【中文标题】Rails PayPal 连锁支付费用【英文标题】:Rails PayPal Chained Payment Fees 【发布时间】:2014-07-03 00:29:20 【问题描述】:我有一个 ruby on rails 应用程序;在我希望一个用户能够向另一个用户支付的情况下,应用程序少 10% 的“佣金”;我的客户希望从应用程序保留的 10% 中提取费用,原因有两个:1)不给客户加分/减少客户 2)在一定数量的交易(每月)之后,该百分比显然会降低
因此,例如,如果用户 1 向用户 2 支付 100 美元,我希望它显示为:
用户 1 向应用发送 100 美元 -> 应用收到 97.09 美元(减去费用 100 美元)-> 应用程序向用户 2 发送 90.00 (90%) -> 用户 2 收到全部 90 美元(他方不收取任何费用)
但是,尽管将应用设置为主要接收方,但它仍将费用发布到次要接收方,使用户 2 支付费用。我还尝试将用户 2 设置为主要接收者,之后仅将 10% 转发到应用程序,但随后它将费用转移到主要接收者。我在代码中唯一更改的是收费百分比,以及主要/次要电子邮件。我的代码如下所示:
<!-- app/lib/pay_pal_api.rb -->
require "pp-adaptive"
class PayPalAPI
def self.payment_url(submission)
amount = submission.amount_in_cents.to_f / 100.0
recipient_cut = amount * 0.9
recipient_email = submission.submitter.paypal_email
client.execute(:Pay,
:action_type => "PAY",
:currency_code => "USD",
:cancel_url => "http://localhost:3000/my-studio",
:return_url => "http://localhost:3000/submissions/#submission.id",
:receivers => [
:email => recipient_email, :amount => recipient_cut, :primary => false ,
:email => "TestApp@gmail.com", :amount => amount, :primary => true
]
) do |response|
if response.success?
puts "Pay key: #response.pay_key"
# send the user to PayPal to make the payment
# e.g. https://www.sandbox.paypal.com/webscr?cmd=_ap-payment&paykey=abc
return client.payment_url(response)
else
puts "#response.ack_code: #response.error_message"
end
end
return nil
end
【问题讨论】:
【参考方案1】:使用feesPayer
字段并将其设置为PRIMARYRECEIVER
或SECONDARYONLY
,具体取决于谁先收到付款。这个的 ruby SDK 版本是fees_payer
——来自API Reference:
feesPayer xs:string (Optional) The payer of PayPal fees. Allowable values are:
SENDER – Sender pays all fees (for personal, implicit simple/parallel payments; do not use for chained or unilateral payments)
PRIMARYRECEIVER – Primary receiver pays all fees (chained payments only)
EACHRECEIVER – Each receiver pays their own fee (default, personal and unilateral payments)
SECONDARYONLY – Secondary receivers pay all fees (use only for chained payments with one secondary receiver)
EG:
client.execute(:Pay,
:action_type => "PAY",
:currency_code => "USD",
:cancel_url => "http://localhost:3000/my-studio",
:return_url => "http://localhost:3000/submissions/#submission.id",
:fees_payer => "SECONDARYONLY",
:receivers => [
:email => recipient_email, :amount => recipient_cut, :primary => false ,
:email => "TestApp@gmail.com", :amount => amount, :primary => true
]
)
【讨论】:
感谢您的回复;但我错了,它仍然向二级而不是一级收取费用。我在 :return_url 下面添加了::feesPayer => "PRIMARYRECEIVER",但它仍然无法正常工作。 叹息 你们知道如何延迟连锁付款吗?【参考方案2】:我发现在 pp-adaptive gem 中,它需要这样的语法:
:fees_payer => "PRIMARYRECEIVER",
现在它运行良好。

谢谢,我已经相应地更新了我的答案。这在我能找到的任何 SDK 文档中都不清楚。以上是关于Rails PayPal 连锁支付费用的主要内容,如果未能解决你的问题,请参考以下文章
