websocket_server_check_handshake


Description:


public bool websocket_server_check_handshake (ServerMessage msg, string? origin, string[]? protocols, GenericArray<TypeClass>? supported_extensions) throws Error

Examines the method and request headers in msg and determines whether msg contains a valid handshake request.

If origin is non-null, then only requests containing a matching "Origin" header will be accepted. If protocols is non-null, then only requests containing a compatible "Sec-WebSocket-Protocols" header will be accepted. If supported_extensions is non-null, then only requests containing valid supported extensions in "Sec-WebSocket-Extensions" header will be accepted.

Normally [func@websocket_server_process_handshake] will take care of this for you, and if you use [method@Server.add_websocket_handler] to handle accepting WebSocket connections, it will call that for you. However, this function may be useful if you need to perform more complicated validation; eg, accepting multiple different Origins, or handling different protocols depending on the path.

Parameters:

msg

ServerMessage containing the client side of a WebSocket handshake

origin

expected Origin header

protocols

allowed WebSocket protocols.

supported_extensions

list of supported extension types

Returns:

true if msg contained a valid WebSocket handshake, false and an error if not.
