Package io.vertx.reactivex.ext.web.handler

Class SessionHandler

  • All Implemented Interfaces:
    Handler<RoutingContext>, PlatformHandler
    public class SessionHandler
extends Object
implements PlatformHandler, Handler<RoutingContext>
    A handler that maintains a Session for each browser session.

    It looks up the session for each request based on a session cookie which contains a session ID. It stores the session when the response is ended in the session store.

    The session is available on the routing context with .

    NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

        Parameters:
        cookieMaxAge - a non negative max-age, note that 0 means expire now.

        Parameters:
        ctx - the current context
        Returns:
        a future signaled with the asynchronous response.

      • setSigningSecret

        public SessionHandler setSigningSecret​(String secret)
        Set signing secret for the session cookie. The cookie will not be signed and verified by the SessionHandler if this is not set. But may be signed by the session implementation, for example, CookieSessionStore signs the cookie data.
