Question

TL; DR ：尝试使用我的Django应用中的Celery / RabbitMQ任务发送电子邮件时，我从Gmail收到SMTPAuthenticationError，尽管传入的凭据是正确的。在没有Celery的情况下正常发送电子邮件时不会发生这种情况。

您好，

我正在尝试使用我的Django应用程序中的Celery / RabbitMQ异步发送电子邮件给用户。我有以下代码发送电子邮件：

from grad.celery import app
from django.core.mail import EmailMultiAlternatives
from django.template.loader import get_template
from django.template import Context
from grad import gradbase
from time import sleep
from grad import settings

@app.task
def send_transaction_email(student_data, student_email):
    html_email = get_template('grad/student_email.html')
    context = Context({
        'name': student_data['name'],
        'university': student_data['university'],
        'data': student_data,
        'shorturl':  gradbase.encode_graduation_data(student_data)
    })
    msg = EmailMultiAlternatives('Subject Here',
                             'Message Here',
                             'myrealemailaddress@gmail.com',
                             [student_email])
    msg.attach_alternative(html_email.render(context), "text/html")
    msg.send()

当我正常调用该方法时：

tasks.send_transaction_email(entry, stud_email)

电子邮件发送正常，但如果我将调用委托给像这样的Celery任务：

tasks.send_transaction_email.delay(entry, stud_email)

我得到以下追踪：

基本上Gmail无法识别凭据，尽管我在导致崩溃的行之前将它们打印在两行上，但它们是正确的。

有人可以帮助我吗？

尝试在https://security.google.com/settings/security/apppasswords处设置应用密码，并在STMP设置中将其用作密码。

通过django celery
