python - 将 Django 电子邮件打印到控制台时出现问题

Question

我不确定我的逻辑有什么问题，但是当我提交表单时，它会在浏览器中呈现 Httpresponse，但不会将电子邮件发布到控制台。我希望 View 功能能够成功打印到控制台。稍后我可能会实现 sendgrid 。在我开始深入研究之前，我只想运行成功的控制台打印!谢谢。

控制台输出:

Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.
[06/Apr/2018 11:15:30] "GET /app01/contact_us/ HTTP/1.1" 200 2880
[06/Apr/2018 11:15:40] "POST /app01/contact_us/ HTTP/1.1" 200 30

settings.py 包括:

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'

Answer 1

作为第一次 Django 应用程序创建者，我正在向后端发送电子邮件，这是错误的。只需添加:

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'

到settings.py......(很多文档只是指向实现这些行)

即使您只是像我想的那样发布到后端，您仍然需要 SMTP 来发送电子邮件内容。 (在将网站投入生产之前测试电子邮件是否成功提交)。

SMTP 选项:
我看到了几个不同的 SMTP 选项。谷歌为我工作是为了测试目的。我计划在投入生产后切换到 Sendgrid。我还没有使用 Sendgrid 的原因是因为我还没有注册域名。使用 sendgrid 进行 SMTP 的要求是拥有注册域，但我还没有。

那么我在项目中添加了什么才能使 Google SMTP 电子邮件发送到控制台后端？
设置.py

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1f72667a727e76737e7b7b6d7a6c6c5f78727e7673317c7072" rel="noreferrer noopener nofollow">[email protected]</a>'
EMAIL_HOST_PASSWORD = 'mypassword'
EMAIL_USE_TLS = True
EMAIL_PORT = 587
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

完成此操作后，登录您的 Gmail 帐户，转至:我的帐户>设置>登录和安全
打开允许不太安全的应用程序。
作为我研究中的旁注，我发现使用 google SMTP 进行这样的离线测试是可以的，但在生产中使用它是非法的。将网站投入生产后，您必须使用不同的 SMTP 服务，例如 SendGrid。此外，您还需要确保删除 EMAIL_BACKEND，因为正如 jpmc26 指出的那样，您不希望将电子邮件数据记录在生产环境中。
