这里trait完全模拟了laravel路由器的运行控制器(包括对中间件和依赖注入的支持)。仅在5.4版本中测试

<?php

namespace App\Traits;

use Illuminate\Pipeline\Pipeline;
use Illuminate\Routing\ControllerDispatcher;
use Illuminate\Routing\MiddlewareNameResolver;
use Illuminate\Routing\SortedMiddleware;

trait RunsAnotherController
{
    public function runController($controller, $method = 'index')
    {
        $middleware = $this->gatherControllerMiddleware($controller, $method);

        $middleware = $this->sortMiddleware($middleware);

        return $response = (new Pipeline(app()))
            ->send(request())
            ->through($middleware)
            ->then(function ($request) use ($controller, $method) {
                return app('router')->prepareResponse(
                    $request, (new ControllerDispatcher(app()))->dispatch(
                    app('router')->current(), $controller, $method
                )
                );
            });
    }

    protected function gatherControllerMiddleware($controller, $method)
    {
        return collect($this->controllerMidlleware($controller, $method))->map(function ($name) {
            return (array)MiddlewareNameResolver::resolve($name, app('router')->getMiddleware(), app('router')->getMiddlewareGroups());
        })->flatten();
    }

    protected function controllerMidlleware($controller, $method)
    {
        return ControllerDispatcher::getMiddleware(
            $controller, $method
        );
    }

    protected function sortMiddleware($middleware)
    {
        return (new SortedMiddleware(app('router')->middlewarePriority, $middleware))->all();
    }
}

然后将它添加到类中并运行控制器。注意，依赖注入将与当前路由一起分配。

class CustomController extends Controller {
    use RunsAnotherController;

    public function someAction() 
    {
        $controller = app()->make('App\Http\Controllers\AnotherController');

        return $this->runController($controller, 'doSomething');
    }
}

class CustomController extends Controller {
    use RunsAnotherController;

    public function someAction() 
    {
        $controller = app()->make('App\Http\Controllers\AnotherController');

        return $this->runController($controller, 'doSomething');
    }
}

namespace App\Http\Controllers;

//call the controller you want to use its methods
use App\Http\Controllers\AdminController;

use Illuminate\Http\Request;

use App\Http\Requests;

class MealController extends Controller
   {
      public function try_call( AdminController $admin){
         return $admin->index();   
    }
   }

如果您在另一个控制器中需要该方法，这意味着您需要抽象它并使其可重用。将该实现移动到服务类(ReportingService或类似的东西)并将其注入到控制器中。

例子:

class ReportingService
{
  public function getPrintReport()
  {
    // your implementation here.
  }
}
// don't forget to import ReportingService at the top (use Path\To\Class)
class SubmitPerformanceController extends Controller
{
  protected $reportingService;
  public function __construct(ReportingService $reportingService)
  {
     $this->reportingService = $reportingService;
  }

  public function reports() 
  {
    // call the method 
    $this->reportingService->getPrintReport();
    // rest of the code here
  }
}

对需要该实现的其他控制器执行相同的操作。从其他控制器中获取控制器方法是一种代码气味。

你可以在PrintReportController中使用一个静态方法，然后像这样从SubmitPerformanceController调用它;

namespace App\Http\Controllers;

class PrintReportController extends Controller
{

    public static function getPrintReport()
    {
      return "Printing report";
    }


}



namespace App\Http\Controllers;

use App\Http\Controllers\PrintReportController;

class SubmitPerformanceController extends Controller
{


    public function index()
    {

     echo PrintReportController::getPrintReport();

    }

}

\App::call('App\Http\Controllers\MyController@getFoo')
