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
/**
* 获取zonecontext值策略:
* 1. 找出当前async-resource 有context的async-resources集合;
* 2. 按就近原则, 遍历async-resources集合对应的context;
* 3. 如果context包含key值则返回,如果不包含key值,则继续;
*
* @param key
* @returns {any}
