Request: Method to check if token is still valid

[ehennestad]

I tried to find something about this in the documentation and the source code (so I apologise if I missed something), but it would be useful to have a method for testing whether the token has expired, and also update the token if needed.

I tried to use the ping endpoint of the sea file api, but it seems like It does not require a valid token.

Other ideas or suggestions for best practices are also appreciated.

Update: I found the auth/ping which is what is needed, and suggest something like this:

try:
    auth_ping_endpoint_path = '/api2/auth/ping/' # self.id
    response = drive_client.get(auth_ping_endpoint_path)
    
except ebrains_drive.exceptions.ClientHttpError as e:
    if e.code == 403:
        raise ebrains_drive.exceptions.TokenExpired(e.code, 'The token has expired')
    else:
        raise ebrains_drive.exceptions.ClientHttpError(e.code, e.message)

edit: it seems you are referring to th token issued by seafile, and not by ebrains IAM. Please ignore the original post.

since the token is a standard JWT token, one could decode it with something like:

import json
from base64 import b64decode
import time

auth_token = "ey..."
tolerance=30 # if expires within 30seconds

_header, body, _sig, *_rest = auth_token.split('.')
exp = json.loads(b64decode(body.encode("utf-8") + b"====").decode("utf-8")).get("exp")

if exp - time.time() < tolerance:
    raise ebrains_drive.exceptions.TokenExpired(e.code, 'The token has expired')
