the detail of HttpService

<mx:HTTPService id="registerService" showBusyCursor="true" useProxy="false" url="register.action" resultFormat="e4x" method="POST" result="registerConfirmation(event)" fault="registerFailed(event)"/>

 

 

register.action is the Struts 2 action that registers the user

registerConfirmation(event) is the function that is called if the http service call is successful.

registerFailed(event) is the function that is called if an error occurs. For example if the server is down. The event object gives you access to any xml/html that might be returned upon the call of the action.

resultFormat specifies in which format you want to view the results. It can be text, xml or an object. There are 5 possible values for this field:

• object - An XML object is returned and is parsed as a tree of ActionScript objects
  
• xml - Returns literal XML in an XMLNode object
  
• e4x - Returns literal XML that can be accessed using ECMAScript for XML(E4X) expressions.
  
• flashvars - The result is text in flashvars format, value pairs separated by ampersands. Flex returns this result in an actionscript object
  
• array - The result is XML that is returned in an Array even if there is only one top level node.
