推荐答案

好吧，您可以使用cookie并将其存储在该人的机器上，但是如果他们使用另一台机器.

从本质上讲，除非a)他没有注册或b)您首先让他登录，否则您实际上无法控制用户的操作.登录后，可以使用任何数量的机制来限制访问.

Well, you could use a cookie and store it on the person''s machine, but that could be defeated if they use another machine.

Essentially you can''t really control what a user does unless a) he''s not registered or b) you make him log in first. Once logged in, any number of mechanisms could be used to restrict acess.
