Symfony2:使用两个不同的用户提供程序登录网站时无法模拟用户
在我的网站中，用户可以使用简单帐户(在我的网站中创建，配置为MY_OWN_USER提供程序，通过电子邮件选择用户)登录，也可以使用Facebook登录(通过fosfacebook捆绑包集成)登录.
In my website user can log-in with simple account (created in my website, configured MY_OWN_USER provider, which selects user by email) or using facebook log-in (integrated through fosfacebook bundle).
当我尝试模拟用户时(附加链接'...?_ switch_user=demo@demo.com'，如
When i'm trying to impersonate user (appending link '...?_switch_user=demo@demo.com', like described in Symfony2 documentation) Symfony2 logs such warning:
安全性.警告:切换用户失败:用户未在Facebook上通过身份验证"
我检查了 Symfony \ Component \ Security \ Http \ Firewall \ SwitchUserListener ，看起来默认情况下它不是MY_OWN_USER提供程序，而是fosfacebook提供程序，它试图通过facebook_id选择用户(如果我附加链接)与'...?_ switch_user = FACEBOOK_ID'-切换用户正常工作！)
I've checked Symfony\Component\Security\Http\Firewall\SwitchUserListener and looks like by default it gets not MY_OWN_USER provider but fosfacebook provider which tries to select user by facebook_id (if i append link with '...?_switch_user=FACEBOOK_ID' - switch user works correctly!)
那么如何使SwitchUserListener能够获得MY_OWN_USER提供程序，该提供程序通过电子邮件而不是通过Facebook ID选择用户?
So how to make that SwitchUserListener would get MY_OWN_USER provider which selects user by email not by facebook id?
在security.yml中的防火墙配置中配置模拟时，可以指定应使用哪个提供程序来查找被模拟的用户(参考).例如:
When configuring impersonation in your firewall config in security.yml, you can specify which provider should be used to find the user who is being impersonated (ref). For example:
switch_user:
provider: MY_OWN_USER
希望这会有所帮助！
