本文介绍了Java获取此次请求URL以及获取服务器根路径的方法,并且进行举例说明,感兴趣的朋友可以学习借鉴下文的内容。
一、 获取此次请求的URL
String requestUrl = request.getScheme() //当前链接使用的协议 +"://" + request.getServerName()//服务器地址 + ":" + request.getServerPort() //端口号 + request.getContextPath() //应用名称,如果应用名称为 + request.getServletPath() //请求的相对url + "?" + request.getQueryString(); //请求参数
举例:
http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1<Context path="world" docBase="/home/webapps" debug="0" reloadable="true"/>request.getScheme() = "http";request.getServerName() = "127.0.0.1";request.getServerPort() = "8080";request.getContextPath() = "world";request.getServletPath() = "index.jsp";request.getQueryString() = "name=lilei&sex=1";http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1<Context path="" docBase="/home/webapps" debug="0" reloadable="true"/>request.getScheme() = "http";request.getServerName() = "127.0.0.1";request.getServerPort() = "8080";request.getContextPath() = "";request.getServletPath() = "world/index.jsp";request.getQueryString() = "name=lilei&sex=1";
二、获取服务器根路径
<% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %>
使用如下:
<head><link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/framework/themes/default/easyui.css"><link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/framework/themes/icon.css"><link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/base.css"><script src="<%=basePath%>static/javascript/framework/jquery.min.js"></script><script src="<%=basePath%>static/javascript/framework/jquery.easyui.min.js"></script><script src="<%=basePath%>static/javascript/framework/easyui-lang-zh_CN.js"></script><script src="<%=basePath%>static/javascript/framework/easyui-util.js"></script></head>
以上就是Java获取此次请求URL以及服务器根路径的方法,希望对大家的学习有所帮助。
