SOAP Headers with Consumed Web Services

  • Article

After you add Web services to your orchestration using the Add Web Reference dialog box, you can use the SOAP headers that the Web Services Description Language (WSDL) defines in the Web service.

Note

Consumed Web services do not support unknown SOAP headers.

The WSDL for the consumed Web service lists the defined SOAP headers in the binding element. The following example shows a binding element in the WSDL file for the consumed Web service:

<?xml version="1.0" encoding="utf-8"?>
<definitions xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:s0="http://SOAPHeaderWS.ItemAvailability" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" targetNamespace="http://SOAPHeaderWS.ItemAvailability" xmlns="http://schemas.xmlsoap.org/wsdl/">
       <types>
             <s:schema elementFormDefault="qualified" targetNamespace="http://SOAPHeaderWS.ItemAvailability">

                    <s:element name="OrigDest" type="s0:OrigDest"/>
                    <s:complexType name="OrigDest">
                           <s:sequence>
                                 <s:element minOccurs="0" maxOccurs="1" name="Origination" type="s:string"/>
                                 <s:element minOccurs="0" maxOccurs="1" name="Destination" type="s:string"/>
                           </s:sequence>
                    </s:complexType>
             </s:schema>
       </types>

       <binding name="ItemAvailabilityServiceSoap" type="s0:ItemAvailabilityServiceSoap">
             <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
             <operation name="ItemAvailability">
                    <soap:operation soapAction="http://SOAPHeaderWS.ItemAvailability/ItemAvailability" style="document"/>
                    <input>
                           <soap:body use="literal"/>
                           <soap:header message="s0:ItemAvailabilityOrigDest" part="OrigDest" use="literal"/>
                    </input>
                    <output>
                           <soap:body use="literal"/>
                           <soap:header message="s0:ItemAvailabilityOrigDest" part="OrigDest" use="literal"/>
                    </output>
             </operation>
       </binding>
       <service name="ItemAvailabilityService">
             <port name="ItemAvailabilityServiceSoap" binding="s0:ItemAvailabilityServiceSoap">
                    <soap:address location="http://localhost/SOAPHeaderWS/ItemAvailability.asmx"/>
             </port>
       </service>
</definitions>
