Python 用django ，celery 實現郵件發送

1.創建一個django項目（如email_celery）

2.創建一個app（如app_celery）

3.在項目文件settings.py中INSTALLED_APPS裏面註冊app，並且添加需要用到的celery和send_email相關的語句

# celery settings
CELERY_BROKER_URL = 'amqp://root:******@192.**.**.**'（數據庫用戶名，密碼，主機或虛擬機ip）
CELERY_RESULT_BACKEND ='redis://192.**.**.**:6379/6'(ip上下一致，6379爲redis端口)

# email
EMAIL_BACKEND ='django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.163.com'(可選)
EMAIL_HOST_PASSWORD = '*******'
DEFAULT_FROM_USER = EMAIL_HOST_USER = '*********@163.com'
EMAIL_PORT = 25
EMAIL_USE_TLS = True

4.在app中創建一個py文件tasks.py

from __future__ import absolute_import
from celery import shared_task

from django.core.mail import send_mail
import logging

loger = logging.getLogger(__name__)

@shared_task
def celery_send_email(subject,message,from_email,recipient_list,**kwargs):
    try:
        print('我要發郵件了')
        send_mail(subject,message,from_email,recipient_list,**kwargs)
        print('發送郵件成功')
        return 'email_send_success!'
    except Exception as e:
        print('email_send_error',e)

5.在項目文件email_celery中創建一個py文件celery.py

from __future__ import absolute_import

import os
from celery import Celery

# 爲celery 程序設置DJANGO_SETTINGS_MODULE環境變量
os.environ.setdefault('DJANGO_SETTINGS_MODULE','email_celery.settings')

app = Celery('email_celery')

# 從django的設置文件中導入celery的設置

app.config_from_object('django.conf:settings',namespace='CELERY')

# 從所有已經註冊的app中加載任務模塊（tasks）
app.autodiscover_tasks()

6.然後在app中的views.py中

from django.shortcuts import render
from django.http import HttpResponse

from app_celery.tasks import celery_send_email
# Create your views here.

def add_task_send_email(request):
    celery_send_email.delay('郵件的主題','這是一個簡單的測試郵件','**********@163.com',
                      ['*******@qq.com'])
    return HttpResponse('send email success')

這樣以後執行此django文件就可以實現簡單的diango-celery的郵件發送。
