I started using PHP a couple of months ago. For the sake of creating a login system for my website, I read about cookies and sessions and their differences (cookies are stored in the user's browser and sessions on the server). At that time, I preferred cookies (and who does not like cookies?!) and just said: "who cares? I don't have any good deal with storing it in my server", so, I went ahead and used cookies for my bachelor graduation project. However, after doin' the big part of my app, I heard that for the particular case of storing user's ID, sessions are more appropriate. So I started thinking about what would I say if the jury asks me why have you used cookies instead of sessions? I have just that reason (that I do not need to store internally information about the user). Is that enough as a reason? or it's more than that? Could you please tell me about advantages/disadvantages of using cookies for keeping User's ID?

感谢大家在StackOverflow!

会话允许您像使用cookie一样存储单独的信息片段,但是数据存储在服务器上而不是客户机上。

这个概念是跨页面加载为web访问者存储持久数据。cookie直接将其存储在客户机上。会话使用cookie作为某种密钥,与存储在服务器端的数据相关联。

最好使用会话,因为实际值对客户端隐藏,您可以控制数据何时过期并失效。如果它完全基于cookie,用户(或黑客)可以操纵他们的cookie数据,然后向您的站点发送请求。

编辑:我不认为使用cookie有任何好处,除了简单。这样看……用户有任何理由知道他们的ID号吗?通常我会说不需要,用户不需要这些信息。在需要知道的基础上,提供信息应该受到限制。如果用户将cookie更改为不同的ID,应用程序将如何响应?这是一个安全隐患。

在会话盛行之前,我基本上有自己的实现。我在客户机上存储了一个唯一的cookie值,并将我的持久数据与该cookie值一起存储在数据库中。然后在页面请求中,我匹配这些值并获得持久数据,而不让客户端控制这些数据。

会话是服务器上与cookie信息相关联的一组信息。如果使用PHP,可以检查会话。保存路径位置,实际上是“查看会话”。 cookie是发送给客户端和从客户端返回的数据片段。cookie通常用于促进会话,因为它告诉服务器哪个客户机处理哪个会话。还有其他方法可以做到这一点(查询字符串魔术等),但cookie可能是最常见的。

I will select Session, first of all session is more secure then cookies, cookies is client site data and session is server site data. Cookies is used to identify a user, because it is small pieces of code that is embedded my server with user computer browser. On the other hand Session help you to secure you identity because web server don’t know who you are because HTTP address changes the state 192.168.0.1 to 765487cf34ert8ded…..or something else numbers with the help of GET and POST methods. Session stores data of user in unique ID session that even user ID can’t match with each other. Session stores single user information in all pages of one application. Cookies expire is set with the help of setcookies() whereas session expire is not set it is expire when user turn off browsers.

我个人同时使用cookie和session。

Cookies只在用户点击“记住我”复选框时使用。而且cookie是加密的,数据只在服务器上解密。如果有人试图编辑cookie,我们的解密器能够检测到它并拒绝请求。

我看到很多网站的登录信息存储在cookie中,任何人都可以简单地在cookie中更改用户的id和用户名来访问任何人的帐户。

谢谢,
