将随机url参数传递给OmniAuth [英] Passing random url params to OmniAuth

问题描述

这里有一个链接示例： / accounts / auth / facebook？do_something_after_return = 1
现在我想能够在回调中检索这个 do_something_after_return 。我不在乎是否保存在会话或其他地方。问题是，我不知道我可以在哪里拦截这个参数。

什么是控制器和链接 / accounts / auth / facebook 指向？
路线告诉我什么，这根本就不在。我所有的路线是这个 / accounts / auth /：provider（。：format {：controller =>accounts / omniauth_callbacks，：action =>passthru} 这是一个回调。

解决方案

参数被捕获在 env [omniauth.params ] 。

I'm using omniauth with devise and I'm wondering how to pass url params and access them.

Here's a link example: /accounts/auth/facebook?do_something_after_return=1 Now I want to be able to retrieve this do_something_after_return in the callback. I don't care if it's saved in session or elsewhere. Problem is, I don't know where can I intercept this param.

What is the controller and the action that link /accounts/auth/facebook points to? Routes tell me nothing, it's simply not there. All I have in the routes is this /accounts/auth/:provider(.:format {:controller=>"accounts/omniauth_callbacks", :action=>"passthru"} which is a callback.

解决方案

Params are captured in env["omniauth.params"].
