Cookie溢出与Twitter登录

Question

当我尝试在我的网站上使用twitter登录时,我发现了一些错误.

ActionDispatch::Cookies::CookieOverflow in Users::OmniauthCallbacksController#twitter 

ActionDispatch::Cookies::CookieOverflow

我找不到解决方案,这是我使用的代码.

omn​​iauth_callbacks_controller.rb

def twitter
@user = User.find_for_provider_oauth(request.env["omniauth.auth"], current_user)

if @user.persisted?
  sign_in_and_redirect @user, :event => :authentication
  set_flash_message(:notice, :success, :kind => "twitter") if is_navigational_format?
else
  session["devise.twitter_data"] = request.env["omniauth.auth"]
  redirect_to new_user_registration_url
end

devise.rb

require "omniauth-twitter"


config.omniauth :twitter, 'xxxxxxx', 'xxxxxxxxxxxk', :strategy_class => OmniAuth::Strategies::Twitter

user.rb

def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_initialize.tap do |user|
  user.provider = auth.provider
  user.uid = auth.uid
  user.name = auth.info.name
  user.oauth_token = auth.credentials.token
  user.oauth_expires_at = Time.at(auth.credentials.expires_at)
  user.save!
end

def self.find_for_provider_oauth(auth, signed_in_resource=nil)
user = User.where(:provider => auth.provider, :uid => auth.uid).first
unless user
  user = User.create(name:auth.extra.raw_info.name,
                     provider:auth.provider,
                     uid:auth.uid,
                     email:auth.info.email,
                     password:Devise.friendly_token[0,20],
                     invite_code:"42TXP"
                     )
end
user

Answer 1

使用: .except("extra")

session["devise.twitter_data"] = request.env["omniauth.auth"].except("extra")

它从中删除了很大一部分cookie,根本不需要.

Answer 2

这是你在save的else部分中放入会话的内容

session["devise.twitter_data"] = request.env["omniauth.auth"]

它对于一个cookie来说可能太大了.您应该将该信息保存在其他地方.或者不要保留它.
