一.获取请求参数通用方式 1. String getParameter(String name):根据参数名称获取参数值 例:username=flypig&password=2343 2. String[] getParameterValues(String name):根据参数名称获取参数值的数组 例:hooby=xx&hobby=name 3. Enumeration<String> getParameterNames():获取所有请求的参数名称 4. Map<St

request概述(封装了客户端所有的请求数据) request是Servlet.service()方法的一个参数,类型为javax.servlet.http.HttpServletRequest.在客户端发出每个请求时,服务器都会创建一个request对象,并把请求数据封装到request中,然后在调用Servlet.service()方法时传递给service()方法,这说明在service()方法中可以通过request对象来获取请求数据.request对象的创建:request是由tom

从Request对象中可以获取各种路径信息,以下例子: 假设请求的页面是index.jsp,项目是WebDemo,则在index.jsp中获取有关request对象的各种路径信息如下 String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+&q

1.获取请求host StringBuffer url = request.getRequestURL(); String tempContextUrl = url.delete(url.length() - request.getRequestURI().length(), url.length()).toString(); 2.获取静态页的相对路径 String path=request.getSession().getServletContext().getRealPath("相对路径&q

Request.url请求路径的一些属性1,Request.UrlReferrer.AbsolutePath=获取URL的绝对路径例:"/Manager/Module/OfficialManage/Issuedadocument/Issuedadocument_WorkNew.aspx" 2,Request.UrlReferrer.AbsoluteUri=获取绝对URL例:"http://localhost:2855/Manager/Module/OfficialManage

1 request对象常用API   1)表示web浏览器向web服务端的请求   2)url表示访问web应用的完整路径:http://localhost:8080/day06/Demo1     uri表示访问web应用的资源路径:/day06/Demo1     queryString表示?开头的参数;name=jack     pathInfo:路径之外的信息,如果没有,返回null package cn.itcast.web.request; import java.io.IOExce
