使用 postMessage() 传输
\Transferring with postMessage()
可以使用 <MessagePort> 传输 <ReadableStream> 实例。
\A <ReadableStream> instance can be transferred using a <MessagePort>.
const stream = new ReadableStream(getReadableSourceSomehow());
const { port1, port2 } = new MessageChannel();
port1.onmessage = ({ data }) => {
data.getReader().read().then((chunk) => {
console.log(chunk);
});
};
port2.postMessage(stream, [stream]);
