How symfony2 works and how symfony2 works

How symfony2 works and how symfony2 works

1. routing is a one-to-one ing between program methods and URLs.

In the configuration file, placing frequently accessed routes in front can improve the routing matching efficiency.

2. route matching methods

• Annotation

Function that allows you to annotate the running status of a method.

Class UserController extends Controller {/*** @ Route ("/user/login") * @ Template () */public function loginAction () {// code }}

• Router. yml

Common configuration formats of symfony2

The two methods cannot be used at the same time.

3. URL Definition

Static and Dynamic URLs

<? Phpnamespace Scource \ WebBundle \ Controller; use Symfony \ Bundle \ FrameworkBundle \ Controller; use Sensio \ Bundle \ FrameworkExtraBundle \ Configuration \ Route; use Sensio \ Bundle \ FrameworkExtraBundle \ Template;Use Sensio \ Bundle \ FrameworkExtraBundle \ Configuration \ Method ;//Method is used in the following route definition

// Define the total router. If all the routes used in the current controller start with/page/*** @ Route ("/page ") */class DefaultController extends Controller {/*** @ Route ("/{page_num}", defaults = {"page_num": 1 }, requirements = {"page_num" = "\ d +"}) * @ Template () * @ Method ("get") * // The preceding annotations are not useless, it uses annotations to dynamically affect program code. After defining the overall route, you can define only the second-level route when defining the current route. // defaults = {"page_num ": 1} set the default value of page_num to 1 // requirements = {"page_num" = "\ d +"}. The value of page_num must be a number // http: // localhost: 8000/app_dev. Php/page/555 public function indexAction ($ page_num) {$ method = $ this-> getRequest ()-> getMethod (); // return array ('name' => $ page_num);}/*** @ Route ("/test", name = "page_test ") * @ Template () * // name = "page_test" set the route name // use the command line> php app/console router: match/page/test can query the route information of/page/test // http: // localhost: 8000/page/test? Name = world public function testAction () {$ name = $ this-> getRequest ()-> get ('name '); // get the value of the temporary pass parameter return array ('name' => $ name );}}
