每日总结

1.今天继续安卓关于http的学习

通过refresh响应头，让浏览器隔几秒后跳转至别的页面：

public class ServletFour extends HttpServlet {
    public int second = 0;
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        //1.浏览器每隔2秒定时刷新页面
//        resp.setHeader("refresh", "2");
//        resp.getWriter().write(++second + "");
//        System.out.println("doGet方法被调用~");
        
        //2.进入页面5s后，然页跳到百度~
        resp.setHeader("refresh", "5;url='http://www.baidu.com'");
        resp.getWriter().write("HE HE DA~");
    }
    
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException ,IOException 
    {
        doGet(req, resp);
    };
