I'm trying to get the windows user name of the user in my web application. Can any one suggest how to get it?
I'm developing a web application. So if a user is accessing my application, then I need to get the user's windows id and his host name. I tried a few different ways but it never worked. Any suggestions are highly appreciated.
回答1:
Windows user details are not sent in plain HTTP requests, which makes it impossible for you to derive them from a user in a web application without additional data. The host name from which the request is sent is available in the request headers, though.
If you'd still like to get Windows user details, you'll have to do some work, like ask the user to provide them in some form, or, if you have access to the user's Naming/Directory service, you can find things out through his IP/hostname. This is something you generally don't have readily available in web applications, though.

In YERY OLD(!) version of Internet Explorer the pattern %USER% inside of a URL was replaced by the login username. But with current browsers this doesn't work anymore, and that's good that way.
With JAVA applet you can request it via:
System.getProperty("user.name")
But I don't know if this works for you...

And it seems to be intentionally impossible in common case with modern browsers:
