Ruby on rails 轨道4+；Omniauth+；设计：注销链接不工作

我使用Omniauth作为登录Rails应用程序的唯一方法

问题是：当用户单击“注销”时，页面会重新加载，并且注销链接仍然存在（尽管用户是否已登录？逻辑将其包装）。这让我相信用户并没有真正注销

这是我的index.html.erb：

<% if user_signed_in? %>
  <%= link_to "Authenticate with Google", user_omniauth_authorize_path(:google_oauth2) %>
<% else %>
  <%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
<% end %>

class OmniauthCallbacksController < Devise::OmniauthCallbacksController 
  skip_before_filter :redirect_to_login_if_required
  def google_oauth2
    @user = User.from_omniauth(request.env["omniauth.auth"])
    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication
      return
    else
      session["devise.user_attributes"] = @user.attributes
      redirect_to new_user_registration_path
    end
  end
end

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

以及我的omniauth\u回调\u controller.rb：

<% if user_signed_in? %>
  <%= link_to "Authenticate with Google", user_omniauth_authorize_path(:google_oauth2) %>
<% else %>
  <%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
<% end %>

class OmniauthCallbacksController < Devise::OmniauthCallbacksController 
  skip_before_filter :redirect_to_login_if_required
  def google_oauth2
    @user = User.from_omniauth(request.env["omniauth.auth"])
    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication
      return
    else
      session["devise.user_attributes"] = @user.attributes
      redirect_to new_user_registration_path
    end
  end
end

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

不幸的是，这并没有给我带来一个错误。它只是刷新索引页面，就好像什么都没发生一样

编辑：这是我单击注销时的帖子

编辑2：我已将其包含在我的应用程序\u controller.rb中

def self.from_omniauth(auth)
  if user = User.find_by_email(auth.info.email)
    user.provider = auth.provider
    user.uid = auth.uid
    user
  else
    where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
      user.provider = auth.provider
      user.uid = auth.uid
      user.email = auth.info.email # THIS (user.email) value i want to provide to my registration form as default value
   end
  end
end

before_action :authenticate_user!

现在我在控制台中得到的错误消息是：

我建议将if切换为除非，这样在用户登录时会显示注销链接

<% unless user_signed_in? %>
  <%= link_to "Authenticate with Google", user_omniauth_authorize_path(:google_oauth2) %>
<% else %>
  <%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
<% end %>

：删除）%%>

使用Desive时，显示校正链接的另一种方式是：

<%unless current_user.blank? -%>
  <%= link_to "Authenticate with Google", user_omniauth_authorize_path(:google_oauth2) %>
<%else -%>
  <%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
<%end-%>

：删除）%%>

从您发布的日志中，您已经

筛选器链暂停为：验证\u已签名\u已退出\u已呈现或重定向用户

这就是你问题的原因

在过滤器之前添加

skip\u:verify\u signed\u out\u user

到控制器应该可以解决问题

更新：

您需要将index.html.erb中的代码更改为以下内容

<% if user_signed_in? %>
  <%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
<% else %>
  <%= link_to "Authenticate with Google", user_omniauth_authorize_path(:google_oauth2) %>
<% end %>

：删除）%%>

请使用

/config/initializers/develope.rb更新您的帖子

jquery ujs是否正确加载并工作？否则，链接的

部分（必需）将无法工作。尝试检查web检查器/服务器日志，查看是否确实发送了删除调用。您是否在/config/initializers/designe.rb中注释了这一行

config.sign\u out\u via=：DELETE

？如果是这样，请取消对它的注释并检查.Nope-config.sign\u out\u via=：delete在其中。您可以发布在单击注销时生成的日志吗？即使在我进行了身份验证之后，这仍然会一直为我提供“使用谷歌进行身份验证”。您100%确定登录正常吗？您介意发布编辑帖子以包含日志吗？在2015-07-06 11:00:22-0400时开始删除“/users/sign_out”for：：1，由designe：：sessioncontroller处理#销毁为HTML参数：{“authenticity_token”=>“7QXScU8eVW6NVedKG5P86rPxkaP8uJdUzyJ712ZrYXtK7QjP/m33eQ2WE/ituwfq2geenxlivibxejh6w=”}重定向到筛选器链暂停为：验证\u注销\u用户呈现或重定向完成302在1ms内找到（ActiveRecord:0.0ms）@beaconhill-如果您指的是“通过谷歌验证”始终显示上述代码，用户似乎没有登录，因此注销功能无法工作。但当我在Admin中查看用户记录时，“当前登录时间”时间戳是我单击login的时间和“登录计数”增加…我将其添加到omniauth\u callbacks\u controller.rb中，但我仍在暂停筛选器链，原因是：验证\u已签名\u用户已呈现或重定向。这是当前的情况：在\u筛选器之前跳过\u：如果需要，将\u重定向到\u登录\u，：验证\u已注销_user@beaconhill我想你应该把它添加到

我没有users\u controller.rb。我通过Desive生成了用户模型。@beaconhill很抱歉，您应该将其添加到
