42 Chapter 2: Using Flash Remoting ActionScript
In this example, the service function passes two parameters, a language specification (en_US), and
a type of category (
"Accessories").
Note: Parameters must be in the order required by the service function.
import mx.remoting.Service;
import mx.remoting.PendingCall;
import mx.rpc.RelayResponder;
import mx.rpc.ResultEvent;
import mx.rpc.FaultEvent
// create RelayResponder to specify result handling methods
var myResponder:RelayResponder = new
RelayResponder(this,"getCategories_Result","getCategories_Fault");
// establish gateway and create a Service object to refer to the service
var petMarketService:Service = new Service(
"http://examples.macromedia.com/flashservices/gateway",
null,
"petmarket.api.catalogservice",
null,
myResponder );
// set user credentials
petMarketService.connection.setCredentials("myUserName","myPassword");
// call service function
var temp_pc:PendingCall = petMarketService.getCategories("en_US");
// getCatergories_Result and getCategories_Fault are result/fault handlers
function getCategories_Result (re:ResultEvent):Void {
trace("Got Categories - " + re.result.length + " Record" + (re.result.
length>1?"s":""));
}
function getCategories_Fault (fe:FaultEvent):Void {
trace("CategoriesCallFailed-" + fe.fault.description);
}
