這個 gem 的目的是要串接 智付通（原智付寶） 的金流，不過不是只有單純的 API 封裝，是透過 active_merchant 和 offsite_payments 包裝後可以快速的在 Rails 上使用。

另外非常感謝 active_merchant_allpay。

Gemfile 中加入這一行

gem 'active_merchant_pay2go'

透過 bundle 安裝:

$ bundle

• 建議第一次使用的人可以先看一下官方的文件... Official API 。

• 建立 config/initializers/pay2go.rb

rails g pay2go:install

• 到智付寶上申請申請相關的 key 並放入 config/initializers/pay2go.rb 中。

# Example
OffsitePayments::Integrations::Pay2go.setup do |pay2go|
  # You have to apply credential below by yourself.
  pay2go.merchant_id = '123456'
  pay2go.hash_key    = 'xxx'
  pay2go.hash_iv     = 'yyy'
end

• 環境設定:

# config/environments/development.rb
config.after_initialize do
  ActiveMerchant::Billing::Base.mode = :development
end

# config/environments/production.rb
config.after_initialize do
  ActiveMerchant::Billing::Base.mode = :production
end

<% payment_service_for  @order,
                        @order.user.email,
                        service: :pay2go,
                        html: { :id => 'pay2go-form', :method => :post } do |service| %>
  <% service.time_stamp @order.created_at %>
  <% service.merchant_order_no @order.id %>
  <% service.amt @order.total_amount.to_i %>
  <% service.item_desc @order.description %>
  <% service.email @order.user.email %>
  <% service.login_type 0 %>
  <% service.encrypted_data %>
  <%= submit_tag '付款' %>
<% end %>

這段程式碼只有實做了很基本的功能。

如果有更多的設定，建議看一下官方文件有沒有支援。

範例 （很簡陋的範例）.
