input: Write a function that generates a basic REST API using Flask with JWT authentication and provides endpoints for managing items. The function should return the Flask app object.
  from flask import Flask, request
  from flask_restful import Resource, Api
  from flask_jwt import JWT, jwt_required
  
  def generate_rest_api():
   app = Flask(name)
   api = Api(app)
  
   # Setup JWT authentication
   app.secret_key = 'super-secret-key'
   jwt = JWT(app, authenticate, identity)
  
   items = []
  
   class Item(Resource):
   @jwt_required()
   def get(self, name):
   for item in items:
   if item['name'] == name:
   return item
   return {'item': None}, 404
  
   def post(self, name):
   new_item = {'name': name, 'price': 12.00}
   items.append(new_item)
   return new_item, 201
  
  
   class ItemList(Resource):
   def get(self):
   return {'items': items}
  
  
   api.add_resource(Item, '/item/<string:name>')
   api.add_resource(ItemList, '/items')
  
   return app
  
  # Example usage
  assert generate_rest_api() is not None
output:
