MessageChannel 类
worker.MessageChannel
类的实例代表异步的双向通信通道。
MessageChannel
没有自己的方法。
new MessageChannel()
产生具有 port1
和 port2
属性的对象,其引用链接的 MessagePort
实例。
const { MessageChannel } = require('node:worker_threads');
const { port1, port2 } = new MessageChannel();
port1.on('message', (message) => console.log('received', message));
port2.postMessage({ foo: 'bar' });
// 从 `port1.on('message')` 监听器打印 received { foo: 'bar' }
Instances of the worker.MessageChannel
class represent an asynchronous,
two-way communications channel.
The MessageChannel
has no methods of its own. new MessageChannel()
yields an object with port1
and port2
properties, which refer to linked
MessagePort
instances.
const { MessageChannel } = require('node:worker_threads');
const { port1, port2 } = new MessageChannel();
port1.on('message', (message) => console.log('received', message));
port2.postMessage({ foo: 'bar' });
// Prints: received { foo: 'bar' } from the `port1.on('message')` listener
