Question

我收到以下错误，代码如下：

ServiceNotFoundException: The service "security.firewall.map.context.main" has a dependency on a non-existent service "security.user.provider.concrete.fos_user_bundle".

这是在我添加chain_provider:提供程序后发生的，如果我将其删除，它就可以正常运行。知道为什么吗？

security: 
    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER
        ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]

    providers:
        fos_userbundle:
            id: fos_user.user_provider.username_email
        my_fos_facebook_provider:
            id: my.facebook.user
        chain_provider:
            chain:
                providers: [fos_user_bundle, my_fos_facebook_provider]
        in_memory:
            memory:
                users:
                    user:  { password: userpass, roles: [ 'ROLE_USER' ] }
                    admin: { password: adminpass, roles: [ 'ROLE_ADMIN' ] }

            security: false

Answer 1

这是FOSFacebookBundle文档中的一个错误。您必须使用fos_userbundle和NOT fos_user_bundle（注意下划线）作为提供者名称。

Answer 2

你添加'my_fos_facebook_provider'了吗？你必须将它绑定到'my.facebook.user service'（最后2行）：

    providers:
        chainprovider:
            chain:
                providers: [fos_userbundle, my_fos_facebook_provider]
    fos_userbundle:
        id: fos_user.user_provider.username
    my_fos_facebook_provider:
        id: my.facebook.user

symfony中的provider和chain_provider问题
