PowerBuilder provides support for custom SOAP headers in .NET Web services. The PowerBuilder .NET Web Service proxy generator creates a structure for methods of the Web service that require authentication information transmitted in the SOAP header. The number of fields in the generated structure, and their datatypes, depend on information contained in the Web service's SOAP header class.
The name of the generated structure consists of the prefix, if any, that you assign to the Web service proxy, and the name of the SOAP header class for the Web service. For example, if you assign “ws_” as the proxy prefix and the SOAP header class name is “Authentication”, then the generated structure name will be “ws_Authentication”.
The proxy generator also creates at least one function for passing authentication values in or to the generated structure. The type of function or functions created is determined by the direction parameter in the Web service SOAP header class. The direction can be “in”, “out”, or “inout”.
If the direction is “in”, the PowerBuilder .NET Web Service proxy generator creates a function you can use to pass the generated structure to the Web service after populating the structure with authentication values. The name of this function consists of the name of the Web Service SOAP header class with a “set” prefix and a “value” suffix.
For the example with the SOAP header class named “Authentication”, the syntax for the function is:
boolean setAuthenticationValue (ws_Authentication AuthenticationValue)
The return value is true for success, and false for failure. In this example, AuthenticationValue is a variable for the generated structure that you submit to the Web service in a custom header. If the value of the SOAP header direction parameter is “out”, the PowerBuilder .NET Web Service proxy generator creates a function you can use to get information back from the SOAP header in a Web service call. The name for this function consists of the name of the SOAP header class with a “get” prefix and a “value” suffix.
For the example with the SOAP header class named “Authentication”, the syntax for this function is:
ws_Authentication getAuthenticationValue ( )
For the same example when the SOAP header direction parameter is “inout”, both the setAuthenticationValue and getAuthenticationValue functions are created. You can call these functions in PowerScript to set and return authentication values in a custom SOAP header.
