What are soap bindings and how are soap messages exchanged?


Asked by Emilio Rollins on Dec 11, 2021 FAQ



The SOAP specification defines the structure of the SOAP messages, not how they are exchanged. This gap is filled by what is called "SOAP Bindings". SOAP bindings are mechanisms which allow SOAP messages to be effectively exchanged using a transport protocol.
Consequently,
A SOAP binding can also have an encoded use or a literal use. This gives us Five style/use models which we call as Message Exchange Format (MEF) or SOAP message binding style MEF: The format of the information which is exchanged between service provider and the consumer is called MEF.
Also Know, The SOAP extension elements include the following − This element indicates that the binding will be made available via SOAP. The style attribute indicates the overall style of the SOAP message format. A style value of rpc specifies an RPC format. The transport attribute indicates the transport of the SOAP messages.
Additionally,
SOAP defines a binding to the HTTP protocol. This binding describes the relationship between parts of the SOAP request message and various HTTP headers. All SOAP requests use the HTTP POST method and specify at least three HTTP headers: Content-Type, Content-Length, and a custom header SOAPAction.
Moreover,
As the cornerstone of Web services technology which is commonly used to implement SAP's Enterprise SOA, SOAP is an internet-based lightweight protocol for exchanging XML messages in a distributed environment.
