ruby-on-rails – Rails – 使用paypal-recurring gem处理PayPal

我使用 paypal-recurring gem来处理Rails应用程序中的定期付款.我的大多数代码来自这个优秀的 Railscast,但我还想添加一个payment_notification模型来接受IPN回调并存储任何相关数据.这个 Railscast讨论了如何设置通知.但是,我很难搞清楚如何将paypal-recurring gem IPN回调发送到我的PaymentNotification模型.

如何设置：ipn_url以正确地将IPN回调写入我的PaymentNotification模型.到目前为止我尝试了以下内容：

1)将ipn_url：“http://my-app-name.com/payment_notifications”添加到流程方法(在选项下)或payment_notifications_url

2)尝试在GitHub issue page底部建议的解决方案

3)使用Paypal的即时付款通知(IPN)模拟器发送到“http://my-app-name.com/payment_notifications”,但我收到一个错误：IPN传递失败. HTTP错误代码401：未经授权

编辑

我已经能够成功模拟IPN到我的payments_notifications_url的交付.现在我只需要弄清楚如何指出定期发送的gem将ipn发送到那里.

任何指针都将非常感激.以下是我目前的一些代码.如果我遗忘任何相关部分,请告诉我.

PaypalPayment模型

class PaypalPayment
   def initialize(subscription)
     @subscription = subscription
   end

   def checkout_details
     process :checkout_details
   end

   def checkout_url(options)
     process(:checkout,options).checkout_url
   end

   def make_recurring
     process :request_payment
     process :create_recurring_profile,period: :monthly,frequency: 1,start_at: Time.zone.now
   end

   def cancel_recurring
     process :cancel
   end

 private

   def process(action,options = {})
     options = options.reverse_merge(
       token: @subscription.paypal_payment_token,payer_id: @subscription.paypal_customer_token,description: @subscription.plan.name,amount: @subscription.plan.monthly_price,currency: "JPY"
     )
     response = PayPal::Recurring.new(options).send(action)
     raise response.errors.inspect if response.errors.present?
     response
   end
 end

PaymentNotifications控制器

class PaymentNotificationsController < ApplicationController
   protect_from_forgery :except => [:create]

   def create
     PaymentNotification.create!(:params => params,:status => params[:payment_status],:transaction_id => params[:txn_id])
     render :nothing => true
   end
 end

def process(action,ipn_url: "https://my-app-name.com/payment_notifications",currency: "JPY"
    )
     response = PayPal::Recurring.new(options).send(action)
     raise response.errors.inspect if response.errors.present?
     response
   end
