Apscheduler add_job trigger
Apscheduler add_job trigger- scheduleradd_job() 第二个参数是trigger,它管理着作业的调度方式。它可以为date, interval或者cron。对于不同的trigger,对应的参数也相同。 trigger 1) interval 间隔调度 循环执行,间隔固定的时间 # Schedule job_function to be called every two hours schedadd_job(job_function, 'interval', hours=2) apschedulertriggerscron API Trigger alias for add_job() cron class apschedulertriggerscronCronTrigger(year=None, month=None, day=None, week =None 需求是在某一指定的时刻执行操作 网上的建议多为通过调用Scheduler的add_date_job实现 不过APScheduler 301与之前差异较大, 无法通过上述方法

Advanced Python Scheduler (APScheduler) is a Python library that lets you schedule your Python code to be executed later, either just once or periodically You can add new jobs or remove old ones on the fly as you please If you store your jobs in a database, they will also survive scheduler restarts and maintain their stateDeftick(parameter)print(parameter)scheduleradd_job(function,args=(1,),trigger='interval',seconds=3) #Trigger A trigger instructs the scheduler when is the next time a job should run All jobs have their own triggers As shown earlier, "interval" is one of the triggers """This job deletes all apscheduler job executions older than `max_age` from the database"""
Register any APScheduler jobs as you would normally Note that if you haven't set DjangoJobStore as the 'default' job store, then you will need to include jobstore='djangojobstore' in your scheduleradd_job() calls Advanced Usage djangoapscheduler assumes that you are already familiar with APScheduler and its proper use In this case, we add 10 jobs that will run scheduled_task via appapscheduleradd_job and the following keyword arguments func=scheduled_task the function to run afterwards is scheduled_task trigger='date' an indication that we want to run the task immediately afterwards, since we did not supply an input for run_date After that, we add 10 jobs that will run scheduled_task via appapscheduleradd_job and the following keyword arguments func=scheduled_task the function to run afterwards is scheduled_task trigger='date' an indication that we want to run the task immediately afterwards, since we did not supply an input for run_date
