Routing in Magento 2 – Sample 1

We can easily claim that routing in Magento is just one of the absolute most vital parts. Complete application (Magento 2) flow relies on handling link ask for and also modem classes which are actually responsible for matching and also refining that asks for. This post deals with modems flow in Magento 2 and also evaluations some modems that feature nonpaymentinstallation Also it is going to be actually demonstrated how to develop one customized modem. It are going to be actually pointed out just how modems match action (Controller class), and also a lot more details concerning Controllers is going to be actually covered in an apart post.

Routing flow

First, we need to examine full routing flow, so our team can easily get in additional particulars for each component eventually. As our team presently recognize, Magento 2 generates HTTP application in which class (launch method) ask for flow are going tostart Our flow begins along with developing front controller:

$frontController  = $this->> _ objectManager->>get('Magento Framework App FrontControllerIn terface');

Front controller is actually responsible for knotting canal all on call modems and also matching responsible modem for present ask for. We’ll deal with Front Controller in particulars little bit eventually. For right now, to know full flow it is very important to recognize just how application matches modems. Routers list is actually developed in Router List (named in Front Controller for knotting on modems) class, positioned in Magento Framework App, and also this class is actually responsible for buying and also model on modemslist Router class is actually responsible for matching if modem is actually responsible for present ask for. Let’s take a look at Magento 2 flow:

index.php (operates bootstrap and also develop HTTP application) → HTTP application → FrontController → Routing → Controller handling → etc

Now our team’ll examine every component of routing flow for much better understanding of routing in Magento 2.

Front Controller

Same as in Magento 1, this is actually entrance routing factor which is actually contacted at HTTP application launch (launch method). It’s responsible for matching modem which is actually responsible for present ask for. It’s positioned under lib/internal/Magento/Framework/App/FrontController php. You can easily find that at HTTP launch method FrontControllerIn terface is actually made use of. Let’s consider that in code:

class Http implements Magento Framework AppIn terface.
 {
    public function launch()
     
         ...
        	//Here Application is calling front controller and it's dispatch method
        $frontController  = $this->> _ objectManager->>get('Magento Framework App FrontControllerIn terface');
        $result  = $frontController->> dispatch($this->> _ ask for);
         ...
     
} 

Now, when we understand just how and also when front controller is actually contacted, allow’s check out at Front controller class and also eliminate method on its own:

lib/internal/Magento/Framework/App/FrontController php.
class FrontController implements FrontControllerIn terface.
 {
    public function dispatch( RequestIn terface $ request)
     {.
Magento Framework Profiler:: start(' routers_match');
        $ routingCycleCounter  =  0;
        $result  =  null;
        while (!$ request->> isDispatched() &&& & $ routingCycleCounter<++    _ routerList as $ router
            )Magento {Framework {App$RouterIn stance
             = $ router->>this match($ request );  if
                try (
                    $actionIn stance )   $ request ->> setDispatched();
                    $  stance- >actionIn() - >
                         setNoCacheHeaders( ) ;true$ =
                        $ actionIn stance- >getResponse dispatch($ request>); break ;
                        result } ((* )actionIn    Found$ e )  } }
                       setAction (* )::(' routers_match' (* )) ; if 
                     ( $routingCycleCounter >(* )100 (* )) false throw new (* ) Logic 
                     ('
                 reached 100 router match iterations' 
             )
        ; Magento$ Framework;Profiler}(* )} stop we can see, dispatch  will trough all routers (enabled, we'll cover later 
         router configuration) until one router is matched and request is dispatched ($ request → setDispatched ( );-RRB- or routing cycle counter exceeds 100.  can be matched, but if there is no dispatch it will repeat the   trough routers (  forward )., router can be redirected and dispatched or it can be matched and processed.   is explained at request 
            . , we can  forward to see how router matching( matchException) works and what exactly are routers., router is PHP Front controller for matching and processing URL request.  default, there are some routers framework and 
         core like;
        return , result, 
     and
 

As’ll cover all of them all, detailing their objective and also just how they operate. method are actually applying loop terface.this, allow’s check out at thein of nonpayment modems: true → CMSRouter →loop →action(Also is actually modemsRouters list class– flow:: eliminate() )Now at move/method/
