我正在尝试让Flask与Ceite一起使用SQLite作为后端。但是,使用以下代码:
CELERY_BROKER_URL = 'sqla+sqlite:///' + os.path.join(basedir, 'celery.db')
def make_celery(app):
celery = Celery(app.import_name, broker=app.config['CELERY_BROKER_URL'])
celery.conf.update(app.config)
TaskBase = celery.Task
class ContextTask(TaskBase):
abstract = True
def __call__(self, *args, **kwargs):
with app.app_context():
return TaskBase.__call__(self, *args, **kwargs)
celery.Task = ContextTask
return celery
启动工人后I get this error when trying to call a dummy task:
error: [Errno 10061] No connection could be made because the target machine actively refused it
代码:
@app.route('/test')
def test():
t = add_together.delay(100,200)
return str(t.wait())
怎么了?我已经尝试使用Google搜索Sqllite / SQLAlchemy / Flask / Celery的任意组合,但一直无法找到解决方案。

正如您在跟踪中看到的,您的应用仍在尝试连接到rabbitmq-server。这意味着它没有正确配置。我没理解你使用CELERY_BROKER_URL
代替BROKER_URL
的原因。快速解决方案可能会改变这一点:
celery = Celery(app.import_name, broker=app.config['CELERY_BROKER_URL'])
到
celery = Celery(app.import_name,
broker='sqla+sqlite:///' + os.path.join(basedir, 'celery.db'),
backend='db+sqlite:///' + os.path.join(basedir, 'celery_results.db'))
让我们看看它是如何运作的

error: [Errno 10061] No connection could be made because the target machine actively refused it
错误通常表示目标端口不可用或被某种防火墙阻止。
File "C:\Users\Robus\banking_virtenv\lib\site-packages\amqp\transport.py", line 95, in __init__
raise socket.error(last_err)
error: [Errno 10061] No connection could be made because the target machine actively refused it
看起来它正在尝试使用AMQP传输进行连接。请检查您的配置。
