flask_jwt_extended.exceptions.NoAuthorizationError: Missing Authorization Header

[wisp888]

from flask import Flask
from flask_jwt_extended import JWTManager, jwt_required
from flask_restful import Api, Resource

app = Flask(__name__)
app.config['PROPAGATE_EXCEPTIONS'] = True

api = Api(app)
jwt = JWTManager(app)


class SomeRoute(Resource):
    @jwt_required
    def post(self):
        return {'message':'success'}, 200


api.add_resource(SomeRoute, '/some_route', endpoint='some_route')

if __name__ == '__main__':
    app.run(debug=False)

post the url without token or token expired
use flask_restful no problem!

but use flask_restplus it will raise exception

from flask import Flask
from flask_jwt_extended import JWTManager, jwt_required
from flask_restplus import Api, Resource

app = Flask(__name__)
app.config['PROPAGATE_EXCEPTIONS'] = True

api = Api(app)
jwt = JWTManager(app)


class SomeRoute(Resource):
    @jwt_required
    def post(self):
        return {'message':'success'}, 200


api.add_resource(SomeRoute, '/some_route', endpoint='some_route')

if __name__ == '__main__':
    app.run(debug=False)

it will return

.......
    raise NoAuthorizationError(errors[0])

Flask-Restplus has a bug where native flask error handlers don’t work. Hopefully they will fix that eventually, but you should be able to use this as a work around in the mean time: #86 (comment)

jwt._set_error_handler_callbacks(api)`

@vimalloc @wisp888 I tried using the turnaround hack mentioned above. But I keep getting the No Authorization Error error.
Also, the IDE - PyCharm keeps on suggesting to me that through this line jwt._set_error_handler_callbacks(api), I am trying to access a protected member. Can you please suggest me a way out?

@aniketsnv-1997 jwt._set_error_handler_callbacks(api) is a work around for flask-restplus. It looks like you are using flask-restful, so that shouldn't apply here. Take a look #86 for some more details

[aniketsnv-1997]

@vimalloc I did try to use flask_restplus instead of flask_restful. However, whenever I go to the default route of my application, which is http://127.0.0.1:5000/, I get the result displayed in the screenshot below

Whereas, when I use flask-restful, my default route works fine as expected -

[aniketsnv-1997]

Also, when I visit the api http://127.0.0.1:5000/add-a-new-user while using flask_restplus, I get the error as TypeError: ShowUsersForm() takes no arguments. However, I am not passing any parameter to the api. The same route works fine while using flask_restful

The resource code is
`
class ShowUsersForm(Resource):
def get(self):
# current_user = UsersModel.find_by_email_address(get_jwt_identity()).name

    headers = {'Content-Type': 'text/html'}
    return make_response(render_template("./users/forms/add_user.html",
                                         title="Add User",
                                         current_user="current_user",
                                         roles=RolesModel.get_all_roles(),
                                         projects=ProjectsModel.get_all_projects(),
                                         rights=RightsModel.get_all_rights()
                                         )
                         , 200, headers)

`

As a result, I am deadlocked between flask_restful and flask_restplus. ANy help upon this will be much appreciated!
