Rails：已完成401未经授权

Question

我收到了这个错误，但我不知道为什么。我特意排除了CSRF检查。 #webhook方法即使在生产中也可以使用。其他类似的问题是关于Devise，但我没有在这个控制器中使用Devise。

stripes_controller.rb

class StripesController < ApplicationController
  Stripe.api_key = ENV['STRIPE_PRIVATE']
  protect_from_forgery :except => [:webhook, :create]

  def show
  end

  def create
    # Amount in cents
    @amount = params[:amount]

    customer = Stripe::Customer.create(
      :email => params[:stripeEmail],
      :source  => params[:stripeToken]
    )

    charge = Stripe::Charge.create(
      :customer    => customer.id,
      :amount      => @amount,
      :description => 'Membership Fee',
      :currency    => 'usd'
    )

    render :show
  rescue Stripe::CardError => e
    flash[:error] = e.message
    redirect_to stripe_path
  end

routes.rb

resource :stripe do

默认情况下，Rails位于:debug日志级别。 http://guides.rubyonrails.org/v5.0/debugging_rails_applications.html#log-levels

我能够通过设置

来重现它 devise.rb

config.timeout_in = 1.minute # 8.hours

如果我已登录并处于活动状态，它可以正常工作，但如果会话超时，则会导致此401问题。

这是来自浏览器的请求/响应。它显示成功和302响应，而不是401.它在服务器控制台日志中显示401。

POST /stripe/ HTTP/1.1
Host: localhost:3000
Connection: keep-alive
Content-Length: 82
Cache-Control: max-age=0
Origin: http://localhost:3000
Content-Type: application/x-www-form-urlencoded
...

HTTP/1.1 302 Found
X-Frame-Options: SAMEORIGIN
X-XSS-Protection: 1; mode=block
X-Content-Type-Options: nosniff

Content-Type: text/html; charset=utf-8

浏览器网络日志中没有一个401响应，甚至按状态排序，即使使用Preserver Log也是如此。

Answer 1

我按照Marek的建议将问题追踪到user_signed_in?。该功能将 HALT 执行并发出302重定向，同时在服务器日志中打印401！

devise.rb

config.timeout_in = 1.minute # 8.hours

stripes_controller.rb

class StripesController < ApplicationController
  layout false

show.haml

%h2 Thank you!
%p 
  Your payment of 
  %strong= number_to_currency(@amount.to_i * 0.01)
  has been received.
- if user_signed_in?
  Signed in
- else
  Signed out

如果用户已登录，则页面将正常加载。如果用户的会话过期，则设计将重定向并设置Flash消息！

我无法找到一种方法来检查用户是否在没有重定向的情况下登录。

https://duckduckgo.com/?q=rails+devise+%22user_signed_in%22+stop+redirecting&ia=qa

在搜索方法时，

user_signed_in?即使在Devise API文档中也是如此！我希望有一个可选的论点。

http://www.rubydoc.info/github/plataformatec/devise/Devise

所以我设置了layout false，因此它停止使用包含application.haml的{​​{1}}。我希望有更好的方法。

Answer 2

HTTP代码401 Unauthorized用于身份验证（https://httpstatuses.com/401）。它与CSRF无关。在这种情况下，它会引发ActionController :: InvalidAuthenticityToken。

我非常确定您的ApplicationController中有一个需要用户身份验证的before_action（或者在routes.rb中，或者在nginx / Apache的配置中）。
