Analysis of the method of obtaining url path from jsp

This article illustrates how jsp gets the path of url. Share it for your reference, as follows:

If the URL you requested is http://localhost: 8080/demo/Index. jsp

request.getScheme()  // Output: http

request.getServerName()  // Output:  localhost

request.getServerPort() // Output:  8080

request.getContextPath()  // Output:  /demo

request.getRequestPath() // Output:  /Index.jsp

request.gerRequestURI() // Output:   /demo/Index.jsp

request.getRequestURL() // Output:  http://localhost:8080/demo/Index.jsp

request.getRealPath("") // Output: D:\apache-tomcat-6.0.10\webapps\demo

I have verified all the above, except that request. getRequestPath () can't be used (it is estimated that this function has been discarded), and other displays are correct.

I hope this article is helpful to everyone's JSP programming.
