执行结果

• XML原文：

<?xml version="1.0" encoding="utf-8" ?

>

<MoBaoAccount MessageType="UserMobilePay" PlatformID="b2ctest">

    <OrderNo>M20150521084825</OrderNo>

    <TradeAmt>5000.00</TradeAmt>

    <Commission>0.5</Commission>

    <UserID>xiaolong</UserID>

    <MerchID>xiaolong1</MerchID>

    <tradeType>0</tradeType>

    <CustParam>123</CustParam>

    <NotifyUrl>http://mobaopay.com/callback.do</NotifyUrl>

    <TradeSummary>订单</TradeSummary>

</MoBaoAccount>
