姜戈芹菜兔子问题："WARNING/MainProcess] Received and deleted unknown message. Wrong destination"

Question

My settings.py

CELERY_ACCEPT_CONTENT = ['json', 'msgpack', 'yaml', 'pickle', 'application/json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_RESULT_BACKEND = 'djcelery.backends.cache:CacheBackend'

celery.py 代码

from __future__ import absolute_import
import os
from celery import Celery
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'webapp.settings')
from django.conf import settings  
app = Celery('webapp')
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

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

tasks.py 代码

from __future__ import absolute_import
from celery.utils.log import get_task_logger
from celery import shared_task
import datetime
logger = get_task_logger(__name__)
@shared_task
def sample_code():
    logger.info("Run time:" + str(datetime.datetime.now().strftime("%Y-%m-%d %H:%M")))
    return None

在 shell 上，我正在导入并运行为"sample_code.delay（）"

请让我知道我错在哪里

Answer 1

对我来说解决

的方法是更改运行芹菜的命令

它给出了以下问题：

celery -A <app_path> worker --loglevel=DEBUG

但是如果我们使用：

celery -A <app_path> worker -l info

如果他们面临同样的问题，可能会对其他人有所帮助。
