我们首先创建一个需要绑定到服务容器的Test类:
<?php namespace App\Facades; class Test
{
public function doSomething()
{
echo 'This is TestClass\'s method doSomething';
}
}
然后创建一个静态指向Test类的门面类TestClass:
<?php namespace App\Facades; use Illuminate\Support\Facades\Facade; class TestClass extends Facade
{
protected static function getFacadeAccessor()
{
return 'test';
}
}
接下来我们要在服务提供者中绑定Test类到服务容器,修改TestServiceProvider类如下:
<?php namespace App\Providers; use Illuminate\Support\ServiceProvider;
use App\Services\TestService;
use App\Facades\Test; class TestServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{ } /**
* Register the application services.
*
* @return void
*/
public function register()
{
$this->app->singleton('test',function(){
//return new TestService();
return new Test;
}); $this->app->bind('App\Contracts\TestContract',function(){
return new TestService();
});
}
}
再然后需要到配置文件config/app.php
中注册门面类别名:
'aliases' => [ ...//其他门面类别名映射 'TestClass' => App\Facades\TestClass::class,
],
最后修改TestController代码如下:
<?php namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Http\Requests;
use App\Http\Controllers\Controller; use App;
use TestClass;
use App\Contracts\TestContract; class TestController extends Controller
{ public function __construct(TestContract $test){
$this->test = $test;
} /**
* Display a listing of the resource.
*
* @return Response
*/
public function index()
{
// $test = App::make('test');
// $test->callMe('TestController');
//$this->test->callMe('TestController'); TestClass::doSomething();
} ...//其他方法
}
注意:不要忘了在调用门面类TestClass的文件顶部使用
use TestClass;
引入TestClass,否则将不能正确调用。
好了,我们可以去浏览器中测试了,访问http://laravel.app:8000/test
,页面将会输出:
