I have a WCF web service that connects to most applications using wsHttpBinding. I have to connect to this web service from a classic asp file. From what I have read and tried, I need to use basicHttpBinding to do this. It is SOAP 1.1 and to use webhttpbinding, I would have to change the web service interface by adding [WebGet]
and this is not an option. So I added the basicHttpBinding to the web service.
I run the asp file using a console application. When it is run, I get the error:
The message with Action 'urn:http://tempuri.org/IPaging/TestMethod' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).
I don't see where I am going wrong. I have the URL set to call the basic binding. The SOAP message is using 1.1 and I believe it is correct.
Why is there a mismatch between the sender and receiver?
There is no app.config file on the client side to define the connection. It is just 1 asp file. If I need that, how does the asp file read the app.config file?
Config file below:
<system.serviceModel>
<services>
<service name="PagingService.Paging" behaviorConfiguration="SimpleServiceBehavior">
<endpoint address="" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IPaging" contract="PagingService.IPaging">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="basic" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IPaging" contract="PagingService.IPaging">
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<host>
<baseAddresses>
<add baseAddress="http://localhost:8732/Design_Time_Addresses/PagingService/Service1/"/>
</baseAddresses>
</host>
</service>
</services>
<bindings>
<wsHttpBinding>

</binding>
</wsHttpBinding>
<basicHttpBinding>

</binding>
</basicHttpBinding>
</bindings>

</behavior>

</behaviors>
</system.serviceModel>
I want to call the method TestMethod
from the paging service from the classic asp file
This is the WSDL that describes the TestMethod:
<wsdl:operation name="TestMethod">
<wsdl:input wsaw:Action="http://tempuri.org/IPaging/TestMethod" message="tns:IPaging_TestMethod_InputMessage" />
<wsdl:output wsaw:Action="http://tempuri.org/IPaging/TestMethodResponse" message="tns:IPaging_TestMethod_OutputMessage" />
</wsdl:operation>
<wsdl:operation name="TestMethod">
<soap:operation soapAction="http://tempuri.org/IPaging/TestMethod" style="document" />
- <wsdl:input>
<soap:body use="literal" />
</wsdl:input>
- <wsdl:output>
<soap:body use="literal" />
</wsdl:output>
</wsdl:operation>
This is how the basicHttpBinding is defined in the WSDL:
<wsdl:port name="BasicHttpBinding_IPaging" binding="tns:BasicHttpBinding_IPaging">
<soap:address location="http://<server>:<port>/Fld1/PagingService.Paging.svc/basic" />
</wsdl:port>
This is the asp code that calls the web service:
Dim NS, NS_SOAP, NS_SOAPENC, NS_XSI, NS_XSD
NS = "urn:http://tempuri.org/"
NS_SOAP = "http://schemas.xmlsoap.org/soap/envelope/"
NS_SOAPENC = "http://schemas.xmlsoap.org/soap/encoding"
NS_XSI = "http://www.w3.org/2001/XMLSchema-instance"
NS_XSD = "http://www.w3.org/2001/XMLSchema"
'Using basicHttpBinding
URL = "http://<server><port>/Fld1/PagingService.Paging.svc/basic"
' XML DOM objects.
Dim DOM, Envelope, Body, Operation, Param
' Creates an XML DOM object.
Set objXmlDoc = CreateObject("MSXML2.DOMDocument.6.0")
objXmlDoc.async = false
Set Envelope = objXmlDoc.createNode(1, "soap:Envelope", NS_SOAP)
Envelope.setAttribute "xmlns:soapenc", NS_SOAPENC
Envelope.setAttribute "xmlns:xsi", NS_XSI
Envelope.setAttribute "xmlns:xsd", NS_XSD
objXmlDoc.appendChild Envelope
Set Body = objXmlDoc.createNode(1, "Body", "http://schemas.xmlsoap.org/soap/envelope/")
Envelope.appendChild Body
Set Operation = objXmlDoc.createNode(1, "TestMethod", NS)
Body.appendChild Operation
Set httpRequest = Server.CreateObject("MSXML2.ServerXMLHTTP.6.0")
httpRequest.Open "POST", URL, False
httpRequest.setRequestHeader "Content-Type", "text/xml"
httpRequest.setRequestHeader "SOAPAction", "urn:http://tempuri.org/IPaging/TestMethod"
httpRequest.send objXmlDoc.xml
strStatusText = "Status: " & httpRequest.status & vbCrLf & "Status text: " & httpRequest.statusText
Response.Write(vbCrLf & strStatusText & vbCrLf)
Response.Write(httpRequest.responseText)
Set Operation = Nothing
Set Body = Nothing
Set Envelope = Nothing
Figured this out.
Removed urn:
from NS constant and SOAPAction strings and it worked.
