这周在调支付宝的接口。期间需要把我方程序处理后的参数(交易金额)按照规定的格式传递给支付宝的接口。因为中途要设计到我方程序对一些数据的处理，所以并不方便直接传值过去。思来想去，决定先把我方的数据提交给webwork的Action进行处理，也就是对数据库进行操作；然后把交易金额以及支付宝接口需要的其他参数一并传递给一个JSP页面，并让这个JSP页面在把action直接指向支付宝的网关接口，注意：中间过程中这个JSP页面时不显示出来的。为此，做了如下测试：建立两个JSP页面传值,tes1.jsp和test2.jsp。代码如下：
<%@pagelanguage="java"import="java.util.*"pageEncoding="GBK"%>
<%
Stringpath=request.getContextPath();
StringbasePath=request.getScheme()+"://"+request.getServerName()
+":"+request.getServerPort()+path+"/";%>
>
<basehrefbasehref="<%=basepath%>">
