肖威洞察 | [Ruby on Rails]支付宝app支付接口

两个action都是post请求，在routes配置好。


def alipay

  @order = Order.includes(:good).find(params[:order_id])
  biz_content = {
      timeout_express: "30m",
      product_code: "QUICK_MSECURITY_PAY",
      total_amount: @order.buy_count * @order.amount,
      subject: "#{@order.good.name} x #{@order.buy_count}",
      body: "#{params[:order_id]}",
      out_trade_no: @order.order_number,
    }

  result = {
    :app_id     => Settings.alipay.app_id,
    :method     => "alipay.trade.app.pay",
    :charset    => "utf-8",
    :sign_type  => "RSA",
    :sign       => "your pkcs8格式的private key，使用openssl生成的，供android调用",
    :timestamp   => Time.now.strftime('%Y-%m-%d %H:%M:%S'),
    :version     => "1.0",
    :notify_url  => "http://api.×××××.com/interface/payments/alipay_notify",
    :bit_content => biz_content,
    :bit_content_json => biz_content.to_json
  }
  render json: result

end
