…is because I want you to know what it is if you see it, and, it leads us towards a few other interesting things. Let's play a little bit in security.yaml. Under access_control add a new entry with path ^/account. Yes…

…so let's demystify something else, something that's already been happening behind the scenes. First commit everything, with a nice message: Let's install a new feature called the Symfony Security Checker. This is a great tool.... but... full disclosure: we're mostly installing…

…ways... an even better and more common example. Here's the setup: we're going to need a lot of dinosaurs, a lot of enclosures and even more security. Instead of creating these by hand each time a new batch of adorable dinosaurs arrives, let…

…The bundle does not provide any authentication. Open app/config/security.yml. The form_login authentication mechanism we're using is core to Symfony itself, not this bundle. So, one of the questions we get a lot is: how can I use Guard authentication with…

…let's lock down the actual controller action. How? Now we know two ways: by overriding the editAction() in UserController and adding a security check or by adding a PRE_EDIT event listener. Let's use events! Subscribe to a second event: EasyAdminEvents::PRE_EDIT…

…easy because we're using Guard authentication. Inside of UserController, instead of redirecting to the home page: do this: return $this->get() to find a service called security.authentication.guard_handler. It has a method on it called authenticateUserAndHandleSuccess(). I'll clear the arguments and…

…way. We need to be able switch to that user's account: we need to impersonate them. Setting up impersonation is super easy. In security.yml, under your firewall, add a new key called switch_user set to ~ to activate the system: Now, on…

…user has a role, you'll always use one service: the authorization checker. It looks like this: if (!$this->get('security.authorization_checker')->isGranted('ROLE_ADMIN'). So, if we do not have ROLE_ADMIN, then throw $this->createAccessDeniedException(): That message is just for us developers…

…But, it is not setting the last username on the session... because it doesn't really know where to look for it. No worries, fix this with $request->getSession()->set() and pass it the constant - Security::LAST_USERNAME - and $data['_username']: Now, try it again…

…for user AppBundle\Entity\User. What the heck is a user provider and why do we need one? A user provider is one of the most misunderstood parts of Symfony's security. It's an object that does just a few small jobs for you…

…Great! This template also has a bunch of boilerplate code, so copy that from the docs too. Paste it here. Update the form action route to security_login: Well, it ain't fancy, but let's try it out: go to /login. There it is…

…unless I'm an admin... who can view anyone's page. This is a classic situation where security isn't global, it's dependent on the object being accessed. I can see my user page but not your user page. This is the perfect case…

…OR, use a cool trick from SensioFrameworkExtraBundle. Give the controller class a doc-block and a new annotation: @Security. Auto-complete that to get the use statement. Then, add "is_granted('ROLE_USER')": Now we're requiring a valid user on every endpoint. Re-run…

…authenticator. Set its class to AppBundle\Security\JwtTokenAuthenticator: And instead of adding an arguments key: here's your permission to be lazy! Set autowire to true to make Symfony guess the arguments for us. Finally, copy the service name and head into security.yml. Under…

…it alone: Copy that name and run it: Instead of the 201, we get a 200 status code after being redirected to /login. I know we don't have our security system hooked up yet, but pretend that it is hooked up and working nicely…

…your app just by throwing the special AccessDeniedException. Since we’ll need the same security logic in editAction, updateAction and deleteAction, let’s create a private function called enforceOwnerSecurity that holds it: // src/Yoda/EventBundle/Controller/EventController.php // ... use Symfony\Component\Security\Core\Exception\AccessDeniedException…

…firewall and giving it a secret, random key: # app/config/security.yml security: Tip You can also use a secret parameter from parameters.yml as a remember me key to centralize secret key management for the entire application. Next, open the login template and add…

…in a Controller¶ From a controller, it’s just as easy. Go to the controller function for the homepage and grab an object called the security context. Then call getToken() and getUser(): public function indexAction() { } Actually, since this is a bit long, the Symfony base…

… To fix this, add a new access_control entry above this for any page starting with /login. For the role, type IS_AUTHENTICATED_ANONYMOUSLY: # app/config/security.yml security: Refresh again. It works! We’re missing our styles, but we’ll fix that next. The…

…let’s relax a little and have some fun. In this last part, we’ll check out some cool things related to forms and security. Form Field Guessing¶ Remember when we disabled HTML5 validation earlier. Let’s add it back temporarily. Remove the novalidate attribute…
