将boto3.client实例传递给celery任务会引发JSON序列化错误

import boto3
from celery import Celery

app = Celery('tasks', broker='redis://localhost:6379/0')

def extract_serializable_data(client):
    # 从boto3.client实例中提取可序列化的数据
    serialized_data = {
        'access_key': client._request_signer._credentials.access_key,
        'secret_key': client._request_signer._credentials.secret_key,
        'region_name': client._client_config.region_name
    }
    return serialized_data

@app.task
def process_task(serialized_data):
    # 根据提取的数据重新创建boto3.client实例
    client = boto3.client(
        's3',
        aws_access_key_id=serialized_data['access_key'],
        aws_secret_access_key=serialized_data['secret_key'],
        region_name=serialized_data['region_name']
    )
    # 在这里执行需要使用boto3.client实例的任务逻辑
    # ...

# 创建boto3.client实例
s3_client = boto3.client('s3')

# 提取可序列化的数据
serialized_data = extract_serializable_data(s3_client)

# 将数据传递给celery任务
process_task.delay(serialized_data)
