“未定义的方法`has_key？”对于# 发布于 2024-11-10 04:08:42 字数 3672 浏览 0 评论 0 原文 我尝试在 Rails 应用程序中启用信用卡计费，但在尝试创建订单时收到以下错误：未定义方法“has_key？”对于 # 引用的代码是订单模型中的 purchase 方法： class Order < ActiveRecord::Base ... include ActiveMerchant::Billing ... def credit_card @credit_card ||= ActiveMerchant::Billing::CreditCard.new( :type => card_type, :number => card_number, :month => card_expires_on.month, :year => card_expires_on.year, :first_name => first_name, :last_name => last_name, :verification_value => card_verification ) end def purchase response = GATEWAY.authorize(price_in_cents, credit_card) if response.success? GATEWAY.capture(price_in_cents, response.authorization) cart.update_attribute(:purchased_at, Time.now) else raise StandardError, response.message end end end 我使用的是 Paypal Express 网关，其 Active商家库定义 purchase 如下： def purchase(money, options = {}) requires!(options, :token, :payer_id) commit 'DoExpressCheckoutPayment', build_sale_or_authorization_request('Sale', money, options) end private def build_get_details_request(token) xml = Builder::XmlMarkup.new :indent => 2 xml.tag! 'GetExpressCheckoutDetailsReq', 'xmlns' => PAYPAL_NAMESPACE do xml.tag! 'GetExpressCheckoutDetailsRequest', 'xmlns:n2' => EBAY_NAMESPACE do xml.tag! 'n2:Version', API_VERSION xml.tag! 'Token', token end end xml.target! end def build_sale_or_authorization_request(action, money, options) currency_code = options[:currency] || currency(money) xml = Builder::XmlMarkup.new :indent => 2 xml.tag! 'DoExpressCheckoutPaymentReq', 'xmlns' => PAYPAL_NAMESPACE do xml.tag! 'DoExpressCheckoutPaymentRequest', 'xmlns:n2' => EBAY_NAMESPACE do xml.tag! 'n2:Version', API_VERSION xml.tag! 'n2:DoExpressCheckoutPaymentRequestDetails' do xml.tag! 'n2:PaymentAction', action xml.tag! 'n2:Token', options[:token] xml.tag! 'n2:PayerID', options[:payer_id] xml.tag! 'n2:PaymentDetails' do xml.tag! 'n2:OrderTotal', localized_amount(money, currency_code), 'currencyID' => currency_code # All of the values must be included together and add up to the order total if [:subtotal, :shipping, :handling, :tax].all?{ |o| options.has_key?(o) } xml.tag! 'n2:ItemTotal', localized_amount(options[:subtotal], currency_code), 'currencyID' => currency_code xml.tag! 'n2:ShippingTotal', localized_amount(options[:shipping], currency_code),'currencyID' => currency_code xml.tag! 'n2:HandlingTotal', localized_amount(options[:handling], currency_code),'currencyID' => currency_code xml.tag! 'n2:TaxTotal', localized_amount(options[:tax], currency_code), 'currencyID' => currency_code end xml.tag! 'n2:NotifyURL', options[:notify_url] xml.tag! 'n2:ButtonSource', application_id.to_s.slice(0,32) unless application_id.blank? xml.tag! 'n2:InvoiceID', options[:order_id] xml.tag! 'n2:OrderDescription', options[:description] end end end end xml.target! end 看起来我的订单模型中的 credit_card 参数被视为在 Active Merchant 库中调用 has_key? 的 options，其 CreditCard 代码未定义 has_key?。我正在使用最新版本的 Active Merchant。 有什么帮助吗？ 原文 收藏 0 分享到微信 分享到QQ 分享到微博 如果你对这篇内容有疑问，欢迎到本站社区发帖提问 参与讨论，获取更多帮助，或者扫码二维码加入 Web 技术交流群。

好像有些网关有不同的购买方式。

TrustCommerceGateway（代码显示在https://github.com/activemerchant/active_merchant）

def purchase(money, creditcard_or_billing_id, options = {})

https://github.com/activemerchant/active_merchant/blob/b417c77d43 5b8d163b6e77588c80ac347cc1316a /lib/active_merchant/billing/gateways/trust_commerce.rb#L164

PayPalExpressCheckoutGateway

def purchase(money, options = {})

所以看起来如果你想使用 ActiveMerchant::Billing::CreditCard 与 Paypal，你必须使用 PaypalGateway （而不是 PaypalExpressCheckoutGateway）
