ruby-on-rails - 在 rails 3.2 中使用 paypal 预先批准的付款

Question

我将此信息发送到 paypal 以使用预批准付款功能:

response = gateway.preapprove_payment( 
  :return_url =>  user_orders_url(current_user),
  :cancel_url => user_orders_url(current_user),
  :requestEnvelope => {"errorLanguage" => "en_US"},
  :start_date => Time.now,
  :end_date => Time.now + (60*60*24) * 30,
  :currency_code =>"USD",
  :senderEmail =>"email address of sender",
  :max_amount => "20.00",
  :maxNumberOfPayments => "1",
  :notify_url => ipn_notification_user_orders_url(current_user),
  )
 redirect_to (gateway.redirect_url_for(response["preapprovalKey"]))
 p response

我在 paypal 页面收到一条消息:

This transaction is invalid. Please return to the recipient's website and try again.

我正在使用此 gem https://github.com/jpablobr/active_paypal_adaptive_payment/blob/master/lib/active_merchant/billing/gateways/paypal_adaptive_payment.rb 中的方法 build_preapproval_payment

这是我的日志控制台的输出:

哪里出错了？

谢谢!

好吧，根据我对该 gem 的源代码的调查，预批准付款的正确 redirect_url 方法是 redirect_pre_approval_url_for

redirect_pre_approval_url_for(token)
