使用 nginx 的反向代理节点 js 应用程序出错

Question

我正在关注一本书 Building Bots with node.js

我有一个 node.js 节点 red 和 ngnix 在线的服务器

我从 github 克隆了简单的服务代码

https://github.com/azure-appservice-samples/NodeJS-EmptySiteTemplate

当我尝试在 nginx 中进行代理时出现此错误：

无法获取 /bottest

这是 ngnix 的默认指令

这是我的 server.js 代码：

var express = require('express');
var bodyParser = require('body-parser');
var request = require('request');
var app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.get('/', function (req, res) {
res.send('This is my Facebook Messenger Bot - Whos Off Bot
Server');
});
// for facebook verification
app.get('/webhook', function (req, res) {
if (req.query['hub.verify_token'] ===
'whosoffbot_verify_token') {
res.status(200).send(req.query['hub.challenge']);
} else {
res.status(403).send('Invalid verify token');
}
});
app.post('/webhook', function (req, res) {
var events = req.body.entry[0].messaging;
for (i = 0; i < events.length; i++) {
var event = events[i];
if (event.message && event.message.text) {
if (event.message.text.indexOf('hi') > -1) {
sendMessageWithInitialOptions(event.sender.id);
}
}
}
res.sendStatus(200);
});
function sendMessageWithInitialOptions(recipientId) {
