介绍

¥Introduction

这些类用于关联状态并在整个回调和 promise 链中传播它。它们允许在 Web 请求的整个生命周期或任何其他异步持续时间内存储数据。它类似于其他语言中的线程本地存储。

¥These classes are used to associate state and propagate it throughout callbacks and promise chains. They allow storing data throughout the lifetime of a web request or any other asynchronous duration. It is similar to thread-local storage in other languages.

AsyncLocalStorage 和 AsyncResource 类是 node:async_hooks 模块的一部分：

¥The AsyncLocalStorage and AsyncResource classes are part of the node:async_hooks module:

import { AsyncLocalStorage, AsyncResource } from 'node:async_hooks';const { AsyncLocalStorage, AsyncResource } = require('node:async_hooks');拷贝
