dt.strftime('%S')

[srdavicho]

I could runserver following hunterway55 comments: upgrading to django=1.10.5 and adding django-cors-headers==1.3.1, but the Postman register & login commands didn't work.

In apps/authentication/models.py

I replaced dt.strftime('%s') by dt.strftime('%S') and the Login & Register commands worked.

Token generation function is now:

def _generate_jwt_token(self):
    """
    Generates a JSON Web Token that stores this user's ID and has an expiry
    date set to 60 days into the future.
    """
    dt = datetime.now() + timedelta(days=60)

    token = jwt.encode({
        'id': self.pk,
        'exp': int(dt.strftime('%S'))
    }, settings.SECRET_KEY, algorithm='HS256')

    return token.decode('utf-8')

Hope it helps someone.

What version of Python are you using?

[srdavicho]

Python 3.5.1 on windows
Pip freeze:
appdirs==1.4.3
Django==1.10.5
django-cors-headers==1.3.1
django-cors-middleware==1.2.0
django-extensions==1.7.1
djangorestframework==3.4.4
packaging==16.8
PyJWT==1.4.2
pyparsing==2.2.0
six==1.10.0

I'm also currently doing the tutorial on Thinkster, and the upper change worked for the Login and Register Postman commands only, but did not work for Current User and Update User commands. I fixed the issue by making the following change:

#dt = datetime.now() + timedelta(days=60)

    token = jwt.encode({
        'id': self.pk,
        'exp': datetime.now()+ timedelta(days=60)
    }, settings.SECRET_KEY, algorithm='HS256')

    return token.decode('utf-8')

In my mind, you use Windows. I fix this problem like this
'exp': str(time.mktime(dt.timetuple()))[:-2]

[mkhan935]

same for me, I had to do %S for it work, maybe create a note in the actual code snippet

[dissdoc]

%S is not %s! It's wrong!

[mkhan935]

%S signifies seconds yes? what does %s mean?

[srdavicho]

Accorting to http://strftime.org/

%S means Second as a zero-padded decimal number. Example: 05

[rcdosado]

thanks for this, but still the fix is not yet committed in the repo. as of now.

[Nifled]

@dissdoc is right, %S is definitely not the same as %s. I've created a PR for a compatible solution for anyone still using this as a reference like I am.

Are there any updates to this? Followed this tutorial https://thinkster.io/tutorials/django-json-api/authentication and I'm getting error after error
