Laravel-authz is an authorization library for the laravel framework.
It's based on Casbin, an authorization library that supports access control models like ACL, RBAC, ABAC.
All you need to learn to use Casbin first.
Require this package in the composer.json of your Laravel project. This will download the package.
composer require casbin/laravel-authz
The Lauthz\LauthzServiceProvider is auto-discovered and registered by default, but if you want to register it yourself:
Add the ServiceProvider in config/app.php
'providers' => [
/*
* Package Service Providers...
*/
Lauthz\LauthzServiceProvider::class,
]The Enforcer facade is also auto-discovered, but if you want to add it manually:
Add the Facade in config/app.php
'aliases' => [
// ...
'Enforcer' => Lauthz\Facades\Enforcer::class,
]To publish the config, run the vendor publish command:
php artisan vendor:publish
This will create a new model config file named config/lauthz-rbac-model.conf and a new lauthz config file named config/lauthz.php.
To migrate the migrations, run the migrate command:
php artisan migrate
This will create a new table named rules
Once installed you can do stuff like this:
use Enforcer;
// adds permissions to a user
Enforcer::addPermissionForUser('eve', 'articles', 'read');
// adds a role for a user.
Enforcer::addRoleForUser('eve', 'writer');
// adds permissions to a role
Enforcer::addPolicy('writer', 'articles','edit');You can check if a user has a permission like this:
// to check if a user has permission
if (Enforcer::enforce("eve", "articles", "edit")) {
// permit eve to edit articles
} else {
// deny the request, show an error
}It provides a very rich api to facilitate various operations on the Policy:
Gets all roles:
Enforcer::getAllRoles(); // ['writer', 'reader']Gets all the authorization rules in the policy.:
Enforcer::getPolicy();Gets the roles that a user has.
Enforcer::getRolesForUser('eve'); // ['writer']Gets the users that has a role.
Enforcer::getUsersForRole('writer'); // ['eve']Determines whether a user has a role.
Enforcer::hasRoleForUser('eve', 'writer'); // true or falseAdds a role for a user.
Enforcer::addRoleForUser('eve', 'writer');Adds a permission for a user or role.
// to user
Enforcer::addPermissionForUser('eve', 'articles', 'read');
// to role
Enforcer::addPermissionForUser('writer', 'articles','edit');Deletes a role for a user.
Enforcer::deleteRoleForUser('eve', 'writer');Deletes all roles for a user.
Enforcer::deleteRolesForUser('eve');Deletes a role.
Enforcer::deleteRole('writer');Deletes a permission.
Enforcer::deletePermission('articles', 'read'); // returns false if the permission does not exist (aka not affected).Deletes a permission for a user or role.
Enforcer::deletePermissionForUser('eve', 'articles', 'read');Deletes permissions for a user or role.
// to user
Enforcer::deletePermissionsForUser('eve');
// to role
Enforcer::deletePermissionsForUser('writer');Gets permissions for a user or role.
Enforcer::getPermissionsForUser('eve'); // return arrayDetermines whether a user has a permission.
Enforcer::hasPermissionForUser('eve', 'articles', 'read'); // true or falseSee Casbin API for more APIs.
This package comes with EnforcerMiddleware, RequestMiddleware middlewares. You can add them inside your app/Http/Kernel.php file.
protected $routeMiddleware = [
// ...
// a basic Enforcer Middleware
'enforcer' => \Lauthz\Middlewares\EnforcerMiddleware::class,
// an HTTP Request Middleware
'http_request' => \Lauthz\Middlewares\RequestMiddleware::class,
];Then you can protect your routes using middleware rules:
Route::group(['middleware' => ['enforcer:articles,read']], function () {
// pass
});If you need to authorize a Request，you need to define the model configuration first in config/lauthz-rbac-model.conf:
[request_definition]
r = sub, obj, act
[policy_definition]
p = sub, obj, act
[role_definition]
g = _, _
[policy_effect]
e = some(where (p.eft == allow))
[matchers]
m = g(r.sub, p.sub) && keyMatch2(r.obj, p.obj) && regexMatch(r.act, p.act)Then, using middleware rules:
Route::group(['middleware' => ['http_request']], function () {
Route::resource('photo', 'PhotoController');
});If you need multiple permission controls in your project, you can configure multiple enforcers.
In the lauthz file, it should be like this:
return [
'default' => 'basic',
'basic' => [
'model' => [
// ...
],
'adapter' => Lauthz\Adapters\DatabaseAdapter::class,
// ...
],
'second' => [
'model' => [
// ...
],
'adapter' => Lauthz\Adapters\DatabaseAdapter::class,
// ...
],
];Then you can choose which enforcers to use.
Enforcer::guard('second')->enforce("eve", "articles", "edit");You can create a policy from a console with artisan commands.
To user:
php artisan policy:add eve,articles,readTo Role:
php artisan policy:add writer,articles,editAdds a role for a user:
php artisan role:assign eve writerAuthorization rules are cached to speed up performance. The default is off.
Sets your own cache configs in Laravel's config/lauthz.php.
'cache' => [
// changes whether Lauthz will cache the rules.
'enabled' => false,
// cache store
'store' => 'default',
// cache Key
'key' => 'rules',
// ttl \DateTimeInterface|\DateInterval|int|null
'ttl' => 24 * 60,
