Get URL of the request sender with HttpServletRequest

问题

How do you get the source domain using HttpServletRequest? Source domain is the requester's domain.

Thanks.

回答1:

You could do either

// gets client (browser)'s hostname
String host = request.getRemoteHost(); 

OR

// get the server's domain name.
String domain = new URL(request.getRequestURL().toString()).getHost(); 

回答2:

Hostname request

InetAddress ip = InetAddress.getLocalHost();
String hostname = ip.getHostName();
out.print("Your current IP address : " + ip+"\n");
out.print("Your current Hostname : " + hostname);
