在两个不同的Web浏览器之间共享会话 [英] Sharing session between two different web browser

问题描述

我想制作一个 PHP Web应用程序，其中在同一台PC上一次只能进行一个身份验证会话，即使用 Firefox登录用户A ，但是用户B 无法在同一台PC上使用 IE 登录

I want to make a PHP web application in which on a single PC there can only be one authentication session at a time i.e. User A login using Firefox, but User B cannot login using IE on the same PC

如果我从服务器端询问，则我无法执行Google搜索的浏览器之间的会话共享

Of what i googled session sharing between browsers can not be done if asked from server side

推荐答案

从理论上讲，您可以使用 session_id()和一个数据库条目，尽管安全性很棘手，因为恶意用户可以尝试生成随机会话ID来模仿已登录用户的会话.

Theoretically, you could do this using session_id() and a database entry, although security will be tricky since a malicious user could try generating random session IDs to mimic a logged-on user's session.

会话信息以指定的ID存储在客户端浏览器的cookie中.通过存储该ID和数据的JSON字符串，每当更新时，各种用户都可以共享相同的数据.他们都必须不时轮询服务器，以查看数据是否已更改.

Session information is stored in a cookie in the client's browser, with a specified ID. By storing that ID and a JSON string of the data, whenever it's updated, various users could conceivably share the same data. They'd all have to poll the server once in a while to see if the data has been changed.

但是到那时，您不再需要使用$_SESSION了，因此它已经大大超出了您提出问题的目的.您可以使用常规变量获得相同的行为，这已经是安全性方面的改进.

But at that point, you don't need to use $_SESSION anymore, so it's pretty much defeated the purpose of your question. You can get the same behavior with regular variables, which would already be a security improvement.

简短的回答:不，那不是会议的重点.

Short answer: No, that's not the point of sessions.
