WCF Adapter对SOAPHeader的处理

前面的博客提到过SOAP Adapter与WSE Adapter对SOAPHeader的处理。最近使用WCF Adapter，感觉处理方法略有不同。

首先，与SoapHeader有关的Message Type.



定义一个Property Schema,添加一个属性节点，属性节点的名称必须与wsdl导出的SoapHeader部分的节点名称完全一致。而且，设置Property Schema的"Target NameSpace"属性值为“http://schemas.microsoft.com/BizTalk/2003/SOAPHeader”
。设置节点的"Property Schema Base"属性值为“MessageContextPropertyBase"


在Orchestration中，
InboundSOAPHeaderXML = WSActivateMsg(CustomSOAPHeaderClass);
CustomSOAPHeaderClass是Property Schema中的属性名，InboundSOAPHeaderXML是string类型的变量。


添加CustomSOAPHeaderCls xsd类型的消息。通过如下方法，
public XmlDocument PrepareSOAPHeaderClass(string sSOAPHeaderXML)
        {
            XmlDocument soapHeaderOut = null;
            if (sSOAPHeaderXML != "")
            {
                XmlDocument soapHeaderIn = new XmlDocument();
                try
                {
                    soapHeaderIn.LoadXml(sSOAPHeaderXML);

                    string sXML = soapHeaderIn.DocumentElement.OuterXml;
                    soapHeaderOut = new XmlDocument();
                    soapHeaderOut.LoadXml(sXML);
                }
                catch(Exception ex)
                {
                    soapHeaderOut = null;
                }
            }
            return soapHeaderOut;
        }

返回的XmlDocument变量来构造CustomSOAPHeaderCls消息。


通过map由CustomSOAPHeaderCls消息构造Multi-part Message。


把SoapHeader信息attach到SoapIn中：
CommonCallRequest(WCF.OutboundCustomHeaders)="<headers>"+IntegrationUtil.ExtractXMLString(OutboundSOAPHeader)+"</headers>";
其中，OutboundSOAPHeader是Multi-part Message.
 public string ExtractXMLString(XmlDocument xmlDoc )
        {
            string sXML = "";
            if (xmlDoc != null)
            {
                sXML = xmlDoc.DocumentElement.OuterXml;
            }
            return sXML;
        }
