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
