websocket_server_check_handshake_with_extensions
Description:
[ Version ( since = "2.68" ) ]
public bool websocket_server_check_handshake_with_extensions (Message 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 soup_websocket_server_process_handshake_with_extensioins will take care of this for you, and if you use
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 |
Message containing the client side of a WebSocket handshake |
| origin |
expected Origin header |
| protocols |
allowed WebSocket protocols. |
| supported_extensions |
list of supported extension types |
Returns:
|
