Zend AMF Yii module

The module amfGateway permits anyone to have a very easily configurable RPC with Flash and Flex.

Features

This Yii module uses Zend AMF to communicate with Flashor Flex applications.

Setting up and usage

To use the module follow these steps:

1. Make sure you have a modules folder in your protected folder of your Yii application. If not create it.
2. Inside the modules directory copy the modules/amfGateway folder provided by this repository.
3. Now you have to enable the module in your Yii application. Open the file protected/config/main.php and in the modules section add

'modules' => array(
  'amfGateway' => array(
    'servicesDirAlias' => 'application.services.amf',
    'production' => TRUE,
   )
),

Now your gateway for AMF is found at http://yiiurl?r=amfGateway. The classes and methods that are exposed to Flash/Flex are found in the application.services.amf directory which essentially is protected/services/amf. You can find an example in the services/amf/TestService.php file that is provided.

If you have any problem while setting it up and you want to see more error messages, change the 'production' parameter seen above to FALSE.

Zend AMF is located in the vendors/ folder inside the module folder. If it is not up-to-date can be easily updated by downloading Zend AMF from http://framework.zend.com/download/amf and then extracting the Zend folder directly into the Zend folder.

##Using the module while still having the CSRF protection enabled for the rest of the application

The module will not work if you have CSRF protection enabled for the application. One of the ways to make it work, is to disable the CSRF protection only for the module. To this end the user backloop from the Yii framework forum suggested a solution. To summarize it:

1. Extend CHttpRequest (created /components/FlkHttpRequest.php):

class FlkHttpRequest extends CHttpRequest
{
        public $noCsrfValidationRoutes=array();

        protected function normalizeRequest()
        {
                parent::normalizeRequest();
                
                if($this->enableCsrfValidation)
                {
                        $currentRoute=Yii::app()->getUrlManager()->parseUrl($this);
                        foreach($this->noCsrfValidationRoutes as $route)
                        {
                                if(strpos($currentRoute,$route)===0)
                                        Yii::app()->detachEventHandler('onBeginRequest',array($this,'validateCsrfToken'));
                        }
                }
        }       
}

2. Configure it in /config/main.php:

'components'=>array(
        ...
        ...,
        'request'=>array(
                'class'=>'FlkHttpRequest',
                'enableCsrfValidation'=>true,
                'noCsrfValidationRoutes'=>array('amfGateway'),
        ),
),

Demo

You can view a demo live at: TODO

There is a flash example in the folder flash_demo. To make it work make sure you setup the module as described above. Then copy the services folder in the yii protected/ folder. After that go to amftest.as and change the following line

 var gateway:String = "http://amftestapp/index.php?r=amfGateway";

to make sure it points to the right URL according to your computer. You can now run amftest.fla and see in the console the results.
