芹菜泡菜类型内容不允许出错

Question

即使我在settings.py中有以下行:

CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_TASKS_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
from kombu import serialization
serialization.registry._decoders.pop("application/x-python-serialize")

我仍然得到不允许追溯的泡菜内容.奇怪的是,我已经有芹菜在另一个地方完全相同的设置工作正常.如果有人可以提出解决方案,那将非常有帮助.Django版本是1.7.1,芹菜今天下载,所以应该是最新的.使用rabbitmq作为经纪人.以下是错误的完整回溯.

这是我在与settings.py文件并行的项目目录中的celery.py文件中所拥有的:

from __future__ import absolute_import
import os
from celery import Celery
from django.conf import settings
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'projectname.settings')
app = Celery('projectname',broker='amqp://',backend='amqp://',)
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))

如果需要其他信息,请告诉我

我相信你在找

CELERY_TASK_SERIALIZER

并不是

CELERY_TASKS_SERIALIZER

芹菜任务串
