This is so cool: Jed Hurt has released Alpha 0.1 of SWX Ruby, the Ruby implementation of SWX RPC for Ruby on Rails.

Why am I getting Security Sandbox Violations in the Flash IDE when running the sample applications or my own applications?

Summary: This warning only occurs when testing your applications from the Flash IDE. Cross-domain data exchange will work correctly when you run your applications from a web server. You can ignore this warning.

SWX RPC lets you to make cross-domain data calls (you can turn this off by setting the allowDomain option in the SWX PHP configuration file at php/swx_config.php to false). This means, for example. that you can have a SWF running on your development server or on your shared host somewhere and you can still consume the SWX RPC services (APIs) on the Public SWX Gateway on swxformat.org.

The Flash IDE, however, will display a Security Sandbox Violation when you run SWX applications in the IDE. This is because applications that run in the IDE use the file:// protocol as opposed to http://. Rest assured that your applications will work correctly when tested from a web server using the http:// protocol.

In short, you can safely ignore this warning.

For a longer explanation, read on.

The way SWX RPC enables cross-domain data exchange is by writing an allowDomain statement to the exact URL of the SWF that called it (your application) in the SWX data SWF that it sends back. The SWX ActionScript Library sends this URL in the SWX RPC call for you.

If you are using the native method via loadMovie(), you need to send the value of _url in a parameter called url in your SWX RPC call manually. Alternatively, when using the native method, if you don't send a url parameter, you can specifically allowDomain the loaded SWX data SWF from the main application and it, in turn, it will allowDomain its parent (your application) if it doesn't receive the url. This second method is discouraged, however, as the SWX data SWF should not require access to your application (if only does so to allow your application access to itself by calling allowDomain on _parent) and a fake SWX data SWF from an untrusted SWX RPC gateway could possibly access data and/or alter your main application when using this method.

To summarize, you can ignore this warning and you should either send a url parameter when using the native method via loadMovie() in SWX RPC or, even simpler, use the SWX ActionScript Library when your applications need to access data across domains.

SWX ActionScript Library: using the prepare() method of the SWX class

When working with SWX RPC, you don't want to continuously serialize complex arguments by hand when call server-side methods. And you don't have to, if you use the prepare() method of the SWX class in the SWX ActionScript Library that comes with SWX PHP.

Save your FLA in the flash/ folder (the one that has the org and com folders) before continuing. (Or add that folder to your ActionScript classpath in the Flash IDE and save your FLA anywhere.)

Modify the code sample so that it matches the listing below:

import org.swxformat.SWX;
 
dataHolder.serviceClass = "Calculator";
dataHolder.method = "addNumbers";
dataHolder.args = [35, 7];
dataHolder.debug = true;
 
SWX.prepare(dataHolder);
 
dataHolder.loadMovie("http://localhost:8888/php/swx.php", "GET");
 
function onEnterFrame()
{
    status.text = dataHolder.result;
}

The prepare() static method of the SWX class simply serializes your arguments into JSON format for you. Notice that the args property in your dataHolder is no longer a string but an ActionScript array with two numbers inside it.

This is definitely far better than manually serializing your arguments by hand but it's still not ideal, is it? For one thing, that onEnterFrame function we're using is not a good practice. It would be really nice if we could have an event handler called when the data arrives instead of polling for it. The SWX ActionScript Library provides that functionality for you too.

Before testing the movie, open the SWX Data Analyzer in a separate browser window.

SWX Data Analyzer is a debugging tool that shows you the SWX data that arrives inside your Flash movie.

To make SWX data that loads into the Flash player appear in Analyzer, you turn debug mode on. That's what the line dataHolder.debug = true does.

Now, test your movie and then look in the Analyzer. If all went well, you should see the number 42.

Calling SWX PHP methods from Flash

You've verified that your server-side service method is working correctly by using the SWX Service Explorer. Now let’s call this method from Flash.

Open up Flash and create a new FLA (ActionScript 2). You can set the publish setting to Flash 7 or 8.
On Frame 1 of the new FLA, create a movie clip instance and give it the instance name dataHolder.
Create a new layer and call it Actions. On the Actions layer, add the following code:

dataHolder.serviceClass = "Calculator";
dataHolder.method = "addNumbers";
dataHolder.args = "[35, 7]";
dataHolder.debug = true;
 
dataHolder.loadMovie("http://localhost:8888/php/swx.php", "GET");

That's it! That's all the code you need to call the addNumbers method on the Calculator service class in PHP and pass it the numbers 35 and 7 as arguments. The loadMovie calls the SWX gateway and passes to it any of the properties you set on your movie clip. In this case, since we are sending a small number of arguments, we use the GET HTTP encoding method. We could just as easily have used POST.

In Flickr Word by Eugene, you type some text and see it displayed using Flickr photos, either as a font, or (as in the screenshot above) with pictures of letters. Right-click to access the various options. In full-screen mode, I was able to use the scroll-wheel (two-finger dragging on my MacBook Pro's trackpad) to quickly change the zoom factor.
