django、celery异步发邮件
- django自带的send_mail发邮件功能执行发邮件功能会因为网络的原因造成花费的时间过长,为了解决这个问题,可以用celery + redis代替
- 安装包:
- pip install celery
- pip install redis
- 在django的根目录下新建celery_tasks文件夹,在该文件夹下新建tasks.py:
from celery import Celery
from django.conf import settings
from django.core.mail import send_mail app = Celery('celery_tasks.tasks', broker='redis://127.0.0.1:6379/8') @app.task
def send_register_active_email(email, username, token):
subject = '测试'
message = ""
from_email = settings.EMAIL_FROM
recipient_list = [email]
html_message = '<h1>欢迎{}来到测试</h1>请点击下面链接激活<br><a href="http://http://127.0.0.1:8000/user/active?token={}">点击此处激活</a>'.format(
username, token)
send_mail(subject, message, from_email, recipient_list, html_message=html_message)- 调用该方法:
class Register(View):
def get(self, request):
return render(request, 'user/register.html') def post(self, request):
username = request.POST.get('username', '')
password = request.POST.get('password', '')
email = request.POST.get('email', '') # 校验用户名是否重复
try:
user = User.objects.get(username=username)
except User.DoesNotExist:
user = None if user:
data = {'errmsg': '用户名已存在'}
return JsonResponse(data)
# try:
# user = User.objects.ger(email=email)
# except User.DoesNotExist:
# user = None
# if user:
# data = {'errmsg': '邮箱已被注册'}
# return JsonResponse(data)
user = User.objects.create_user(username=username, password=password, email=email)
user.is_active = 0
user.save() info = {'user_id': user.id}
serializer = Serializer(settings.SECRET_KEY, 3600 * 2)
token = serializer.dumps(info).decode() # 发邮件
send_register_active_email.delay(email, username, token)
return redirect(reverse('user:login'))- worker端配置:
- 将django项目文件复制到另一个文件夹
- 修改tasks.py文件,设置初始化
from celery import Celery
from django.conf import settings
from django.core.mail import send_mail
import os
import django os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'dream.settings')
django.setup() app = Celery('celery_tasks.tasks', broker='redis://127.0.0.1:6379/8') @app.task
def send_register_active_email(email, username, token):
subject = '测试'
message = ""
from_email = settings.EMAIL_FROM
recipient_list = [email]
html_message = '<h1>欢迎{}来到测试</h1>请点击下面链接激活<br><a href="http://127.0.0.1:8000/user/active?token={}">点击此处激活</a>'.format(
username, token)
send_mail(subject, message, from_email, recipient_list, html_message=html_message)- worker端监听
- 进入 worker端的代码的celery_tasks目录下:
- celery -A tasks worker -l info
- win10下可能报错:
- pip install eventlet
- celery -A tasks worker -l info -P eventlet
- 当django启动调用send_mail的时候就会将发邮件的任务交给celery执行
