安装
pip install celery-streaming-result
使用方法
服务端
import time
import redis
from celery.app import app_or_default
from celery_streaming_result import CeleryStreamingResultManager
app = app_or_default()
redis_instance = redis.Redis()
csrm = CeleryStreamingResultManager(redis_instance)
@app.task(bind=True)
def task1(celery_task):
result = []
for i in range(10):
csrm.append_result_chunk(celery_task, i)
result.append(i)
csrm.append_ended_chunk(celery_task)
return result
客户端(同步)
import redis
from celery.app import app_or_default
from celery_streaming_result import CeleryStreamingResultManager
# 根据你的task定义,正确引用
from test_server import task1
app = app_or_default()
redis_instance = redis.Redis()
csrm = CeleryStreamingResultManager(redis_instance)
# 生成一个异步任务
atask1 = task1.delay()
# 读取该异步任务的结果分片
for chunk in csrm.get_result_chunks(atask1):
print(chunk, end="-", flush=True)
客户端(异步)
from redis import asyncio as aioredis
from celery.app import app_or_default
from celery_streaming_result import CeleryStreamingResultManager
from celery_streaming_result import start_celery_task_async
from celery_streaming_result import get_celery_task_result_async
from test_server import task1 # 根据你的task定义,正确引用
app = app_or_default()
redis_instance = aioredis.Redis()
csrm = CeleryStreamingResultManager(redis_instance)
async def on_finished(celery_task, break_flag=False):
print("on finished...")
task_result = await get_celery_task_result_async(
celery_task,
)
# 这里的task_result值是celery任务的返回值。
# 一般来说是所有结果分片的集合,但实际只取决于celery任务的实现。
atask1 = await start_celery_task_async(
task1
) # task1.delay()是一个同步函数。需要使用`sync_to_async`进行转化。
# 读取该异步任务的结果分片,如果任务结果,则回调on_finished函数。
async for chunk in csrm.get_result_chunks(
atask1,
on_finished=on_finished,
):
print(chunk, end="-", flush=True)
