The server needs to be installed: n ode
Then create the app.js file with the following code
const http = require('http');
const url = require('url');
const path = require('path');
const fs = require('fs');
// 以上是系统命令，不需下载
// npm install mime 下载插件，解析文件类型，作用是防止低版本浏览器无法识别文件类型而导致的错误
const mime = require('mime');
// 创建服务器
const app = http.createServer();
// 服务器请求事件
app.on('request', (req, res) => {
// 获取用户请求路径
let pathname = url.parse(req.url).pathname;
pathname = pathname == '/' ? '/index.html' : pathname;
// 将用户请求的路径转换为服务器盘符实际路径
//如：c:\test\demo\index.html
let realpath = path.join(__dirname, 'public' + pathname);
// 解析文件类型
let type = mime.getType(realpath);
// 读取文件
fs.readFile(realpath, (error, result) => {
if (error != null) {
res.writeHead(400, {
'content-type': 'text/html;charset=utf8'
})
res.end('文件读取失败!')
// 退出
return;
}
// 设置文件类型
res.writeHead(200, {
'content-type': type
})
// 输出
res.end(result)
})
})
// 设置端口号3000并进行监听
app.listen(3000);
console.log("服务器启动成功！");After the file is written, use the PowerShell command line to switch to the directory where the app.js file is located
node app.js
PowerShell output----the server started successfully! The deployment is complete
, and then you can enter in the browser: localhost:3000 (or 127.0.0.1:3000) to access your index.html file.
