PrusaConnect camera with raspberry pi + curl
I'm trying to use this thread as a reference together with the prusa connect camera api reference and to register a camera with curl, but keep getting
{"message": "Missing or invalid security token", "code": "UNAUTHORIZED"}
My request:
curl -X POST \ -H "token: <token from https://connect.prusa3d.com/printer/<my printer uuid>/cameras>" \ -H "fingerprint: <name of the camera in https://connect.prusa3d.com/printer/<my printer uuid>/cameras>" \ https://connect.prusa3d.com/app/printers/<my printer uuid/camera?origin=OTHER
I think I just didn't understand what the token and fingerprint are. These are given here right? I guess the fingerprint is the camera name, and the token is what is given here.
Can you see what I am doing wrong here?

never mind, the service seems to be down at the moment...
{"message": "Service is unavailable at this moment. Try again later", "code": "SERVICE_UNAVAILABLE"}

I got it to work. The TOKEN is not the same as the QR code it seems, you have to grab that as well from the web app. Here is some code to make it work with rpicam-still:
#!/usr/bin/env bash
set -Eeu
set -o pipefail
shopt -s extdebug
FINGERPRINT="changeme"
TOKEN="changeme"
trap 'declare rc=$?;
>&2 echo "Unexpected error (exit-code $rc) executing $BASH_COMMAND at ${BASH_SOURCE[0]} line $LINENO";
exit $rc' ERR
main () {
while true
do
if rpicam-still -t 1 -o - \
| curl https://webcam.connect.prusa3d.com/c/snapshot \
-X PUT \
-L --fail-with-body \
-H "Content-Type: image/jpg" \
-H "Fingerprint: $FINGERPRINT" \
-H "Token: $TOKEN" \
--data-binary @-
then
printf "."
else
echo
echo "?"
fi
sleep 30
done
}
main "$@"

Just adding here that the camera fingerprint seems to be a generated UUID. `uuidgen` in your shell, or any uuid generator should be able to create one. no need to go through the prusa QR flow.
