我有一个简单的Flask Restful API,由于某些端点需要大量的执行时间,因此我想将请求作为Celery任务执行。
main.py:
from flask import Flask
from flask_restful import Api
from flask_celery import make_celery
app = Flask(__name__)
app.config['CELERY_BROKER_URL'] = 'redis://localhost:6379/0',
app.config['CELERY_RESULT_BACKEND'] = 'redis://localhost:6379/0'
celery = make_celery(app)
api = Api(app)
api.add_resource(someResource, '/someendpoint/')
if __name__ == '__main__':
app.run(debug=True)
与make_celery.py:
from celery import Celery
def make_celery(app):
celery = Celery(
app.import_name,
backend=app.config['CELERY_RESULT_BACKEND'],
broker=app.config['CELERY_BROKER_URL']
)
celery.conf.update(app.config)
class ContextTask(celery.Task):
def __call__(self, *args, **kwargs):
with app.app_context():
return self.run(*args, **kwargs)
celery.Task = ContextTask
return celery
我现在想定义我在resource.py中定义的资源是一个芹菜任务:
class Cost(Resource):
def get(self):
result = some_code
return result
在这里使get方法成为芹菜任务的最方便的方法是什么?
非常感谢!
