在 Django 中使用 Sendgrid 发送电子邮件

Question

我正在尝试使用 Sendgrid 从 Django 应用程序发送电子邮件。我尝试了很多配置，但我的Gmail帐户仍然没有收到任何电子邮件。您可以在下面看到我的配置：

设置.py：

SEND_GRID_API_KEY = 'APIGENERATEDONSENDGRID'
EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = 'mySENDGRIDusername'
EMAIL_HOST_PASSWORD = 'myEMAILpassword' #sendgrid email
EMAIL_PORT = 587
EMAIL_USE_TLS = True
DEFAULT_FROM_EMAIL = 'MYEMAIL' #sendgrig email

视图.py

from django.shortcuts import render
from django.http import HttpResponse
from .forms import ContactForm
from django.core.mail import send_mail
from django.conf import settings
from django.template.loader import get_template


def index(request):
    return render(request, 'index.html')

def contact(request):

    success = False
    form = ContactForm(request.POST)
    if request.method == 'POST':
        name = request.POST.get("name")
        email = request.POST.get("email")
        message = request.POST.get("message")

        subject = 'Contact from MYSITE'

        from_email = settings.DEFAULT_FROM_EMAIL
        to_email = [settings.DEFAULT_FROM_EMAIL]

        message = 'Name: {0}\nEmail:{1}\n{2}'.format(name, email, message)

        send_mail(subject, message, from_email, to_email, fail_silently=True)

        success = True 
    else:
        form = ContactForm()
    context = {
        'form': form,
        'success': success
    }
    return render(request, 'contact.html',context)

你们知道会发生什么吗？我在本地可以收到邮件，在终端也可以看到，但是根本发不出邮件。

在尝试使用 SMTP 设置 Django 的 sendgrid 时，我有点挣扎。对我有用的是以下内容：

设置.py

EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = 'apikey' # this is exactly the value 'apikey'
EMAIL_HOST_PASSWORD = 'sendgrid-api-key' # this is your API key
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
DEFAULT_FROM_EMAIL = 'your-email@example.com' # this is the sendgrid email

我使用了这个配置，运行正常，强烈建议使用环境变量来填充EMAIL_HOST_PASSWORDand DEFAULT_FROM_EMAIL，所以代码如下：

import os # this should be at the top of the file

# ...

EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = 'apikey'
EMAIL_HOST_PASSWORD = os.getenv("EMAIL_HOST_PASSWORD", "")
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
DEFAULT_FROM_EMAIL = os.getenv("DEFAULT_FROM_EMAIL", "")

然后，在发送电子邮件时，我使用了以下代码：

from django.conf import settings
from django.core.mail import send_mail

send_mail('This is the title of the email',
          'This is the message you want to send',
          settings.DEFAULT_FROM_EMAIL,
          [
              settings.EMAIL_HOST_USER, # add more emails to this list of you want to
          ]
)
