paypal - 在 ActiveMerchant 中使用 Paypal API 证书

Question

我正在尝试在我的应用程序中使用 ActiveMerchant 实现 Paypal 服务。我的开发者的 paypal 帐户是为 API 证书凭据设置的。以下代码在与 API 签名一起使用时运行良好，但在我尝试实现 API 证书时出现错误。有人可以帮忙吗？

PAYPAL_CERT_PEM = File.read("#{Rails.root}/certs/paypal_cert_dev.pem")
config.after_initialize do
  ActiveMerchant::Billing::Base.mode = :test 
  paypal_options = {
    :login => "****************",
    :password => "**************",
    :certificate => PAYPAL_CERT_PEM
  }
  ::STANDARD_GATEWAY = ActiveMerchant::Billing::PaypalGateway.new(paypal_options)
end

错误:

/Library/Ruby/Gems/1.8/gems/activemerchant-1.12.1/lib/active_merchant/billing/gateways/paypal/paypal_common_api.rb:72:in `initialize': An API Certificate or API Signature is required to make requests to PayPal (ArgumentError)

Answer 1

好吧，我知道我错在哪里了。我检查了 ActiveMerchant 文档，发现我应该使用 :pem 而不是 :certificate。所以，代码应该是这样的——

PAYPAL_CERT_PEM = File.read("#{Rails.root}/certs/paypal_cert_dev.pem")
config.after_initialize do
  ActiveMerchant::Billing::Base.mode = :test 
  paypal_options = {
    :login => "****************",
    :password => "**************",
    :pem => PAYPAL_CERT_PEM
  }
  ::STANDARD_GATEWAY = ActiveMerchant::Billing::PaypalGateway.new(paypal_options)
end
