Chapter 2: Using Flash Remoting ActionScript
For example, to create a service object for the Macromedia Pet Market catalog web service, specify
a line similar to the following:
petMarketCatalogService = gatewayConnection.getService("petmarket.api.
catalogservice”, this);
Authenticating a user to the application server
In some cases, your application server might require you to provide user authentication—a user
name and password—before you can use a service.
Flash Remoting provides the
setCredentials()
method of the Connection object to allow you
to specify authentication credentials to send to the application server. Flash Remoting sends the
credentials in the header of every service function call. This method is currently supported on the
following servers:
•
ColdFusion MX
•
JRun 4
To use the
setCredentials()
method, call the method after you have created the gateway
connection and before you call a service function. For a Flash application that is run by a single
user during a session, you can call the
setCredentials()
method any time after creating the
gateway connection object. If you created the gateway object using the Service object, you can
access the connection object through the
connection
property and call
setCredentials()
to
provide authentication, as shown in the following example:
import mx.remoting.Service;
import mx.remoting.PendingCall;
import mx.rpc.RelayResponder;
import mx.rpc.ResultEvent;
import mx.rpc.FaultEvent
function getCategories_Result (re:ResultEvent):Void {
trace("Got Categories - " + re.result. " Record" + (re.result.
length>1?"s":""));
}
function getCategories_Fault (fault:FaultEvent):Void {
trace("CategoriesCallFailed-" + fault.fault.description);
}
var myResponder:RelayResponder = new
RelayResponder(this,"getCategories_Result","getCategories_Fault");
var petMarketService:Service = new Service(//establish connection
"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");
Note:
To ensure security, never include specific user names or passwords in ActionScript.
