具有基于方法类型的必需参数的Restler类

Question

Let's say I have this to use with my API classes

class EventInfo {
    /// @var int $start The Start time
    public $start

    /// @var string $url The URL for the event {@required false}
    public $url = null;
}

And now I want to use EventInfo for both my POST and my PATCH methods. When I'm doing a POST, $start is a required property to be set. The $url will come in as an optional parameter.

However, when I'm doing a PATCH operation, then $start should no longer be required. I might be passing a new start time, but I might not.

How do I specify this?

Answer 1

First, use the DocBlock syntax

class EventInfo {
    /**
     * @var int $start The Start time
     */
    public $start;

    /**
     * @var string $url The URL for the event {@required false}
     */
    public $url = null;
}

This sets the default required and optional properties. Then you can control the required properties at api method level using {@required } comment. See the example below

class Home
{
    public function index()
    {
        return array(
            'success' => array(
                'code' => 200,
                'message' => 'Restler is up and running!',
            ),
        );
    }

    public function patch(EventInfo $info)
    {
        return func_get_args();
    }

    /**
     * @param EventInfo $info {@required start,url}
     * @return array
     */
    public function post(EventInfo $info)
    {
        return func_get_args();
    }
}

You may also add {@properties start} comment similarly to restrict which properties are needed by the API method.
