嗨，我目前正在尝试学习如何为我的应用程序创建后端，但是当尝试创建端口3000并使其卷曲时，会产生此错误：

var http = require('http'),
express = require('express');
var app = express();

res.send('<html><body><h1>Hello World</h1></body></html>');
});
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});

Seems your server has not started, try running below steps and see if you are able to connect or not: 似乎您的服务器尚未启动，请尝试按以下步骤运行，看看是否可以连接：
Step 1: Create a directory which will contain all the files related to our app and execute npm init: 步骤1：创建一个目录，其中将包含与我们的应用程序相关的所有文件，并执行npm init：
$ mkdir nodejs-server
$ npm init
Step 2: Install Express as a dependency: 步骤2：安装Express作为依赖项：
$ cd nodejs-server
$ npm install --save express
Step 3: Create default entry point for Node.js ie index.js , inside the same directory we created: 步骤3：在我们创建的同一目录内为Node.js创建默认入口点，即index.js ：
$ cd nodejs-server
$ touch index.js
Copy the content you have shown in your question in index.js : 将您在问题中显示的内容复制到index.js ：
var http = require('http'),
express = require('express');
var app = express();
app.set('port', process.env.PORT || 3000);
app.get('/', function (req, res) {
res.send('<html><body><h1>Hello World</h1></body></html>');
});
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
Step 4: Move to directory nodejs-server and start the app following below command: 步骤4：移至目录nodejs-server并按照以下命令启动应用程序：
$ cd nodejs-server
$ node index.js
