HTTP communications
XML-RPC web service requests
Flash Player 9 and later, Adobe AIR 1.0 and later
An XML-RPC web service takes its call parameters as an XML document rather than as a set of URL variables. To
conduct a transaction with an XML-RPC web service, create a properly formatted XML message and send it to the web
service using the HTTP POST method. In addition, you should set the Content-Type header for the request so that the
server treats the request data as XML.
The following example illustrates how to use the same web service call shown in the REST example, but this time as an
XML-RPC service:
import flash.events.Event;
import flash.events.ErrorEvent;
import flash.events.IOErrorEvent;
import flash.events.SecurityErrorEvent;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLRequestMethod;
import flash.net.URLVariables;
public function xmlRPCRequest():void
{
//Create the XML-RPC document
var xmlRPC:XML =
;
xmlRPC.methodName = "test.echo";
//Add the method parameters
var parameters:Object = new Object();
parameters.api_key = "123456ABC";
parameters.message = "Able was I, ere I saw Elba.";
for( var propertyName:String in parameters )
{
xmlRPC..struct.member[xmlRPC..struct.member.length + 1] =
{propertyName}
{parameters[propertyName]}
;
}
//Create the HTTP request object
var request:URLRequest = new URLRequest( "http://service.example.com/xml-rpc/" );
request.method = URLRequestMethod.POST;
request.cacheResponse = false;
request.requestHeaders.push(new URLRequestHeader("Content-Type", "application/xml"));
