如何在不使用req和res.locals的情况下在NodeJS中实现ThreadLocal变量功能？

const async_hooks = require('async_hooks');

const threadLocalMap = new Map();

const asyncLocalStorage = new async_hooks.AsyncLocalStorage();

async_hooks.createHook({
  init(asyncId, type, triggerAsyncId, resource) {
    const parentContext = asyncLocalStorage.getStore();
    if (parentContext) {
      threadLocalMap.set(asyncId, parentContext);
    }
  },
  destroy(asyncId) {
    threadLocalMap.delete(asyncId);
  }
}).enable();

asyncLocalStorage.run(variable, () => {
  // 在这里可以访问ThreadLocal变量
});

const value = asyncLocalStorage.getStore();
