symfony - 将 FOSUserBundle 与 Symfony 3.3 一起使用时出现 YAML 错误

Question

在 Symfony 中设置 FOSUserBundle 时，我遇到了一个奇怪的错误。 我收到此错误消息:

A colon cannot be used in an unquoted mapping value at line 30 (near " csrf_token_generator: security.csrf.token_manager").

这是我的 security.yml，谁能告诉我我做错了什么？

# To get started with security, check out the documentation:
# https://symfony.com/doc/current/security.html
security:
    encoders:
        FOS\UserBundle\Model\UserInterface: bcrypt

role_hierarchy:
    ROLE_ADMIN:       ROLE_USER
    ROLE_SUPER_ADMIN: ROLE_ADMIN
# https://symfony.com/doc/current/security.html#b-configuring-how-users-are-loaded
providers:
#        in_memory:
#            memory: ~
    fos_userbundle:
        id: fos_user.user_provider.username

firewalls:
    main:
        pattern: ^/
            form_login:
                provider: fos_userbundle
                csrf_token_generator: security.csrf.token_manager

            logout:       true
            anonymous:    true
    # disables authentication for assets and the profiler, adapt it according to your needs
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false

access_control:
    - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/admin/, role: ROLE_ADMIN }

我已尝试注释掉错误消息 (csrf_token_generator) 中提到的行，但错误仍然存​​在，现在指向其上方的行。

我认为这是缩进的问题，

尝试改变这一点:

pattern: ^/
    form_login:
         provider: fos_userbundle
         csrf_token_generator: security.csrf.token_manager

    logout:       true
    anonymous:    true

对此:

pattern: ^/
form_login:
    provider: fos_userbundle
    csrf_token_generator: security.csrf.token_manager

logout:       true
anonymous:    true
