[PHP知识库]Laravel自定义门面

目录

1、app/Services 目录下创建TestService

2、app目录下创建Facades目录，并创建类Test

3、创建服务提供者

4、? TestServiceProvider.php中的boot方法中为实例绑定别名

5、config/app.php文件中注册服务提供者、门面别名

6、控制器中调用

?7、结果显示

1、app/Services 目录下创建TestService

app目录下新增Services 目录，并在此目录下新增clss类 TestServices

TsetServices.php

<?php


namespace App\Services;


class TestServices
{
    public function callMe($controller)
    {
        dd('call Me From TestSrvicesProvider In'.$controller);
    }

}

2、app目录下创建Facades目录，并创建类Test

Test.php

<?php


namespace App\Facades;

use Illuminate\Support\Facades\Facade;
class Test extends Facade
{
    protected static function getFacadeAccessor()
    {
        return 'test';
    }

}

3、创建服务提供者

php artisan make:provider TestServiceProvider

4、? TestServiceProvider.php中的boot方法中为实例绑定别名

/**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot()
    {
        //使用singleton 绑定单例
        $this->app->singleton('test',function (){
            return new TestServices();
        });

    }

5、config/app.php文件中注册服务提供者、门面别名

'providers' => [

        /*
         * Laravel Framework Service Providers...
         */
        Illuminate\Auth\AuthServiceProvider::class,
        

        /*
         * Package Service Providers...
         */

        /*
         * Application Service Providers...
         */
        App\Providers\AppServiceProvider::class,
        App\Providers\AuthServiceProvider::class,
        // App\Providers\BroadcastServiceProvider::class,
        App\Providers\EventServiceProvider::class,
        App\Providers\RouteServiceProvider::class,
        //新注册的服务提供者
        App\Providers\TestServiceProvider::class,

    ],
 'aliases' => [

        'App' => Illuminate\Support\Facades\App::class,
        // 'Redis' => Illuminate\Support\Facades\Redis::class,
        'Request' => Illuminate\Support\Facades\Request::class,
        'Response' => Illuminate\Support\Facades\Response::class,
        'Route' => Illuminate\Support\Facades\Route::class,
        'Schema' => Illuminate\Support\Facades\Schema::class,
        'Session' => Illuminate\Support\Facades\Session::class,
        'Storage' => Illuminate\Support\Facades\Storage::class,
        'Str' => Illuminate\Support\Str::class,
        'URL' => Illuminate\Support\Facades\URL::class,
        'Validator' => Illuminate\Support\Facades\Validator::class,
        'View' => Illuminate\Support\Facades\View::class,

        //新注册的门面别名Test
        'Test'=>\App\Facades\Test::class,

    ],

6、控制器中调用

（1）新建TestController

php artisan make:controller TestController

(2)控制器中调用门面

<?php


namespace App\Http\Controllers;


use App\Facades\Test as TestFacade;
use Illuminate\Http\Request;

class TestController extends Controller
{
    public function index(Request $request)
    {
        TestFacade::callMe('123');

    }
    public  function test()
    {
        $strNew ="欢迎来到Laravel的世界。" ;
        return $strNew;
    }


}

（3）定义路由：web.php

Route::get('/test',[\App\Http\Controllers\TestController::class,'index']);

至此Laravel的自定义门面就结束了，谢谢大家的观看。
