Consuming A WebService With Flash Media Server 2
 By Stefan Richter
Here's a very simple example on how to invoke and consume a WSDL webservice using serverside Actionscript.
You will need Flash Media Server 2 for this, it will not work in Flash Communication Server.
The Webservice I am consuming in this example simply returns the currency exchange rate between two countries. For each country we must pass a string identifying the country, in this case I use 'UK' and 'USA'.
What follows is pure ASC (serverside Actionscript). No .fla file or clientside code is needed to run this.
Here is the content of my main.asc file (you can just copy and paste this code and save it as 'main.asc'):
In order to run this code you need to create a new application inside your FMS2's applications directory. I called my folder 'wsdl'. Next you should open the Flash Media Server admin console and load the 'wsdl' application. Then hit reload application. You should see the following traces:
Note that the traces such as
are generated by the 'imported' Actionscript files on line 1. They aren't traces produced by my code. Anyone know why param:Result traces undefined?
The documentation on webservices with FMS2 leaves a bit to be desired. My example was based on the code samples of in the live docs.
