how to make a axis2-client for a python webservice server-side
by 贾晓磊 06 Dec '11

06 Dec '11

Hi, all: I was doing something about webservice. What a need to do is using a axis2-client to invoke a webservice developed by python. I tried to provide kinds of webservice server-side, and invoke them by axis2-client. While, all is failed. In the contents below, I provide the wsdl, axis2 client-side and the server-side made by python. Hope some axis2 experts can give me some points. Thanks ahead. Method 1: # server-side: tornadows import logging import tornado.httpserver import tornado.ioloop import tornado.web from tornadows import soaphandler from tornadows import webservices from tornadows import xmltypes from tornadows.soaphandler import webservice from tornado.options import define, options define('mode', default='deploy') define('port', type=int, default=8000) options['logging'].set('warning') class SMSService(soaphandler.SoapHandler): @webservice(_params=xmltypes.Integer,_returns=xmltypes.Integer) def getPrice(self,a): return 1987 if __name__ == '__main__': service = [('SMSService',SMSService)] app = webservices.WebService(service) ws = tornado.httpserver.HTTPServer(app) ws.listen(options.port) logging.warn("SMSService running on: localhost:%d", options.port) tornado.ioloop.IOLoop.instance().start() # wsdl: you can find it in web browser through the url “ http://172.16.2.46:8000/SMSService?wsdl” <wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://127.0.1.1:8000/SMSService/getPrice" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd=" http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="SMSService" targetNamespace="http://127.0.1.1:8000/SMSService/getPrice"> <wsdl:types> <xsd:schema targetNamespace="http://127.0.1.1:8000/SMSService/getPrice"> <xsd:complexType name="paramsTypes"> <xsd:sequence> <xsd:element name="a" type="xsd:integer"/> </xsd:sequence> </xsd:complexType> <xsd:element name="params" type="tns:paramsTypes"/> <xsd:element name="returns" type="xsd:integer"/> </xsd:schema> </wsdl:types> <wsdl:message name="SMSServiceRequest"> <wsdl:part element="tns:params" name="parameters"/> </wsdl:message> <wsdl:message name="SMSServiceResponse"> <wsdl:part element="tns:returns" name="parameters"/> </wsdl:message> <wsdl:portType name="SMSServicePortType"> <wsdl:operation name="getPrice"> <wsdl:input message="tns:SMSServiceRequest"/> <wsdl:output message="tns:SMSServiceResponse"/> </wsdl:operation> </wsdl:portType> <wsdl:binding name="SMSServiceBinding" type="tns:SMSServicePortType"> <soap:binding style="document" transport=" http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="getPrice"> <soap:operation soapAction="http://127.0.1.1:8000/SMSService" style="document"/> <wsdl:input> <soap:body use="literal"/> </wsdl:input> <wsdl:output> <soap:body use="literal"/> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="SMSService"> <wsdl:port binding="tns:SMSServiceBinding" name="SMSServicePort"> <soap:address location="http://127.0.1.1:8000/SMSService"/> </wsdl:port> </wsdl:service> </wsdl:definitions> # client: package client; import javax.xml.namespace.QName; import org.apache.axis2.addressing.EndpointReference; import org.apache.axis2.client.Options; import org.apache.axis2.rpc.client.RPCServiceClient; public class client_for_python { public static void main(String[] args) throws Exception { // step 1: 使用RPC方式调用WebService RPCServiceClient serviceClient = new RPCServiceClient(); Options options = serviceClient.getOptions(); // step 2: 指定调用WebService的URL // url for python String url2 = "http://172.16.2.46:8000/SMSService"; EndpointReference targetEPR = new EndpointReference(url2); options.setTo(targetEPR); // step 3: 指定getGreeting方法的参数值 // step 5-6: (similiar whit // it!)下面是调用getPrice方法的代码，这些代码与调用getGreeting方法的代码类似 Class[] classes = new Class[] { int.class }; QName opAddEntry = new QName( "http://172.16.2.46:8000/SMSService/getPrice"); System.out.println(serviceClient.invokeBlocking(opAddEntry, new Object[] {1}, classes)[0]); } } # NOTE: the client get nothing from sever-side and server-side get nothing from Axis2-client.

