Apa iku middleware ing Laravel?

Question

Accepted Answer

**Middleware** nyedhiyakaké mekanisme kanggo **ngsaring lan ngolah HTTP requests** sing mlebu ing aplikasine — nglancirkaké kode sadurunge (lan opsional sawisé) request teka ing controller. Iki digunakake kanggo cross-cutting concerns kaya authentication, logging, CORS, lan rate limiting. ## Kepiye middleware bisa gumana ```php age < 18) { return redirect('/home'); // BLOCK — short-circuit, don't proceed } return $next($request); // PASS the request to the next layer/controller } } ``` Middleware nampa request lan closure `$next`. Kode sadurunge `$next($request)` mlaku ing cara **in**; nggilani `$next` nglancirkaké kontrol menyang ngarep; sampeyan bisa uga tumindak ing response sawise. Middleware bisa **short-circuit** (mulihna response tanpa ngilani `$next`, conto blokir request sing ora sah). ## Nglampirake middleware ```php // to a route Route::get('/admin', ...)->middleware('auth'); // to a group of routes Route::middleware(['auth', 'verified'])->group(function () { ... }); // globally (every request) — registered in the HTTP kernel / bootstrap ``` Middleware nglampir per-route, per-group, utawa globally. Middleware pirang-pirang mlaku ing urutan (pipeline). ## Middleware sing wis ana (Laravel nyedhiyakaké akeh) ```text auth → require authentication (redirect/401 if not logged in) verified → require a verified email throttle:60,1 → rate limiting (60 requests per minute) guest → only for non-authenticated users can:update,post → authorization check + CSRF protection, CORS, etc. run as middleware automatically ``` Laravel kiriman middleware kanggo kabutuhan sing paling umum — `auth` (workhorse kanggo njaga routes), rate limiting, CSRF, lan liyané. ## Apa sing penting Middleware punika konsep Laravel sing penting kanggo nangani **cross-cutting concerns** kanthi bersih — logika sing kudu mlaku kanggo kathah requests, kaya authentication, authorization, logging, rate limiting, lan CORS. Paham babagan iki penting amarga iku cara Laravel applications saring lan njaga requests: built-in **`auth` middleware** punika cara standar kanggo njaga routes (merlokake login), `throttle` nyedhiyakaké rate limiting, lan perlindungan CSRF mlaku minangka middleware kanthi otomatis — dadi middleware dadi pondasi security lan behavior aplikasi inti. \ Ngerti kepiye middleware bisa gumana (request/`$next` pipeline, kemampuan kanggo short-circuit kanthi mulih response kanggo blokir requests) lan kepiye nglampirake (per-route, per-group, globally) iku dhasar kanggo struktur aplikasi kanthi bener — nglakokake cross-cutting logic ing middleware tinimbang ngulang-ulang ing saben controller. Middleware punika papan Laravel nangani request-level concerns sing nglampir ing akeh routes, nggawaké penting, kasowan-kasowan pengetahuan kanggo nggawe aplikasi sing aman, well-structured — luwih-luwih middleware auth kanggo njaga routes, sing mbok mung kabeh aplikasi nyata nggunakake. Paham pipeline middleware uga tulung sampeyan nulis custom middleware kanggo application-specific request processing.
