celery学习记录

启动redis服务

# 保存为start_redis.batredis-server.exe redis.windows.conf

不废话直接上代码

#tasks.pyfrom celery import CeleryBROKERS = 'redis://localhost:6379/0'BACKEND = 'redis://localhost:6379/1'app = Celery('tasks', broker=BROKERS, backend=BACKEND)@app.taskdef add(x, y):    return x + y

#将此行命令保存为.bat文件，方便后面调试celery -A tasks.py worker --loglevel=info

#启动ipython>>> from tasks import add>>> r = add.delay(10, 20)>>> r.result # 若没有backend参数，调用result时会报错,可以将backend参数去掉，重启worker#30>>> r.ready()#True>>> r.status#'SUCCESS'

学习过程成碰到了一个报错：

version = 4.0.0、4.1.0

...tasks, accept, hostname = _locValueError: not enough values to unpack (expected 3, got 0)

解决办法：安装3.1.24、3.1.25版本

pip install celery==3.1.25
