Laravel中的permission权限管理的扩展包

1. 安装扩展包

composer require "spatie/laravel-permission:~2.7"

生成数据库迁移文件：

php artisan vendor:publish –provider=”Spatie/Permission/PermissionServiceProvider” –tag=”migrations”

在 migration 目录下可看到相关表信息，执行数据库迁移

php artisan migrate

生成配置信息：

php artisan vendor:publish --provider="Spatie/Permission/PermissionServiceProvider" --tag="config"

在 User 模型下加载

..... use Spatie/Permission/Traits/HasRoles;  // use  class User extends Authenticatable {      use HasRoles;  // 加载角色相关信息     .....

创建角色 和用户

use Spatie/Permission/Models/Role; use Spatie/Permission/Models/Permission;  ..... $role = Role::create(['name' => 'writer']);  // 创建角色 $permission = Permission::create(['name' => 'edit articles']);// 创建权限

使用

为用户添加权限

$user->givePermissionTo('edit articles');

为用户添加角色

$user->assignRole('writer');  $user->assignRole(['writer', 'admin']);

给用户删除权限

$user->revokePermissionTo('edit articles');

给角色添加权限

$role->givePermissionTo('edit articles');

为角色添加权限

$role->givePermissionTo('edit articles');

撤销一个权限 并且 添加一个新权限

$user->syncPermissions(['edit articles', 'delete articles']);

获得当前用户的角色集合

$user->getRoleNames();

将多个角色同步到权限

$role->syncPermissions($permissions); //  @param array $permissions  $permission->syncRoles($roles);

从角色中删除权限

$role->revokePermissionTo($permission); $permission->removeRole($role);

获取当前的用户的权限列表

$permissions = $user->permissions;

获取用户的所有权限，或者直接权限 （odel_has_permissions），或者从角色获取，或者从两者获取

$permissions = $user->getDirectPermissions(); $permissions = $user->getPermissionsViaRoles(); $permissions = $user->getAllPermissions();

获取用户的角色集合 collection

$roles = $user->getRoleNames(); // Returns a collection

返回指定角色的用户 | Returns only users with the role ‘writer’

$users = User::role('writer')->get(); //

返回指定权限的用户

$users = User::permission('edit articles')->get();

用户有什么角色

$user->hasRole('writer');

验证类

检查是否有某个权限

$user->hasPermissionTo('edit articles');  $user->can('edit articles');

检查是否有某个角色 | 或者列

$user->hasRole('writer');  $user->hasAnyRole(Role::all());  $user->hasAllRoles(Role::all());

传递 id 值进行判断是否有某个权限

$user->hasPermissionTo('1'); $user->hasPermissionTo(Permission::find(1)->id); $user->hasPermissionTo($somePermission->id);

是否拥有一组权限

$user->hasAnyPermission(['edit articles', 'publish articles', 'unpublish articles']);

检查一个角色是否有某些权限 | 删除某些权限

$role->hasPermissionTo('edit articles');   $role->revokePermissionTo('edit articles'); // 删除

模板使用

@role('writer')     I am a writer! @else     I am not a writer... @endrole  ------------------------  @hasrole('writer')     I am a writer! @else     I am not a writer... @endhasrole  ------------------------  @can('edit articles') // 拥有某个权限 可执行操作 // @endcan

数据填充

use Illuminate/Database/Seeder; use Spatie/Permission/Models/Role; use Spatie/Permission/Models/Permission;  class RolesAndPermissionsSeeder extends Seeder {     public function run()     {         // Reset cached roles and permissions         app()['cache']->forget('spatie.permission.cache');          // create permissions         Permission::create(['name' => 'edit articles']);         Permission::create(['name' => 'delete articles']);         Permission::create(['name' => 'publish articles']);         Permission::create(['name' => 'unpublish articles']);          // create roles and assign created permissions          $role = Role::create(['name' => 'writer']);         $role->givePermissionTo('edit articles');          $role = Role::create(['name' => 'moderator']);         $role->givePermissionTo(['publish articles', 'unpublish articles']);          $role = Role::create(['name' => 'super-admin']);         $role->givePermissionTo(Permission::all());     } }

提示：如果在数据库权限相关信息表的修改，必须掉用清除 缓存的方法

// 命令删除 php artisan cache:forget spatie.permission.cache    app()['cache']->forget('spatie.permission.cache');
