security.yml导致InvalidArgumentException:"您必须至少添加一个身份验证提供程序"

Question

根据教程,我删除了内存提供程序和DemoBundle,并添加了数据库提供程序.但我得到InvalidArgumentException:"你必须至少添加一个身份验证提供程序".

我的security.yml:

# you can read more about security in the related section of the documentation
# http://symfony.com/doc/current/book/security.html
security:
    # http://symfony.com/doc/current/book/security.html#encoding-the-user-s-password
  encoders:
    AppBundle\Entity\User:
      algorithm: bcrypt

  # http://symfony.com/doc/current/book/security.html#hierarchical-roles
  role_hierarchy:
    ROLE_GLOBAL_MODERATOR: ROLE_USER
    ROLE_ADMIN: ROLE_GLOBAL_MODERATOR

  # http://symfony.com/doc/current/book/security.html#where-do-users-come-from-user-providers
  providers:
    db:
      entity:
        class: AppBundle:User
        property: email
        # if you're using multiple entity managers
        # manager_name: customer

  # the main part of the security, where you can set up firewalls
  # for specific sections of your app
  firewalls:
    # disables authentication for assets and the profiler, adapt it according to your needs
    dev:
      pattern:  ^/(_(profiler|wdt)|css|images|js)/
      security: false
    default:
      pattern: ^/
      security: false

  # with these settings you can restrict or allow access for different parts
  # of your application based on roles, ip, host or methods
  # http://symfony.com/doc/current/cookbook/security/access_control.html
  access_control:
      #- { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY, requires_channel: https }

我也试过使用YAML可视化器,以确保我没有搞砸缩进,这是正确的.

这是因为您还没有配置身份验证提供程序.我的意思是防火墙下的密钥.身份验证提供程序是匿名的,form_login,http_basic等.对于配置提供程序的模式并不重要,但必须至少配置其中一个.

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