CORS是否影响localStorage？ [英] Does CORS affects localStorage?

问题描述

搜索无处不在，没有找到直接的答案。

CORS是否可以使跨域（local）域的localStorage共享成为可能？

在IE8上怎么样？

Searched everywhere and didn't find straight answer.
Does CORS make cross-(sub)domain localStorage sharing possible or not?
And how about on IE8?

推荐答案

否，您无法直接访问其他来源的存储空间，无论CORS设置如何。

No, you cannot directly access another origin's storage, regardless of CORS settings.

不过，您可以使用远程AJAX服务，将您的设置存储在远程域。

You could however have a remote AJAX service that could store your settings on the remote domain.

例如说出您的主要网站 www.maindomain.com 返回标题 Access-Control-Allow-Origin：https：//www.subsite.com

e.g. Say your main website www.maindomain.com returns header Access-Control-Allow-Origin: https://www.subsite.com for its AJAX requests.

然后您的其他网站 www.subsite.com 可以创建一个AJAX请求到例如 https://www.maindomain.com/storage 可检索或保存跨原产地的详细信息。 www.maindomain.com 的本地存储可以在 www.subsite.com 使用。

Then your other website www.subsite.com can make an AJAX request to e.g. https://www.maindomain.com/storage to retrieve or to save details cross-origin. The local storage for www.maindomain.com can be returned as a JSON object in the response for www.subsite.com to use.
