Here's my nodejs server program.这是我的 nodejs 服务器程序。
var express = require('express');
var bodyParser = require('body-parser');
var urlencodedParser = bodyParser.urlencoded({ extended: false });
var mysql = require('mysql');
var $ = require('jquery');
var settings = {
host: 'cgs-devdb.czspzuv6lcaw.us',
database: 'Customer 360',
user: 'cgsadmin',
password: 'cypre55gs'
};
// Express
var app = express();
app.use(express.static(__dirname + '/public'));
app.use(bodyParser.urlencoded({ extended: false}));
app.use(bodyParser.json());
app.get('/dashboard.html', function (req, res) {
res.sendFile( __dirname + "/" + "dashboard.html" );
});
// Get information submitted
app.get('/api/itsm/incident', function(req, res){
var obj = {};
var jsonString = JSON.stringify(req.body);
console.log('body: ' + JSON.stringify(req.body));
console.log(req.body);
var qb = require('node-querybuilder').QueryBuilder(settings, 'mysql', 'single');
// Generating Query
qb.select('*')
.where(req.body)
.get('SM_INCIDENT', function(err,response) {
if (err) return console.error("Uh oh! Couldn't get results: " + err.msg);
console.log("Query Ran: " + qb.last_query());
console.log(response);
res.send(response); // sending back the response to ajax
});
});
// Start server
app.listen(8000);
console.log("API is running on port");
These are the errors I am getting.这些是我得到的错误。
Here is the folder structure of my Node JS project这是我的 Node JS 项目的文件夹结构
I am finding it difficult to get the exact html page because of the scripts are not being included.我发现很难获得确切的 html 页面，因为没有包含脚本。 Help me out in finding the mistake.帮我找出错误。 Thanks !!谢谢 ！！

It looks like you want to change:看起来你想改变：
app.use(express.static(__dirname + '/public'));
to:到：
app.use(express.static(__dirname + '/Web-Content'));
Or just rename the Web-Content folder to public .或者只是将Web-Content文件夹重命名为public 。

It worked, when I changed它起作用了，当我改变时
app.use(express.static(__dirname + '/public'));
To到
app.use(express.static(__dirname + '/'));

const express = require('express');
const path = require('path');
const app = express();
const port = process.env.PORT || 3000;// Heroku will need the PORT environment variable
app.use(express.static(path.join(__dirname, 'build')));
app.get('*', (req, res, next) => {
res.sendFile(path.join(__dirname, 'build', 'index.html'));
console.log(next);
});
app.listen(port, () => console.log(`App is live on port ${port}!`));
// "start": "node server.js",
1. Add this server.js file in your root folder
2. Add this in your package.json file
"scripts": {
"heroku-postbuild": "npm run-script build",
"start": "node server.js",
"dev-server": "node scripts/start.js",
"build": "NODE_PATH=src/ node scripts/build.js",
"test": "NODE_PATH=src/ node scripts/test.js",
"prod": "npm run-script build && serve build"
},
3. Install server package (npm install -g server)
and restart our server`enter code here`
