Laravel: He aha nga Kaiwhakahaere Laravel

I roto i te anga MVC, ko te reta "C" e tu ana mo nga Kaiwhakahaere, a i roto i tenei tuhinga ka kite tatou me pehea te whakamahi i nga Kaiwhakahaere i Laravel. Ka noho tika i waenga i nga tirohanga me nga tauira. I roto i tenei tuhinga ka kite tatou me pehea te hanga me te whakarite i nga kaiwhakahaere i Laravel.

Creare un controller i roto i te laravel

Hei hanga a controller, me whakatuwhera e matou te whakahau whakahau, te tauranga ranei, kia rite ki te punaha whakahaere e whakamahia ana e matou, ka patohia te whakahau e whai ake nei hei hanga i te kaiwhakahaere ma te whakamahi Artisan CLI (Command Line Interface).

php artisan make:controller <controller-name> --plain

Whakakapi <controller-name> me to ingoa controller. Ma tenei ka hanga he controller. Ko te controller ka taea te tiro ki roto app/Http/Controllers .

Ka kite koe kua oti kee te mahi mo koe etahi o nga tohu ka taea e koe te taapiri i a koe ake tohu tohu. Ko te controller ka taea te karanga mai i te web.php me te syntax e whai ake nei.

wetereo

Route::get(‘base URI’,’controller@method’);

tauira

1 : Whakahaerehia te whakahau e whai ake nei hei waihanga MyController

php artisan make:controller MyController

2 – I muri i te mahi angitu, ka whiwhi koe i te putanga e whai ake nei.

3 – Ka kitea e matou te kaiwhakahaere i hangaia i roto app/Http/Controller/MyController.php me etahi waehere taketake kua tuhia, ka taea e taatau te whakarereke ina hiahiatia.

Pūwhakahaere waenga

Kua kite tatou i te middleware a ka taea hoki e tatou te whakamahi me te controller. Ko te middleware ka taea hoki te tautapa ki te ara kaiwhakahaere, ki roto ranei i te kaihanga kaiwhakahaere. Ka taea e koe te whakamahi i te tikanga middleware to assign the middleware al controller. Ko te middleware ka taea hoki te rehita ki etahi tikanga o te controller.

Tautapa i te middleware ki te ara

Route::get('profile', [
   'middleware' => 'auth',
   'uses' => 'UserController@showProfile'
]);

I konei kei te tautapahia e matou te taputapu waenga motuhēhēnga ki te KaiwhakamahiKaiwhakahaere i te ara kōtaha.

Taumahi Middleware i roto i te kaihanga kaiwhakahaere

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class MyController extends Controller {
   public function __construct() {
      $this->middleware('auth');
   }
}

I konei ka tohua e matou te middleware o motuhēhēnga te whakamahi i te tikanga middleware i roto i te kaihanga MyController .

Kia mahara $this->middleware() mahi te reira takitahi ki te tautapa koe i roto i te kaihanga. Mena ka waea tatou $this->middleware() mai i tetahi tikanga whakahaere motuhake, kare e maka he hapa engari karekau te middleware e mahi.

He tika tenei whiringa, engari fakatāutaha pai ake ahau ki te hoatu i te middleware katoa i roto i te routes, no te mea he maamaa ake te waahi ki te rapu mo nga mea katoa middleware.

tauira

1 – Me taapiri nga rarangi waehere e whai ake nei ki te konae route/web.php a ka whakaora matou.

<?php
Route::get('/mycontroller/path',[
   'middleware' => 'First',
   'uses' => 'MyController@showPath'
]);

2 – Me hanga he middleware ingoa FirstMiddleware ma te whakahaere i te rarangi waehere e whai ake nei.

php artisan make:middleware FirstMiddleware

3 : tāpirihia te waehere e whai ake nei i roto i te tikanga hapai Tuhinga o mua FirstMiddleware hanga noa i roto taupānga/Http/Middleware .

