I am trying this code to fetch data from wsdl.
Querying the website for the zipid("60630") works fine but in my code it gives the error as
"Invalid ZIP"
wsdlFile = 'http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl'
wsdlObject = WSDL.Proxy(wsdlFile)
wsdlObject.show_methods()
zipid = "60630"
result = wsdlObject.GetCityWeatherByZIP(ZIP=zipid)
print result[1]
Can someone please help whats wrong here and why the code is not working correctly.
Thanks !!!
The problem probably is that your client sends a request the server doesn't understand. Seems you're using SOAPpy, that's the request it sends when I try it:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/1999/XMLSchema"
>
<SOAP-ENV:Body>
<GetCityWeatherByZIP SOAP-ENC:root="1">
<v1 xsi:type="xsd:string">60630</v1>
</GetCityWeatherByZIP>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
In comprison when using suds:
from suds.client import Client
cli = Client("http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl")
cli.service.GetCityWeatherByZIP(ZIP=60630)
it produces:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/"
xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<ns1:Body>
<ns0:GetCityWeatherByZIP>
<ns0:ZIP>60630</ns0:ZIP>
</ns0:GetCityWeatherByZIP>
</ns1:Body>
</SOAP-ENV:Envelope>
(captured using wireshark)
The second request returns a valid result from the server.
I don't know SOAPpy well enough to suggest a way to fix this, but maybe you could consider switching your client library to suds.

