use Illuminate\Support\Facades\Cache;

class NameAndRole
{
    public $username;
    public $role;

    public function __construct() {
        $user = \Auth::user();
        $this->username = $user->name;

        $role = ;    //怎么获得当前登录用户的角色?
    }
}</code>

在你的users模型以及roles模型里,应该有像下边这样的方法:

<code>class User extends Model
{
    //...
    
    public function roles ()
    {
        // 多对多的关系(一个用户有多个角色)
        return $this->belongsToMany(\App\Role::class); 
    }
    
    //...
}

class Role extends Model
{
    //...
    
    public function users ()
    {
        // 多对多的关系(一个角色赋予了多个用户)
        return $this->belongsToMany(\App\User::class);
    }
    
    //...
}</code>
Copy after login

模型里边有了以上方法,获取角色就像下边这样(访问动态属性):

<code>$roles = $user->roles; // 一个用户可能有多个角色</code>
Copy after login
