OmniAuth::NoSessionError - 您必须提供会话才能使用 OmniAuth.(在设计中配置) [英] OmniAuth::NoSessionError - You must provide a session to use OmniAuth. (configured in devise)

问题描述

我正在学习如何使用 omniauth 作为 ember 应用程序的后端.

Hi I am learning how to use omniauth as backend for ember app.

当我运行我的应用程序时，我得到了下面提到的错误OmniAuth::NoSessionError - 您必须提供会话才能使用 OmniAuth

when i run my application I get the below mentioned erroe OmniAuth::NoSessionError - You must provide a session to use OmniAuth

在resue rails s我的应用程序停止在下面的行.

on resue rails s my applicataion halts at line below.

  172: def call!(env) # rubocop:disable CyclomaticComplexity
    173:   unless env['rack.session']
    174:     error = OmniAuth::NoSessionError.new('You must provide a session to use OmniAuth.')
 => 175:     fail(error)
    176:   end
    177:

推荐答案

这是因为你禁用了 session 中间件(查看 rake middleware 的输出).如果没有会话中间件，Omniauth 将无法工作.

It is because you disabled the session middleware (look at the output of rake middleware). Omniauth will not work without the session middleware.

您在此处禁用了它:Rails.application.config.session_store :disabled

如果您因为除了 Omniauth 之外不使用它而试图放弃会话，那么您唯一能做的就是编写自己的中间件，注入 ActionDispatch::Session::CookieStore 以及其他可能基于 URL 的必要中间件(即，如果 URL 是 /auth/*).这是我用来实现此目的的示例(仅当 URL 路径不是 /api/... 时才使用会话):

If you are trying to ditch session because you do not use it other than for Omniauth, then the only thing you can do is write your own middleware that injects ActionDispatch::Session::CookieStore and possibly other necessary middlewares based on the URL (i.e. if the URL is /auth/*). Here is an example of what I use to achieve this (only uses session if URL path is not /api/...):

# /config/application.rb
config.middleware.insert_before ActionDispatch::ParamsParser, "SelectiveStack"

# /config/initializers/omniauth.rb
::OmniAuthConfig = Proc.new do
  provider :github, # ...
end

# /app/middleware/selective_stack.rb
class SelectiveStack
  def initialize(app)
    @app = app
  end

  def call(env)
    if env["PATH_INFO"].start_with?("/api/") # <--- Change URL path here
      @app.call(env)
    else
      middleware_stack.build(@app).call(env)
    end
  end

private
  def middleware_stack
    @middleware_stack ||= begin
      ActionDispatch::MiddlewareStack.new.tap do |middleware|
        # needed for OmniAuth
        middleware.use ActionDispatch::Cookies
        middleware.use Rails.application.config.session_store, Rails.application.config.session_options
        middleware.use OmniAuth::Builder, &OmniAuthConfig
        # needed for Doorkeeper /oauth views
        middleware.use ActionDispatch::Flash
      end
    end
  end
end

在这个例子中，我只在 URL not 以 /api/ 开头时启用会话中间件.当然，您将仍然需要删除 Rails.application.config.session_store :disabled 并正确设置会话存储.在我的示例中，我使用了 cookie 存储.您可能需要根据 rake middleware 中缺少的中间件来调整我的示例.但是，如果您不是出于性能原因这样做，那么只需重新启用会话中间件即可.

In this example I only enable the session middleware when the URL does not start with /api/. You will still need to remove Rails.application.config.session_store :disabled and properly set up your session store, of course. In my example I use the cookie store. You might need to tweak my example based on which middleware you are missing in rake middleware. But if you're not doing this for performance reasons then just reenable the session middleware.
