Django AUTH_PASSWORD_VALIDATORS 检查符号和其他要求

Question

是否可以验证密码要求，例如：

• 一个大写字母
• 两个符号

使用 Django 内置的密码管理？例如这些：

django.contrib.auth.password_validation.UserAttributeSimilarityValidator
django.contrib.auth.password_validation.MinimumLengthValidator
django.contrib.auth.password_validation.CommonPasswordValidator
django.contrib.auth.password_validation.NumericPasswordValidator

我发现以下 Python 包可以实现我想要的功能，但我想知道它是否可以在本地完成：

https://pypi.org/project/django-password-validators/

谢谢！

您可以编写自己的验证器\nDjango\xe2\x80\x99s 密码验证器有一个相当小的接口。他们必须实现两种方法：

\n

validate(self, password, user=None)如果密码有效，则必须返回 None；如果密码无效，则必须引发 ValidationError 并显示错误消息。您必须能够处理 None 的用户 - 如果这意味着您的验证器可以\xe2\x80\x99t 运行，则返回 None 不会出现错误。在大多数情况下，您甚至不需要用户验证密码（更适合我们想要防止密码重复使用的情况）\nget_help_text()必须提供一些帮助文本来向用户解释密码要求。

OPTIONS中的任何项目AUTH_PASSWORD_VALIDATORS将传递给构造函数。所有构造函数参数都应该有一个默认值。
