芹菜即使允许腌制也不接受腌制

问题描述

我正在尝试编写一个芹菜应用程序，它将Numpy数组(或任何任意对象)传递给Worker。据我所知，这需要通过pickle进行序列化(注意：我知道安全问题，但在本例中这不是问题)。

但是，即使在尝试了所有我能找到的允许Pickle作为序列化程序的方法之后，我仍然得到以下Kombu异常：

kombu.exceptions.ContentDisallowed: Refusing to deserialize untrusted
content of type pickle (application/x-python-serialize)

我的当前文件当前为：

# tasks.py
from celery import Celery
app = Celery(
    'tasks',
    broker='redis://localhost',
    accept_content=['pickle'],
    task_serializer='pickle'
)

@app.task
def adding(x, y):
    return x + y

if __name__ == '__main__':
    import numpy as np
    adding.apply_async((np.array([1]), np.array([1])), serializer='pickle')

此外，我还有一个配置文件：

# celeryconfig.py
print('configuring...')

accept_content = ['pickle', 'application/x-python-serialize']
task_serializer = 'pickle'
result_serializer = 'pickle'
from kombu import serialization
serialization.register_pickle()
serialization.enable_insecure_serializers()

推荐答案

对于回答此问题的任何人：

答案是使用app.config_from_object方法：

import celeryconfig
app.config_from_object(celeryconfig)
