Laravel 5.3：本地主机重定向您太​​多次

Question

I have 2 user roles which is superadmin and admin

I don't want admin to access of Settings Page.

I am not sure if this is the proper way.

---

So, here's my SettingsController.php

class SettingsController extends Controller {
    public function index() {
        if(Auth::user()->roles == 0) {
            return redirect(url()->previous());
        } else {
            return view('settings.index');
        }
    }
}

As you can see if the roles is 0. I redirect the user to the last page they're in. I also tried to use return back() ;

web.php (routes)

<?php

Route::get('/', ['uses' => 'UsersController@index']);
Route::post('login', ['uses' => 'UsersController@login']);

Route::group(['middleware' => ['auth']], function() {
    Route::get('logout', ['uses' => 'UsersController@destroy']);
    Route::get('upline', ['uses' => 'UplinesController@index']);
    Route::get('upline/create', ['uses' => 'UplinesController@create']);
    Route::post('upline', ['uses' => 'UplinesController@store']);
    Route::delete('upline/destroy/{id}', ['uses' => 'UplinesController@destroy']);
    Route::put('upline/update/{id}', ['uses' => 'UplinesController@update']);
    Route::get('upline/getdownlines/{id}', ['uses' => 'UplinesController@getDownlines']);

    Route::get('downline', ['uses' => 'DownlinesController@index']);
    Route::post('downline', ['uses' => 'DownlinesController@store']);
    Route::delete('upline/destroy/{id}', ['uses' => 'DownlinesController@destroy']);
    Route::put('downline/update/{id}', ['uses' => 'DownlinesController@update']);

    Route::get('bonus', ['uses' => 'BonusController@index']);
    Route::post('bonus/csv', ['uses' => 'BonusController@fileUpload']);

    Route::get('settings', ['uses' => 'SettingsController@index']);
});

I have a 2nd question. Can I limit admin using middleware? If yes, how?

Any help would be appreciated.

Answer 1

Maybe the second option, " Limiting admin with middleware ". So you can try something like;

Route::group(['prefix' => 'admin', 'middleware' => 'auth'], function () {
    Route::get('/', 'DownlinesController@update');
});

Then

Route::group(['prefix' => 'super', 'middleware' => 'auth'], function () {
    Route::get('/', 'UplinesController@index');
});

Answer 2

As @michael s answer suggests use middleware, his answer fails to demonstrate on how to do it (mine too, I just added more text).

Note : Laravel is big because of its documentation, USE IT !

You have 2 (or more options):

• parameterized middleware
• 2 distinctive middlewares (one for admin, another for superadmin)

Note : use artisan to generate middleware from stubs, $ php artisan make:middleware MyNewShinyMiddleware

parametrized middleware (my pick)

Head to documentation and check out this .

Example shows exactly your problem.

public function handle($request, Closure $next, $role)
{
    if (! $request->user()->hasRole($role)) { //implement hasRole in User Model
        // Redirect... 
        // (use named routes to redirect or do 401 (unauthorized) because thats what is going on!
        // abort(401) // create view in /views/errors/401.blade.php
        // return redirect()->route('home');
    }

    //success user has role $role, do nothing here just go to another "onion" layer
    return $next($request);
}

2 distinctive middlewares

simply create two middlewares and hardcode your checking routine of roles (same as you do in your controller sample) except use $request->user() ...

(routes) web.php

Route::group(['middleware' => 'role:admin'], function () {...} //parametrized

Route::group(['middleware' => 'checkRoleAdmin'], function () {...}
Route::group(['middleware' => 'checkRoleSuper'], function () {...}

Note : role , checkRoleAdmin and checkRoleSuper are "named" middlewares and you need to register them in kernel.php

Another way is yo use gates or policies which make the best sense, since you are trying to limit user. Read more here .

I use middleware based ACL for really simple projects (like one admin and no real users).
I use gates based ACL for medium projects (1-2 roles).
I use policies based ACL for "huge" projects (many roles, many users).
