WCF Receive Adapter

  • Artigo

The WCF receive adapter enables you to receive WCF service requests.

Extracting the BizTalk Message Body from the SOAP Message

The inbound BizTalk message body can be extracted from the SOAP message by using one of the following options:

  • Extract the content of the SOAP Body element

  • Extract the entire SOAP envelope

  • Extract the content of the element inside the SOAP envelope by using an XPath expression

    You can configure these options in the transport properties dialog box.

Extract the Content of the SOAP Body Element

When this option is selected, the inner content of the SOAP Body element is read from the SOAP message and placed into the body part of the BizTalk message.

Extract the Entire SOAP Envelope

When this option is selected, the entire SOAP envelope including the tag is placed into the body part of the BizTalk message.

Extract the Content of the Element by Using an XPath Expression

When this option is selected, the inner content of the element inside the SOAP Body element that is located by the XPath expression is placed into the body part of the BizTalk message. The rest of the data in the Body element is ignored. You also need to specify the node encoding—for example, XML, Base64, Hex, or String encoding.

Note

When the XML encoding is selected, the outer content of the element is located by the XPath expression and placed into the body part.

Handling Web Services Headers

The receive adapter promotes a subset of the standard Web services headers onto the BizTalk message context to enable easy access and routing based on values of those headers. The following table lists the properties that will be saved onto the message context by the receive adapter. The properties are defined under the following namespaces: http://www.w3.org/2005/addressing and http://schemas.microsoft.com/BizTalk/2006/Adapters/WCF-properties.
