cakePHP中的RESTful Web服务

Question

I followed the tutorial on this website which explains how to setup REST with cakePHP, but after I did all this, when I call my controller in the browser (for example I have a PostsController which has the default CRUD actions), I still get html as my response (not xml). It seems like the view file that's being called is the one in app/views/posts/index.ctp instead of the one I placed in app/views/posts/xml/index.ctp .

Can anybody tell me what else I am missing here please?

Thank you

Answer 1

What version of cakePHP are you using? If you are using versions 2.x, the solution is very simple.

1. Make sure you include this line in your controller

    public $components = array('RequestHandler'); 

2. Go into your app/Config/routes.php and add the following lines BEFORE the line with require CAKE . 'Config' . DS . 'routes.php'; require CAKE . 'Config' . DS . 'routes.php'; :

    Router::mapResources('examples'); Router::parseExtensions('xml'); 

   Where examples is essentially just the name of your view.

3. Be sure to enter the your url with the xml extension.

    url/controller.xml 

This should do the trick. Including the RequestHandler component, when "used in conjunction with Router::parseExtensions() RequestHandler, will automatically switch the layout and view files to those that match the requested type"

Answer 2

Did you create an xml layout? You might need to just create a blank layout and in the view set the layout to the xml layout.

Answer 3

Try putting something like this in your controller function (or even better in the beforeFiler):

if(@($this->request->isXML() || $this->request->params['ext'] == 'xml')) {
    $this->RequestHandler->respondAs('xml');
}

Also make sure in Config/routes.php is

Router::parseExtensions('xml');
