TsgcWebSocketClient › Proprietà › Options
Personalizza le intestazioni dell'handshake e perfeziona il comportamento del client, come la frammentazione e la validazione UTF-8.
property Options: TsgcWSOptionsClient read FOptions write SetOptions;FragmentedMessages=frgOnlyBuffer, RaiseDisconnectExceptions=True, ValidateUTF8=False, CleanDisconnect=False, WaitForConnect=False
Espone le impostazioni di handshake e runtime: Parameters (parametri GET aggiuntivi), Origin (intestazione Origin personalizzata) e FragmentedMessages che seleziona se i frammenti vengono bufferizzati (frgOnlyBuffer), segnalati singolarmente (frgOnlyFragmented) o entrambi (frgAll). RaiseDisconnectExceptions genera un'eccezione sulle disconnessioni per errori di protocollo, ValidateUTF8 verifica la conformità UTF-8 dei frame di testo e CleanDisconnect invia un frame di chiusura prima di terminare la sessione TCP.
WaitForConnect controls when the synchronous Connect call returns. By default (False) Connect returns as soon as the WebSocket transport is connected, which can be before the OnConnect event has fired. When set to True, Connect returns only after the OnConnect event has run, so for a sub-protocol that establishes a session on connect (for example the sgc protocol, which assigns a session in its OnConnect) the connection is fully ready as soon as Connect returns. This avoids a connect-readiness race on fast reconnects, where code that inspects the connection immediately after Connect could run before the sub-protocol OnConnect had fired. It applies when NotifyEvents is neNoSync, where events run inline on the read thread. With neAsynchronous the OnConnect event is queued to the main thread and cannot be awaited inside Connect, so use the OnConnect event to detect readiness in that case.