<?php

namespace App\Http\Middleware;
use Closure;

class FirstMiddleware {
   public function handle($request, Closure $next) {
      echo '<br>First Middleware';
      return $next($request);
   }
}

4 – Me hanga he middleware ingoa SecondMiddleware ma te whakahaere i te whakahau e whai ake nei.

php artisan make:middleware SecondMiddleware

5 : me tapiri te waehere e whai ake nei i roto i te tikanga kakau o te SecondMiddleware hanga noa i roto taupānga/Http/Middleware .

<?php

namespace App\Http\Middleware;
use Closure;

class SecondMiddleware {
   public function handle($request, Closure $next) {
      echo '<br>Second Middleware';
      return $next($request);
   }
}

6 : me hanga he controller ingoa MyController ma te whakahaere i te rarangi e whai ake nei.

php artisan make:controller MyController

7 - I muri i te mahi angitu o te URL, ka whiwhi koe i nga putanga e whai ake nei -

8 – Tāruahia te waehere e whai ake nei ki te konae app/Http/MyController.php.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class MyController extends Controller {
   public function __construct() {
      $this->middleware('Second');
   }
   public function showPath(Request $request) {
      $uri = $request->path();
      echo '<br>URI: '.$uri;
      
      $url = $request->url();
      echo '<br>';
      
      echo 'URL: '.$url;
      $method = $request->method();
      echo '<br>';
      
      echo 'Method: '.$method;
   }
}

9 – Inaianei me timata te tūmau tukutuku php ā-roto mā te whakahaere i te whakahau e whai ake nei, mena kare ano koe.

php artisan serve

10 – Tirohia te URL e whai ake nei.

http://localhost:8000/mycontroller/path

11 – Ko te putanga ka puta mai i te ahua e whai ake nei.

Tata ki nga taputapu waenga e rua ka uru, engari kotahi anake

Controller di restful resource

I te nuinga o nga wa ka hangaia he tono me mahi koe CRUD (Create, Read, Update, Delete) . Ma Laravel e ngawari tenei mahi. Hanga noa he controller a ka tukuna aunoatia e Laravel nga tikanga katoa mo nga mahi CRUD. Ka taea hoki te tuhi i tetahi ara ki nga tikanga katoa i roto i te konae route.php.

tauira

1 : hanga he kaiwhakahaere e kiia nei MyController ma te whakahaere i te whakahau e whai ake nei.

php artisan make:controller MyController

2 : tāpirihia te waehere e whai ake nei app/Http/Controllers/MyController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class MyController extends Controller {
   public function index() {
      echo 'index';
   }
   public function create() {
      echo 'create';
   }
   public function store(Request $request) {
      echo 'store';
   }
   public function show($id) {
      echo 'show';
   }
   public function edit($id) {
      echo 'edit';
   }
   public function update(Request $request, $id) {
      echo 'update';
   }
   public function destroy($id) {
      echo 'destroy';
   }
}

3 – Me taapiri te rarangi waehere e whai ake nei ki te konae routes/web.php .

Route::resource('my','MyController');

4 – Kei te rehita matou i nga tikanga katoa o MyController ma te rehita i tetahi kaiwhakahaere whai rauemi. Kei raro ko te ripanga o nga mahi e whakahaerehia ana e te kaiwhakahaere rauemi.

Poaka	Ara	Mahi	Ingoa Ara
GET	/ taku	taupū	taku taurangi
GET	/taku/hanga	waihanga	taku.hanga
POST	/ taku	toa	taku toa
GET	/taku/{taku}	whakaatu	taku.whakaatu
GET	/my/{my}/edit	whakatika	taku.whakatika
PUT/PATCH	/taku/{taku}	whakahou	taku.whakahou
DELETE	/taku/{taku}	whakangaro	toku. whakangaro

5 – Ngana ki te whakahaere i nga URL e whakaatuhia ana i te ripanga i raro nei.

URL	Descrizione	Atu
http://localhost:8000/my	Whakahaerehia te tikanga taurangi o MyController.php	taupū
http://localhost:8000/my/create	Whakahaerehia te tikanga hanga o MyController.php	te whakauru
http://localhost:8000/my/1	Whakahaerehia te tikanga whakaatu o MyController.php	whakaatu
http://localhost:8000/my/1/edit	Whakahaerehia te tikanga whakatika o MyController.php	whakatika
