WebService class 163
3. (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;
}
4.
(Optional) Handle the fault if the WSDL doesn’t load:
// If the WSDL fails to load the onFault event is fired.
stockService.onFault = function(fault){
wsdlField.text = fault.faultstring;
}
5.
(Optional) Set the SOAP headers:
// If headers are required they are added as follows:
var myHeader = new XML(headerSource);
stockService.addHeader(myHeader);
6.
Invoke a web service operation:
// Method invocations return an asynchronous callback.
callback = stockService.doCompanyInfo("anyuser", "anypassword", "MACR");
// NOTE: callback is undefined if the service itself is not created
// (and service.onFault is also invoked).
7.
Handle either the output or the error fault returned from the invocation:
// Handle a successful result.
callback.onResult = function(result){
// Receive the SOAP output, which in this case
// is deserialized as a struct (ActionScript object).
stock.companyInfo = result;
}
// Handle an error result.
callback.onFault = function(fault){
// Catch the SOAP fault and handle it
// according to this app's requirements.
stock.companyInfo = fault.faultstring;
}
