使用 Javascript 读取会话 ID
问题描述：
是否可以通过javascript读取浏览器会话ID?
Is it by any means possible to read the browser session id using javascript?
答
是的.由于会话 ID 通过 URL (document.location.href) 或通过 cookie (document.cookie) 传输，您可以检查两者是否存在会话 ID.
Yes. As the session ID is either transported over the URL (document.location.href) or via a cookie (document.cookie), you could check both for the presence of a session ID.
