任氏有无轩访问记录的登录

今天继续给任氏有无轩加功能。这次是对log页面进行了限制，需要进行HTTP一般登录才能访问。

在SF2中，是通过修改app/config/security.yml来完成的，由于我只是进行HTTP验证，并且也不复杂，所以这个文件也很简单：

security:
    encoders:
        SymfonyComponentSecurityCoreUserUser: plaintext
    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER
        ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]
    providers:
        in_memory:
            memory:
                users:
                    admin: { password: 123456, roles: [ 'ROLE_ADMIN' ] }
    firewalls:
        #dev:
        #    pattern:  ^/(_(profiler|wdt)|css|images|js)/
        #    security: false
        #login:
        #    pattern:  ^/demo/secured/login$
        #    security: false
        secured_area:
            #pattern:    ^/demo/secured/
            #form_login:
            #    check_path: /demo/secured/login_check
            #    login_path: /demo/secured/login
            #logout:
            #    path:   /demo/secured/logout
            #    target: /demo/
            pattern: ^/
            anonymous: ~
            http_basic:
              realm: Log
            #anonymous: ~
            #http_basic:
            #    realm: Secured Demo Area
    access_control:
        #- { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY, requires_channel: https }
        #- { path: ^/_internal/secure, roles: IS_AUTHENTICATED_ANONYMOUSLY, ip: 127.0.0.1 }
      - {path: ^/log, roles: ROLE_ADMIN}

至此，这个登录功能就算完成了。
