问题
I found this article where it explains how to set a cookie using only HTML.
He use http-equiv attribute on the <meta> in the <head> of an HTML document:
<meta http-equiv="set-cookie" content="___________">
Now I have read about HTML < meta> http-equiv Attribute but I could not understand how to use it for set a cookie.
Someone can explain to me if you can use this method for set cookie or that guide is just a joke?
I tried this but HolidayGlaze cookie has not been saved.
<meta http-equiv="set-cookie" content="HolidayGlaze=Good%20yummies; expires=Sat, 25-Nov-2023 12:00:00 GMT; domain=.example.com; path=/; secure; httponly;">
P.S. I read also about Differences Between HTML 4.01 and HTML5 syntax so my question is about the correct syntax for HTML5.
回答1:
You used to be able to set cookies using a mata tag, however browsers are moving away from that in favour of HTTP headers, or document.cookie.
If you try to set a cookie using meta tags in Chrome, you will get a warning and/or error (Depending on your version). The feature has been deprecated in M63, and completly removed in M65.
[Deprecation] Setting cookies via
<meta http-equiv='Set-Cookie' ...>no longer works, as of M65. Consider switching todocument.cookie = ..., or toSet-CookieHTTP headers instead. See https://www.chromestatus.com/feature/6170540112871424 for more details.
Blocked setting the
Example cookie; path=/; expires=Friday, 24-Mar-18 10:00:00 GMTcookie from a<meta>tag.
I would imagine that other browsers also have this feature deprecated/removed, or will follow suit shortly with chrome.
You can read more about the deprecation of this feature here: https://bugs.chromium.org/p/chromium/issues/detail?id=767813

Don't set cookies in HTML with meta http-equiv="set-cookie". It's outdated and has no effect in modern browsers that follow the current HTML5 standard (it's non-conforming in HTML5).
