PayPal通知未收到Rails 4

Question

我正在做一個Web應用程序。 我想讓用戶使用貝寶付款。 用戶付款后，我希望PayPal向我發送通知以更新表“ Bookings”的“ paid_at”列。 為了做到這一點，我正在使用IPN。 這是我的代碼：

控制者

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

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

end

視圖

<%= link_to "Pay tour", @booking.paypal_url(tour_booking_url(@tour, @booking), payment_notifications_url) %>

Booking.rb

def paypal_url(return_url, notify_url)
    values = {
        :business => 'tourify-facilitator@gmx.com',
        :cmd => '_cart',
        :upload => 1,
        :return => return_url,
        :notify_url => notify_url,
        :invoice => id,
        :currency_code => tour.currency
    }
    values.merge!({
        "amount_1" => tour.price,
        "item_name_1" => tour.title,
        "item_number_1" => tour.id,
        "quantity_1" => '1'
    })
    "https://www.sandbox.paypal.com/cgi-bin/webscr?" + values.to_query
  end

模型類PaymentNotification <ActiveRecord :: Base

    belongs_to :booking
    serialize :params
    after_create :booking_as_purchased

    private

        def booking_as_purchased
            if status == "Completed"
                booking.update_attribute(:paid_at, Time.now)
            end
        end

end

耙路

 payment_notification GET    /payment_notifications/:id(.:format)           payment_notifications#show
                      PATCH  /payment_notifications/:id(.:format)        payment_notifications#update
                      PUT    /payment_notifications/:id(.:format)        payment_notifications#update
                      DELETE /payment_notifications/:id(.:format)        payment_notifications#destroy

如果我在本地主機上嘗試，則會創建通知，因為PayPal無法將其發送到本地主機。

curl -d "txn_id=1&invoice=2&payment_status=Completed" http://localhost:3000/payment_notifications

而且它正常工作！ ：D

但是，當我在Amazon上部署並且希望PayPal向我發送通知時，該通知不起作用，將創建一個空的PaymentNotification。 我究竟做錯了什么？

PS：我使用沙盒測試PayPal。

我有類似的問題。 要從PayPal接收IPN，需要在sendbox賣方帳戶首選項中設置通知URL。

要在本地測試IPN，可以使用https://ngrok.com/
