Comment utiliser Node.js pour créer un serveur web statique ? L'article suivant vous apprendra étape par étape comment utiliser Node.js pour créer un serveur Web statique. J'espère qu'il vous sera utile !
Nous appelons généralement serveur Web statique comme site Web statique, sa principale caractéristique est que tout le contenu du serveur est prêt à l'emploi, aucun traitement supplémentaire n'est requis sur le backend. Lorsque nous envoyons une requête de page Web au serveur statique, le serveur n'a qu'à renvoyer le fichier html correspondant en fonction de notre chemin de requête (URL). html文件就行了。
静态网站是指全部由HTML（标准通用标记语言的子集）代码格式页面组成的网站，所有的内容包含在网页文件中。网页上也可以出现各种视觉动态效果，如GIF动画、FLASH动画、滚动字幕等，而网站主要是静态化的页面和代码组成，一般文件名均以htm、html、shtml等为后缀。—— 百度百科
与静态网站对应的是我们最常见的动态Web服务器，此类服务器最大的特征就是所有资源通常不是以html形式存储的，而是需要后端查询数据，组成网页之后再返回给用户，每个用户看到的内容可能是都不相同的。例如，在Java搭建的Web服务器中，我们可以使用JSP拼接网页，形成特定于用户的页面。
（1）动态网页以数据库技术为基础，可以大大降低网站维护的工作量；
（2）采用动态网页技术的网站可以实现更多的功能，如用户注册、用户登录、在线调查、用户管理、订单管理等等；
（3）动态网页实际上并不是独立存在于服务器上的网页文件，只有当用户请求时服务器才返回一个完整的网页；
（4）动态网页中的“？”搜索引擎一般不可能从一个网站的数据库中访问全部网页，或者出于技术方面的考虑，搜索蜘蛛不去抓取网址中“？”后面的内容，因此采用动态网页的网站在进行搜索引擎推广时需要做一定的技术处理才能适应搜索引擎的要求。
（5）静态网站因为没有和数据库连接，所以要有动态网站的效果就必须制作大量的网页，其中许多网页只能是虚假网页，根本实现不了动态网站的功能。

由于静态服务器不需要后端数据库，所以结构非常简单，非常适合例如文档管理、博客等场景。就以写博客本身而言，我认为静态网站有以下特点：
需要的服务器配置低，最基础的服务器就可以满足大部分人的性能需求；
响应速度快，内容都是现成的html，直接访问即可获得结果；
一个html对应一个url，内容稳定，容易被搜索引擎检索；
制作简单，只需要在服务器搭建完成后，将文件防止指定位置即可；
以上有点都是针对静态博客系统而言的，如果使用纯静态服务器制作一个大型的其他类型网站可能代价比较大。
如果个人希望快速搭建一个静态服务器，可以使用基于Node.js的http-server包，可以在一分钟内完成服务器的搭建，步骤如下：
下载http-server包，记得全局安装
npm i http-server -g
进入服务器文件夹，启动服务器
http-server -a 127.0.0.1 -p 9999
这样服务器就启动了，根目录就是启动服务器命令执行的目录。
访问localhost:9999就可以看到所有的文件了，下面是我的文件内容：
如果我们点击文件名，就会得到对应的文件，例如我们点击*.html，就可以得到网页：
这看起来就像是个FTP
Un site Web statique fait référence à un site Web entièrement composé de pages au format de code HTML (un sous-ensemble du Standard Universal Markup Language), et tout le contenu est inclus dans des fichiers de page Web. Divers effets visuels dynamiques peuvent également apparaître sur les pages Web, tels que des animations GIF, des animations FLASH, des sous-titres déroulants, etc. Les sites Web sont principalement composés de pages et de codes statiques. Généralement, les noms de fichiers sont suffixés par htm, html, shtml, etc. ——Baidu EncyclopediaCorrespondant aux sites Web statiques est notre 🎜serveur Web dynamique🎜 le plus courant. La plus grande caractéristique de ce type de serveur est que toutes les ressources ne sont généralement pas stockées sous forme de
htmlcode>. Au lieu de cela, le backend doit interroger les données, créer une page Web, puis la renvoyer à l'utilisateur. Le contenu que voit chaque utilisateur peut être différent. Par exemple, dans un serveur Web construit avec <code>Java, nous pouvons utiliser JSP pour fusionner des pages Web afin de former une page spécifique à l'utilisateur. 🎜🎜 (1) Les pages Web dynamiques sont basées sur la technologie de base de données, ce qui peut réduire considérablement la charge de travail de maintenance du site Web 🎜🎜 (2) Les sites Web utilisant la technologie des pages Web dynamiques peuvent implémenter plus de fonctions, telles que l'enregistrement des utilisateurs, la connexion des utilisateurs ; , Enquêtes en ligne, gestion des utilisateurs, gestion des commandes, etc. ; 🎜🎜 (3) Les pages Web dynamiques ne sont pas réellement des fichiers Web qui existent indépendamment sur le serveur. Le serveur ne renvoie une page Web complète que lorsque l'utilisateur la demande ; 4) Le "?" dynamique dans la page Web est généralement impossible pour les moteurs de recherche d'accéder à toutes les pages Web à partir de la base de données d'un site Web, ou pour des raisons techniques, les robots de recherche n'explorent pas le contenu après le "?" ainsi sites Web utilisant des pages Web dynamiques Lors de la promotion sur les moteurs de recherche, certains traitements techniques sont nécessaires pour s'adapter aux exigences des moteurs de recherche. 🎜🎜 (5) Les sites Web statiques ne sont pas connectés à la base de données, donc pour avoir l'effet d'un site Web dynamique, un grand nombre de pages Web doivent être produites.

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
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

...//实在太长，就不贴这里了，文末有完整代码}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。
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。
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。
