带有Daphne的Django Channel 2在开始时出现Heroku崩溃

Question

[我在heroku上使用Channels 2创建了一个django应用，但它从503错误代码开始崩溃。

2020-04-07T10:05:35.226253+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=www.mysite.com request_id=317bfbe6-9055-4957-9fbb-8190616c3964 fwd="" dyno= connect= service= status=503 bytes= protocol=https

Procfile：

release: python manage.py migrate
web : daphne myproject.asgi:application --port $PORT --bind 0.0.0.0 -v2 
worker: python manage.py runworker channels -v2

settings.py

ASGI_APPLICATION = 'myproject.routing.application'
# Channels
    CHANNEL_LAYERS = {
    "default": {
         'BACKEND': 'channels_redis.core.RedisChannelLayer',
        "CONFIG": {
            "hosts": [os.environ.get('REDIS_URL', 'redis://localhost:6379')],
        },

    },
}

asgi.py

import os
import django
from channels.routing import get_default_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
django.setup()
application = get_default_application()

您是否已在heroku中创建流程网络的实例？您可以在命令行中执行此操作：heroku ps:scale worker=1

在Procfile中将工作人员作为：

worker: python manage.py runworker channels --settings=<project-name>.settings -v2
