Alm*_*ron 10 authentication devise ruby-on-rails-3.2
当有人试图登录我的应用程序(跟踪暴力尝试)时,我需要写一个日志.我还决定记录成功的身份验证.所以我创建了一个SessionsController <Devise :: SessionsController并试图覆盖会话#create方法,如:https://gist.github.com/3884693
第一部分完美地运行,但是当auth failes rails抛出某种异常并且永远不会到达if语句.所以我不知道该怎么办.

设计控制器中的create操作调用warden.authenticate !,它尝试使用提供的参数对用户进行身份验证.如果验证失败,则验证!将调用设计失败应用程序,然后运行SessionsController #new动作.请注意,如果身份验证失败,您对create操作的任何过滤器都将无法运行.
因此,解决方案是在新操作之后添加一个过滤器,用于检查env ["warden.options"]的内容并采取相应的操作.
我尝试了这个建议,并能够记录成功和失败的登录尝试.这是相关的控制器代码:
class SessionsController < Devise::SessionsController
after_filter :log_failed_login, :only => :new
def create
super
::Rails.logger.info "\n***\nSuccessful login with email_id : #{request.filtered_parameters["user"]}\n***\n"
end
private
def log_failed_login
::Rails.logger.info "\n***\nFailed login with email_id : #{request.filtered_parameters["user"]}\n***\n" if failed_login?
end
def failed_login?
(options = env["warden.options"]) && options[:action] == "unauthenticated"
end
end

我有同样的问题,但无法解决它,"warden.options"因为在我的情况下,这些在重定向到sessions#new操作之前已被清除。寻找到几个选择,我判断是太脆(因为涉案延长一些设计类和走样现有方法)后,我结束了使用一些提供的回调Warden。它对我来说效果更好,因为回调是在当前请求-响应周期内调用的,并且参数都保存在env对象中。
这些回调被命名并似乎旨在解决这个问题和相关问题。他们被记录在案!
Warden 支持以下回调warden-1.2.3:
after_set_userafter_authentication (用于记录成功登录)after_fetch(别名为after_set_user)before_failure (用于记录失败的登录 - 下面的示例)after_failed_fetchbefore_logouton_request每个回调都直接在Warden::Manager类上设置。为了跟踪失败的身份验证尝试,我添加了以下内容:
Warden::Manager.before_failure do |env, opts|
email = env["action_dispatch.request.request_parameters"][:user] &&
env["action_dispatch.request.request_parameters"][:user][:email]
# unfortunately, the User object has been lost by the time
# we get here; so we take a db hit because I care to see
# if the email matched a user account in our system
user_exists = User.where(email: email).exists?
if opts[:message] == :unconfirmed
# this is a special case for me because I'm using :confirmable
# the login was correct, but the user hasn't confirmed their
# email address yet
::Rails.logger.info "*** Login Failure: unconfirmed account access: #{email}"
elsif opts[:action] == "unauthenticated"
# "unauthenticated" indicates a login failure
if !user_exists
# bad email:
# no user found by this email address
::Rails.logger.info "*** Login Failure: bad email address given: #{email}"
else
# the user exists in the db, must have been a bad password
::Rails.logger.info "*** Login Failure: email-password mismatch: #{email}"
end
end

我希望您也可以使用before_logout回调来跟踪注销操作,但我尚未对其进行测试。似乎也有prepend_回调的变体。
Prakash的回答很有帮助,但是依靠它SessionsController#new作为副作用并不理想。我相信这更干净:
class LogAuthenticationFailure < Devise::FailureApp
def respond
if request.env.dig('warden.options', :action) == 'unauthenticated'
Rails.logger.info('...')
end
super
end
end
...
Devise.setup do |config|
config.warden do |manager|
manager.failure_app = LogAuthenticationFailure
end
