B4J Question B4J server, receive parameter from url

[Mostez]

I use attached html page to confirm if night drive trip is required (at client side) the page url is sent to client by email for confirmation, like:

http://127.0.0.1:17178/nightdrive/?

ordernum=12345
I want to receive the ordernum parameter (12345 from link) at server side and put in Order Number text box to handle it as required

How to do that?

TIA

Check the content of the request-Object.

Sub Handle(req As ServletRequest, resp As ServletResponse)
    req.GetSession.RemoveAttribute("myNumber")
    Dim attribs As Map = req.ParameterMap
    
    For Each key As String In attribs.Keys
        Log($"Key ${key} = ${attribs.Get(key)}"$)
    Next
    'Log(req.GetSession)
End Sub

I start the session like this : http://127.0.0.1:17178/nightdrive/?ordernum=12345

this code returns null

Private Sub WebSocket_Connected (WebSocket1 As WebSocket)
    ws = WebSocket1
    Log(ws.Session.GetAttribute("ordernum"))   
End Sub

this code returns null

recheck my post above..... Note that i am using a serverhandler here

Your URL and event handler do not correspond, it seems. (A call to an HTTP URL does not trigger a websocket event handler.)

I start the session like this : http://127.0.0.1:17178/nightdrive/?ordernum=12345

this code returns null

Private Sub WebSocket_Connected (WebSocket1 As WebSocket)
    ws = WebSocket1
    Log(ws.Session.GetAttribute("ordernum"))   
End Sub

You either need to make a websocket call (ws://127.0.0.1:17178/nightdrive/?ordernum=12345) or use a server handler (as @DonManfred said).
