Package io.vertx.rxjava3.core.http

## Class HttpServer

- java.lang.Object
- - io.vertx.rxjava3.core.http.HttpServer

- All Implemented Interfaces:
    `io.vertx.lang.rx.RxDelegate`, `Measured`

      public class HttpServer
      extends Object
      implements io.vertx.lang.rx.RxDelegate, Measured

  An HTTP and WebSockets server.

  You receive HTTP requests by providing a `requestHandler(io.vertx.core.Handler<io.vertx.rxjava3.core.http.HttpServerRequest>)`. As requests arrive on the server the handler will be called with the requests.

  You receive WebSockets by providing a `webSocketHandler(io.vertx.core.Handler<io.vertx.rxjava3.core.http.ServerWebSocket>)`. As WebSocket connections arrive on the server, the WebSocket is passed to the handler.

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

    - #### requestHandler

          public HttpServer requestHandler​(Handler<HttpServerRequest> handler)

      Set the request handler for the server to `requestHandler`. As HTTP requests are received by the server, instances of `HttpServerRequest` will be created and passed to this handler.
      Parameters:
        `handler` -
      Returns:
        a reference to this, so the API can be used fluently

    - #### invalidRequestHandler

          public HttpServer invalidRequestHandler​(Handler<HttpServerRequest> handler)

      Set a `handler` for handling invalid requests. When an invalid request is received by the server this handler will be called with the request. The handler can send any HTTP response, when the response ends, the server shall close the connection. `io.vertx.rxjava3.core.http.HttpServerRequest#decoderResult` can be used to obtain the Netty decoder result and the failure cause reported by the decoder.

      Currently this handler is only used for HTTP/1.x requests.

      When no specific handler is set, the `HttpServerRequest` is used.

      Parameters:
        `handler` -
      Returns:
        a reference to this, so the API can be used fluently

    - #### connectionHandler

          public HttpServer connectionHandler​(Handler<HttpConnection> handler)

      Set a connection handler for the server.
      The handler will always be called on the event-loop thread.
      Parameters:
        `handler` -
      Returns:
        a reference to this, so the API can be used fluently

    - #### webSocketHandshakeHandler

          public HttpServer webSocketHandshakeHandler​(Handler<ServerWebSocketHandshake> handler)

      Set a handler for WebSocket handshake.

      When an inbound HTTP request presents a WebSocket upgrade, this handler is called first. The handler can chose to `ServerWebSocketHandshake.accept()` or `ServerWebSocketHandshake.reject()` the request.

      Setting no handler, implicitly accepts any HTTP request connection presenting an upgrade header and upgrades it to a WebSocket.

      Parameters:
        `handler` -
      Returns:

    - #### exceptionHandler

          public HttpServer exceptionHandler​(Handler<Throwable> handler)

      Parameters:
        `handler` - the handler to set
      Returns:
        a reference to this, so the API can be used fluently

    - #### webSocketHandler

          public HttpServer webSocketHandler​(Handler<ServerWebSocket> handler)

      Set the WebSocket handler for the server to `wsHandler`. If a WebSocket connect handshake is successful a new `ServerWebSocket` instance will be created and passed to the handler.
      Parameters:
        `handler` -
      Returns:
        a reference to this, so the API can be used fluently

        a future signaling the update success

    - #### rxUpdateSSLOptions
