Interface UpgradeToWebSocket

All Superinterfaces:
WebSocketUpgrade
All Known Subinterfaces:
UpgradeToWebSocket
All Known Implementing Classes:
UpgradeToWebSocketLowLevel
public interface UpgradeToWebSocket extends WebSocketUpgrade
Deprecated.
use the WebSocketUpgrade attribute instead since 10.2.0
A virtual header that WebSocket requests will contain. Use UpgradeToWebSocket.handleMessagesWith to create a WebSocket handshake response and handle the WebSocket message stream with the given handler.

This low-level API is expected to be replaced by an Attribute in the future.

In any case, you might want to use handleWebSocketMessages instead as documented at https://doc.akka.io/docs/akka-http/current/server-side/websocket-support.html#routing-support
