Mari kita bincangkan tentang cara menggunakan Node.js untuk membina pelayan web statik

Bagaimana untuk menggunakan Node.js untuk membina pelayan web statik? Artikel berikut akan mengajar anda langkah demi langkah cara menggunakan Node.js untuk membina pelayan web statik saya harap ia akan membantu anda!

1 Konsep pelayan dinamik dan statik

1.1 Konsep pelayan web statik

Kami biasanya memanggilnya Pelayan Web Statik ialah tapak web statik Ciri utamanya ialah semua kandungan pada pelayan sudah siap dan tidak memerlukan pemprosesan tambahan pada bahagian belakang. Apabila kami menghantar permintaan halaman web ke pelayan statik, pelayan hanya perlu mengembalikan fail html yang sepadan berdasarkan laluan permintaan (URL) kami.

Tapak web statik merujuk kepada tapak web yang sepenuhnya terdiri daripada halaman format kod HTML (subset daripada Bahasa Penanda Universal Standard) dan semua kandungan disertakan dalam fail halaman web. Pelbagai kesan dinamik visual juga boleh muncul pada halaman web, seperti animasi GIF, animasi FLASH, sarikata bergulir, dsb. Tapak web terutamanya terdiri daripada halaman dan kod statik Secara amnya, nama fail diakhiri dengan htm, html, shtml, dsb. ——Ensiklopedia Baidu

Sepadan dengan tapak web statik ialah pelayan Web dinamik kami yang paling biasa. Ciri terbesar pelayan jenis ini ialah semua sumber biasanya tidak disimpan dalam borang daripada html Sebaliknya, bahagian belakang perlu menanyakan data, membentuk halaman web, dan kemudian mengembalikannya kepada pengguna Kandungan yang setiap pengguna lihat mungkin berbeza. Contohnya, dalam pelayan web yang dibina oleh Java, kita boleh menggunakan JSP untuk menyambung halaman web untuk membentuk halaman khusus pengguna.

(1) Halaman web dinamik adalah berdasarkan teknologi pangkalan data, yang boleh mengurangkan beban kerja penyelenggaraan laman web dengan banyaknya

(2) Laman web yang menggunakan teknologi halaman web dinamik boleh mencapai lebih banyak fungsi , seperti pendaftaran pengguna, log masuk pengguna, tinjauan dalam talian, pengurusan pengguna, pengurusan pesanan, dll.; halaman web yang lengkap;

(4) " dalam halaman web dinamik Secara amnya mustahil untuk enjin carian mengakses semua halaman web dari pangkalan data tapak web, atau disebabkan pertimbangan teknikal, labah-labah carian tidak merangkak Dapatkan kandungan selepas "?" Oleh itu, tapak web yang menggunakan halaman web dinamik perlu melakukan pemprosesan teknikal tertentu untuk menyesuaikan diri dengan keperluan enjin carian semasa mempromosikan enjin carian.

(5) Oleh kerana tapak web statik tidak disambungkan ke pangkalan data, sejumlah besar halaman web mesti dibuat untuk mempunyai kesan tapak web dinamik kebanyakan halaman web ini hanya boleh menjadi halaman web palsu dan tidak dapat merealisasikan fungsi laman web dinamik sama sekali.

1.2 Kelebihan pelayan web statik

Memandangkan pelayan statik tidak memerlukan pangkalan data belakang, strukturnya sangat mudah, sangat sesuai untuk senario seperti pengurusan dokumen dan blog. Berkenaan dengan blog itu sendiri, saya rasa laman web statik mempunyai ciri-ciri berikut:

Memerlukan konfigurasi pelayan yang rendah, dan pelayan yang paling asas boleh memenuhi keperluan prestasi kebanyakan orang; >

• Kelajuan tindak balas adalah pantas, kandungan sudah sedia
, anda boleh mendapatkan hasilnya dengan mengaksesnya terus

• html

  Satu
sepadan dengan satu
• , kandungannya stabil dan mudah untuk diambil semula oleh enjin carian; telah disediakan;

  htmlurl

  Mata di atas semuanya untuk
sistem blog
• statik Mungkin lebih mahal untuk menggunakan pelayan statik tulen untuk mencipta skala besar laman web jenis lain.

