使用FOSRestBundle的Symfomy2手动路由定义

Question

I am now using the FOSRestBundle in order to build a REST API within my Symfony application. The idea for now is to list some locations(hotels, restaurants...), I managed to configure the automatic routes with FOSRestBundle like:

/api/locations , /api/locations/{id} , /api/locations/{name}/detail

with this controller:

class LocationController extends FOSRestController implements ClassResourceInterface
{

/**
 * GET /locations 
 *
 * @return Array
 *
 */
public function cgetAction()
{
    $locations = $this->getDoctrine()
              ->getManager()
              ->getRepository('VisitBILocationsBundle:Location')
              ->findAll(); 

    if (!$locations) {
        return array(
            'locations' => $locations,
            'status' => 1
        );
    }

    return array(
            'locations' => $locations,
            'status' => 0
        );
}

/**
 * GET /locations/{locationId} 
 *
 * @return Array
 *
 */
public function getAction($id)
{
    $location = $this->getDoctrine()
              ->getManager()
              ->getRepository('VisitBILocationsBundle:Location')
              ->findBy(array('id' => $id));

    if (!$location) {
        return array(
            'location' => $location,
            'status' => 1
        );
    }

    return array(
            'location' => $location,
            'status' => 0
    );       
}

/**
 * GET /locations/{name}/detail 
 *
 * @return Array
 */
public function getDetailAction($name)
{

    $detail = $this->getDoctrine()
             ->getManager()
             ->getRepository('VisitBILocationsBundle:LocationDetail')
             ->findBy(array('name' => $name));

    if (!$detail) {
        return array(
            'locationDetail' => $detail,
            'status' => 1
        );
    }

    return array(
            'locationDetail' => $detail,
            'status' => 0
    );      
}


}

I've been struggling with this, but would anyone know how should I proceed to generate one custom url like this:

/api/locations/nearby/{latitude}/{longitude}

The idea is that I would provide my own latitude and longitude, and the backend will calculate and provide the locations which are the closest to me.

Of course I've looked at the documentation of FOSRestBundle for manual route configuration, but since I spent some time trying to do it, I come here to ask for some help :)

Answer 1

OK here is how to proceed, works fine for me:

I use the annotation system to route /locations/nearby/{latitude}/{longitude}

/**
 * Return a nearby location
 * @Get("/locations/nearby/{latitude}/{longitude}", requirements={"latitude" = "[-+]?(\d*[.])?\d+", "longitude" = "[-+]?(\d*[.])?\d+"})
 */
public function nearbyAction($latitude, $longitude) {...}

Then I have to specify float numbers with: requirements={"latitude" = "[-+]?(\d*[.])?\d+", "longitude" = "[-+]?(\d*[.])?\d+"}

Those will still be interpreted as string by the controller: "64.1333", I just have to use this in the controller:

floatval($latitude)

to get url parameters as float and then do my calculations!
