getRequestURI()与getRequestURL()

引于: http://hi.baidu.com/cloudxpc

 

 

request.getRequestURI() 返回值类似：/xuejava/requestdemo.jsp

request.getRequestURL() 返回值类似：http://localhost:8080/xuejava/requestdemo.jsp

 

附：

request.getContextPath() = /hboys
request.getLocalAddr() = 127.0.0.1
request.getPathInfo() = null
request.getPathTranslated() = null
request.getRemoteAddr() = 127.0.0.1
request.getRequestURI() = /hboys/
request.getScheme() = http
request.getServerName() = 127.0.0.1
request.getServletPath() = /index.jsp
request.getClass() = class org.apache.catalina.connector.RequestFacade
request.getHeaderNames() = 
request.getLocale() = zh_CN
request.getLocales() = 
request.getParameterMap() = {}
request.getRequestURL() = http://127.0.0.1:8081/hboys/
request.getUserPrincipal() = null
request.getParameterNames() = 
request.getRealPath("newsPub") = D:\workspace\hboys\WebRoot\newsPub

 

假定你的web application 名称为news,你在浏览器中输入请求路径：

http://localhost:8080/news/main/list.jsp

则执行下面向行代码后打印出如下结果：

1、 System.out.println(request.getContextPath());

打印结果：/news
   2、System.out.println(request.getServletPath());

打印结果：/main/list.jsp
3、 System.out.println(request.getRequestURI());

打印结果：/news/main/list.jsp
4、 System.out.println(request.getRealPath("/"));

打印结果：F:\Tomcat 6.0\webapps\news\test
