EDIT:查看获取队列中任务列表的其他答案。

你应该看这里: 芹菜指南-检查工人

基本上是这样的:

my_app = Celery(...)

# Inspect all nodes.
i = my_app.control.inspect()

# Show the items that have an ETA or are scheduled for later processing
i.scheduled()

# Show tasks that are currently active.
i.active()

# Show tasks that have been claimed by workers
i.reserved()

这取决于你想要什么

这在我的申请中很奏效:

def get_celery_queue_active_jobs(queue_name):
    connection = <CELERY_APP_INSTANCE>.connection()

    try:
        channel = connection.channel()
        name, jobs, consumers = channel.queue_declare(queue=queue_name, passive=True)
        active_jobs = []

        def dump_message(message):
            active_jobs.append(message.properties['application_headers']['task'])

        channel.basic_consume(queue=queue_name, callback=dump_message)

        for job in range(jobs):
            connection.drain_events()

        return active_jobs
    finally:
        connection.close()

Active_jobs将是一个字符串列表，对应于队列中的任务。

不要忘记将CELERY_APP_INSTANCE替换为您自己的。

感谢@ashish在这里为我指出了正确的方向:https://stackoverflow.com/a/19465670/9843399

要获得队列上的任务数，你可以使用flower库，下面是一个简化的例子:

from flower.utils.broker import Broker
from django.conf import settings

def get_queue_length(queue):
    broker = Broker(settings.CELERY_BROKER_URL)
    queues_result = broker.queues([queue])
    return queues_result.result()[0]['messages']

Redis json序列化的复制粘贴解决方案:

def get_celery_queue_items(queue_name):
    import base64
    import json  

    # Get a configured instance of a celery app:
    from yourproject.celery import app as celery_app

    with celery_app.pool.acquire(block=True) as conn:
        tasks = conn.default_channel.client.lrange(queue_name, 0, -1)
        decoded_tasks = []

    for task in tasks:
        j = json.loads(task)
        body = json.loads(base64.b64decode(j['body']))
        decoded_tasks.append(body)

    return decoded_tasks

它与Django一起工作。只是别忘了改变你的项目。

要从后端检索任务，使用这个

from amqplib import client_0_8 as amqp
conn = amqp.Connection(host="localhost:5672 ", userid="guest",
                       password="guest", virtual_host="/", insist=False)
chan = conn.channel()
name, jobs, consumers = chan.queue_declare(queue="queue_name", passive=True)

from celery.task.control import inspect
def key_in_list(k, l):
    return bool([True for i in l if k in i.values()])

def check_task(task_id):
    task_value_dict = inspect().active().values()
    for task_list in task_value_dict:
        if self.key_in_list(task_id, task_list):
             return True
    return False
