Class CSRFHandler

java.lang.Object

io.vertx.rxjava3.ext.web.handler.CSRFHandler

All Implemented Interfaces:

Handler<RoutingContext>

public class CSRFHandler
extends Object
implements Handler<RoutingContext>

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.

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