SOAP (originally Simple Object Access Protocol) is a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks Its purpose is to induce extensibility , neutrality and independence. Note that the WSDL for the SOAP v2 API is different when in WS-I compliant mode. You may have an n-tier architecture where some of your business logic is coded outside the database and the services you intend to write need access to that business logic. It defines a set of rules for structuring messages that can be used for simple one-way messaging but is particularly useful for performing RPC-style (Remote Procedure Call) request-response dialogues.
Instead they can expose and access web services using technology already deployed. Juste a note to avoid wasting time on php-soap protocol and format support. NormalizeNames: if your wsdl operations contains names with non identifier characters (^a-z$_0-9), replace them with _. Note: if using this option, clients using wsdls with two operations like soap:method and soap-method will be overwritten.
Wsdl_headers: custom HTTP headers to be sent on WSDL requests. Soap is recovered from Diversey hotel customers which are Soap for HopeTM program partners, and then transported to a local site where residents reprocess it using an innovative but simple cold-press method.
Yes there is probably a huge database behind the webservice, but it doesn’t remember the state of the client. Soap.listen(server, path, services, wsdl) – create a new SOAP server that listens on path and provides services. A Fault element can only appear once in a SOAP message.
The Web Services Description Language ( WSDL ) describes a common set of rules to define the messages, bindings, operations and location of the service. On the server side you will notice that the SOAP package relies on some XML Parser to parse the SOAP messages.
