JavaScript Cookie绝对拒绝删除 [英] JavaScript Cookie absolutely refuses to be deleted

问题描述

这与我的其他问题有关，我在问一个新问题缩小问题的范围，原来的问题变得相当复杂。

This is related to my other question, i'm asking a new question as i've narrowed down the problem and the original question was getting rather convoluted.

总而言之，我有一个拒绝删除的cookie！

In a nutshell, i have a cookie that refuses to be deleted!

我的服务器将Cookie设置为 session = abc; domain = example.com; path = /;

My server sets the cookie "session=abc; domain=example.com; path=/;"

我想在客户端编辑此cookie，所以可以说我想将abc更改为xyz，然后运行以下代码

I want to edit this cookie client-side, so lets say i want to change abc to xyz then i run the following code

document.cookie = "session=xyz; domain=example.com; path=/;"

现在，当我检查Cookie时，我实际上现在拥有以下两个Cookie（前导点）：

Now, when i inspect the cookies i actually now have the following two cookies (note the leading dot):

"session=abc; domain=example.com; path=/;"
"session=xyz; domain=.example.com; path=/;"

我很快放弃了尝试强制我的新cookie删除点，而是选择删除了

I quickly gave up trying to force my new cookie to drop the dot, and instead opted to delete the existing cookie before setting a new cookie.

但是，这：

document.cookie = 'session=; expires=Thu, 01 Jan 1970 00:00:01 GMT;';

这：

document.cookie = 'session=; expires=Thu, 01 Jan 1970 00:00:01 GMT; path=/; domain=example.com;';

两者都不做

怎么做当我什至无法使域名匹配时，我应该删除cookie吗？

How on earth am i supposed to delete a cookie, when i can't even get the domains to match up?

NB

在写这个问题时，事情变得更加复杂！我刚刚注意到，以上行为仅在特定页面上发生，如果我尝试从另一个页面删除服务器的cookie，它就会消失而不会大惊小怪

Whilst writing this question, things have gotten more complicated! I have just noticed that the above behaviour only happens on a specific page, if i attempt to delete the server's cookie from another page it disappears without a fuss

加侮辱性的伤害
这实际上在IE / Edge中按预期工作

To add insult to injury This actually works as expected in IE/Edge

推荐答案

我知道你没有除非有必要，否则不要使用依赖项，但是JS-Cookie是一个极其轻量级，经过广泛测试的库，具有交叉兼容性。

I know you don't want to use dependencies unless necessary, but JS-Cookie is an extremely lightweight, extensively tested library that is cross compatible; it shouldn't affect performance and could be exactly what you're looking for

这是到 GitHub存储库。

干杯！
