Symfony session handler

Using Redis for session handling in Symfony 4.1+

These are defined in the handlers key of the configuration above and the classes behind the listed services must implement LogoutHandlerInterface.

Logout handlers should perform actions related to logging the user out.

For example, session based authentication might invalidate the session. In fact, this is something Symfony provides.

Configuring Sessions and Save Handlers

There can be multiple logout handlers in a given firewall. Multiple behaviors needed on logout? Build multiple handlers instead of trying to shove all the functionality into one. Logout sucess handlers must implement LogoutSuccessHandlerInterface. The default logout success handler generates a redirect to a taget url or path, specified like this in a security configuration:.

Symfony uses these two interfaces in its LogoutListener. A simplified version:. The logout success handler is invoked to generate a HTTP response object.

Then each logout handler is invoked with the incoming, logout HTTP request, the response, and the authentication token the logged in user. Use logout handlers when an application needs to perform some sort of cleanup when a user signs out.

I recently implemented a logout handler that invalidated all active access tokens on an internal facing OAuth authentication server. When a user logs out, they would be logged out of all applications calling into the OAuth server: a behavior we wanted to enforce.

A success handler should be implemented when some custom behavior needs to happen to generate a logout response. The same app that invalidated access tokens also needed some custom response behavior for logout: we needed to ensure the user was redirected to a URL stored in the database. The custom handler looked up the URL and generated redirect response. The default logout success handler generates a redirect to a taget url or path, specified like this in a security configuration: security When to Use Logout and Logout Success Handlers Use logout handlers when an application needs to perform some sort of cleanup when a user signs out.

Sessions are provided by the HttpFoundation componentwhich is included in all Symfony applications, no matter how you installed it. Before using the sessions, check their default configuration:. The session metadata files will be stored outside of the Symfony application, in a directory controlled by PHP.

Although this usually simplify things, some session expiration related options may not work as expected if other applications that write to the same directory have short max lifetime settings.

If you prefer, you can use the session. Check out the Symfony config reference to learn more about the other available Session configuration options. Also, if you prefer to store session metadata in a database instead of the filesystem, check out this article: How to Use PdoSessionHandler to Store Sessions in the Database.

Symfony provides a session service that is injected in your services and controllers if you type-hint an argument with SessionInterface :.

Every SessionInterface implementation is supported. If you have your own implementation, type-hint this in the argument instead. Stored attributes remain in the session for the remainder of that user's session. By default, session attributes are key-value pairs managed with the AttributeBag class. If your application needs are complex, you may prefer to use namespaced session attributes which are managed with the NamespacedAttributeBag class.

Before using them, override the session service definition to replace the default AttributeBag by the NamespacedAttributeBag :. Sessions are automatically started whenever you read, write or even check for the existence of data in the session. This may hurt your application performance because all users will receive a session cookie. In order to prevent that, you must completely avoid accessing the session. For example, if your templates include some code to display the flash messagessessions will start even if the user is not logged in and even if you haven't created any flash messages.

To avoid this behavior, add a check before trying to access the flash messages:. Disneyland Paris Dec. Lille France February 28 Paris France TBA. Warszawa Poland October Berlin Germany Oct.

Rather than using the regular session handler, you can create a custom save handler by defining a class that extends the SessionHandlerProxy class. Then, define the class as a service. If you're using the default services. Finally, use the framework. Keep reading the next sections to learn how to use the session handlers in practice to solve two common use cases: encrypt session information and define read-only guest sessions. If you want to encrypt the session data, you can use the proxy to encrypt and decrypt the session as required.

The following example uses the php-encryption library, but you can adapt it to any other library that you may be using:. There are some applications where a session is required for guest users, but where there is no particular need to persist the session. In this case you can intercept the session before it is written:.

The SessionServiceProvider provides a service for storing data persistently between requests. In case of the default NativeSessionStoragethe most useful options are:. However, all of these are optional. Default Sessions life time is seconds 30 minutes.

To override this, set the lifetime option. For a full list of available options, read the PHP official documentation. Instance of AttributeBagInterface. Instance of FlashBagInterface. The default session handler is NativeFileSessionHandler.

However, there are multiple handlers available for use by setting session. The Session provider provides a session service.

Here is an example that authenticates a user and creates a session for them:. If your system is using a custom session configuration such as a redis handler from a PHP extension then you need to disable the NativeFileSessionHandler by setting session.

It is suggested you use choose one of the following Symfony Custom Save Handlers :. In order to access your session data in Ratchet, you must also use the same Symfony Session Handler on your web site. Below is a network diagram of how the various connections interact to access data:. Important: Sessions through WebSockets work as they do through a traditional web server; a cookie is set and transmitted in each request header.

This means that your web site and your WebSocket server both must have access to the cookie. In order for session data to be shared between your web site and your WebSocket server they must be on the same domain. You can achieve this by either hosting them on the same domain and different ports, such as mydomain. If you choose to host the WebSocket server on a sub-domain websocket.
