My problem is that I need to send a shutdown command to my NAS when the UPS tells my home server that there's a power cut. I want to do this by using the (Windows 10 Home) PC server's closedown notification, which can trigger a batch file as part of the closedown event, rather than by using extra hardware. I have determined that opening a particular URL will cause the NAS to close down gracefully.
The problems seem to be related to trying to bypass dialogues that result in the browser. First it asks for credentials. I can bypass this one by including them in the URL call, like this:
start "" "C:\Program Files\Mozilla Firefox\firefox.exe" "https://username:password@192.168.1.10/get_handler?PAGE=System&OUTER_TAB=tab_shutdown&INNER_TAB=NONE&shutdown_option1=1&command=poweroff&OPERATION=set"
Now it pops up a dialogue asking me to confirm that I want to log on as "username", again defeating my attempt to make this run unattended (I might be anywhere when a power cut strikes). Is there a way around this? Just FYI, I gave up trying to work with Microsoft Edge as it kept cutting the URL paramaeters into pieces by inserting spaces everywhere. It also kept manually complaining about the security certificate each and every time I tried it. I think I'll have the same confirmation request problems with that browser too. So I need a way to surpress all these dialogues and just make the URL call. Any thoughts please?
