Question

我正在使用'omniauth-google-oauth2'登录谷歌并仔细阅读此处的所有说明

   https://github.com/plataformatec/devise/wiki/OmniAuth%3A-Overview

但我上面有错误。

我的路线

    devise_for :users, :controllers => {
      :omniauth_callbacks => "users/omniauth_callbacks"

    }

devise.rb代码

  config.omniauth :google_oauth2, "863625299460- 420n6c7lvad91dfvko60uamtvtr6huhf.apps.googleusercontent.com", "dcvA2aZRZi27KCQjWTYP30pw", {  access_type: "offline", approval_prompt: "" }

omniauth回调控制器代码

     def google_oauth2
       #@user = User.find_for_google_oauth2(request.env["omniauth.auth"], current_user)
       binding.pry #control not coming here
     end

回调后我有错误。看截图

Answer 1

这看起来像路线问题。如果你做“rake routes | grep auth”，你看到了什么？

Answer 2

我遇到的问题完全相同。确保在config / initializers / deviser.rb中需要omniauth-google-oauth2 gem

# ==> OmniAuth
# Add a new OmniAuth provider. Check the wiki for more information on setting
# up on your models and hooks.
require "omniauth-google-oauth2"
config.omniauth :google_oauth2, ENV["GOOGLE_KEY"], ENV["GOOGLE_SECRET"],
                                { access_type: "offline", approval_prompt: "force" }

我添加了devise.rb文件的全部内容以提供上下文。

无法为Users :: OmniauthCallbacksController找到操作'google_oauth2'
