io.vertx.rxjava.core.http

## Class HttpServerRequest

- java.lang.Object
- - io.vertx.rxjava.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.

    - #### bodyHandler

          public HttpServerRequest bodyHandler(Handler<Buffer> bodyHandler)

      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

          public NetSocket netSocket()

      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

    - #### setExpectMultipart

          public HttpServerRequest setExpectMultipart(boolean expect)

      Call this with true if you are expecting a multi-part body to be submitted in the request. This must be called before the body of the request has been received
      Parameters:
        `expect` - true - if you are expecting a multi-part body
      Returns:
        a reference to this, so the API can be used fluently

    - #### isExpectMultipart

          public boolean isExpectMultipart()

        true if we are expecting a multi-part body for this request. See `setExpectMultipart(boolean)`.

    - #### uploadHandler

          public HttpServerRequest uploadHandler(Handler<HttpServerFileUpload> uploadHandler)

      Set an upload handler. The handler will get notified once a new file upload was received to allow you to deal with the file upload.
      Parameters:
        `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.

      Be aware that the attributes will only be available after the whole body has been received, i.e. after the request end handler has been called.

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

      Returns:
        the form attributes

    - #### getFormAttribute

          public String getFormAttribute(String attributeName)

      Return the first form attribute value with the specified name
      Parameters:
        `attributeName` - the attribute name
      Returns:
        the attribute value

    - #### upgrade

          public ServerWebSocket upgrade()

      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

          public HttpServerRequest customFrameHandler(Handler<HttpFrame> handler)

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

    - #### connection
