异步获得数据，保证同一时间多个相同的请求只会实际执行一个
安装
npm install @leizm/async-cache-getter --save使用
import AsyncCacheGetter from "@leizm/async-cache-getter";
const cache = new AsyncCacheGetter({ timeout: 10000 });
// xxxx 用于区别不同的请求操作，相同的请求其名称应该一致
const ret = await cache.get("xxxx", async () => {
return 123456;
});
// 返回结果：123456性能
