I reached at this point in my app, but when i tried executing login and logout in localhost login worked fine but logout gave this error : provide a valid authorization token .

Please take a look. Thanks in advance

Hey, I've just solve the logout problem. You should specify an authorization dictionary and give it to Api as a parameter. For that:

Firstly add this ->

authorizations = { 'Basic Auth': { 'type': 'apiKey', 'in': 'header', 'name': 'Authorization' }, }

to the root directory init.py and then add authorizations dictionary as an Api param ->

api = Api(blueprint, doc='/documentation', title='title here', version='1.0', description='a description', security='Basic Auth', authorizations=authorizations )

This makes all api methods required auth. Last thing you should do is replaceing auth_token = data.split(" ")[1] with this: auth_token = data.split(" ")[0] in logout_user function in auth_helper.py, in first if block.

This worked for me, hope this helps you too.

where to add the api line ?
when i added it to the same init file ....it said name Api is not defined.

[prashantjeena]

this is my init.py file

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_bcrypt import Bcrypt

from .config import config_by_name

db = SQLAlchemy()
flask_bcrypt = Bcrypt()

authorizations = { 'Basic Auth': { 'type': 'apiKey', 'in': 'header', 'name': 'Authorization' }, }
api = Api(blueprint, doc='/documentation', title='title here', version='1.0', description='a description', security='Basic Auth', authorizations=authorizations )
def create_app(config_name):
    app = Flask(__name__)
    app.config.from_object(config_by_name[config_name])
    db.init_app(app)
    flask_bcrypt.init_app(app)
    return app

No, not into this init.py file, you should put authorizations into other init.py (located in upper package)

There is two file named init.py. One is belong to main package and other one is belong to top package. My name of top package of main is app. So i put that into app's init.py.

You should do the same. Not into inner init.py

You need an init.py file like this:

# app/__init__.py

from flask_restplus import Api
from flask import Blueprint

from .main.controller.user_controller import api as user_ns
from .main.controller.auth_controller import api as auth_ns


blueprint = Blueprint('api', __name__, url_prefix='/api')


authorizations = {
    'Basic Auth': {
        'type': 'apiKey',
        'in': 'header',
        'name': 'Authorization'
    },
}


api = Api(blueprint,
          doc='/documentation',
          title='title here',
          version='1.0',
          description='description here',
          security='Basic Auth',
          authorizations=authorizations
          )

api.add_namespace(user_ns, path='/user')
api.add_namespace(auth_ns)

@prashantjeena !! but you have to set the token in your Header request, see the screenshot

Getting this error on auth_helper logout_user method
auth_token = data.split("")[0]
AttributeError: 'dict' object has no attribute 'split'

@Kpatric! Check your data param def logout_user(data): if it's a dict type.

EDIT :
I just saw that a blank space is missed in auth_token = data.split("")[0] it have to be auth_token = data.split(" ")[0]
