Quick API Auth for Flask

A quick decorator function for api authorization on Flask endpoints

def require_appkey(view_function):
    @wraps(view_function)
    def decorated_function(*args, **kwargs):
        if request.headers.get('x-api-key') and request.headers.get('x-api-key') == key:
            return view_function(*args, **kwargs)
        else:
            abort(401)
    return decorated_function

Simply put this on your methods and it will require the API key for authorization.

@app.route('/create', methods=['POST'])
@require_appkey
def create():

  return 'Your function here'

Easy, and doesn’t require any more dependancies or packages.
