芹菜任务没有通过redis分配

Question

使用 Celery/redis 我尝试创建一个任务，但是在使用以下代码检查芹菜工作信息时 celery -A intranet_project worker -l info 我无法在那里添加任务。

Settings.py

BROKER_URL = 'redis://localhost:6379'
CELERY_RESULT_BACKEND = 'redis://localhost:6379'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TIMEZONE = TIME_ZONE

init.py

from __future__ import absolute_import

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app

__all__ = ('celery_app',)

celery.py

from __future__ import absolute_import
import os
from celery import Celery
from django.conf import settings

# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'intranet_project.settings')
app = Celery('intranet_project')

# Using a string here means the worker will not have to
# pickle the object when using Windows.
app.config_from_object('django.conf:settings')
app.autodiscover_tasks()


@app.task(bind=True)
def debug_task(self):
    print('Request: {0!r}'.format(self.request))

my_task.py

from celery.decorators import task
from celery import shared_task

@shared_task
def add(a,b):
    d = a + b
    return d

以下是服务器日志

[任务] . intranet_project.celery.debug_task

[2020-02-26 19:38:59,051: INFO/MainProcess] 连接到redis://localhost:6379// [2020-02-26 19:38:59,160: INFO/MainProcess] mingle: 寻找邻居 [2020-02-26 19:39:00,379: INFO/MainProcess] 打成一片: 一个人

Answer 1

我没有看到您执行任务的代码。

view.py（或任何您想触发任务的地方）

from .my_tasks import add

def action(request):
    add.delay(2,2)

然后您应该会在 celery 日志中看到如下一行：

[2020-02-26 14:11:40,765: INFO/MainProcess] 收到的任务: intranet_project.tasks.add[xxxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx]

芹菜任务没有通过redis分配
