Suds -> client and for ? the server side ?
by Alexis Michon 27 May '09

27 May '09

Hello, My question is a little bit off the topic. Actually, i am programming some webservices and for the client part, Suds makes a very great job. This is a very userfriendly tool, a very good job have been done by developpers, thanks you guy ! But for the server side, i haven't found any tools like Suds. Do you know a python library that could make the server side of a webservice infrastructure ? Something that could be use with mod_python and apache. I found and tried ZSI, but it isn't enough and it seems to be dead. So, what library do you use in your infrastructure ? Thanks you in advance for your help. ++ Alexis -- Alexis MICHON CNRS, France IBCP, Institut de Biologie et Chimie des Proteines Mail : alexis.michon(a)ibcp.fr Tel : 04.72.72.26.46 Empreinte : 8FDA 1594 2C18 EEDA 681E 8A6D 56EF F0A0 6F06 892A

optional elements
by Yi Qiang 22 May '09

22 May '09

Hi, The WSDL I am trying to use suds with is a bit annoying in that it defines certain elements as REQUIRED but read only. For example, it will have something like the following: <s:element minOccurs="1" maxOccurs="1" name="fDefault" type="s:boolean"/> So when suds generates the SOAP request, it will put the following as a default: <ns0:fDefault xsi:nil="true"/> Then the server complains that this is not valid. If I set this to say "true" or "false", the server complains that this field is read only. The only way I've been able to work around this is to download the WSDL from the server, make that element optional by changing "minOccurs" to 0. Is there anyway to tell suds to not put default elements? I.e., only create XML elements that I specifically ask for? Thanks, Yi

ImportDoctor or SAX?
by Zhiwu Xie 22 May '09

22 May '09

Newbie here, would appreciate your help and/or hint. Not sure if it's because I didn't use ImportDoctor properly or because it's a SAX parser so it didn't reach the scheme for the namespace 'urn:theplatform-com:v4/base/' before trying to parse it, or it's the WSDL file (http://admin.theplatform.com/API/urn:service.wsdl) that's wrongly formed. Thanks a lot, Zhiwu >>> from suds.xsd.doctor import * >>> imp = Import('http://www.w3.org/2001/XMLSchema') >>> imp.filter.add('urn:theplatform-com:v4/base/') >>> doctor = ImportDoctor(imp) >>> url = 'http://admin.theplatform.com/API/urn:service.wsdl' >>> client = Client(url, schemadoctor=doctor) Traceback (most recent call last): File "<pyshell#9>", line 1, in <module> client = Client(url, schemadoctor=doctor) File "C:\Python25\Lib\site-packages\suds\client.py", line 106, in __init__ self.wsdl = Definitions(url, options) File "C:\Python25\Lib\site-packages\suds\wsdl.py", line 193, in __init__ self.build_schema() File "C:\Python25\Lib\site-packages\suds\wsdl.py", line 255, in build_schema self.schema = container.load() File "C:\Python25\Lib\site-packages\suds\xsd\schema.py", line 92, in load child.dereference() File "C:\Python25\Lib\site-packages\suds\xsd\schema.py", line 294, in dereference midx, deps = x.dependencies() File "C:\Python25\Lib\site-packages\suds\xsd\sxbasic.py", line 783, in dependencies raise TypeNotFound(qref) TypeNotFound: Type not found: '(BusinessObject, urn:theplatform-com:v4/base/, )'

schema doctor
by Jeff Ortel 19 May '09

19 May '09

All, The schema /doctor/ was added in r512 and released in the 0.3.6 beta. The module defines the Doctor interface and provides one stock implementation. The ImportDoctor is designed to fix schemas that are missing imports. Those of you using locally stored and fixed wsdls containing or importing schemas that are missing imports such as: <xs:import namespace="http://schemas.xmlsoap.org/soap/encoding/"/> and <xs:import namespace="http://www.w3.org/2001/XMLSchema"/> can now use the schema doctor to patch these schema(s) at runtime and go back to using the wsdl provided by the service provider. Also, the Doctor interface is designed to be user extensible. Suds users can write there own doctor classes to do pretty much whatever is needed to make schema(s) work. See https://fedorahosted.org/suds/wiki/Documentation#FIXINGBROKENSCHEMAs for examples and more details. Regards, Jeff

