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实现贝宝服务。我的开发者的paypal帐户是为API证书凭证设置的。以下代码在使用API签名时运行良好，但在尝试实现API证书时出现错误。有人能帮帮忙吗？

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)

好吧，我知道我错在哪里了。我检查了证书文档，发现我应该使用:pem而不是: ActiveMerchant。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
