Get current url in web application

Question

I am trying to grab the current url as it appears in the browser address bar on my JSP page and has several options to execute it.

• Using javax.servlet.include.request_uri and others defined in the Servlet 2.4 specification. I refer to this thread to get information about this java-httpservletrequest-get-url-in-browsers-url-bar .

In my current application, we are going to place a web server in front of our application server, than it seems that these values ​​will not be used.

I have another way to help javascript document.URL , but I'm not sure how reliable it will be.

I need to get information about the location of the user, and if I can use getRequestURI() , it will return something like getRequestURI() to me.

In short, all I want is to fix the URL in the address bar of the browser and save it in a hidden field of my JSP page.

I'm not sure the best way to achieve this.

Answer 1

If you want to use the javascript solution, you can use the window.document.location object and its properties:

 console.log(window.document.location.protocol); http: console.log(window.document.location.host); stackoverflow.com console.log(window.document.location.port); console.log(window.document.location.href); http://stackoverflow.com/questions/10845606/get-current-url-in-webapplication console.log(window.document.location.pathname); /questions/10845606/get-current-url-in-webapplication 

You can understand the other parameters reading this article in MDN.

In Java you can do this:

  public static String getCurrentUrl(HttpServletRequest request){ URL url = new URL(request.getRequestURL().toString()) String host = url.getHost(); String userInfo = url.getUserInfo(); String scheme = url.getProtocol(); String port = url.getPort(); String path = request.getAttribute("javax.servlet.forward.request_uri"); String query = request.getAttribute("javax.servlet.forward.query_string"); URI uri = new URI(scheme,userInfo,host,port,path,query,null) return uri.toString(); }

You can create a hidden field in your form

 <input type="hidden" id="myurl" name="myurl"/> 

then write javascript

 <script type="text/javascript"> document.getElementById('myurl').value = window.location.href </script> 

- is this help?