multipart reply with binary
by Daryl Daly 19 May '09

19 May '09

I am new to suds and fairly new to SOAP in general. I am trying to use suds to interact with JasperServer's SOAP server. versions: Python 2.5 suds 0.3.5 (also tried 0.3.6) I am able to connect to the SOAP server and use simple commands but when I try to use the runReport method I get: xml.sax._exceptions.SAXParseException: <unknown>:2:6: not well-formed (invalid token) It seems that the server is returning a multipart reply. One part of it is binary (an image). My first question is, should suds be able to handle this? Here the code I am using: from suds.client import Client client = Client('http://mxp.norco.com:8080/jasperserver/services/repository?wsdl',username='jasperadmin',password='xxxxxx') result = client.service.runReport('<request operationName="runReport" locale="en"><argument name="RUN_OUTPUT_FORMAT">HTML</argument><resourceDescriptor name="" wsType="" uriString="/reports/sales/cust_sales_chart" isNew="false"><label>null</label><parameter name="cust_no">1dunbcyc</parameter></resourceDescriptor></request>') If needed I can include the full TCP conversation but it is rather long. Here is just the beginning part of the reply: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: multipart/related; type="text/xml"; start="<454B124F1FC5659C9A0D323DE8BD639C>"; .boundary="----=_Part_12_32920944.1242418155865" Date: Fri, 15 May 2009 20:09:15 GMT Connection: close ------=_Part_12_32920944.1242418155865 Content-Type: text/xml; charset=UTF-8 Content-Transfer-Encoding: binary Content-Id: <454B124F1FC5659C9A0D323DE8BD639C> <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><ns1:runReportResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://axis2.ws.jasperserver.jaspersoft.com"><runReportReturn xsi:type="xsd:string"><?xml version="1.0" encoding="UTF-8"?> <operationResult version="2.0.1"> .<returnCode><![CDATA[0]]></returnCode> </operationResult> </runReportReturn></ns1:runReportResponse></soapenv:Body></soapenv:Envelope> ------=_Part_12_32920944.1242418155865 Content-Type: image/png Content-Transfer-Encoding: binary Content-Id: <img_0_0_0> .PNG [...SNIP...] Thanks, Daryl.

help with mlb.com wsdl's again
by Matthew 12 May '09

12 May '09

Hi guys, Looks like mlb.com's wsdl's are a little iffy once again. Last time it was their MediaService.wsdl. This time I'd like to use their IdentityPointService.wsdl to perform authentication. The wsdl in question is here: http://www.mlb.com/flash/mediaplayer/v4/wsdl/IdentityPointService.wsdl and it's xsd here: http://www.mlb.com/flash/mediaplayer/v4/wsdl/IdentityPointService.xsd Here's the code I'm trying: import sys import logging logging.basicConfig(level=logging.INFO) import suds from suds.client import Client from suds.xsd.sxbasic import Import logging.getLogger('suds.client').setLevel(logging.DEBUG) url = 'file:///home/matthew/mlb-2009/sudsy/IdentityPointService.wsdl' client = Client(url) And the error I get: >>> client = Client(url) Traceback (most recent call last): File "<stdin>", line 1, in ? File "build/bdist.linux-i686/egg/suds/client.py", line 109, in __init__ File "build/bdist.linux-i686/egg/suds/servicedefinition.py", line 52, in __init__ File "build/bdist.linux-i686/egg/suds/servicedefinition.py", line 132, in paramtypes File "build/bdist.linux-i686/egg/suds/xsd/sxbasic.py", line 156, in resolve suds.TypeNotFound: Type not found: '(identityPoint, http://services.bamnetworks.com/registration/types/1.4, )' I don't have any control over their WSDL/XSD so if you guys can tell me what lines need to change, I will use local copies of these files using file:// url's to make requests. Thanks, Matthew

list (apparently) being sent as '[]' instead of []
by Tom von Schwerdtner 06 May '09

06 May '09

Greetings folks, I'm trying to figure out whose fault this is and would appreciate some input. In short, I have a service call that takes a FilterRules type as an argument (pulled from the client factory), which is configured as follows: >>> print filter (FilterRules){ marketClassIds[] = <empty> vehicleTypes[] = <empty> } The spec for this service says that marketClassIds should be an array of integers, however when I assign it to an array as follows: >>> filter.marketClassIds = [1, 2] >>> print filter (FilterRules){ marketClassIds[] = 1, 2, vehicleTypes[] = <empty> } and I submit it, I get the following error: suds.WebFault: Server raised fault: 'JAXRPC.TIE.01: caught exception while handling request: deserialization error: java.lang.NumberFormatException: For input string: "[1, 2]"' FWIW, I have seen (but not executed, yet) PHP code for the service that simply assigns an empty array to marketClassIds, doing so with python results in a similar input string error. So it seems the server is interpreting the marketClassIds as the __str__ of the array, and not as an actual array. If I set marketClassIds to a non-array integer, eg: filter.marketClassIds = 1 It works. So, my question is, am I doing something wrong, is suds doing something wrong, or is the server I'm hitting doing something wrong? Any tips on further debugging this? I'd love to provide working samples but unfortunately this is a proprietary service. I can give more information if needed, I'm not too familiar with SOAP so I wasn't sure what to provide. Regards, Tom
