按照docs我實現了身份驗證。這裏是我的application_controller.rb
OmniAuthGoogleOAuth2在Rails 4中成功登錄後重定向到原始請求url
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
helper_method :current_user
before_action :auth_user
def current_user
@current_user ||= User.find(session[:user_id]) if session[:user_id]
end
private
def auth_user
current_user
if @current_user.nil?
flash[:notice] = "You need to be logged in to access this part of the site"
redirect_to root_path(url: request.url)
end
end
end
,我使用這個 「登錄」 鏈接
<%= link_to "Sign in with Google", "/auth/google_oauth2?url=#{@url}", id: "sign_in" %>
路線:get 'auth/:provider/callback', to: 'user_sessions#create'
控制器:
class UserSessionsController < ApplicationController
skip_before_filter :auth_user
def create
url = params[:url]
auth = env["omniauth.auth"]
if auth
user = User.from_omniauth(auth)
session[:user_id] = user.id
flash[:notice] = "Login Sucessful!"
redirect_to url
else
flash[:notice] = "error"
redirect_to root_path
end
end
def destroy
session[:user_id] = nil
redirect_to root_path
end
end
現在,當我沒有一個有效的會話嘗試去localhost:3000/privileged
我被重定向到th Ë根URL和登錄鏈接是這樣的:
http://localhost:3000/auth/google_oauth2?url=http://localhost:3000/privileged
然而,當我點擊它,我得到一個成功登錄,但隨後的錯誤,我不能重定向到零。爲什麼參數下降?或者是否有更好的方式將用戶重定向到通常成功登錄後最初請求的URL?
