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 }

我已经尝试评论错误消息(csrf_token_generator)中提到的行,但错误仍然存​​在,现在指向它上面的行.

我认为这是一个缩进的问题,

试着改变这个:

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
