JSP和JSTL获取服务器参数示例
复制代码 代码如下: <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> JSP方式
<% String SERVER_NAME = request.getServerName(); String SERVER_SOFTWARE = getServletContext().getServerInfo(); String SERVER_PROTOCOL = request.getProtocol(); Integer SERVER_PORT = request.getServerPort(); String REQUEST_METHOD = request.getMethod(); String PATH_INFO = request.getPathInfo(); String PATH_TRANSLATED = request.getPathTranslated(); String SCRIPT_NAME = request.getServletPath(); String DOCUMENT_ROOT = request.getRealPath("/"); String QUERY_STRING = request.getQueryString(); String REMOTE_HOST = request.getRemoteHost(); String REMOTE_ADDR = request.getRemoteAddr(); String AUTH_TYPE = request.getAuthType(); String REMOTE_USER = request.getRemoteUser(); String CONTENT_TYPE = request.getContentType(); Integer CONTENT_LENGTH = request.getContentLength(); String HTTP_ACCEPT = request.getHeader("Accept"); String HTTP_USER_AGENT = request.getHeader("User-Agent"); String HTTP_REFERER = request.getHeader("Referer"); HashMap infoMap = new HashMap(); infoMap.put("SERVER_NAME", SERVER_NAME); infoMap.put("SERVER_SOFTWARE", SERVER_SOFTWARE); infoMap.put("SERVER_PROTOCOL", SERVER_PROTOCOL); infoMap.put("SERVER_PORT", SERVER_PORT); infoMap.put("REQUEST_METHOD", REQUEST_METHOD); infoMap.put("PATH_INFO", PATH_INFO); infoMap.put("PATH_TRANSLATED", PATH_TRANSLATED); infoMap.put("SCRIPT_NAME", SCRIPT_NAME); infoMap.put("DOCUMENT_ROOT", DOCUMENT_ROOT); infoMap.put("QUERY_STRING", QUERY_STRING); infoMap.put("REMOTE_HOST", REMOTE_HOST); infoMap.put("REMOTE_ADDR", REMOTE_ADDR); infoMap.put("AUTH_TYPE", AUTH_TYPE); infoMap.put("REMOTE_USER", REMOTE_USER); infoMap.put("CONTENT_TYPE", CONTENT_TYPE); infoMap.put("CONTENT_LENGTH", CONTENT_LENGTH); infoMap.put("HTTP_ACCEPT", HTTP_ACCEPT); infoMap.put("HTTP_USER_AGENT", HTTP_USER_AGENT); infoMap.put("HTTP_REFERER", HTTP_REFERER); Iterator it = infoMap.keySet().iterator(); %> <% while (it.hasNext()) { Object o = it.next(); %> 　　<%=o%> 　　<%=infoMap.get(o)%> 　　<% out.println("
"); }%>
JSTL方式
${pageContext.request} |取得请求对象
${pageContext.session} |取得session对象
${pageContext.request.queryString} |取得请求的参数字符串
${pageContext.request.requestURL} |取得请求的URL，但不包括请求之参数字符串
${pageContext.request.contextPath} |服务的web application的名称
${pageContext.request.method} |取得HTTP的方法(GET、POST)
${pageContext.request.protocol} |取得使用的协议(HTTP/1.1、HTTP/1.0)
${pageContext.request.remoteUser} |取得用户名称
${pageContext.session.new} |判断session是否为新的，所谓新的session，表示刚由server产生而client尚未使用
${pageContext.session.id} |取得session的ID
${header["User-Agent"]}|用户浏览器的版本
${header["Host"]}|IP
${pageContext.request.remoteAddr } |取得用户的IP地址
${pageContext.servletContext.serverInfo}|取得主机端的服务信息
${pageContext.request.serverPort}|端口信息
${pageContext.request.serverName}|服务器名称
${pageContext.request.remoteHost}|客户机名称
