python使用celery实现异步任务执行的例子

 ```broker_url = "redis://127.0.0.1/14"```

from celery import Celery
 # 为celery使用django配置文件进行设置

import os
if not os.getenv('DJANGO_SETTINGS_MODULE'):
  os.environ['DJANGO_SETTINGS_MODULE'] = 'model.settings.dev'

 # 创建celery应用

app = Celery('model')

 #导入celery配置

app.config_from_object('celery_tasks.config')
 #自动注册celery任务
app.autodiscover_tasks(['celery_tasks.sms'])

  import logging

  from celery_tasks.main import app
  from .yuntongxun.sms import CCP

  logger = logging.getLogger("django")

   #验证码短信模板
  SMS_CODE_TEMP_ID = 1

  @app.task(name='send_sms_code')
    def send_sms_code(mobile, code, expires):

  发送短信验证码
  :param mobile: 手机号
  :param code: 验证码
  :param expires: 有效期
  :return: None


  try:
    ccp = CCP()
    result = ccp.send_template_sms(mobile, [code, expires], SMS_CODE_TEMP_ID)
  except Exception as e:
    logger.error("发送验证码短信[异常][ mobile: %s, message: %s ]" % (mobile, e))
  else:
    if result == 0:
      logger.info("发送验证码短信[正常][ mobile: %s ]" % mobile)
    else:
      logger.warning("发送验证码短信[失败][ mobile: %s ]" % mobile)

from celery_tasks.sms import tasks as sms_tasks

class SMSCodeView(GenericAPIView):
  ...
    # 发送短信验证码 这是将时间转化为分钟，constants.SMS_CODE_REDIS_EXPIRES 是常量
    sms_code_expires = str(constants.SMS_CODE_REDIS_EXPIRES // 60)

    sms_tasks.send_sms_code.delay(mobile, sms_code, sms_code_expires)

    return Response({"message": "OK"})
