通过OmniAuth传递参数 [英] Passing parameters through OmniAuth

问题描述

我需要将一些参数传递给回调操作.从源代码来看，OmniAuth应该将查询字符串添加到回调URL，但奇怪的是没有.当我打开

I need to pass some parameters to callback action. Judging from the source code, OmniAuth should add query string to callback URL but strangely it does not. When I open

/auth/facebook?from=partner

...然后重定向到Facebook，return_url就是

...and get redirected to Facebook, return_url is just

/auth/facebook/callback

...没有任何参数.

...without any parameters.

推荐答案

在解决了所有上述问题之后，我想出了关于 Facebook 的处理方法，默认情况下，该工具不会在 Facebook 中显示参数request.env["omniauth.auth"].

After struggling with all the above answers, I figured out what to do regarding Facebook, which by default does not display the params in request.env["omniauth.auth"].

所以-如果您在查询中使用查询字符串，则类似于以下内容:

So -- If you are using a query string for the callback, similar to something like this:

"/auth/facebook?website_id=#{@website.id}"

获取该website_id参数的唯一方法是使用request.env["omniauth.params"]. 注意:请确保您使用的是omniauth.params而不是omniauth.auth －这使我绊了一会儿.

The only way to get that website_id param is by using request.env["omniauth.params"]. NOTE: MAKE SURE YOU USE omniauth.params and not omniauth.auth -- this one tripped me up for a while.

然后，要进行测试，可以在控制器动作中进行检查(请注意RAISE行...):

Then, to test this out, you can inspect it within your controller action (notice the RAISE line...):

def create
  raise request.env["omniauth.params"].to_yaml 
  # the rest of your create action code...
end

您应该在那里看到您的参数.伟大的.现在，回到您的控制器并删除该RAISE行.然后，您可以在控制器操作中按以下方式访问参数:

You should see your parameter there. Great. Now, go back to your controller and remove that RAISE line. Then, you can access the param as follows in your controller action:

params = request.env["omniauth.params"]
website_id = params["website_id"]

注意:在params ["website_id"]中，您需要使用引号而不是符号.

NOTE: in params["website_id"] you need to use quotes and NOT a symbol.
