WebService class

Availability

Flash Media Server 2

Description

You can use the WebService class to create and access a WSDL/SOAP web service. Several classes comprise the Flash

Media Interactive Server web services feature: WebService class, SOAPFault class, SOAPCall class, and Log class.

Note: The WebService class is not able to retrieve complex data or an array returned by a web service. Also, the

WebService class does not support security features.

The following steps outline the process of creating and accessing a web service.

Create and access a web service:

Load the WebServices class:

load("webservices/WebServices.asc");

2 Prepare the WSDL location:

var wsdlURI = "http://www.flash-db.com/services/ws/companyInfo.wsdl";

3 Instantiate the web service object by using the WSDL location:

stockService = new WebService(wsdlURI);

4 (Optional) Handle the WSDL parsing and web service instantiation event through the WebService.onLoad()

handler:

// Handle the WSDL loading event.

stockService.onLoad = function(wsdl){

wsdlField.text = wsdl;

}

5 (Optional) If the WSDL doesn’t load, handle the fault:

// If the WSDL fails to load, the onFault event is fired.

stockService.onFault = function(fault){

wsdlField.text = fault.faultstring;

}

6 (Optional) Set the SOAP headers:

// If headers are required, they are added as follows:

var myHeader = new XML(headerSource);

stockService.addHeader(myHeader);

7 Invoke a web service operation:

// Method invocations return an asynchronous callback.

callback = stockService.doCompanyInfo("anyuser", "anypassword", "ADBE");

// NOTE: callback is undefined if the service itself is not created
