python-错误R10（启动超时）->Web进程未能在启动后60秒内绑定到$PORT

Question

我正在heroku部署一个python脚本，该脚本将在每个3 minutes之后向另一个服务器发出请求。

部署进行得很好，但是当我看到logs时，我得到了这些errors。

Procfile

web: python script.py --log-file -

script.py

import sys
import requests
from apscheduler.schedulers.blocking import BlockingScheduler

sched = BlockingScheduler()

@sched.scheduled_job('interval', minutes=3)
def timed_job():
    try:
        request = requests.get(url='https://royal-tag-services.herokuapp.com/api/sms-service/scheduler/')
    except Exception as e:
        print >>sys.stderr, 'scheduler request failed'

sched.start()

Result of 'tree -L 1' command

Answer 1

在Procfile中将“web”替换为“worker”。
