Hi, All

How to get form parameters ? Why method is wrongly got ?
What's wrong with the code ?
It's plain HTML generated page, without JS (that is unknown for me), just single handler:
B4X:
srvr.AddHandler("/grabber_settings", "grabber_settings", False)
Single handler app::
Sub Handle(req As ServletRequest, resp As ServletResponse)
Try
Log(CRLF & "------------" & CRLF & "Method: " & req.Method)
Log("ContentType: " & req.ContentType)
Log(req.GetSession.GetAttributesNames)
Dim Params As Map = req.ParameterMap
Log(Params)
Dim new_url As String = req.GetParameter("RTSP_URL")
If new_url <> "" Then
Main.Grabbing = False
Main.RTSP_URL = new_url
End If
If Params.ContainsKey("btnStart") Then
Main.Grabbing = True
End If
If Params.ContainsKey("btnStop") Then
Main.Grabbing = False
End If
resp.Write("<html><body><form method='POST' action='grabber_settings'>")
Dim rtsp_form As String = $"Source IP-camera RTSP address: <input type="text" id="RTSP_URL" size = "50" value = "$ & Main.RTSP_URL & "></input>"
rtsp_form = rtsp_form & $"<button type="Submit">Save URL</button><br>"$
resp.Write(rtsp_form)
resp.Write("<br>").Write("Grabbing service: " & (IIf(Main.Grabbing, $"<button type="Submit" id="btnStop">STOP</button>"$, _
$"<button type="Submit" id="btnStart">START !</button>"$)))
resp.Write("</form></body></html>")
Catch
resp.SendError(500, "Server internal error")
End Try
