异常TokenBlacklistedException 不起作用

我正在使用 Laravel 8，我正在尝试使用 Exception: TokenBlacklistedException 和 TokenExpiredException 但它不起作用。返回以下错误：

【解决方案1】：

您可以在catch 块中使用instanceof。 instanceof用于判断PHP变量是否为某个类的实例化对象：

try 
{
    // 
} 
catch (Exception $e)
{
    if ($e instanceof TokenBlacklistedException)
    {
        //
    } 
    elseif ($e instanceof TokenExpiredException)
    {
        //
    }
    elseif ($e instanceof TokenInvalidException)
    {
        //
    }
    ...
}

无论如何，在 Laravel 中，所有异常都由 App\Exceptions\Handler 类处理。 Previous versions also said你可以在app/Exceptions/Handler.php处理异常。
