如何检查从JavaScript如果加载页面有ASP.NET身份验证cookie？ [英] how to check from JavaScript if loaded page has ASP.NET authentication cookie?

问题描述

看起来JavaScript无法访问http头中的身份验证Cookie（'ASP.NET_SessionId'，'.ASPXFORMSAUTH'）

It looks like JavaScript does not have access to authentication cookies ('ASP.NET_SessionId', '.ASPXFORMSAUTH')

document.cookie对象没有它们。

in the http headers I can see cookies but document.cookie object does not have them.

推荐答案

ASP.NET会话cookie是仅限HTTP（默认情况下）（合理的话）。如果你需要知道用户是否在Javascript中验证，在页面上放置一个HiddenField，并根据你的验证令牌将其值设置为0或1是一个更好的解决方案。

ASP.NET session cookies are HTTP-only by default (and rightfully so). If you need to find out if the user is authenticated in Javascript, putting a HiddenField on the page and setting its value to 0 or 1 based on your authentication token is a much better solution.
