本文實例講述了Laravel框架實現的rbac權限管理操作。分享給大家供大家參考，具體如下：
介紹：根據不同的權限，在菜單欄顯示不同的功能，只對菜單進行了限制，若對路由也進行限制，請自行完善
1、建表（用戶表、角色表、權限表、用戶角色表、角色權限表）
CREATE TABLE IF NOT EXISTS mr_role ( id int(11) PRIMARY KEY AUTO_INCREMENT COMMENT '自增id', name varchar(30) NOT NULL COMMENT '角色名' )ENGINE=innodb DEFAULT CHARSET=utf8 COMMENT='角色表'; CREATE TABLE IF NOT EXISTS mr_privilege ( id int(11) PRIMARY KEY AUTO_INCREMENT COMMENT '自增id', name varchar(30) NOT NULL COMMENT '權限名', route varchar(50) NOT NULL COMMENT '權限所有的路由', description varchar(100) NOT NULL COMMENT '權限的描述' )ENGINE=innodb DEFAULT CHARSET=utf8 COMMENT='權限表'; CREATE TABLE IF NOT EXISTS mr_user_role ( id int(11) PRIMARY KEY AUTO_INCREMENT COMMENT '自增id', user_id int(11) NOT NULL COMMENT '用戶id', role_id int(11) NOT NULL COMMENT '角色id' )ENGINE=innodb DEFAULT CHARSET=utf8 COMMENT='用戶角色表'; CREATE TABLE IF NOT EXISTS mr_role_privilege ( id int(11) PRIMARY KEY AUTO_INCREMENT COMMENT '自增id', role_id int(11) NOT NULL COMMENT '角色id', privilege_id int(11) NOT NULL COMMENT '權限id' )ENGINE=innodb DEFAULT CHARSET=utf8 COMMENT='角色權限表';
2、在用戶模型和角色模型中實現多對多
class User extends Model
{
protected $primaryKey = 'id';
protected $table = 'user';
public $timestamps = false;
public $guarded = [];
public function roles()
{
return $this->belongsToMany('App\Model\Role', 'user_role', 'user_id', 'role_id')->withPivot('user_id', 'role_id');
}
}
class Role extends Model
{
protected $table = 'role';
protected $primaryKey = 'id';
public $timestamps = false;
public $guarded = [];
public function privileges()
{
return $this->belongsToMany('App\Model\Privilege', 'role_privilege', 'role_id', 'privilege_id')->withPivot(['role_id', 'privilege_id']);
}
}
3、將菜單視為公共區域，在app\Providers\AppServiceProvider.php里寫
public function boot()
{
\View::composer('layout.slide', function($view) {
$roles_id = User::find(session('user')['id'])->roles->map(function ($role) {
return $role->id;
}); // 使用map，最終得到的結果$roles_id = [1, 2, ...]
$privileges = [];
foreach ($roles_id as $role) {
$privileges = array_merge($privileges, Role::find($role)->privileges->map(function ($privilege) {
return [$privilege->name, $privilege->route];
})->toArray());
} // 得到的結果，$prpvileges = [['index/..', '列表']， ['', '']]
$view->with('privileges', $privileges);
});
}
4、菜單的實現（可以直接遍歷一個div，我這里因為有不同的樣式，便用了判斷）
@foreach ($privileges as $privilege)
@if ($privilege[1] == 'key/index' && $privilege[0] == '鍵名列表')
<div class="slide__left__key" style="margin-top: 10px;"><a href="{{ url('key/index') }}" rel="external nofollow" ><span class="glyphicon glyphicon-th"></span> 鍵名列表</a></div>
@endif
@if ($privilege[1] == 'key/create' && $privilege[0] == '添加鍵名')
<div class="slide__left__key"><a href="{{ url('key/create') }}" rel="external nofollow" ><span class="glyphicon glyphicon-plus"></span> 添加鍵名</a></div>
@endif
@if ($privilege[1] == 'project/index' && $privilege[0] == '項目列表')
<div class="slide__left__key" style="margin-top: 20px;"><a href="{{ url('project/index') }}" rel="external nofollow" ><span class="glyphicon glyphicon-th-list"></span> 項目列表</a></div>
@endif
@if ($privilege[1] == 'project/create' && $privilege[0] == '添加項目')
<div class="slide__left__key"><a href="{{ url('project/create') }}" rel="external nofollow" ><span class="glyphicon glyphicon-edit"></span> 添加項目</a></div>
@endif
@if ($privilege[1] == 'user/index' && $privilege[0] == '用戶列表')
<div class="slide__left__key" style="margin-top: 20px;"><a href="{{ url('user/index') }}" rel="external nofollow" ><span class="glyphicon glyphicon-th-large"></span> 用戶列表</a></div>
@endif
@if ($privilege[1] == 'user/create' && $privilege[0] == '添加用戶')
<div class="slide__left__key"><a href="{{ url('user/create') }}" rel="external nofollow" ><span class="glyphicon glyphicon-plus-sign"></span> 添加用戶</a></div>
@endif
@endforeach
希望本文所述對大家基于Laravel框架的PHP程序設計有所幫助。
