How to send an user name from Flex to the PHP file and receive its email address
(naturally you could make a query to the db to get these values)
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute"
creationComplete="init(event)" >
<mx:Script>
<![CDATA[
import mx.events.FlexEvent;
private const NOME_UTENTE:String = "Fabio Biondi";
private function init(evt:FlexEvent):void
{
phpRPC.url="assets/Es02_CheckUser.php";
phpRPC.send({ utente: NOME_UTENTE} )
}
private function viewEmail():void
{
outputArea_txt.text = phpRPC.lastResult.email
}
]]>
</mx:Script>
<mx:HTTPService
id="phpRPC"
resultFormat="flashvars"
result="viewEmail()"
/>
<mx:TextArea
id="outputArea_txt" y="20"/>
</mx:Application>
// PHP CODE
<?php
switch($_REQUEST['utente'])
{
case "Fabio Biondi":
echo "email=info@fabiobiondi.com";
break;
default:
echo "email=User not found";
break;
}
?>
suppose your HTTPService goes to a server that need basic authentication, you'll be prompted EACH time with a pop-up, fill with user and password. This can be very annoying specially in long dev/debug session.
setCredentials and setRemoteCredentials for different reasons, don't work with "simple" http auth.
Solution:
- add custom header and send it before any further request
how to implement:
- define your HTTPService as you desidred (mxml, as)
- add initialization code as shown below:
<?xml version="1.0"?>

Reading RSS feeds from Flex or Flash often generate some security issues when the origin domain doesn't contain a crossdomain.xml file to manage the policy settings.
A little workaround is create a PHP proxy to read the feeds and pass the content to the Flex script.
In few words, instead to call the original xml feed
<mx:HTTPService id="loadXML"
url="
http://www.hwupgrade.it/rss_hwup.xml "
...
you'll call the php script passing the url property
<mx:HTTPService id="loadXML"
url="
http://localhost/path/rssReader.php?url=http://www.hwupgrade..."
...
<?php
readfile($_REQUEST["url"]);
?>
