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');
    }
}

晚回复，但我一直在寻找这个时间。这现在可以用一种非常简单的方式实现。

如果没有参数

return redirect()->action('HomeController@index');

与参数

return redirect()->action('UserController@profile', ['id' => 1]);

文档:https://laravel.com/docs/5.6/responses # redirecting-controller-actions

在5.0中，它需要完整的路径，现在它简单多了。

尝试在SubmitPerformanceController中创建一个新的PrintReportController对象，并直接调用getPrintReport方法。

例如，假设我在SubmitPerformanceController中有一个名为“Test”的函数，然后我可以这样做:

public function test() { 
  $prc = new PrintReportController();
  $prc->getPrintReport();
 }

不建议从另一个控制器调用一个控制器，但是如果出于任何原因你必须这样做，你可以这样做:

Laravel 5兼容方法

return \App::call('bla\bla\ControllerName@functionName');

注意:这不会更新页面的URL。

最好是调用Route，让它调用控制器。

return \Redirect::route('route-name-here');

这种方法也适用于相同层次的Controller文件:

$printReport = new PrintReportController;

$prinReport->getPrintReport();
