Rails：已完成401未經授權

Question

我收到此錯誤，但我不知道為什么。 我專門排除CSRF檢查。 #webhook方法即使在生產中也有效。 其他類似的問題與Devise有關，但我不在此控制器中使用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

默認情況下，Rails是在:debug日志級別上。 http://guides.rubyonrails.org/v5.0/debugging_rails_applications.html#log-levels

我可以通過設置來重現它

devise.rb

config.timeout_in = 1.minute # 8.hours

如果我已登錄並處於活動狀態，則可以正常工作，但是如果會話超時，則將導致此401問題。

這是來自瀏覽器的請求/響應。 它顯示成功和302響應，而不是401。但是在服務器控制台日志中顯示401。

POST /stripe/ HTTP/1.1
Host: localhost:3000
Connection: keep-alive
Content-Length: 82
Cache-Control: max-age=0
Origin: http://localhost:3000

HTTP/1.1 302 Found

X-XSS-Protection: 1; mode=block
X-Content-Type-Options: nosniff

瀏覽器網絡日志中沒有一個401響應，即使使用Preserver Log也不按狀態排序。

我user_signed_in?問題跟蹤到user_signed_in? 如Marek所建議。 該功能將暫停執行並發出302重定向，同時在服務器日志中打印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

如果用戶已登錄，則該頁面將正常加載。 如果用戶的會話到期，則Devise將重定向並設置Flash消息 ！

我無法找到一種方法來檢查用戶是否在未重定向的情況下登錄。

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

user_signed_in? 搜索方法時，Devise API文檔中甚至都沒有！ 我希望有一個可選的參數。

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

所以我設置layout false所以停止使用application.haml包含user_signed_in? 。 我希望有更好的方法。

HTTP代碼401未經授權用於身份驗證（ https://httpstatuses.com/401 ）。 它與CSRF不相關。 在這種情況下，它將引發ActionController :: InvalidAuthenticityToken。

我很確定您的ApplicationController中有一個before_action，它需要用戶身份驗證（或者在routes.rb中，或者在nginx / Apache的配置中）。
