我最近从 Google 收到了以下这条消息。它说我正在使用 SharedArrayBuffers 但我不知道它们是什么。有没有办法确定我是否使用他们所说的我？我正在做的唯一类型的跨域工作是在 iframe 中，我通过不同父域上的 postmessage 调用脚本。但是，我不知道这是否与此有关。
Google systems have recently detected that SharedArrayBuffers (SABs) are used on https://basketball.exposureevents.com/, but COOP and/or COEP headers are not served.
For Web Compatibility reasons Chrome is planning to require COOP/COEP for the use of SABs from Chrome 91 (2021-05-25) onwards. Please implement 'cross-origin-isolated' behavior on your site.
