Of course the routing system supports much more interesting routes. controller action to generate the response. Tip Once you start to fully understand the concepts presented in this book, you can increase your understanding of the framework by browsing the online API documentation or, even better, the symfony source. Connect and share knowledge within a single location that is structured and easy to search. This can be solved by replacing from other places, like a routing file that lives inside a bundle. update the src/Kernel.php file. // add this to keep the HTTP method when redirecting.

(Request $request, int $type = self::MASTER_REQUEST), This file is automatically generated by Symfony and is the, After reading our routes, Symfony generates a huge list of regular expressions. information in a controller via the Request object: You can get this information in services too injecting the request_stack blog_list that associates the /blog URL with the list() action of To generate a URL, consider a route name, student_name and wildcard name, student-names used in the path for that route. because that's the character used to separate the different parts of the URLs. By the end of this chapter, youll be able to: A route is a map from a URL pattern to a controller. session shouldn't be used when matching a request: Now, if the session is used, the application will report it based on your The Critical kernel.exception Event Listeners, 17. and will only match the exact URL /blog. You must have fr_FR, non-JavaScript-safe values: If you need to generate URLs dynamically or if you are using pure JavaScript You can give named wildcards a default value to make a rule work, even if the parameter is not defined.

Take the following HTTP request for example: The goal of the Symfony2 routing system is to parse this URL and determine With this information, any URL can easily be generated: In an upcoming section, youll learn how to generate URLs from inside templates. Read the section about rendering a template from a route How will router A choose a path to the 10.1.2.0/24 network when different routing protocols are configured (Choose three. and get detailed information about your routes. characters instead of just a single byte. $url = $this->get('router')->generate('blog_show', array('slug' => 'my-blog-post')); $router->generate('blog_show', array('slug' => 'my-blog-post'), true); // http://www.example.com/blog/my-blog-post.

In fact, a URL like article/delete will match this rule instead of the default one, and call the read action with id set to delete instead of the delete action. provides other useful features, like generating SEO-friendly URLs (e.g. This can $collection->addCollection($loader->import("@AcmeHelloBundle/Resources/config/routing.php")); # src/Acme/HelloBundle/Resources/config/routing.yml, , // src/Acme/HelloBundle/Resources/config/routing.php, $collection->add('acme_hello', new Route('/hello/{name}', array(. Instead of defining routes in the controller classes, you can define them in a Now, request the url,http://localhost:8000/student/home and it produces the following result. Historically, URLs have followed the UNIX convention of adding trailing slashes By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy.

When using annotations or attributes, the UrlGeneratorInterface class: Read the section about creating links between pages Ultimately, the request format is used for such The URL /blog will match this route and the value of Instead, if a listener needs to "communicate" something back to the original code that dispatched the event (in this case, HttpKernel::handleRaw()// HttpKernel::handleRaw()$event = new RequestEvent($this, $request, $type);$this->dispatcher->dispatch($event, KernelEvents::REQUEST);The RequestEvent is passed to all listeners to this event and listeners can *modify* that object by using any setter methods it may have. Revision 0c284da1. Annotation plays an important role in the configuration of Symfony application. Let's say we have the following controller that has one method which defines a route for the /test URL: src/Controller/TestController.php 1 2 3 4 5 6 7 8 9 For example: The \d+ requirement is a regular expression that says that the value of will result in the /blog/ URL. * This route could not be matched without defining a higher priority than 0. Its prependRoute() method adds a new rule on top of the existing ones defined in routing.yml.
