}
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>
