TsgcWebSocketClient | Client Exceptions

Sometimes there are errors in communications: the server can disconnect a connection because it is not authorized or a message does not have the correct format. There are 2 events where errors are captured.

OnError

This event is fired every time there is an error in WebSocket protocol, like invalid message type, invalid utf8 string...

procedure OnError(Connection: TsgcWSConnection; const Error: string);
begin
  WriteLn('#error: ' + Error);
end;

OnException

This event is fired every time there is an exception, such as writing to a socket that is not active or accessing an object that does not exist.

procedure OnException(Connection: TsgcWSConnection; E: Exception);
begin
  WriteLn('#exception: ' + E.Message);
end;

By default, when a connection is closed by the server, an exception will be fired. If you do not want these exceptions to be fired, disable Options.RaiseDisconnectExceptions.
