如何在Django中触发30秒后的事件？

CELERY_BROKER_URL = 'redis://localhost:6379/0'
CELERY_RESULT_BACKEND = 'redis://localhost:6379/0'

from celery import Celery
from datetime import timedelta

app = Celery('your_project_name', broker='redis://localhost:6379/0')

@app.task
def delayed_task():
    # 在这里编写你想要触发的事件逻辑
    pass

from your_project_name.tasks import delayed_task

def your_view(request):
    delayed_task.delay()
    return HttpResponse('任务已触发')

celery -A your_project_name worker --loglevel=info

from celery.schedules import crontab

app.conf.beat_schedule = {
    'run-every-30-seconds': {
        'task': 'your_project_name.tasks.delayed_task',
        'schedule': timedelta(seconds=30),
    },
}
