如何在REST应用程序中获取“ X-Forwarded-Proto”标头？

Question

I have a REST application running on tomcat. I am forwarding http requests to https using server.xml redirectPort parameter.

Now, on the server side, I want to read the X-Forwarded-Proto header to identify if requests are being redirected.

My code looks like this:

@Context
UriInfo uriInfo;

@Context
Request request;

protected Response checkRedirect(SecurityContext sc)
{

   String forwardedProtocol = ((ContainerRequest)request).getHeaderValue("X-Forwarded-Proto");

}

However, this does not work. It seems like the request object only gives access to handful of http headers.

Can someone please suggest the best way I can obtain the header value? Thanks in advance.

您需要指示 tomcat注意。
