在 symfony 4.4 中支持类在 UserProvider 中不起作用

  • 772

升级到symfony 4.4后，发现网站上的授权被破坏了。当我尝试登录时，出现错误：

There is no user provider for user "App\Security\UserIdentity". Shouldn't the "supportsClass()" method of your user provider return true for this classname?

UserProvider 类中的 supportsClass() 方法如下所示：

namespace App\Security;

use App\ReadModel\User\AuthView;
use App\ReadModel\User\UserFetcher;
use Symfony\Component\Security\Core\Exception\UnsupportedUserException;
use Symfony\Component\Security\Core\Exception\UsernameNotFoundException;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Core\User\UserProviderInterface;

class UserProvider implements UserProviderInterface
{
...
    public function supportsClass($class): bool
    {
        dump($class);
        return $class instanceof UserIdentity;
        //return true;
    }

使用转储函数，我在探查器中看到 $class 参数如下所示：

"App\Security\UserIdentity"

告诉我，错在哪里？

    尝试与绝对类名进行比较：

    public function supportsClass($class): bool
{
    return $class === UserIdentity::class;
}
