18，flask项目中使用celery

导包：
from celery import Celery
from celery.result import AsyncResult

app.config['CELERY_BROKER_URL'] = 'redis://localhost:6379/0'
app.config['CELERY_RESULT_BACKEND'] = 'redis://localhost:6379/0'
celery = Celery(app.name, broker=app.config['CELERY_BROKER_URL'])
celery.conf.update(app.config)

　　

项目中调用：

res = get_data.delay(fp_info)   get_data为耗时的程序
id =res.id
async_task = AsyncResult(id=id, app=celery)
result = async_task.get()    # 返回的结果

@celery.task
def get_data(fp):  在函数上加上修饰器
   # 逻辑代码
　　pass

　　

　

启动redis: redis-cli
celery: celery -A app:celery worker --loglevel=info   #app为你的flask  app
启动flask: python app.py