1.3 Cara untuk membina dengan cepat

Jika individu ingin membina pelayan statik dengan cepat, mereka boleh menggunakan pakej berdasarkan

, yang boleh selesai dalam satu minit Untuk membina pelayan, langkah-langkahnya adalah seperti berikut:

Muat turun pakej

, ingat untuk memasangnya secara global Node.jshttp-server

• http-server dan masukkan folder Pelayan, mulakan pelayan

npm i http-server -g

Pelayan akan dimulakan, dan direktori akar ialah direktori tempat pelayan mula perintah dilaksanakan.

• Anda boleh melihat semua fail dengan melawati

  Berikut ialah kandungan fail saya:

http-server -a 127.0.0.1 -p 9999

Jika kami mengklik pada nama fail, kami. akan mendapat Fail yang sepadan, sebagai contoh, jika kita mengklik

, kita boleh mendapatkan halaman web: localhost:9999

Ini kelihatan seperti pelayan

Sekiranya kita berhenti di sini? *.html

Tidak, pengaturcara yang berkelayakan hanya akan gembira jika tangannya penuh! !

二、 手撸指南

2.1 框架搭建

我们使用基础的Node.js内置模块即可完成搭建，所以不需要安装额外的工具包。

主要的工作是创建一个服务器目录，结构如下：

web_server/					//根目录
	|- static/
	|	|- css/
	|	|	|- style.css	//样式
	|	|- js/
	|	|	|- common.js	//js
	|	|- index.js			//主页
	|- app.js         		//服务器文件
    |- mime.json			//扩展名配置

2.2 Ctrl+C/V

• app.js

const http = require('http');const fs = require('fs')const url = require('url')const path = require('path')FileMimes = JSON.parse(fs.readFileSync('./mime.json').toString())http.createServer(function (req, res) {
    //1.获取地址
    let pathname = url.parse(req.url).pathname
    pathname = pathname == '/' ? '/index.html' : pathname    let extname = path.extname(pathname)
    //2.fs读取文件
    if (pathname != '/favicon.ico') {
        fs.readFile('./static' + pathname, async (err, data) => {
            if (err) {
                res.writeHead(404, { 'Content-Type': 'text/html;charset="utf-8"' })
                res.end(err.message)
                return
            }
            if (!err) {
                // 3. 针对不同的文件返回不同的内容头
                let mime = FileMimes[extname]
                res.writeHead(200, { 'Content-Type': mime + ';charset="utf-8"' })
                res.end(data)
            }
        })
    }}).listen(8081);console.log('Server running at http://127.0.0.1:8081/');

• mime.json

{ ".323":"text/h323" ,
  ".3gp":"video/3gpp" ,
  ".aab":"application/x-authoware-bin" ,
  ".aam":"application/x-authoware-map" ,
  ".aas":"application/x-authoware-seg" ,
  ".acx":"application/internet-property-stream" ,
  ".ai":"application/postscript" ,
  ".aif":"audio/x-aiff" ,
  ".aifc":"audio/x-aiff" ,
  ".aiff":"audio/x-aiff" ,
  ".als":"audio/X-Alpha5" ,
  ".amc":"application/x-mpeg" ,
	...//实在太长，就不贴这里了，文末有完整代码}

2.3 启动服务器

node ./app.js

启动效果如下：

PS E:\Code\Node\demos\03-static_web_server> node .\app.js   
Server running at http://127.0.0.1:8081/

访问localhost:8081即可得到index.html页面。

2.4 部署服务器（简单过程）

也可以部署到远端的服务器

1. 买服务器

当前流行的服务器提供商包括
- 腾讯云
- 阿里云
- 华为云

不过现在CSDN也来凑热闹了：CSDN云，CSDN好像是基于腾讯云的，价格上都差不多。

2. 买域名（非必须，可以使用IP直接访问）
3. 网站备案
4. 部署
静态网站的部署也非常简单，由于很少出错，而且需要经常启停上传新的博客文件，所以直接复制文件到服务器，然后使用

node ./app.js

就可以了。

三、总结

基于Node.js的静态服务器搭建非常简单，我们可以使用http-server包，也可以基于Node手写代码。

手写代码最核心的内容是mime.json文件，也就是对于不同的文件类型，赋予response不同的返回头。
