无法读取“ASP.NET_SessionId” javascript中的cookie [英] unable to read "ASP.NET_SessionId" cookies in javascript

问题描述

我在codebind的会话中存储了一些数据，因为

Hi ,I am storing some data in session in codebind as

protected void Page_Load(object sender, EventArgs e)
   {
       Session["kkk"]="kkk";
   }

并尝试在javascript中读取此会话cookie ID

and trying to read this session cookie id in javascript as

<a href="#"  önclick="myname()">
   read cookie here
   </a>

 <script> function myname() {
    alert(document.cookie);

} </script>

但它返回的空饼干？

请帮助

推荐答案

这是设计的。



会话cookie只是服务器用来将请求映射到a的随机标识符特定的会话对象。因此，它不是要从客户端读取，因此cookie设置了 HttpOnly 标志。这是一件好事，因为它可以防止恶意脚本劫持你的会话。



即使你能阅读会话cookie，它也只是一个毫无意义的ID。存储在会话中的值将无法从您的脚本中获得。

This is by design.

The session cookie is just a random identifier which the server uses to map the request to a particular session object. As such, it isn't meant to be read from the client, so the cookie has the HttpOnly flag set. This is a good thing, because it prevents malicious script from hijacking your session.

Even if you could read the session cookie, it's just a meaningless ID. Values stored within the session will not be available from your script.
