我目前正在开发一个 Ruby-on-Rails 网络应用程序，该应用程序通过 PayPal 的 Express Checkout 和 ActiveMerchant 接受 PayPal 付款。我已经对 ActiveMerchant 的支持进行了几项研究，以确定客户/买家是否使用经过验证或未经验证的 PayPal 帐户付款，但我没有找到有用的指南。
我还发现 ActiveMerchant 目前没有很好的文档记录，所以它根本没有帮助。
以下是我的项目目前正在使用的相关代码。在 PaymentsController#purchase 上，我暂时使用EXPRESS_GATEWAY.purchase 方法调用返回的对象的#params['protection_eligibility']和方法来评估 PayPal 客户/买家是否拥有经过验证/未经验证的 PayPal 帐户。后来发现这并不是了解客户账户状态的可靠依据。#params['protection_eligibility_type']ActiveMerchant::Billing::PaypalExpressResponse
我希望有人能给我一个智慧，让我知道 PayPal 客户/买家是否有一个使用 Ruby-on-Rails 的 ActiveMerchant 或使用 Rails 上的其他替代品的已验证/未验证帐户。
