获取表单的代码

<%@ page language="java" import="java.util.\*" pageEncoding="gb2312"%>  
<%  
String path = request.getContextPath();  
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

       for(int i=0;i<info.length;i++)\{  
       out.println(info\[i\]);  
       \}  
        %>  
    
  </body>

</html>

request.setCharacterEncoding("gb2312");

这段代码是为了防止中文输入的东西无法获取，产生乱码。
