Symfomy2 manual route definitions with FOSRestBundle - php

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

If you want to manually define a route, it should just be as simple as adding the route to the existing routing configuration. How exactly you do it depends on how you're handling the routing configuration: annotation, yaml, or xml.
Option 1: YAML
In the routing.yml file (ex: src/Vendor/MyBundle/Resources/config/routing.yml) add something like:
location_nearby:
pattern: /api/locations/nearby/{latitude}/{longitude}
defaults: { _controller: "MyBundle:Location:nearby" }
requirements:
_method: GET
which would correspond to this method in LocationController:
public function nearbyAction($latitude, $longitude) { ... }
Option 2: Annotations
Add this use statement to the Controller file:
use FOS\RestBundle\Controller\Annotations\Get;
and then define the route above the controller method:
/**
* Return a nearby location
* #Get("/api/locations/nearby/{latitude}/{longitude}")
*/
public function nearbyAction($latitude, $longitude) { ... }

Answer 2

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!
