## Class HttpServerRequest

- java.lang.Object
- - io.vertx.reactivex.core.http.HttpServerRequest

- All Implemented Interfaces:
    ReadStream<Buffer>, StreamBase

      public class HttpServerRequest
      extends Object
      implements 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 `Pump` to pump data with flow control.

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

      Convenience method for receiving the entire request body in one piece.

      This saves the user having to manually setting a data and end handler and append the chunks of the body until the whole body received. Don't use this if your request body is large - you could potentially run out of RAM.

      Parameters:
        `bodyHandler` - This handler will be called after all the body has been received
      Returns:

    - #### netSocket

          @Deprecated
          public NetSocket netSocket()

      Deprecated.
      Get a net socket for the underlying connection of this request.

      This method must be called before the server response is ended.

      With `CONNECT` requests, a `200` response is sent with no `content-length` header set before returning the socket.

           server.requestHandler(req -> {
             if (req.method() == HttpMethod.CONNECT) {
               // Send a 200 response to accept the connect
               NetSocket socket = req.netSocket();
               socket.handler(buff -> {
                 socket.write(buff);
               });
             }
             ...
           });

      For other HTTP/1 requests once you have called this method, you must handle writing to the connection yourself using the net socket, the server request instance will no longer be usable as normal. USE THIS WITH CAUTION! Writing to the socket directly if you don't know what you're doing can easily break the HTTP protocol.

      With HTTP/2, a `200` response is always sent with no `content-length` header set before returning the socket like in the `CONNECT` case above.

      Returns:
        the net socket

    - #### toNetSocket

          public void toNetSocket(Handler<AsyncResult<NetSocket>> handler)

      Establish a TCP tunnel with the client.

      This must be called only for `CONNECT` HTTP method and before any response is sent.

      Calling this sends a `200` response with no `content-length` header set and then provides the `NetSocket` for handling the created tunnel. Any HTTP header set on the response before calling this method will be sent.

           server.requestHandler(req -> {
             if (req.method() == HttpMethod.CONNECT) {
               // Send a 200 response to accept the connect
               NetSocket socket = req.netSocket();
               socket.handler(buff -> {
                 socket.write(buff);
               });
             }
             ...
           });

      Parameters:
        `handler` - the completion handler

    - #### rxToNetSocket

          public Single<NetSocket> rxToNetSocket()

      Establish a TCP tunnel with the client.

      This must be called only for `CONNECT` HTTP method and before any response is sent.

      Calling this sends a `200` response with no `content-length` header set and then provides the `NetSocket` for handling the created tunnel. Any HTTP header set on the response before calling this method will be sent.

           server.requestHandler(req -> {
             if (req.method() == HttpMethod.CONNECT) {
               // Send a 200 response to accept the connect
               NetSocket socket = req.netSocket();
               socket.handler(buff -> {
                 socket.write(buff);
               });
             }
             ...

      Returns:

    - #### setExpectMultipart

          public HttpServerRequest setExpectMultipart(boolean expect)

        a reference to this, so the API can be used fluently

    - #### isExpectMultipart

          public boolean isExpectMultipart()

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

    - #### formAttributes

          public MultiMap formAttributes()

      Returns a map of all form attributes in the request.

      `setExpectMultipart(boolean)` must be called first before trying to get the form attributes.

      Returns:
        the form attributes

    - #### upgrade

          @Deprecated
          public ServerWebSocket upgrade()

      Deprecated.
      Upgrade the connection to a WebSocket connection.

      This is an alternative way of handling WebSockets and can only be used if no WebSocket handler is set on the `HttpServer`, and can only be used during the upgrade request during the WebSocket handshake.

      Returns:
        the WebSocket

    - #### toWebSocket

          public void toWebSocket(Handler<AsyncResult<ServerWebSocket>> handler)

      Upgrade the connection of the current request to a WebSocket.

      This is an alternative way of handling WebSockets and can only be used if no WebSocket handler is set on the `HttpServer`, and can only be used during the upgrade request during the WebSocket handshake.

      Both `handler(io.vertx.core.Handler<io.vertx.reactivex.core.buffer.Buffer>)` and `endHandler(io.vertx.core.Handler<java.lang.Void>)` 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.

      Parameters:
        `handler` - the completion handler

    - #### rxToWebSocket

          public Single<ServerWebSocket> rxToWebSocket()

      Upgrade the connection of the current request to a WebSocket.

      This is an alternative way of handling WebSockets and can only be used if no WebSocket handler is set on the `HttpServer`, and can only be used during the upgrade request during the WebSocket handshake.

      Both `handler(io.vertx.core.Handler<io.vertx.reactivex.core.buffer.Buffer>)` and `endHandler(io.vertx.core.Handler<java.lang.Void>)` 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.

      Returns:

    - #### isEnded
