laravel 5 middleware with parameters - php

Question

I'm an absolute beginner in Laravel 5.
I've created a middleware class called BeforeMiddleware the blueprint of that class is below.
class BeforeMiddleware {
public function handle($request, Closure $next, $role)
{
if($request->user()->hasRole($role)){
return redirect('/pensions');
}
return $next($request);
}
}
registered in kernel.php as
protected $routeMiddleware = [
'auth' => 'App\Http\Middleware\Authenticate',
'auth.basic' => 'Illuminate\Auth\Middleware\AuthenticateWithBasicAuth',
'guest' => 'App\Http\Middleware\RedirectIfAuthenticated',
'role' => 'App\Http\Middleware\BeforeMiddleware',
];
User model is below
class User extends Model {
public function hasRole($name)
{
return ($this->role->name == $name) ? true : false;
}
public function role()
{
return $this->belongsTo('App\Models\Role');
}
}
and usage in routes.php is below.
Route:get('/reporting', [ 'middleware' => 'role:Owner', 'uses' => function(){
return 'secret data only be viewable by the owners';
}]);
If I open that in the browser /reporting I get the following error.
ReflectionException in Container.php line 776:
Class role:Owner does not exist
HOWEVER if I hard code 'Owner' in middleware and remove the $role parameter and also removed it from routes which now looks like this.
BeforeMiddleware.php
class BeforeMiddleware {
public function handle($request, Closure $next, $role)
{
if($request->user()->hasRole('Owner')){
return redirect('/pensions');
}
return $next($request);
}
}
routes.php
Route:get('/reporting', [ 'middleware' => 'role', 'uses' => function(){
return 'secret data only be viewable by the owners';
}]);
it works as desired...
therefore my question is how to pass that parameter when using middleware to control routes
Any Idea?

Answer 1

If you read carefully the Middleware Documentation, you will notice this line
Middleware parameters may be specified when defining the route by separating the middleware name and parameters with a :. Multiple parameters should be delimited by commas
So in your case if your middleware class is called BeforeMiddleware, the first part of middleware definition should be before then :, and after that you can define your route parameters, separated with comma, like this:
Route:get('/reporting', [ 'middleware' => 'before:Owner', 'uses' => function(){
return 'secret data only be viewable by the owners';
}]);

Since you are using Laravel 5.0, I suggest to just create separate middlewares for your roles.
Kernel.php
'owner' => 'App\Http\Middleware\OwnerMiddleware',
OwnerMiddleware
public function handle($request, Closure $next)
{
if($request->user()->hasRole('Owner')){
return redirect('/pensions');
}
return $next($request);
}
Then in routes.php
Route:get('/reporting', [ 'middleware' => 'owner', 'uses' => function(){
return 'secret data only be viewable by the owners';
}]);
