AuthenticationCredentialsNotFoundException:安全上下文不包含身份验证令牌

我得到以下错误

AuthenticationCredentialsNotFoundException：安全上下文不包含身份验证令牌。一个可能的原因可能是没有为此URL配置防火墙。

我已经尝试了解决方案，因为我知道当没有为路由配置安全防火墙时会发生这个错误，但我似乎无法解决这个错误。

这是我的安全。yml

    # strategy can be: affirmative, unanimous or consensus
    strategy: unanimous
  encoders:
    "MyName'MyBundle'Entity'User": { algorithm: sha1, encode_as_base64: false, iterations: 0 }   # You'll set this to sha1 when you have everything working.

    default:    
      entity: { class: MyName'MyBundle'Entity'User, property: username } # This is an ORM entity and username is just the username property of the entity.

      logout:

    - { path: ^/members, roles: ROLE_MEMBER }
    - { path: ^/shop/ipn/paypal, roles: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/shop/step, roles: IS_AUTHENTICATED_FULLY }

    - { path: ^/application, roles: IS_AUTHENTICATED_FULLY }
    - { path: ^/account, roles: IS_AUTHENTICATED_FULLY }
    - { path: ^/login, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/home, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/, roles: IS_AUTHENTICATED_ANONYMOUSLY }
    #- { path: ^/foo, access: "hasRole('FOO') and hasRole('BAR')" }
    #- { path: ^/forum, access: "!hasRole('ROLE_BANNED')"}

因此，我添加了默认路由和允许匿名，但错误仍然存在