Suds error
by Remy de Boer 06 Dec '11

06 Dec '11

Hi, I'm trying to connect to the SOAP interface of an innovaphone system. I'm using the following code to connect to the WSDL file: from suds.client import Client > from suds.xsd.doctor import ImportDoctor, Import > from suds.transport.http import HttpAuthenticated > > imp = Import('http://schemas.xmlsoap.org/soap/encoding/') > imp.filter.add('http://innovaphone.com/pbx') > imp.filter.add('http://innovaphone.com/binding') > > d = ImportDoctor(imp) > url = 'http://localhost/pbx800.wsdl' > t = HttpAuthenticated(username='****', password='****') > > client = Client(url, transport=t, doctor=d) > > print client > print client.service.Version() > The WSDL file I'm using is the same as at: http://www.innovaphone.com/wsdl/pbx800.wsdl With the 5th to last line (soap:address location) edited to point to our PBX server. running the above script results in the following error: File "sudstest.py", line 16, in <module> > print client.service.Version() > File > "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/client.py", line > 542, in __call__ > return client.invoke(args, kwargs) > File > "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/client.py", line > 602, in invoke > result = self.send(soapenv) > File > "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/client.py", line > 643, in send > result = self.succeeded(binding, reply.message) > File > "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/client.py", line > 678, in succeeded > reply, result = binding.get_reply(self.method, reply) > File > "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/bindings/binding.py", > line 149, in get_reply > soapenv.promotePrefixes() > AttributeError: 'NoneType' object has no attribute 'promotePrefixes' > When I quote out the "print client.service.Version()" line, it displays all the methods from the WSDL file, but when I leave it uncommented, the "print client" line doesn't get printed before the error comes up. Any idea what's causing this error? I'm using python version 2.6.6 and suds version 0.4 Thanks in advance! -Remy

python webservice SUDS soapheader
by 贾晓磊 02 Dec '11

02 Dec '11

HI, all: Recently I am doing something about python webservice. With the help of some groups, most of problems has been solved. Now, how to pass SOAP heasers makes me confused. I try to get help from web, such as http://stackoverflow.com/questions/2469988/how-to-pass-soap-headers-into-py… , http://stackoverflow.com/questions/2964867/add-header-section-to-soap-reque…, they indeed provide some valuable advises, but the problem still exists. I will describe it in detail as follows: part 1: I need to construct this soapheaders using SUDS. <soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <ReqSOAPHeader soapenv:actor="http://schemas.xmlsoap.org/soap/actor/next" soapenv:mustUnderstand="0" xmlns="http://common.v1_0.obj.protocol.xxt"> <serviceCode>PABB4BEIJING</serviceCode> <servicePwd>QWERTPABB</servicePwd> </ReqSOAPHeader> </soapenv:Header> part 2: my code import suds def test_sms9(): #step 1: import a encode from suds.xsd.doctor import ImportDoctor, Import imp = Import('http://schemas.xmlsoap.org/soap/encoding/') d = ImportDoctor(imp) #step 2: set the logging import logging logging.basicConfig(level=logging.ERROR) # step 3: construt client url = " http://211.137.45.104:9006/LnXxtCpInterface/services/LNXxtSyncService?wsdl" client = suds.client.Client(url,doctor=d,cache=None,xstq=False,faults=False) # step 4: create the header from suds.sax.element import Element from suds.sax.attribute import Attribute code = Element('serviceCode').setText('PABB4BEIJING') pwd = Element('servicePwd').setText('QWERTPABB') header_list = [code, pwd] client.set_options(soapheaders=header_list) #

NOTE: the body is omitted. SOAP Response: # it's same with mentioned above. I try to change the code to "reqsoapheader = Element('ReqSOAPHeader').insert([code,pwd]) ". it failed. Last, how to generate a soapheader as : <SOAP-ENV:Header> <ReqSOAPHeader> <serviceCode>xxxx</serviceCode> <servicePwd>yyy</servicePwd> </ReqSOAPHeader> <SOAP-ENV:Header> Any advice will be highly appreciated. Thanks and regards ahead for the the time and concentration. Thanks again! -- Jia Xiaolei
