【node开发】node简易服务器一分钟搞定

var http = require(‘http‘); //用来启服务
var fs = require(‘fs‘); //用来读取文件
var root = __dirname //你本地放index.html页面的文件路径
console.log(root)
//开启服务
var server = http.createServer(function(req, res) {
    var url = req.url;
    console.log(url)
    var file = root + url;
    redfile(file, req, res)
}).listen(8088); //端口号
function redfile(url, req, res) {
    let contentType = ‘text/html;charset="utf-8"‘
    if (/\.html$/.test(url)) {
        contentType = ‘text/html;charset="utf-8"‘
    } else if (/\.css$/.test(url)) {
        contentType = ‘text/css; charset=utf-8‘
    } else if (/\.js$/.test(url)) {
        contentType = ‘application/javascript; charset=utf-8‘
    } else if (/\.jpg$/.test(url)) {
        contentType = ‘image/jpg‘
    } else if (/\.png$/.test(url)) {
        contentType = ‘image/png‘
    } else if (/\.ico$/.test(url)) {
        contentType = ‘image/png‘
    }
    fs.readFile(url, function(err, data) {
        if (err) {
            res.writeHeader(404, {
                ‘content-type‘: ‘text/html;charset="utf-8"‘
            });
            res.write(‘<h1>404错误</h1><p>你要找的页面不存在</p>‘);
            res.end();
        } else {
            res.writeHeader(200, {
                ‘content-type‘: contentType
            });
            res.write(data); //将index.html显示在客户端
            res.end();
        }
    })
}
console.log(‘8088端口服务器开启成功‘);
