Getting Device ID using JQuery or Javascript
提问by Salman
Is there a way to get the device's unique id using JQuery/JavaScript.
有没有办法使用 JQuery/JavaScript 获取设备的唯一 ID。
I know one can detect the user agent and type of device that is being used but that is not required. I need to know the unique id that is being used.
我知道可以检测正在使用的用户代理和设备类型，但这不是必需的。我需要知道正在使用的唯一 ID。
Having said that I also know that browser is the least priviliged application running on the machine and it should be able to get that id.
话虽如此，我也知道浏览器是机器上运行的特权最低的应用程序，它应该能够获得该 ID。
But still asking if there is a way?
但是还是问有没有办法？

Not possible as far as I know.
据我所知不可能。
I believe it's a security issue. Your device ID is very sensitive information that you wouldn't want just any website being able to capture.
我相信这是一个安全问题。您的设备 ID 是非常敏感的信息，您不希望任何网站都能捕获这些信息。

It's not possible (without any hackery at least) to physically distinguish the computers accessing a web site without the permission of their owners. You can store a cookie to identify the machine when it visits your site again but the key is that the user is in control, and rightly so.
在未经所有者许可的情况下，不可能（至少在没有任何黑客技术的情况下）从物理上区分访问网站的计算机。您可以存储一个 cookie 以在机器再次访问您的网站时对其进行识别，但关键是用户处于控制之中，这是正确的。
