代码实例:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <% // 转到iq.jsp out.clearBuffer(); response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY); String param = request.getQueryString(); response.setHeader("Location","iq.jsp"+(param==null?"":("?"+param))); %>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <% // 转到iq.jsp out.clearBuffer(); response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY); String param = request.getQueryString(); response.setHeader("Location","iq.jsp"+(param==null?"":("?"+param))); %>
如上这段代码,将访问download.jsp的所有访问,永久重定向到 iq.jsp
参数也同时携带过去。
如果你的重定向是跨域的,或者使用完整路径,可以使用
response.setHeader("Location","http://www.laozizhu.com/iq.jsp"+(param==null?"":("?"+param)));
response.setHeader("Location","http://www.laozizhu.com/iq.jsp"+(param==null?"":("?"+param)));
这样你就可以指定完整的转向域名了。
用常用方式实现的是302跳转:
response.sendRedirect(http://www.baidu.com);
response.sendRedirect("http://www.baidu.com");
