Class HttpServerRequest

java.lang.Object
io.vertx.rxjava3.core.http.HttpRequestHead
io.vertx.rxjava3.core.http.HttpServerRequest
All Implemented Interfaces:
io.vertx.lang.rx.RxDelegate, ReadStream<Buffer>, StreamBase
public class HttpServerRequest extends HttpRequestHead implements io.vertx.lang.rx.RxDelegate, ReadStream<Buffer>
Represents a server-side HTTP request.

Instances are created for each request and passed to the user via a handler.

Each instance of this class is associated with a corresponding HttpServerResponse instance via response().

It implements ReadStream so it can be used with Pipe to pipe data with flow control.

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

      If you need to do an asynchronous upgrade, i.e not performed immediately in your request handler, you need to pause() the request in order to not lose HTTP events necessary to upgrade the request.

      Returns:
      a future notified with the upgraded WebSocket

    • rxToWebSocket

      public Single<ServerWebSocket> rxToWebSocket()
      Upgrade the connection of the current request to a WebSocket.

      Both handler(Handler) and endHandler(Handler) will be set to get the full body of the request that is necessary to perform the WebSocket handshake.

      If you need to do an asynchronous upgrade, i.e not performed immediately in your request handler, you need to pause() the request in order to not lose HTTP events necessary to upgrade the request.

    • cookies

      public Set<Cookie> cookies(String name)

A cookie is unique by its invalid input: '<'name, domain, path> tuple. The set entries are references to the request original set. This means that performing property changes in the cookie objects will affect the original object too. NOTE: the returned is read-only. This means any attempt to modify (add or remove to the set), will throw UnsupportedOperationException.
      Parameters:
      name - the name to be matches
      Returns:
      the matching cookies or empty set

A cookie is unique by its invalid input: '<'name, domain, path> tuple. Request cookies are directly linked to response cookies. Any modification to a cookie object in the returned set will mark the cookie to be included in the HTTP response. Removing a cookie from the set, will also mean that it will be removed from the response, regardless if it was modified or not.
      Returns:
      a set with all cookies in the cookie jar.
