实施投票系统，无需注册 [英] Implementing a voting system without requiring registration

问题描述

我想在我的网站上实施投票系统，而不必强制他们创建帐户。

I'd like to implement a voting system on my site, without having to force them to create an account. They would ultimately be voting up/down a piece of content which has a unique ID.

• 我知道我可以在表格中存储条目IP / ID，但如果有多个用户来自同一个IP，那该怎么办？


• 有没有办法唯一标识访问者而不绑定他们的外部ip？ li>
  
• 如果创建了GUID，则将其存储在该计算机上的cookie中，以后可以在同一台计算机上检索相同的IP吗？不同的IP？

对这些问题的任何想法，或任何洞察更好的方法将非常感激。 b $ b

Any thoughts on these questions, or any insight to a better approach would be greatly appreciated.

推荐答案

是的，你可以使用一个cookie，并将到期日设置为未来;

Yes, you could use a cookie and set the expiration very far into the future; however, there is nothing stopping anyone from clearing their cache and voting again.

您最好的选择是使用cookie，不允许来自同一IP的投票15分钟的对方...没有注册，这是你能做的最好的。

Your best bet, is to use the cookie and don't allow votes from the same IP within 15 minutes of each other... without registration thats the best you can do.
