Python/Django 项目上的 Heroku/Redis 连接错误

Question

我正在尝试设置 Django，以便在我到达模型中的特定日期时发送自动电子邮件。但是我设置了一个 Heroku-Redis 服务器并试图连接到它。我创建了一个简单的任务来测试芹菜是否正常工作，但它总是 returns 出现以下错误：

Error while reading from socket: (10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None)

我按照网站设置celery：

celery.py:

import os

from celery import Celery

# Set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'incFleet.settings')

app = Celery('incFleet')

# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django apps.
app.autodiscover_tasks()


@app.task(bind=True)
def debug_task(self):
    print(f'Request: {self.request!r}')

Tasks.py

import datetime    
from celery import shared_task, task
from time import sleep
from .models import trucks
from datetime import datetime


@shared_task()
def sleepy(duration):
    sleep(duration)
    return 0

#@shared_task()
#def send_warning():

我的看法：

def index(request):
    sleepy.delay(5)
    return render(request, 'Inventory/index.html')

还有我的settings.py

# Celery Broker - Redis
CELERY_BROKER_URL = 'redis://:p0445df1196b44ba70a9bd0c84545315fec8a5dcbd77c8e8c4bd22ff4cd0a2ff4@ec2-54-167-58-171.compute-1.amazonaws.com:11900/'
    CELERY_RESULT_BACKEND = 'redis://:p0445df1196b44ba70a9bd0c84545315fec8a5dcbd77c8e8c4bd22ff4cd0a2ff4@ec2-54-167-58-171.compute-1.amazonaws.com:11900/'
    CELERY_ACCEPT_CONTENT = ['json']
    CELERY_TASK_SERIALIZER = 'json'

Answer 1

过了一会儿，我意识到问题出在我办公室的网络上。我试图访问的端口已关闭。一旦我在实际服务器上激活了 redis，它就开始正常工作了。

Answer 2

heroku config | grep REDIS

使用此代码
