Question

我正在开发一个Django项目，该项目已推向Heroku，用于后台任务，我使用了Celery。尽管Celery在本地工作正常，但是在Heroku服务器上，我观察到celery worker崩溃了。我已经在CLOUDAMQP_URL中正确设置了settings.py，并在Procfile中配置了工作程序配置，但是工作程序仍然崩溃了。

Procfile

web: gunicorn my_django_app.wsgi --log-file -
worker: python manage.py celery worker --loglevel=info

Settings.py

...
# Celery
BROKER_URL = os.environ.get("CLOUDAMQP_URL", "django://")
#CELERY_BROKER_URL = 'amqp://localhost'
BROKER_POOL_LIMIT = 1
BROKER_CONNECTION_MAX_RETRIES = 100
CELERY_TASK_SERIALIZER="json"
CELERY_RESULT_SERIALIZER="json"
CELERY_RESULT_BACKEND = "amqp://"
