发生OmniAuth :: Strategies :: OAuth2 :: CallbackError

Question

我正在从事Rails项目，但是omniauth-linkedin-oauth2无法正常工作！我有如下错误。

   Authentication failure! csrf_detected: OmniAuth::Strategies::OAuth2::CallbackError, csrf_detected | CSRF detected

apps / controllers / omniauth_controller.rb

    class OmniauthCallbacksController < Devise::OmniauthCallbacksController
        def facebook
            @user = User.from_omniauth(request.env["omniauth.auth"].except("extra"))

            if @user.persisted?
                sign_in_and_redirect @user, event: :authentication
            else
                session["devise.user_attributes"] = @user.attributes
                redirect_to new_user_registration_url
            end
        end

        def linkedin
            @user = User.from_omniauth(request.env["omniauth.auth"].except("extra"))

            if @user.persisted?
                sign_in_and_redirect @user, event: :authentication
            else
                session["devise.user_attributes"] = @user.attributes
                redirect_to new_user_registration_url
            end
        end
    end
