[7.0.0] Spin up/down disks using /var/run/emhttpd.socket?

I had the below scripts in 6.12 to spin up/down disks from a command line. They no longer work in 7.0.0. Does anyone know what changes need to be made to get them working, or if there's an alternative in 7.0?

spinup() {
  . /usr/local/emhttp/state/var.ini
  curl --unix-socket /var/run/emhttpd.socket \
    --data-urlencode cmdSpinupAll=apply \
    --data-urlencode startState=$mdState \
    --data-urlencode csrf_token=$csrf_token \
    http://127.0.0.1/update
}
spindown() {
  . /usr/local/emhttp/state/var.ini
  curl --unix-socket /var/run/emhttpd.socket \
    --data-urlencode cmdSpindownAll=apply \
    --data-urlencode startState=$mdState \
    --data-urlencode csrf_token=$csrf_token \
    http://127.0.0.1/update
}
