如何从节点脚本获取 Microsoft Graph API 访问令牌？

为此，我正在使用带有 node/express 的 React，并且我正在学习来自的教程

https://jscomplete.com/learn/1rd-reactful

我的代码/server.js 如下，

import express from 'express';
import React from 'react';
import ReactDOMServer from 'react-dom/server';
import App from '../components/App';


const server = express();
server.use(express.static('dist'));

server.get('/', (req, res) => {
  const initialMarkup = ReactDOMServer.renderToString(<App />);

  res.send(`
    <html>
      <head>
        <title>Sample React App</title>
      </head>
      <body>
        <div id="mountNode">${initialMarkup}</div>
        <script src="/main.js"></script>
      </body>
    </html>
  `)
});



const request = require("request");

const endpoint = "https://login.microsoftonline.com/[My Tenant].onmicrosoft.com/oauth2/token";
const requestParams = {
    grant_type: "client_credentials",
    client_id: "[My ApplicationID]",
    client_secret: "[My Secret]",
    resource: "https://graph.windows.net"
};


request.post({ url:endpoint, form: requestParams }, function (err, response, body) {
    if (err) {
        console.log("error");
    }
    else {
        console.log("Body=" + body);
        let parsedBody = JSON.parse(body);         
        if (parsedBody.error_description) {
            console.log("Error=" + parsedBody.error_description);
        }
        else {
            console.log("Access Token=" + parsedBody.access_token);
            testGraphAPI(parsedBody.access_token);
        }
    }
});

function testGraphAPI(accessToken) {
    request.get({
        url:"https://graph.microsoft.com/v1.0/users",
        headers: {
          "Authorization": "Bearer " + accessToken
        }
    }, function(err, response, body) {
        console.log(body);
    })
}


server.listen(4242, () => console.log('Server is running...'));

我得到了访问令牌，但是当我运行函数 testGraphAPI(accessToken) 来测试它时出现错误。它说

{
  "error": {
    "code": "InvalidAuthenticationToken",
    "message": "Access token validation failure. Invalid audience.",
    "innerError": {
      "request-id": "4abe8022-ebf8-4ae7-b9be-8dd01a460eeb",
      "date": "2019-09-28T08:21:07"
    }
  }
}

我还将我的重定向 url 保存在活动目录中为http://localhost:4242/

有人可以给我有关如何解决此问题的建议，因为我需要使用访问令牌进行进一步的工作。
