Inyecting data from the server to a label in a session by id

[DonaldShimoda]

Imagine i have 5 sessions open. Each session have one id stored in a cookie.

I need to change a label dinamically, from the server, in the correct session id.

Example, update temperature value in session with id 1

Is possible? Any hint how to search the session id?

How will refresh at client side(browser)

Best regards

I use this to close all active sessions from one user (by name) without my own.

 

unisession

var

sUserName : String;

 

 

procedure CloseOtherSesionsFromUser (sesionUser : AnsiString);
var
I : Integer;
U : TUniGUISession;
begin
Try
  UniServerModule.SessionManager.Sessions.Lock;
  for I :=UniServerModule.SessionManager.Sessions.SessionList.Count - 1 downto 0 do begin
      U := UniServerModule.SessionManager.Sessions.SessionList[I];
      //U.LockSession;
      // Check mainModule availability. Some sessions may not have a MainModule instance
      if U.UniMainModule <> nil then begin
        // Do not close my OWN Session
        if (UniApplication.UniSession.SessionID <> U.SessionId)
        AND ((U.UniMainModule as TUniMainModule).sUserName = sesionUser)
        then begin
           U.ReleaseSession;
           U.Terminate ('Already connected: ' + sesionUser + '.'
                        + '</br>' + 'Session is closed');
        end;
         // UniMainModule(U.UniMainModule as TUniMainModule).logout ((U.UniMainModule as TUniMainModule).sUsername); // Access custom MainModule props
      end;
  end;
  UniServerModule.SessionManager.Sessions.Unlock;
Finally

End;
end;

 

You can use sessions list, to search active session.

 

I use other function to search components by extended FindComponent in screen.activeform and change the values

Web Sockets will be perfect solution for you.

We already use this tech. in our web app for chat.

I'll see if there is spare time for creating a video tutorial for Unigui + WebScokets (real time app) 🙂
