解析 Django 中的 AnonymousUser

Question

当我使用 Django 创建发送 email 表单时遇到一些问题。 问题是当我点击联系表单中的发送按钮时。 我看到了这个问题。

settings.py 脚本在这里：

当我将 go 访问我的 google 帐户以允许从此处使用我的帐户访问我的应用程序时， google 不太安全我看到此设置不再可用。 请帮我。 太感谢了...

Answer 1

简单的拼写错误。

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = '<youremail>@gmail.com'
EMAIL_HOST_PASSWORD = ''
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_USE_SSL = False

Host，不是hosts ，这里没有复数。

它被拒绝，因为配置错误。

它找不到EMAIL_HOST_USER ->

尝试使用webmaster@localhost连接到 google，如上所示 ->

显然谷歌拒绝它。

笔记

Gmail 不允许您只从任何服务器发送电子邮件。 你必须允许它。
