(一) request

为什么80%的码农都做不了架构师？>>>   

　　主要方法如下,

<%@ page language="java" import="java.util.*" contentType="text/html;  charset=GB2312"%>


  
    
  
  
    
      request主要方法的调用示例:

      <%
          request.setAttribute("attr", "Hello!");
          out.print("attr属性值为:"+request.getAttribute("attr")+"
");
          out.print("上下文的路径为:"+request.getContextPath()+"
");
          out.print("Cookies:"+request.getCookies()+"
");
          out.print("Host:"+request.getHeader("Host")+"
");
          out.print("ServerName: "+request.getServerName()+"
");
          out.print("ServerPort: "+request.getServerPort()+"
");
          out.print("RemoteAddr: "+request.getRemoteAddr()+"
");
          request.removeAttribute("attr");
          out.print("属性移除操作之后attr属性的值为: "+request.getAttribute("attr")+"
");
       %>
    
  

运行结果:
