Devise + Omniauth - 如何传递额外的参数? [英] Devise + Omniauth - How to pass extra parameters along?

问题描述

我可以在应用程序中加载/users/auth/facebook 以连接到 facebook.我希望能够知道请求来自哪里.无论是来自注册 facebook 的用户，还是只想与 facebook 联系的现有用户.根据类型，反应非常不同.

I have the ability in the app to load /users/auth/facebook to connect to facebook. I want to be able to know where the request came from. Whether it was from a user who is registering with facebook, or a existing user who simply wants to connect with facebook. Based on the type, the responses are very different.

如何在认证时将参数传递给 omniauth.我试着做:

How can I pass a param along to omniauth when authenticating. I tried doing:

/users/auth/facebook?connect_action=signup_connect_to_facebook

但是当它点击 AuthenticationsController#Create 时，connect_action 参数没有成功

But that connect_action param didn't make it when it hit AuthenticationsController#Create

想法?谢谢

推荐答案

你必须使用 :params 选项，如

You have to use the :params options, as in

omniauth_authorize_path(:user, :facebook, var: 'value', var2: 'value2' )

稍后在回调中，您可以访问 request.env['omniauth.params'] 以获取哈希值！:)

and later in the callback you can access request.env['omniauth.params'] to get the hash! :)
