Question

我在尝试

时遇到了这个问题

php app/console server:run

它告诉我这个错误：

无法识别 "security.providers.in_memory.memory" 下的选项 "admin"

这是我的 security.yml

security:

        Symfony\Component\Security\Core\User\User: plaintext
        Custom\CMSBundle\Entity\User: bcrypt
    role_hierarchy:

    providers:
        chain_providers:
            chain:
                providers: [in_memory, user_db]
        in_memory:
            memory:
                users:
                admin: { password: adminpass, roles: ROLE_ADMIN }
        user_db:
            entity: { class: CustomCMSBundle:User, property: username }
    firewalls:
        main:

                target: /
            security: true
            anonymous: true
    access_control:
            - { path: /login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
            - { path: /cms/user, roles: ROLE_ADMIN }
            - { path: /.*, roles: IS_AUTHENTICATED_ANONYMOUSLY }

定义的用户（在本例中为 admin）应在 users 映射内定义，因此缩进必须大于 users:

in_memory:
    memory:
        users:
            admin: { password: adminpass, roles: ROLE_ADMIN }
