我使用了这个框架的 django-apscheduler
代码内容
# -*- coding: utf-8 -*- import datetime import time from apscheduler.schedulers.background import BackgroundScheduler from django_apscheduler.jobstores import DjangoJobStore, register_events, register_job from apscheduler.executors.pool import ThreadPoolExecutor, ProcessPoolExecutor executors = { 'default': ThreadPoolExecutor(10), 'processpool': ProcessPoolExecutor(3) } scheduler = BackgroundScheduler(executors=executors) scheduler.add_jobstore(DjangoJobStore(), 'default') def cron_test(): print '当前时间：{0}'.format(datetime.datetime.now()) def cron_task(run_time): task_idss = str(time.time()) print task_idss scheduler.add_job(func=cron_test, next_run_time=run_time, id=task_idss) scheduler.start() 在 django 的一个 view 里面调用
class GameOpenTimeView(View): def post(self, request, obj_id): print obj_id open_time = request.POST.get("open_time") print open_time open_time = datetime.datetime.strptime(open_time,"%Y-%m-%d %H:%M:00") print type(open_time) print open_time cron_task(open_time) return JsonResponse({'status': 'success'}) 时间由前端页面传入
问题
当我第一次传一个时间进入，可以正常生成一个任务点
当我第二次传入一个时间，出现告警说
return self.dispatch(request, *args, **kwargs) File "/Users/apple/OneDrive/Code_7zGame/Envs/tdops/lib/python2.7/site-packages/django/views/generic/base.py", line 88, in dispatch return handler(request, *args, **kwargs) File "/Users/apple/OneDrive/vultr_svn/Django_myself/tdops/pro1/views.py", line 340, in post cron_task(open_time) File "/Users/apple/OneDrive/vultr_svn/Django_myself/tdops/opsbase/schedwork.py", line 23, in cron_task scheduler.start() File "/Users/apple/OneDrive/Code_7zGame/Envs/tdops/lib/python2.7/site-packages/apscheduler/schedulers/background.py", line 33, in start BaseScheduler.start(self, *args, **kwargs) File "/Users/apple/OneDrive/Code_7zGame/Envs/tdops/lib/python2.7/site-packages/apscheduler/schedulers/base.py", line 134, in start raise SchedulerAlreadyRunningError SchedulerAlreadyRunningError: Scheduler is already running [04/Sep/2018 20:53:21] "POST /pro1/gameopentime/1003/ HTTP/1.1" 500 18550 这个是为何，这个模块之前也是有用过，也没出现这样当情况，不过之前是直接使用了 apscheduler 模块 然后后面也有换成了 apscheduler 模块试过，也是一样情况的
正常不是一个任务就一个 scheduler.start() 的么,为何不给再起一个的。
