> User增加HasRole Traits

<?php
    
    namespace App;
    
    use Illuminate\Notifications\Notifiable;
    use Illuminate\Foundation\Auth\User as Authenticatable;
    use  Spatie\Permission\Traits\HasRoles;

### 安装html生成器laravelcollective/html ###

[https://packagist.org/packages/laravelcollective/html][https_packagist.org_packages_laravelcollective_html]

composer require laravelcollective/html

[https://laravelcollective.com/docs/master/html][https_laravelcollective.com_docs_master_html]

> config/app.php:

'providers' => [
        // ...
        Collective\Html\HtmlServiceProvider::class,
        // ...
      ],
    'aliases' => [
        // ...
          'Form' => Collective\Html\FormFacade::class,
          'Html' => Collective\Html\HtmlFacade::class,
        // ...
      ],

### 基本使用 ###

> 路由

Route::get('/', ['uses'=>'UserController@index']);
    Route::get('/getp/{user}', ['uses'=>'UserController@getPermission']);//取得是否有这个权限规则

> 控制器

<?php
    
    namespace App\Http\Controllers;
    
    use App\User;
    use Illuminate\Http\Request;
    use Spatie\Permission\Models\Role;
    use Spatie\Permission\Models\Permission;
    
    class UserController extends Controller
    {
        //
        public function index(){
          $role = Role::create(['name' => 'writer']);
          $permission = Permission::create(['name' => 'edit articles']);
        }
        public function getPermission(User $user){
          print_r($user->toArray());
          $permissions = $user->permissions;
          print_r($permissions);
        }
    }

> 测试  
> 浏览器打开

http://192.168.91.130:86
    //取得权限
    http://192.168.91.130:86/getp/1

这个生成SQL语句如下

> getPermission

select `permissions`.*, 
    `model_has_permissions`.`model_id` as `pivot_model_id`, 
    `model_has_permissions`.`permission_id` as `pivot_permission_id`, 
    `model_has_permissions`.`model_type` as `pivot_model_type`
     from `permissions` inner join `model_has_permissions`
     on `permissions`.`id` = `model_has_permissions`.`permission_id` 
    where `model_has_permissions`.`model_id` = '1'
     and `model_has_permissions`.`model_type` = 'App\User'

这个就是多态关联的应用

> //获取所有//获取所有

$user->roles()

sql

select `roles`.*, 
    `model_has_roles`.`model_id` as `pivot_model_id`, 
    `model_has_roles`.`role_id` as `pivot_role_id`, 
    `model_has_roles`.`model_type` as `pivot_model_type`  
    from `roles` inner join `model_has_roles`  
    on `roles`.`id` = `model_has_roles`.`role_id` 
    where `model_has_roles`.`model_id` = '1'  
    and `model_has_roles`.`model_type` = 'App\User'

> 获取用户角色名称

$user->roles()->pluck('name')

Sql

select `name` from `roles` inner join `model_has_roles`  
    on `roles`.`id` = `model_has_roles`.`role_id`  
    where `model_has_roles`.`model_id` = '1'  
    and `model_has_roles`.`model_type` = 'App\User'

### Blade ###

@role('writer')
        I'm a writer!
    @else
        I'm not a writer...
    @endrole
    
    @hasrole('writer')
        I'm a writer!
    @else
        I'm not a writer...
    @endhasrole
    
    @hasanyrole(Role::all())
       任意一个这个角色
    @else
        I have none of these roles...
    @endhasanyrole
    
    @hasallroles(Role::all())
      所有这些角色
    @else
        I don't have all of these roles...
    @endhasallroles

> @can 指令验证用户是否拥有给定权限：

@can('Edit Post')
        I have permission to edit
    @endcan

User模型增加密码加密

public function setPasswordAttribute($password) {
          $this->attributes['password'] = bcrypt($password);
        }
