python - Celery pickle type content disallowed 错误

Question

即使我在 settings.py 中有以下几行:

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")

我仍然收到 pickle content disallowed traceback。奇怪的是，我已经让 celery 在另一个地方使用完全相同的设置正常工作。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，celery 是今天下载的，所以应该是最新的。使用 rabbitmq 作为代理。以下是错误的完整回溯。

这是我在项目目录中与 settings.py 文件并行的 celery.py 文件中的内容:

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))

如果需要更多信息，请告诉我

我相信你正在寻找

CELERY_TASK_SERIALIZER

不是

CELERY_TASKS_SERIALIZER

celery-task-serializer
