聊聊怎麼使用Node.js搭建一個靜態Web伺服器

怎麼使用Node.js搭建一個靜態Web伺服器？以下這篇文章就手把教大家使用Node.js搭建靜態Web伺服器的方法，希望對大家有幫助！

一、動靜態伺服器的概念

#1.1 靜態Web伺服器概念

我們通常會稱呼靜態Web伺服器為靜態網站，其主要特徵就是伺服器上的所有內容都是現成的，不需要後端做額外的處理。當我們向靜態伺服器發送網頁請求時，伺服器只需要根據我們的請求路徑（URL），返回對應的html檔案就行了。

靜態網站是指全部由HTML（標準通用標記語言的子集）程式碼格式頁面組成的網站，所有的內容都包含在網頁檔案中。網頁上也可以出現各種視覺動態效果，如GIF動畫、FLASH動畫、滾動字幕等，而網站主要是靜態化的頁面和程式碼組成，一般檔案名稱均以htm、html、shtml等為後綴。 —— 百度百科

與靜態網站對應的是我們最常見的動態Web伺服器，這類伺服器最大的特徵就是所有資源通常不是以html形式儲存的，而是需要後端查詢數據，組成網頁之後再返回給用戶，每個用戶看到的內容可能是都不相同的。例如，在Java建構的Web伺服器中，我們可以使用JSP拼接網頁，形成特定於使用者的頁面。

（1）動態網頁以資料庫技術為基礎，可以大幅降低網站維護的工作量；

（2）採用動態網頁技術的網站可以實現更多的功能，如使用者註冊、使用者登入、線上調查、使用者管理、訂單管理等等；

（3）動態網頁實際上並不是獨立存在於伺服器上的網頁文件，只有當使用者請求時伺服器才返回一個完整的網頁；

（4）動態網頁中的「？」搜尋引擎一般不可能從一個網站的資料庫中存取全部網頁，或者出於技術方面的考慮，搜尋蜘蛛不去抓取網址中「？」後面的內容，因此採用動態網頁的網站在進行搜尋引擎推廣時需要做一定的技術處理才能適應搜尋引擎的要求。

（5）靜態網站因為沒有和資料庫連接，所以要有動態網站的效果就必須製作大量的網頁，其中許多網頁只能是虛假網頁，根本實現不了動態網站的功能。

1.2 靜態Web伺服器的優點

#由於靜態伺服器不需要後端資料庫，所以結構非常簡單，非常適合例如文件管理、部落格等場景。就以寫部落格本身而言，我認為靜態網站有以下特點：

• 需要的伺服器配置低，最基礎的伺服器就可以滿足大部分人的效能需求；

• 回應速度快，內容都是現成的html，直接存取即可獲得結果;

• 一個 html對應一個url，內容穩定，容易被搜尋引擎檢索；

• 製作簡單，只需要在伺服器搭建完成後，將檔案防止指定位置即可；

以上有點都是針對靜態部落格系統而言的，如果使用純靜態伺服器製作一個大型的其他類型網站可能代價比較大。

1.3 快速搭建的途徑

如果個人希望快速建立一個靜態伺服器，可以使用基於Node.js的http- server包，可以在一分鐘內完成伺服器的搭建，步驟如下：

• #http-server#包，記得全域安裝

#

npm i http-server -g

• 進入伺服器資料夾，啟動伺服器

http-server -a 127.0.0.1 -p 9999

這樣伺服器就啟動了，根目錄就是啟動伺服器指令執行的目錄。

訪問localhost:9999就可以看到所有的檔案了，以下是我的檔案內容：

如果我們點擊文件名，就會得到對應的文件，例如我們點擊*.html，就可以得到網頁：

這看起來就像是個FTP伺服器，我們就止步於此了嗎？

非也，一個合格的程式設計師都是要手擼才會快樂！ ！

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。
