ruby-on-rails - 如何使用 paypal/ruby on rails/active merchant 创建安全的信用卡网关

Question

我现在正在使用 Active Merchant 和 PayPal 沙箱创建商店。它似乎工作正常，但我认为它甚至不安全。我真的不太了解 HTTPS 以及如何实现安全连接。

我目前正在 session 中传递信用卡和账单信息(可能不是最明智的想法)。我当前的代码发布在下面。我真的需要帮助，了解要采取什么方向和步骤才能使它成为一个安全、可用的商店。

 def payment
session[:billing_address] = params[:billing_address] 
 end

 def summary
    @credit_card = params[:credit_card]
    session[:credit_card] = params[:credit_card]
    @billing_address = session[:billing_address]
    @cart = get_cart
    @purchases  = @cart.purchases
    @total = @cart.total
 end

 def finish
     @cart = get_cart
     @total = @cart.total

     credit_card = ActiveMerchant::Billing::CreditCard.new( session[:credit_card] )

     billing_address = session[:billing_address]

     flash[:notice] = credit_card.errors and return unless credit_card.valid?

     gateway = ActiveMerchant::Billing::PaypalGateway.new(:login=>$PAYPAL_LOGIN, :password=>$PAYPAL_PASSWORD)

     res = gateway.authorize(@total, credit_card, :ip=>request.remote_ip, :billing_address=>billing_address)

     if res.success?
        gateway.capture(@total, res.authorization)
        flash[:notice] = "Authorized" 
     else
        flash[:notice] = "Failure: " + res.message.to_s
     end    
  end

关于如何实现 ssl 有一个很好的 railscast。
