你可以将 JS 对象存储在 SharedArrayBuffer 中吗?

Can you store a JS object in a SharedArrayBuffer?

我需要在客户端应用程序和网络工作者之间共享一个对象,我听说过 SharedArrayBuffers。这就是我想做的。

main.js

let myWorker = new Worker('/worker.js')
let mySab = new SharedArrayBuffer(1024)
let myObj = { foo: 'bar', bar: 'foo' }
// Save 'myObj' to 'mySab'
worker.postMessage(sab)

worker.js

self.onmessage = (e) => {
    let myObj = BLANK // Get 'myObj' from SharedArrayBuffer
}

这可能吗?我见过的 ShareArrayBuffers 示例只在缓冲区中保存数字。感谢您的帮助!

不,SharedArrayBuffers 只存储二进制数据。您只能通过 built-in postMessage 函数发送对象的副本。
