Ultimaker S5 API authentication problem

[JurgenMK 0]

Hello,

I have a question about the rest API,

When I try to authenticate using a key and id I got from /auth/request,

It always returns the 401 authentication required, no matter where I enter it on postman.

does anyone know what I am doing wrong?

thanks in advance!

I learned here that Postman and the firmware do not speak the same dialect of "http digest" somehow...

But the python script works like a charm:

I tried that, but I get a missing argument error on the api.loadauth subroutine, cus the "auth.data" is going in to self, and the filename is not specified, if I add that it doesn't work either, I am using python 3.7.5

not my field of expertise, i copied some lines from several places a while ago. 🤷‍♂️

Windows and Python 3.5.2 in my case. I changed the initAPI function to this:

 

# ...
	# dunno, if this has changed too?
    def loadAuth(self, filename):
        try:
            data = json.load(open(filename, "rt"))
            self.__setAuthData(data["id"], data["key"])
        except IOError:
            self.__checkAuth()
            self.saveAuth(filename)
        self.__checkAuth()

# ...

# always load data file from module directory
def initAPI(ip):
    # script name
    filename = os.path.realpath(__file__)
    sname = os.path.basename(filename)
    datafile = os.path.splitext(filename)[0] + ".data"

    # authenticate      
    api = Ultimaker3(ip, sname)
    api.loadAuth(datafile)
    
    return api

I'm not sure, either this (older) network printing doesn't work anymore or we use it in a wrong way?

I use only the new API for this, i hope it still works in the same way in this new "digital factory" age (my UM3 has not heard yet of those fancy things... 😏)

 

Have a look at the documentation on the printer.

http://169.254.168.50/cluster-api/v1/

 

Something like this (from a windows batch file):

 

set URL=http://169.254.168.50:80/cluster-api/v1/print_jobs/
set FILENAME=UM3_UltimakerRobot_support.gcode
curl -X POST --header "Content-Type: multipart/form-data" --header "Accept: application/json" -F "file=@%FILENAME%" %URL%

okey that works, but when I try to do the exact same thing in my python code I get a response 200 back, and the print doesn't start.

import UM3_API
UM3_API.start_print("UM3_UltimakerRobot_support.gcode")

.......

def start_print(file):
    api = initAPI("169.254.113.5")  
    if os.path.exists(file):
        jobname = os.path.basename(file)
        filepath = file
        print(filepath)
        print(api.post("cluster-api/v1/print_jobs", headers={"Content-Type": "multipart/form-data", "Accept": "application/json"}, files={"file": (jobname, open(filepath, "rb"))}))

what am I doing wrong?

dunno... but i would not use the "api" object at all for this task.

The cluster-api works different, no authentification, and does not know the "jobname" parameter (AFAIK).

 

Can't you simply mimic the curl command with a python library or such....?

I tried that already, but then I still get the 200 back instead of 201
