How to get type of platform on UniGUIServerModuleHTTPCommand

[irigsoft]

Hello, I try to get UniApplication.UniPlatform on UniGUIServerModuleHTTPCommand, when user start Session, but I get "Access violation at address".

Is it possible to get this information from something else like ExtractSessionId(ARequestInfo.UnParsedParams)?

I have write some restrictions if Platform is Android or IPhone and I need to know this when Session Start.

Hello @irigsoft

Can you try also this approach?

procedure TUniServerModule.UniGUIServerModuleHTTPCommand(
  ARequestInfo: TIdHTTPRequestInfo; AResponseInfo: TIdHTTPResponseInfo;
  var Handled: Boolean);
  function getOSName(AUserAgent: string): string;
  begin
    if AUserAgent = '' then
    begin
      Result := 'Unknown OS';
      Exit;
    end;

    AUserAgent := LowerCase(AUserAgent);

    if Pos('win', AUserAgent) > 0 then Result := 'Windows'
    else if Pos('mac', AUserAgent) > 0 then Result := 'Macintoch'
    else if Pos('linux', AUserAgent) > 0 then Result := 'Linux'
    else if Pos('android', AUserAgent) > 0 then Result := 'Android'
    else if Pos('like Mac', AUserAgent) > 0 then Result := 'iOS'
    else Result := 'Unknown OS';
  end;
begin
  // getOSName(ARequestInfo.UserAgent)
end;

thanks, my problem is (how to check if navigator.connection is supported from browser of user ?):

I want to use this code on all devices Android and Iphone (but Safari not support navigator)

function window.afterrender ( .......

//  if (window?.navigator?.connection) { //- this work on IPhone + Safary, but not work on Android 5 + Google Chrome

// this work only on Android
        var connection = navigator.connection || navigator.mozConnection || navigator.webkitConnection;
        //alert (navigator.connection);
        
        var type = connection.effectiveType;
        
        function updateConnectionStatus() {
              
                 //console.log("Connection type changed from " + type + " to " + connection.effectiveType);
                 type = connection.type || connection.effectiveType;
                 ajaxRequest(sender, "connectionType", ["ctype="+type]);
        };

        updateConnectionStatus();
        connection.addEventListener('change', updateConnectionStatus);
//  }
//   else {
//     var type = "None";
//     ajaxRequest(sender, "connectionType", ["ctype="+type]);
//   }

//  }
//   else {
//     var type = "None";
//     ajaxRequest(sender, "connectionType", ["ctype="+type]);
//   }

Thanks again, I correct my code to and now it's work :

from: //  if (window?.navigator?.connection) { //- this work on IPhone + Safary, but not work on Android 5 + Google Chrome

to :

  if (window.navigator && window.navigator.connection) { //- this work on IPhone + Safary + Android + Google Chrome

... my code from above

};

 

I will use information from userAgent for some of my functions.
