ActiveMerchant 是否支持基于订阅的交易

发布于 2024-10-02 09:57:44 字数 264 浏览 1 评论 0原文

我正在尝试将 ActiveMerchant 集成到我的 Rails 应用程序中。我有某些计划，如果订阅就会限制用户访问。由于你们所有人可能都知道什么是基于订阅的应用程序，因此我不会解释我的应用程序。请给我推荐一些实现这一目标的例子。我已经看过 Railscasts 第 141 集到 146 集，但 Ryan 只演示了 Paypal Web Payments Standard 和 Paypal Web Payments Pro。我也读了很多博客，但没有帮助。

请帮忙。

提前致谢。

迟到总比不到好，不是吗？

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

这是一个有效的演示片段。我只是不确定几点（一旦弄清楚我会立即更新答案），它们是：

无论设置如何：initial_amount，仅设置计费协议都不会显示任何价格。包含商品将在 billing_agreement[:description] 上方显示该商品的价格。所以我不确定这如何影响捕获，这就是我这些天正在测试的内容。

IPN 通知。它们在下面的代码片段中丢失了。更新如下...

类 PaymentsController <应用控制器
  包括 ActiveMerchant::Billing


  # GET /订阅/:id/结帐
  默认结帐
    payment_request = PAYPAL_EXPRESS_GATEWAY.setup_purchase(@subscription.price_in_cents,
        ：计费协议=> {
            ：类型=> “定期付款”，
            ：描述=> ‘认购协议’，
        },

        ：货币=> '瑞士法郎',
        :no_shipping =>真的，
        :allow_guest_checkout =>真的，
        :allow_note =>;错误的，
        :初始金额=> @subscription.price_in_cents，
        : 语言环境 => '德',
        :ip =>请求.remote_ip,
        :return_url => url_for(:action => :confirm, :only_path => false),
        :cancel_return_url => url_for(:action => :取消, :only_path => false),
        # 看起来 :notify_url 没有在这里使用，而是在下一节中使用 
    ）

    如果 payment_request.success？
      重定向到 PAYPAL_EXPRESS_GATEWAY.redirect_url_for( payment_request.token )
    别的
      # 渲染一些非正式的东西
      渲染：文本=> payment_request.inspect.to_s 并返回
    结尾
  结尾

  # POST /订阅/:id/确认 
  # 具有 token 和 PayerID 的参数
  确定确认
    配置文件 = PAYPAL_EXPRESS_GATEWAY.recurring(@subscription.price_in_cents, nil, 
        ：描述=> ‘认购协议’，
        :开始日期 => Date.tomorrow, # 如果日期不是将来的日期，PayPal 会抛出错误
        ：句号=> '年'，
        ：频率=> 1、
        ：金额=> @subscription.price_in_cents，
        ：货币=> '瑞士法郎',
        :初始金额=> @subscription.price_in_cents，
        ：auto_bill_outstanding =>真的，

        ：令牌=>参数[:令牌]
    ）

    # 配置文件有 profile_id 和 profile_status。记住状态，因为它通过 IPN 更新。
    @debug = {:params =>; params.inspect.to_s, :profile => profile.inspect.to_s }

    # 渲染一些非正式的东西
    渲染：文本=> @debug.to_s 并返回
  结尾


  # 实施而不是仅仅记录
  默认通知
    日志 = Logger.new 'log/ipn.log'
    log.debug params.inspect
    渲染：文本=> params.inspect.to_s 并返回
  结尾


  # 省略私有方法

结尾

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

编辑关于贝宝和定期计费的更新、修订的截屏视频是通过单独的贝宝-重复出现的宝石。如果您无法让它与 ActiveMerchant 一起使用，这也许会有所帮助。

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.
