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

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
