如何使用 node.js 将两个或多个 API 请求组合成一个端点并表达

我是一个相对的初学者.我现在有两个单独的API调用(getPlayerAge和getPlayerRank)，但我试图将这两个调用合并到一个端点(GetBothPlayerAgeAndRank)中，以便两个结果都在一个JSON中.我在ANGLE，TYPESCRIPT，Express，Node.js工作.我怎么做才能得到返回[getPlayerAge，getPlayerRank]？

import * as Promise from 'bluebird';
import { Request, Response, Router } from 'express';

import * as https from 'https';
import * as http from 'http';

import * as apicache from 'apicache';

import { PlayerModule } from '../modules';

const router = Router();
const cache = apicache.middleware;

router.get('/getPlayerAge',  (req: Request, res: Response, next: () => void) => {
    let playerName: string;
    if (!req.query.player) {
        res.json([]);
        next();
    } else {
        playerName = req.query.player;
        PlayerModule.getPlayerAge(playerName)
            .then((results) => {
                if (results.length > 0) {
                    res.json(results[0]);
                } else {
                    res.sendStatus(404);
                }
            })
            .catch((reason) => {
                //console.error(reason);
                res.sendStatus(500);
            })
            .finally(next);
    }
});


router.get('/getPlayerRank', (req: Request, res: Response, next: () => void) => {
    let playerName: string;
    if (!req.query.player) {
        res.json([]);
        next();
    } else {
        playerName = req.query.player;
        PlayerModule.getPlayerRank(playerName)
            .then((results) => {
                if (results.length > 0) {
                    res.json(results[0]);
                } else {
                    res.sendStatus(404);
                }
            })
            .catch((reason) => {
                //console.error(reason);
                res.sendStatus(500);
            })
            .finally(next);
    }
});

export const PlayerRoutes = router;
