javascript - HTML5本地存储数据是否按域分开存储

Question

这个问题已经有答案了:

In HTML5, is the localStorage object isolated per page/domain? (6 个回答)

已关闭 10 年前。

我尝试查看有关 HTML5 本地存储的信息，但似乎找不到直接的答案。

本地存储是否像cookies一样基于Domain存储其对象？

如果是这样，我如何从另一个域访问它？

Answer 1

来自the spec :

User agents must throw a SecurityError exception whenever any of the members of a Storage object originally returned by the localStorage attribute are accessed by scripts whose effective script origin is not the same as the origin of the Document of the Window object on which the localStorage attribute was accessed.

除了存储在 localStorage 中的域之外，您无法从任何域访问存储在 localStorage 中的数据。它遵循与 XMLHttpRequest 相同的模型 - “同源策略”。
