Python Tastypie：GET的身份验证和POST的匿名验证

我使用Django/tastypi来管理我的用户集合

是否可以允许匿名用户在API中发布（在某个端点创建新用户时），并限制经过身份验证的用户仅获取自己的用户，而不获取所有用户

谢谢你的帮助。

是的，两者都可以

下面是一个简单的示例，说明如何让经过身份验证的用户只获取自己的用户JSON，而不从所有其他用户获取JSON：（假设您使用的是Django的内置用户基础架构）：

下面是一个简单的示例，说明如何让匿名用户发布帖子来创建新用户（注意：严格来说，这不使用Tastype）

我发现最简单的方法是对我正在使用的身份验证类进行子类化。只要覆盖

is\u authenticated

方法，在方法POST时返回

True

class AnonymousPostAuthentication(BasicAuthentication):
    """ No auth on post / for user creation """

    def is_authenticated(self, request, **kwargs):
        """ If POST, don't check auth, otherwise fall back to parent """

        if request.method == "POST":
            return True
        else:
            return super(AnonymousPostAuthentication, self).is_authenticated(request, **kwargs)

我将验证放在

验证

的子类中，覆盖

是否有效

我和上面Sampson做的一样做GET过滤

这是解决我问题的唯一办法吗？因为，正如你说的“严格来说，这不使用Tastypie”不，这不是唯一的方法；但是，当您阅读代码时，您可以看出解决方案非常简单（大部分是输入验证）。这个想法是，你不必在所有事情上都使用Tastype。有另一种方法可以用Tastypie实现，但它更复杂。更一般地说，如果您只是使用一种技术/软件来解决问题，而没有考虑它是否最适合，或者是否有更好/更简单的方法来解决问题，那么您就有可能遇到金锤反模式：谢谢。工作得很好。我稍微修改了代码，因为我只需要为GET禁用身份验证，并为所有其他方法保留它。
