Response-路径-相对路径
相对路径:通过相对路径不可以确定唯一资源
如:./index.html
不以/开头,以.开头路径
规则:找到当前资源和目标资源之间的相对位置关系
./:当前目录
../:后退一级目录.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>相对路径</h1> <h1>找到当前资源和目标资源之间的相对位置关系</h1> <P> 当前资源:location.html http://localhost/day15/location.html </P> <P> 目标资源: http://localhost/day15/responseDemo2 </P> <a href="./responseDemo2"> responseDemo2 </a> <a href="responseDemo2"> responseDemo2 </a> <br> <hr> <h1>绝对路径</h1> <a href="/day15/responseDemo2"> responseDemo2 </a> </body> </html>
Response-路径-绝对路径
绝对路径:通过绝对路径可以确定唯一资源
如:http://localhost/day15/responseDemo2 /day15/responseDemo2
以/开头的路径
规则:判断定义的路径是给谁用的?判断请求将来从哪儿发出
给客户端浏览器使用:需要加虚拟目录(项目的访问路径)
建议虚拟目录动态获取:request.getContextPath()
<a> , <form> 重定向...
给服务器使用:不需要加虚拟目录
转发路径
