我正在尝试在 NextJs 中实现 Web Worker,我遵循了他们的示例,但是我无法将 Worker 相对 URL 作为变量传递给new URL(url, baseUrl).
以下代码片段是调用工作者的地方:
import { useEffect, useRef, useCallback } from 'react'
export default function Index() {
const workerRef = useRef()
useEffect(() => {
const workerUrl = '../worker.js';
console.log({
URL: new URL('../worker.js', import.meta.url),
meta: import.meta.url
});
console.log({
URL: new URL(workerUrl, import.meta.url),
meta: import.meta.url
});
workerRef.current = new Worker(new URL('../worker.js', import.meta.url))
workerRef.current.onmessage = (evt) =>
alert(`WebWorker Response => ${evt.data}`)
return () => {
workerRef.current.terminate()
}
}, [])

这应该很简单,但我试过搞乱 aes 组,但没有成功。
我能做的最大事情是离散化 disp 变量,但它不是最优的。
