Generate payment url for web

    1. 银联签名 返回hash "交易时间", sign: "post给银联的hash" ruby UnionpayApp::Service.sign txtAmt, orderId #如下使用 options = UnionpayApp::Service.sign("100", "20150415122801272")
    1. 发送给银联post请求 换取tn值 ruby UnionpayApp::Service.post UnionpayApp::Service.sign(txtAmt, orderId) #如下使用 会返回tn值 UnionpayApp::Service.post(options)

  • 3.银联验签：当请求银联获取tn后，或者请求银联查询交易后，或者当交易完成后，银联通过backUrl、frontUrl返回你结果时要进行验签

    UnionpayApp::Service.verify options
    1. 查询交易是否成功 传入参数order_id ruby UnionpayApp::Service.query order_id, UnionpayApp::Service.sign(txtAmt, orderId)[:time] # 不要再做一次签名 取之前的options UnionpayApp::Service.query "20150415122801272", options[:time]
