从webWorker访问localStorage [英] Accessing localStorage from a webWorker

问题描述

WebWorker可以访问localStorage吗？

如果不是，为什么不呢？从安全角度来看，它有问题吗？

解决方案

不，localStorage和sessionStorage在webworker流程中都未定义。 >

您必须将 postMessage（）调回Worker的原始代码，并让该代码将数据存储在localStorage中。有趣的是，webworker can 可以使用AJAX调用向/从服务器发送/检索信息，这样可以打开可能性，具体取决于你正在尝试做什么。

Can a WebWorker access the localStorage?

If not why not? Is it problematic from a security stand point?

解决方案

No, localStorage and sessionStorage are both undefined in a webworker process.

You would have to call postMessage() back to the Worker's originating code, and have that code store the data in localStorage.

Interestingly, a webworker can use an AJAX call to send/retrieve info to/from a server, so that may open possibilities, depending on what you're trying to do.
