Python 包括Redis在内的Django将继续进行Heroku

在过去的几天里，我一直在尝试为我的网站设置此选项，但一直未能理解此特定错误

• 我在项目中使用了Django Cookiecutter锅炉夯实机
• 我使用Redis在本地添加芹菜来执行任务，这很有效
  太好了
• 我已将我的项目部署到Heroku

我现在尝试在我的生产环境中实现相同的任务，但是我现在使用的不是Redis，而是一个名为Redis的heroku插件。我是这样做的

在我的设置中：我从redis to go复制了这个。除了更改urlparse导入以满足Python 3标准外，未进行任何调整

production.py
import os

from urllib.parse

import urlparse

redis_url = urlparse(os.environ.get('REDISTOGO_URL', 'redis://localhost:6959'))

CACHES = { 'default': {

'BACKEND': 'redis_cache.RedisCache',

'LOCATION': '%s:%s' % (redis_url.hostname, redis_url.port),

'OPTIONS': {

'DB': 0,

'PASSWORD': redis_url.password, }

}

}

Procfile

我已经在Procfile中添加了以下行，并为我的工作人员添加了第二个dyno

worker: celery -A appname worker --beat

那个工人好像在工作。状态更改，然后关闭。它显然无法连接，请参见错误

我做错了什么

我的芹菜配置：

请包括您的芹菜配置。该错误消息表示芹菜正在尝试将AMQP用于代理，而不是redis。使用更多信息更新了我的问题。错误消息中的url是否与

REDISTOGO\u url

匹配？如果没有，是否可能您没有使用正确的设置？这听起来很合乎逻辑。查看我的代码，我发现在芹菜.Py中它指的是“config.settings.local”。。。指的是“芹菜经纪人URL=redis://localhost:6379". 链接此项修复了错误。[2020-05-18 03:12:51591:INFO/MainProcess]celery@325c7732-0025-412e-81a1-6C37DE6E7D准备就绪。看来我的芹菜工人准备好了，但没有收到任何任务。请包括你的芹菜配置。该错误消息表示芹菜正在尝试将AMQP用于代理，而不是redis。使用更多信息更新了我的问题。错误消息中的url是否与
