find out the params names?

http://lucasmanual.com/mywiki/SOAP

Below only lists available functions....
_________________________________________
....
s=ServiceProxy(url,tracefile=sys.stdout)
....
from ZSI.schema import GED
print s._methods.keys()
for x in s._methods.keys():
       for i in s._methods[x][0].callinfo.inparams:
               print 'Inparameters',i.name,i.type,GED(*i.type)
       for i in s._methods[x][0].callinfo.outparams:
               print 'outparameters',i.name,i.type,GED(*i.type)


2. . How can I figure out what I suppose to send to 'SubmitAndRate'?
3. I see that the response is a dictionary {'_SubmitAndRateReponse'}.
How would I find that out problematically from outparamas?

Thanks,
Lucas
