Laravel用户策略始终拒绝授权

我在Laravel中创建了一个

UserPolicy

，并试图在控制器中使用

$this->authorize（User:：class）

，但是，当我访问

UserController@index

，如果删除

$this->authorize（用户：：类），则不会出现此问题

尝试传递用户实例而不是类名

$this->authorize（auth（）->user（））

？@linktoahef刚刚尝试传递，但用户在访问用户控制器的索引路由时登录时没有任何更改？尝试$this->authorize（'index'，user:：class））；在app/Providers/AuthServiceProvider.php中添加使用app\User；尝试传递用户实例而不是类名
