I came across a fix. I scrapped my js attempt and created a new php file with the following code:
我遇到了一个修复。我放弃了我的 js 尝试并使用以下代码创建了一个新的 php 文件：
<?php
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'my_token_code') {
echo $challenge;
}
I got this code from the first 10 minutes of this video: https://www.facebook.com/marketingdevelopers/videos/883648801749520/
我从这个视频的前 10 分钟得到了这个代码：https: //www.facebook.com/marketingdevelopers/videos/883648801749520/

That code is node.jscode and should be run on the server not in a <script>tag in your HTML.
该代码是node.js代码，应该在服务器上运行，而不是在<script>HTML中的标记中。
Here's a simple walk through of setting up the messenger bot with node.js: https://github.com/voronianski/simon-le-bottle
这是使用 node.js 设置信使机器人的简单步骤：https: //github.com/voronianski/simon-le-bottle
Essentially you need to make sure you have a host that supports node.js applications and run it as such. It will not work inside of HTML.
本质上，你需要确保你有一个支持 node.js 应用程序的主机并运行它。它不会在 HTML 内部工作。

I just resolved this problem by adding '/webhook' in the callback URL...
我刚刚通过在回调 URL 中添加 '/webhook' 解决了这个问题......

If you're running this as a Node.jsapplication, and you're coming from the The Facebook Quickstart Guidementioned in the question, you'll have to point the webhook URL to [your-server-root]/webhook. Notice this part of the tutorial:
如果您将此作为Node.js应用程序运行，并且您来自问题中提到的 Facebook 快速入门指南，则必须将 webhook URL 指向[your-server-root]/webhook. 注意教程的这一部分：
// Adds support for GET requests to our webhook
app.get('/webhook', (req, res) => {
...
// Responds with the challenge token from the request
res.status(200).send(challenge);
});

@shane
webhook: function(req, res) {
if (req.query['hub.verify_token'] === 'tokentoken') {
res.send(req.query['hub.challenge']);
} else {
res.send('Error, wrong validation token');
}
}
Note sure what exactly you're doing. but this is what I did and it's working.
注意确定你在做什么。但这就是我所做的并且正在起作用。
I've tested using ngrok server as I don't have a domain name and the callback URL is https://werwrwetwtw.ngrok.io/webhook
我已经使用 ngrok 服务器进行了测试，因为我没有域名并且回调 URL 是https://werwrwetwtw.ngrok.io/webhook
Hope this helps!
希望这可以帮助！

Not sure if this help, but the query parameters that FB send are with underscore not dot e.g. :
不确定这是否有帮助，但是 FB 发送的查询参数是下划线而不是点，例如：
- hub_verify_token
- hub_mode
- hub_challenge
- hub_verify_token
- 集线器模式
- hub_challenge
