trait AuthHandler extends Handler[RoutingContext]

Base interface for auth handlers.

An auth handler allows your application to provide authentication/authorization support.

Auth handler requires a io.vertx.scala.ext.web.handler.SessionHandler to be on the routing chain before it.

class BasicAuthHandler extends AuthHandler with Handler[RoutingContext]

An auth handler that provides HTTP Basic Authentication support.

class BodyHandler extends Handler[RoutingContext]

A handler which gathers the entire request body and sets it on the .

It also handles HTTP file uploads and can be used to limit body sizes.

class CSRFHandler extends Handler[RoutingContext]

This handler adds a CSRF token to requests which mutate state.

This handler adds a CSRF token to requests which mutate state. In order change the state a (XSRF-TOKEN) cookie is set with a unique token, that is expected to be sent back in a (X-XSRF-TOKEN) header.

The behavior is to check the request body header and cookie for validity.

This Handler requires session support, thus should be added somewhere below Session and Body handlers.

class ChainAuthHandler extends AuthHandler with Handler[RoutingContext]

An auth handler that chains to a sequence of handlers.

class CookieHandler extends Handler[RoutingContext]

A handler which decodes cookies from the request, makes them available in the and writes them back in the response.

class CorsHandler extends Handler[RoutingContext]

A handler which implements server side http://www.w3.org/TR/cors/[CORS] support for Vert.x-Web.

class DigestAuthHandler extends AuthHandler with Handler[RoutingContext]

An auth handler that provides HTTP Basic Authentication support.

class ErrorHandler extends Handler[RoutingContext]

A pretty error handler for rendering error pages.

class FaviconHandler extends Handler[RoutingContext]

A handler that serves favicons.

If no file system path is specified it will attempt to serve a resource called favicon.ico from the classpath.

class FormLoginHandler extends Handler[RoutingContext]

Handler that handles login from a form on a custom login page.

Used in conjunction with the io.vertx.scala.ext.web.handler.RedirectAuthHandler.

class JWTAuthHandler extends AuthHandler with Handler[RoutingContext]

class LoggerHandler extends Handler[RoutingContext]

class ResponseContentTypeHandler extends Handler[RoutingContext]

A handler which sets the response content type automatically according to the best Accept header match.

The header is set only if:

no object is stored in the routing context under the name io.vertx.scala.ext.web.handler.ResponseContentTypeHandler
a match is found
the header is not present already
content length header is absent or set to something different than zero

class ResponseTimeHandler extends Handler[RoutingContext]

Handler which adds a header x-response-time in the response of matching requests containing the time taken in ms to process the request.

class SessionHandler extends Handler[RoutingContext]

A handler that maintains a io.vertx.scala.ext.web.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 .

The session handler requires a io.vertx.scala.ext.web.handler.CookieHandler to be on the routing chain before it.

class StaticHandler extends Handler[RoutingContext]

class TemplateHandler extends Handler[RoutingContext]

A handler which renders responses using a template engine and where the template name is selected from the URI path.
