Java Servlet API：从URL删除GET参数

Question

Is there anyway to remove the GET parameters from the request URL? Such that when the response arrives to the client, the window's location will be a URL clean from GET parameters. Is there anyway to do this without doing any redirects and that the parameters passed will be accessible on the server?

Thanks!

Purpose:
It is to shorten the URL. Currently in my site, links will have a handler that will convert GET parameters into hash parameters. After this, a location hash change listener will perform an AJAX request (with the location hash parameters) to reload certain parts of the document. When trying to open the links in new windows/tabs, I plan to "clean" the URL parameters and put it into the location hash, delimited by some string. If it is not possible to "clean" the URLs, it might become too long as there will be GET parameters and location hash parameters as well.

Answer 1

You could use a Servlet Filter with a HttpServletRequestWrapper .

In its doFilter method, you can impact on the Request .

Here is the official documentation on the Filter interface, and here is the page about HttpServletRequestWrapper .

Finally, here is an good SO page about what you want to do.

Answer 2

GET参数是URL编码的，这就是它的定义方式http://www.w3schools.com/tags/ref_httpmethods.asp可以使用几种编码方法，例如base64 ，但是如果有的话，也可以将其解码某些要安全发送到服务器的信息，您可以使用POST方法，也可以在web.xml映射您的页面，并添加带有身份验证检查的过滤器，以避免用户玩耍。

What is your intention for not having request parameters appear in the URL? If it's purely aesthetics then you could always use REST style urls - much like Stackoverflow - where the parameters are tokens within the URL.

Otherwise I don't believe it's possible for a client to request a certain URL?param1=.... and then end up with just URL without either a redirect from the server or the original request was a POST. Difference between POST and GET
