概念:
1、request.getRequestURL()
返回的是完整的url,包括Http协议,端口号,servlet名字和映射路径,但它不包含请求参数。
2、request.getRequestURI()
得到的是request URL的部分值,并且web容器没有decode过的
3、request.getContextPath()
返回 the context of the request.
4、request.getServletPath()
返回调用servlet的部分url.
5、request.getQueryString()
返回url路径后面的查询字符串
示例:
当前url:http://localhost:8080/CarsiLogCenter_new/idpstat.jsp?action=idp.sptopn
1.request.getRequestURL()
http://localhost:8080/CarsiLogCenter_new/idpstat.jsp
2.request.getRequestURI()
/CarsiLogCenter_new/idpstat.jsp
3.request.getContextPath()
/CarsiLogCenter_new
4.request.getServletPath()
/idpstat.jsp
5.request.getQueryString()
action=idp.sptopn
示例二:
1.
url:http://localhost:8080/Enterprise/EntUserServlet?action_flag=jumpReg
(1)httpRequest.getRequestURL()+"?" + httpRequest.getQueryString()
2.
http://localhost:8080/Enterprise/EntUserServlet?action_flag=jumpReg
(1)httpRequest.getRequestURI()+"?" + httpRequest.getQueryString()
/Enterprise/EntUserServlet?action_flag=jumpReg
(2)httpRequest.getServletPath()+"?" + httpRequest.getQueryString()
/EntUserServlet?action_flag=jumpReg
