Celery example implementation of sending messages on a timed basis

1. Configuration files

VI setting.py

#coding: Utf-8import osfrom datetime Import timedeltabroker_url = ' REDIS://127.0.0.1:6379/13 ' celery_result_backend = ' REDIS://127.0.0.1:6379/14 ' Celery_timezone = ' Asia/shanghai ' CELERY_ENABLE_UTC = Truecelery_task_serializer = ' JSON ' # Task serialization and deserialization using the Msgpack scheme #celery_result_serializer = ' JSON ' # Read task Results General performance requirements are not high, so use a more readable json#celery_task_result_ EXPIRES = 60 * 60 * 24 # Task Expiration time, not recommended to write directly 86400, should let such magic number expression more obvious celery_accept_content = [' JSON '] # Specifies the accepted content type celerybeat_sched ULE = {' Send_mail ': {' task ': ' Celery_test.tasks.send_mail ', ' Schedule ': Timedelta (seconds=10),}}

2. Function module

VI tasks.py

#coding: Utf-8from server import appimport random,string,smtplib@app.taskdef send_mail ():         subject= "Temporary login password"          host= "Smtp.163.com"         # TO=mail         to= ' [email protected] '         from= "[email protected]"         text=str (Random.randint (1000,9999))         body=string.join (          "from:%s"%from,         "to:%s"%to,          "subject:%s"%subject,         "", text), "\ r \ n")          server=smtplib. SMTP (HOST)         server.login ("[EmAil protected] "," third party Send Verification Code ")         server.sendmail (FROM,[TO],BODY )         server.quit ()          Return true

3. Starting module

VI server.py

From celery import celeryapp=celery (' Celery_test ', include=[' celery_test.tasks ']) app.config_from_object (' Celery_ Test.setting ') if __name__== ' __main__ ': App.start ()

4. Start the worker and perform the task

Celery-a Celery_test.server worker-l Info

5. Start beat, generate tasks

Celery-a Celery_test.server Beat

6. Directory Structure

celery_test/{server.py,setting.py,tasks.py}
