SharedArrayBuffer、Github页面和DNS

Question

Buon giorno，情况如下：

通过Github页面托管的

• ：https://github.com/ossia/score-web；我将其配置为将其置于域https://ossia.io之后，从而位于address

需要SharedArrayBuffer的

• 应用程序

正如您可以检查的，网站https://ossia.io/score-web返回一个错误：

ReferenceError: SharedArrayBuffer is not defined

从铬检验员所说的：

SharedArrayBuffers (SABs) can be used to construct high-resolution timers. High-resolution timers simplify Spectre attacks on cross-origin resources.

To mitigate security risks across browsers, SharedArrayBuffers are gated behind cross-origin isolated contexts starting with Chrome 92 (July 2021). 

To continue using SharedArrayBuffers, please ensure that this page opts-into cross-origin isolation by setting Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy appropriately.

Note that for each iframe, only the first issue is reported for performance reasons.

是CORS的问题。

如果没有：

• 不得不更改URL
• 必须移出GH页面

Answer 1

我设法用以下库修复了它，该库显然重新加载了页面，并注入了丢失的CORS头：

https://github.com/gzuidhof/coi-serviceworker

我刚加了

<script src="coi-serviceworker.min.js"></script>

到index.html页面服务，网站和它旁边的JS脚本，它起作用了。
