WebSocketUpgrade

trait WebSocketUpgrade extends javadsl.model.ws.WebSocketUpgrade

An attribute that will be added to an WebSocket upgrade HttpRequest that enables a request handler to upgrade this connection to a WebSocket connection and registers a WebSocket handler.

This is a low-level API. You might want to use handleWebSocketMessages instead as documented at https://doc.akka.io/libraries/akka-http/current/server-side/websocket-support.html#routing-support

Abstract Value Members

  1. abstract def handleMessages(handlerFlow: Graph[FlowShape[Message, Message], Any], subprotocol: Option[String] = None): HttpResponse

    The high-level interface to create a WebSocket server based on "messages".

    The high-level interface to create a WebSocket server based on "messages".

    Returns a response to return in a request handler that will signal the low-level HTTP implementation to upgrade the connection to WebSocket and use the supplied handler to handle incoming WebSocket messages.

    Optionally, a subprotocol out of the ones requested by the client can be chosen.

  2. abstract def requestedProtocols: Seq[String]

    A sequence of protocols the client accepts.

    The high-level interface to create a WebSocket server based on "messages".

    Returns a response to return in a request handler that will signal the low-level HTTP implementation to upgrade the connection to WebSocket and use the supplied inSink to consume messages received from the client and the supplied outSource to produce message to sent to the client.

    Optionally, a subprotocol out of the ones requested by the client can be chosen.
