本文整理匯總了TypeScript中async_hooks.executionAsyncId函數的典型用法代碼示例。如果您正苦於以下問題：TypeScript executionAsyncId函數的具體用法？TypeScript executionAsyncId怎麽用？TypeScript executionAsyncId使用的例子？那麽, 這裏精選的函數代碼示例或許可以為您提供幫助。
在下文中一共展示了executionAsyncId函數的4個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的TypeScript代碼示例。
示例1: setRootContext
setRootContext(key, value) {
log('set:', key, value);
const rootId = async_hooks.executionAsyncId();
if (this.rootMap.has(rootId)) {
const obj = this.rootMap.get(rootId);
this.rootMap.set(rootId, Object.assign({}, obj, {[key]: value}));
} else {
this.rootMap.set(rootId, {[key]: value});
}
log(this.rootMap);
}示例2: get
/**
* 獲取zonecontext值策略:
* 1. 找出當前async-resource 有context的async-resources集合;
* 2. 按就近原則, 遍曆async-resources集合對應的context;
* 3. 如果context包含key值則返回,如果不包含key值,則繼續;
*
* @param key
* @returns {any}
