I am trying to create a back end using Flask-JWT for a website, so I am at the authentication part.
I have started with that link :
https://pythonhosted.org/Flask-JWT/
with the code provided as example.
But I am trying to link that with a database that contains credential, so here is the code "cleaner" by using my database function :
(to understand, main function of Identification.login check if user/password is in database, and return information on the login (wrong user, wrong password, success) + Id of the user from database)
from flask import Flask
from flask_jwt import JWT, jwt_required, current_identity
from Identification.login import main #Function that test password within database
class User(object):
def __init__(self, id, username, password):
self.id = id
self.username = username
self.password = password
def authenticate(username, password):
result = main(username, password)
if result['value'] == 0:
return User(result['id'], username, password)
def identity(payload):
# TODO
# user_id = payload['identity']
# return userid_table.get(user_id, None)
app = Flask(__name__)
app.debug = True
app.config['SECRET_KEY'] = 'super-secret'
jwt = JWT(app, authenticate, identity)
@app.route('/protected')
@jwt_required()
def protected():
return '%s' % current_identity
if __name__ == '__main__':
app.run()
my question is about the identity function : I don't understand how I need to manage it. From the example of the site, the parameter is simple "payload" but don't get what it is exactly. The only description I have is : https://pythonhosted.org/Flask-JWT/_modules/flask_jwt.html#JWT
So my question is how I need to user identity function? and in my example, how I should adapt it?
Also, if you have a clear documentation on flask-jwt that allow to understand clearly this module, it would be a great help
Thanks