I need some help with suds request in python.
Generated XML request looks like this
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Header>
<m:ExternalApiHeader xmlns:m="http://www.GlobalBettingExchange.com/ExternalAPI/" version="" languageCode="" username="" password="" applicationIdentifier=""/>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<m:GetEventSubTreeWithSelections xmlns:m="http://www.GlobalBettingExchange.com/ExternalAPI/">
<m:getEventSubTreeWithSelectionsRequest WantPlayMarkets="true">
<m:EventClassifierIds>2147483647</m:EventClassifierIds>
</m:getEventSubTreeWithSelectionsRequest>
</m:GetEventSubTreeWithSelections>
</SOAP-ENV:Body>
I have created python script and the only thing I can't figure out how to pass the value EventClassifierIds, which is 2147483647
import suds
url = 'http://api.betdaq.com/v2.0/API.wsdl'
client = suds.client.Client(url)
#prepare headers
token=client.factory.create('ExternalApiHeader')
token._version='2'
token._languageCode='en'
token._username=''
token._password=''
client.set_options(soapheaders=token)
#reguest
result = client.service.GetEventSubTreeWithSelections('false')
print result
I'm a newb when it comes to soap, but here is what I have. If I make a soap call with perl's SOAP::Lite library, everything is cool. When I make the same call with suds, I get an error from the server.
Here is the working xml generated by the perl call:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:urn="urn:webservicesapi"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Body>
<urn:getChassis xsi:nil="true" />
</soap:Body>
</soap:Envelope>
Making the same call with suds, I get this xml generated
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:ns0="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ns1="urn:webservicesapi"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<ns0:Body>
<ns1:getChassis/>
</ns0:Body>
</SOAP-ENV:Envelope>
The error produced with the server is: <ErrorCode>43</ErrorCode><Description>Start and end tag names don't match</Description>
If I use a soap plugin with my browser, I can replicate this. If I change the body to:
<SOAP-ENV:Body>
<urn:getChassis xsi:nil="true" />
</SOAP-ENV:Body>
The call works just fine.
So, I either need to know how to change the prefix for Body and urn: or I need to understand why the Start and end tag names don't match?
I understand I can use from suds.plugin import MessagePlugin to manipulate the xml before it is sent, but I am at a loss here.
Any help or advice would be greatly appreciated.
OK. Got it to work.
class EnvelopeFixer(MessagePlugin):
def marshalled(self, context):
context.envelope.getChild('ns0:Body').setPrefix('ns1')
Then I called the plugin when creating the client object
client = Client(WSDL_LOCATION, transport=t, location=url, plugins=[EnvelopeFixer()])
I am having a problem with python suds trying to create a proper Suds XML Request:
This is my suds Code (after a few trials):
from suds import *
from suds.client import Client
from suds.transport.http import HttpAuthenticated
import logging
url = 'http://ws/webservices/600/ws.asmx?wsdl'
soap_client = Client(url, location='http://ws/webservices/600/ws.asmx')
soap_client.set_options(port='GatewayWebServiceSoap')
person = soap_client.factory.create('checkIfExists')
person.UserID = 'toni.tester#anywhere.at'
person.SessionID = ''
eventService = soap_client.service.CustomerService(person)
print 'last received:'
print soap_client.last_received()
print '-------------------------------------'
print 'last sent:'
print soap_client.last_sent()
This is what my suds sends:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="http://service.example.at/gateway/v6.00" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<ns1:Body>
<ns0:Service>
<ns0:Service>
<ns0:SessionID></ns0:SessionID>
<ns0:UserID>toni.tester#anywhere.at</ns0:UserID>
</ns0:Service>
</ns0:Service>
</ns1:Body>
</SOAP-ENV:Envelope>
And this is what the WebService expects:
<?xml version="1.0" encoding="UTF-8"?>
<GATEWAY xmlns="urn:service-example-at:gateway:v4-00">
<Service>
<checkIfExists>
<SessionID></SessionID>
<UserID>test</UserID>
</checkIfExists>
</Service>
</GATEWAY>
My Questions:
How can I change SOAP-ENV:Envelope -> GATEWAY
How can I remove the namespaces ns1, ns0?
How can I remove the Body
If you really don't care about WSDL and stuff you can easily write request generator yourself since xml request is just a string template. That's what i did for my soapy needs.
I'm trying to access a function defined in my WSDL from HP Server Automation, I'm able to get servers/etc, but not able to pull anything that takes a server reference specifically via SOAPpy.
import SOAPpy
from SOAPpy import WSDL
from SOAPpy import structType
SOAPpy.Config.debug=1
server = WSDL.Proxy('ServerService.wsdl')
serverRef = structType(name='self', typed=0)
serverRef._addItem('id',SOAPpy.longType(19250001))
print server.getCustAttr(serverRef,key='HPSW_ED_win32_diskspace',useScope=False)
The SOAP envelope generated from this code looks like this:
*** Outgoing SOAP ******************************************************
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsd2="http://www.w3.org/2000/10/XMLSchema"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/1999/XMLSchema"
>
<SOAP-ENV:Body>
<ns1:getCustAttr xmlns:ns1="http://server.opsware.com" SOAP-ENC:root="1">
<xsd:self>
<id xsi:type="xsd2:long">19250001</id>
</xsd:self>
<useScope xsi:type="xsd:boolean">False</useScope>
<key xsi:type="xsd:string">HPSW_ED_win32_diskspace</key>
</ns1:getCustAttr>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
And it should look like this ( runs successfully via SOAPUI):
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://server.opsware.com">
<soapenv:Header/>
<soapenv:Body>
<ser:getCustAttr soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<self xsi:type="ser:ServerRef">
<id xsi:type="xsd:long">19250001</id>
</self>
<key xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">HPSW_ED_win32_diskspace</key>
<useScope xsi:type="xsd:boolean">False</useScope>
</ser:getCustAttr>
</soapenv:Body>
</soapenv:Envelope>
I believe the issue is that the xsi:type="ser:ServerRef" is not set, and not really sure how to do that with SOAPpy...
there are two different types of soap styles(RPC literal and Document literal),looks like the mentioned soap server just supports RPC
i saw this problem with soappy and suds. after some tests and benchmarks,i found the problem.
ASP.NET and soappy. you need produce a rpc envelop with python instead document literal envelop style.
just ZSI(The Zolera Soap Infrastructure) works with asp.net and complex types.
this command generates the client proxy for you:
wsdl2py http://terraservice.net/TerraService.asmx?WSDL
and you can import generated modules in your code and use the web methods.
I have WSDL file, using that i wanted to make soap request which will look exactly like this --
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<AuthSoapHd xmlns="http://foobar.org/">
<strUserName>string</strUserName>
<strPassword>string</strPassword>
</AuthSoapHd>
</soap:Header>
<soap:Body>
<SearchQuotes xmlns="http://foobar.org/">
<searchtxt>string</searchtxt>
</SearchQuotes>
</soap:Body>
</soap:Envelope>
To sovle this, i did this
>> from SOAPpy import WSDL
>> WSDLFILE = '/path/foo.wsdl'
>> server = WSDL.Proxy(WSDLFILE)
>> server.SearchQuotes('rel')
I get this error
faultType: <Fault soap:Server: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.NullReferenceException: Object reference not set to an instance of an object.
The i debugged it and got this
*** Outgoing SOAP ******************************************************

SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"

</SearchQuotes>
</SOAP-ENV:Body>

We can see it doesn't contain any header. I think that WSDL file has some bug.
Now, can anyone suggest me how to add header to this outgoing soap request.
Any sort of help will be appreciated. Thanks in advance
Not tested, but I believe you can use the method the docs suggest to add soap headers, i.e., make and prep a SOAPpy.Header instance, then use server = server._hd (hd) to get a proxy equipped with it (though in your case that does seem to be a workaround attempt to broken WSDL, as you say -- might it be better to fix the WSDL instead?).
