ActiveMerchant是否支持基于订阅的事务 [英] Does ActiveMerchant support Subscription Based transaction

问题描述

我正在尝试将ActiveMerchant集成到我的Rails应用程序中。我有一定的计划，如果订阅限制用户访问。正如你们所有人都知道什么是基于订阅的应用程序，我不会解释我的应用程序。请为此提供一些示例。我已经看过了第141到146集的列表，但Ryan只演示了Paypal Web Payments Standard和Paypal Web Payments Pro。我也读了一些博客，但没有帮助。

请帮助。

谢谢Advance。

解决方案

迟到比从未好过吧？

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

下面是一个适用的演示片段。我只是不确定几点（我会尽快更新答案），它们是：

• 无论设置：initial_amount ，仅设置结算协议就不会显示任何价格。包括一个项目将显示该项目的价格高于 billing_agreement [：description] 。所以我不确定这是如何影响捕捉的，这是我现在测试的。



• IPN通知。它们在以下代码片段中缺失。更新以下...

   类PaymentsController< ApplicationController的
  包括ActiveMerchant ::结算
   
   
  ＃GET /订阅/：ID /结帐
   DEF结账
   payment_request = PAYPAL_EXPRESS_GATEWAY.setup_purchase（@subscription。 price_in_cents，
  ：billing_agreement => {
  ：type =>'RecurringPayments'，
  ：description =>'订阅协议'，
  }，
   
  ：currency =>'CHF'，
  ：no_shipping => true，
  ：allow_guest_checkout => true，
  ：allow_note => false，
  ： initial_amount => @ subscription.price_in_cents，
  ：区域设置=> '去'，
  ：IP => request.remote_ip，
  ：return_url => url_for（：动作=> ;：confirm，：only_path => false），
  ：cancel_return_url => url_for（：action =>：cancel，：only_path => false），
  ＃看起来像：notify_url不是在这里使用，但在下一节
  ）
   
  如果payment_request.success？ 
   redirect_to PAYPAL_EXPRESS_GATEWAY.redirect_url_for（payment_request.token）
   else 
  ＃呈现一些非正式的
   render：text => payment_request.inspect.to_s并返回
  结束
  结束
   
  ＃POST /订阅/：id / confirm 
  ＃带有令牌和PayerID的参数
   def确认
  轮廓= PAYPAL_EXPRESS_GATEWAY.recurring（@ subscription.price_in_cents，零，
  ：描述=> '订阅协议'，
  ：START_DATE => Date.tomorrow，＃贝抛出如果错误日期不在将来
  ：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有profile_id和profile_status。记住状态，因为这通过IPN更新。 
   @debug = {：params => params.inspect.to_s，：profile => profile.inspect.to_s} 
   
  ＃渲染一些非正式的
   render：text => @ debug.to_s并返回
  结束
   
   
  ＃实现而不是仅仅记录
   def通知
   log = Logger.new'log / ipn.log '
   log.debug params.inspect 
   render：text => params.inspect.to_s并返回
  结束
   
   
  ＃私有方法省略
   
  结束
    

您想查看 PaypalRecurringAPI 和 PaypalExpressGateway / PayPalGateway 查看哪些选项被处理以及xml请求在哪个位置。

编辑关于PayPal和定期结算的更新的，经过修改的截屏视频是通过单独的贝宝 - 复发宝石。如果你无法使用ActiveMerchant，这可能会有所帮助。

I am trying to integrate ActiveMerchant in my rails app. I have certain plans that if subscribed limit the user access. As you all guyz might be knowing what a subscription based app is, I am not going into explaining my app. Please suggest me some examples for making this happen. I have already viewed the railscasts episodes 141 through 146 but Ryan has only demonstrated Paypal Web Payments Standard and Paypal Web Payments Pro. I have also read a bunch of blogs but it didn't help.

Please help.

Thanks in Advance.

解决方案

Better late than never, huh?

The actual master branch of ActiveMerchant contains a recurring class integrated into both the PaypalGateway and PaypalExpressGateway.

Here's a demo snippet which works. I'm just not sure about a few points (I will update the answer as soon as I figured them out), which are:

• Just setting the billing agreement does not show any price regardless of setting :initial_amount. Including an Item will show the item's price above the billing_agreement[:description]. So I am not sure how this affects capturings, which is what I am testing these days.

• IPN notifications. They're missing in the following snippet. Update following...

  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
  

You want to have a look into PaypalRecurringAPI and PaypalExpressGateway / PayPalGateway to see which options are processed and in which place of the xml request.

edit The newer, revised screencast about paypal and recurring billing is done with a separate paypal-recurring gem. Maybe this helps if you can't get it to work with ActiveMerchant.
