列出所有请求表单提交数据的通用jsp脚本，调试可以使用

 

 

将代码保存为 showRequestParameters.jsp

 

只要在处理表单的页面包含该文件即可

<%-- A Jsp Component that Shows Request Parameters
     Include this page to view request parameters.
     Example Use: 
            ...
            <h2>Request Parameters</h2>
          <jsp:include page='showRequestParameters.jsp'/>
          ...
--%>
<%
   java.util.Enumeration e = request.getParameterNames();
   while(e.hasMoreElements()) {
      String name = (String)e.nextElement();
      String[] values = request.getParameterValues(name);

      for(int i=0; i < values.length; ++i) {
         String next = values[i];
         if(i == 0) { %>
            <b><%= name %>:</b> <%= next %>
<%       }
         else { %>
            , <%= next %>
<%       }
       } %>
      <br>
<% }
%>
