Question

我正在尝试设置omniauth与facebook签名，这是我的设置：

路线：

devise_for :users, :controllers => { :omniauth_callbacks => "callbacks" }

app / controllers / callbacks_controller.rb中的

def facebook
    # You need to implement the method below in your model (e.g. app/models/user.rb)
    @user = User.from_omniauth(request.env["omniauth.auth"])

    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
      set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
    else
      session["devise.facebook_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end

  def failure
    redirect_to root_path
  end

在config/initializers/omniauth.rb

  Rails.application.config.middleware.use OmniAuth::Builder do
    provider :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET'],
             scope: 'email,user_birthday', display: 'popup'
  end

如果我点击链接：/users/auth/facebook/（因为我已经登录到facebook帐户，并且已经有一个用户在数据库中使用电子邮件，就像在facebook中使用的电子邮件一样）

这是发生的网络调用：

http://mywebapp.com/users/auth/facebook/

https://www.facebook.com/dialog/oauth?client_id=xxxxxx&display=popup&redirect_uri=http%3A%2F%2Fmywebapp.com%2Fusers%2Fauth%2Ffacebook%2Fcallback&response_type=code&scope=email%2Cuser_birthday&state=xxxxxx

http://mywebapp.com/users/auth/facebook/callback?code=xxxxxx-xxxxxx-xxxxxx-8phIgyflA_NgL-9-FTkXxwUv-xxxxxx-xxxxxx&state=xxxxxx

然后，浏览器中的最终网址为：

http://mywebapp.com/en#_=_

没有登录，也没有任何Flash消息。

那么，我该如何调试用户为什么不登录？

调用回调后为什么不登录？
