ruby-on-rails - ActiveMerchant 是否支持基于订阅的交易

Question

我正在尝试将 ActiveMerchant 集成到我的 Rails 应用程序中。我有某些计划，如果订阅则限制用户访问。因为你们所有人可能都知道什么是基于订阅的应用程序，所以我不打算解释我的应用程序。请给我一些实现这一目标的例子。我已经看过 railscasts 第 141 到 146 集，但 Ryan 只演示了 Paypal Web Payments Standard 和 Paypal Web Payments Pro。我也阅读了很多博客，但没有帮助。

请帮忙。

提前致谢。

迟到总比不到好吧？

ActiveMerchant 的实际主分支包含一个集成到 PaypalGateway 和 PaypalExpressGateway 中的循环类。

这是一个有效的演示片段。我只是不确定有几点(我会在弄清楚后立即更新答案)，它们是:

• 无论设置:initial_amount，仅设置结算协议(protocol)不会显示任何价格。包含项目将在 billing_agreement[:description] 上方显示该项目的价格。所以我不确定这会如何影响捕获，这是我最近正在测试的内容。

• IPN 通知。以下代码段中缺少它们。更新如下...

  class PaymentsController < ApplicationController
    include ActiveMerchant::Billing
  
  
    # GET /subscriptions/:id/checkout
    def checkout
      payment_request = PAYPAL_EXPRESS_GATEWAY.setup_purchase(@subscription.price_in_cents,
          :billing_agreement => {
              :type => 'RecurringPayments',
              :description => 'Subscription agreement',
          },
  
          :currency => 'CHF',
          :no_shipping => true,
          :allow_guest_checkout => true,
          :allow_note => false,
          :initial_amount => @subscription.price_in_cents,
          :locale => 'de',
          :ip => request.remote_ip,
          :return_url => url_for(:action => :confirm, :only_path => false),
          :cancel_return_url => url_for(:action => :cancel, :only_path => false),
          # Looks like :notify_url is not used here, but in the next section 
      )
  
      if payment_request.success?
        redirect_to PAYPAL_EXPRESS_GATEWAY.redirect_url_for(payment_request.token)
      else
        # Render something informal
        render :text => payment_request.inspect.to_s and return
      end
    end
  
    # POST /subscriptions/:id/confirm 
    # params having token and PayerID
    def confirm
      profile = PAYPAL_EXPRESS_GATEWAY.recurring(@subscription.price_in_cents, nil, 
          :description => 'Subscription agreement',
          :start_date => Date.tomorrow, # PayPal throws an error if the date is not in the future
          :period => 'Year',
          :frequency => 1,
          :amount => @subscription.price_in_cents,
          :currency => 'CHF',
          :initial_amount => @subscription.price_in_cents,
          :auto_bill_outstanding => true,
  
          :token => params[:token]
      )
  
      # profile has profile_id and profile_status. remember status because this gets updated via IPN.
      @debug = {:params => params.inspect.to_s, :profile => profile.inspect.to_s }
  
      # Render something informal
      render :text => @debug.to_s and return
    end
  
  
    # implement instead of just log
    def notification
      log = Logger.new 'log/ipn.log'
      log.debug params.inspect
      render :text => params.inspect.to_s and return
    end
  
  
    # Private methods omitted
  
  end
  

您想查看PaypalRecurringAPI和 PaypalExpressGateway/PayPalGateway查看处理了哪些选项以及在 xml 请求的哪个位置。
