如何在express js中将多个请求合并为一个请求对象？

const express = require('express');
const asyncRouter = require('express-async-router').AsyncRouter;
const app = express();
const router = asyncRouter();

const mergedRequest = {
  data: []
};

const mergeRequests = async (req, res, next) => {
  // 发起多个请求
  const request1 = fetch('https://api.example.com/request1');
  const request2 = fetch('https://api.example.com/request2');
  const request3 = fetch('https://api.example.com/request3');

  // 等待所有请求完成
  const [response1, response2, response3] = await Promise.all([request1, request2, request3]);

  // 将请求结果存储到请求对象中
  mergedRequest.data.push(response1);
  mergedRequest.data.push(response2);
  mergedRequest.data.push(response3);

  next();
};

router.get('/merged-request', mergeRequests, (req, res) => {
  res.json(mergedRequest);
});

app.use(router);
