python - 请教一下大家，在django或者其他的项目中做定时任务？

Question

有时候，需要在项目中做一些定时的任务，例如:我需要每隔几分钟去访问一个接口，然后根据返回值，做后续操作。

请教下，如何来实现？（PS：如果是用系统的crontab就不要说了。）

目前google了一种方法是使用celery。请加下大家，是否是条长期可行之路。

Answer 1

If you use Django’s own server to run your website, you can use django-celery. But if it is a website running with uWSGI, it is best to use uWSGI's signal for scheduled tasks. Other scheduled tasks are likely to be killed by uWSGI because they occupy the thread for a long time. I have worked on a website before that needs to crawl data on a scheduled basis. After trying several solutions, I finally used uWSGI's signal, which is more stable.

Answer 2

django-celery can meet your requirements

Answer 3

You can also use independent Celery, just use Celery's beat for scheduled tasks.

Answer 4

You can use crontab directly. If you want to better manage the scheduled process (such as using the supervisord tool), you can use celery scheduled tasks.
Here is a question: Flask configures celery scheduled tasks

Answer 5

Someone made a Django module: django_crontab

Answer 6

For scheduled tasks, I usually use huey. I have used crontab before, but the virtual environment on the server cannot be activated using the script. I have been working on it for a long time without solving it. Then I found huey, which is actually similar to the django project. An app is installed that can implement multi-threading, periodicity and other functions.

Answer 7

Why not use crontab? crontab is the most stable.

Answer 8

You can use Scheduler, because the content is a bit more, if you need examples, you can contact me.
