安排Heroku上的python脚本每30分钟发布一次，这不仅有用

2024-05-07 • 问答

我构建了一个简单的python机器人程序，该程序每30分钟发布一次推文。使用python time函数，一切在我的本地机器上都运行良好：

import time
sleep.time(1800)

我成功在30分钟后成功发送了该程序。但是部署到Heroku最初并没有成功（使用免费帐户），我离开了python time函数来调节机器人的时间间隔，但这没有用。问题不是它几乎要保持时间像28分钟，27分钟等，而是怪异地随机（例如5分钟间隔），然后是接下来的30分钟，然后是25分钟。

注意：由于Heroku的睡眠规定，我将本地计算机的设置时间从30分钟更改为29分钟。

我查找了这个问题并试图对其进行调整，并构建了一个clock.py程序来控制Heroku dyno。

from apscheduler.schedulers.blocking import BlockingScheduler
sched = BlockingScheduler()

#execute very 30 minutes
@sched.scheduled_job('interval',minutes=29)
def scheduled_job():
    #start logic
    sched.start()

机器人仍然会随机发帖，并且不会遵守规定的29分钟间隔。这是-Heroku日志--tail

的输出

我该如何确保它坚持正确的29分钟时间？

我尝试了Heroku调度程序，但只允许10分钟，1小时零1天

import time import datetime while True: current_time = datetime.datetime.now() if current_time.minute in [0,30]: # your function that tweets post_tweet() # sleep to avoid running the function again in the next loop time.sleep(120)

import time import datetime start_time = datetime.datetime.now() interval = start_time + datetime.timedelta(minutes=30) # dynamically create the interval times tweet_times = [start_time.minute,interval.minute] while True: current_time = datetime.datetime.now() if current_time.minute in tweet_times: # your function that tweets post_tweet() # sleep to avoid running the function again in the next loop time.sleep(120)
