我可以将Node用作HTML应用程序的Web服务器吗？
[英]Can i use node as webserver for html app?
问题描述
I'm sorry to ask such a simple question. 
很抱歉问这样一个简单的问题。 I've been sent files by someone, an index.html file which pulls in a js file within script tags. 我已经被某人发送了一个文件，一个index.html文件，该文件在script标签内插入一个js文件。 I have to start a webserver to get through authentication and view the files (am in dev). 我必须启动一个Web服务器以通过身份验证并查看文件（在开发中是上午）。
In my CLI i have navigated to the directory containing index.html. 在我的CLI中，我已导航到包含index.html的目录。 I have checked with node -v that I have it installed globally (yes, v 8.6). 我已通过node -v检查是否已在全局安装它（是，v 8.6）。 I've run the simple command node and checked my browser at http://localhost:3000 and a few other ports but get no joy. 我已经运行了简单的命令node并在http：// localhost：3000和其他一些端口检查了浏览器，但没有任何乐趣。 I've also tried node index.html but CLI throws an error. 我也尝试了node index.html但是CLI抛出错误。
How do i start the webserver? 如何启动网络服务器？ All the examples online tell me to build a .js file, but this is not an option. 在线上的所有示例都告诉我构建一个.js文件，但这不是一个选择。

Steps to set up a node web server 设置节点Web服务器的步骤
- Create the route folder from your local machine. 从本地计算机创建路由文件夹。
- Go to the command prompt from the project root path. 从项目根路径转到命令提示符。
- Install express using the command npm install express 使用命令npm install express安装express
- Create server.js file 创建server.js文件
- create the folder wwww and create the Index.html inside it. 创建文件夹wwww并在其中创建Index.html 。
server.js server.js
var express = require('express');
var app = express();
app.use(express.static(__dirname + '/www'));
app.listen('3000');
console.log('working on 3000');
Index.html Index.html
<!doctype html
<html>
<head>
<title> my local server </title>
</head>
<body>
<h1> server working </h1>
<p> just put your html,css, js files here and it work on your own local nodejs server </p>
</body>
</html>
Go to the project root path and take the command prompt, then start the server by running the command node server.js 转到项目根路径，并显示命令提示符，然后通过运行命令节点server.js启动服务器。
Then go to the browser and run the url localhost:3000 . 然后转到浏览器并运行url localhost：3000 。
Now you can see the html page will render on your browser. 现在您可以看到html页面将在浏览器中呈现。

Yes, this is possible. 是的，这是可能的。
A very simple example of how to do this would be to create file, let's call it app.js and put this in it: 一个简单的例子就是创建文件，将其命名为app.js并将其放入其中：
const http = require('http'), // to listen to http requests
fs = require('fs'); // to read from the filesystem
const app = http.createServer((req,res) => {
// status should be 'ok'
res.writeHead(200);
// read index.html from the filesystem,
// and return in the body of the response
res.end(fs.readFileSync("index.html"));
});
app.listen(3000); // listen on 3000
Now, run node app.js 现在，运行node app.js
Browse to http://localhost:3000 浏览到http://localhost:3000
There's loads of other npm packages that will help you out do this, but this is the simplest 'pure node' example to literally read index.html and serve it back as the response. 还有很多其他npm软件包可以帮助您完成此任务，但这是从字面上读取index.html并将其作为响应返回的最简单的“纯节点”示例。

Since you don't want to build a backend but just an http server. 由于您不想构建后端，而只是构建http服务器。 I would propose to use an npm package that do just what you need: 我建议使用npm软件包，该软件包可以满足您的需求：
Open a console 打开控制台
npm install http-server -g
Go to your "index.html" folder (in the console) then type: 转到控制台中的“ index.html”文件夹，然后键入：
http-server
Then reach your content in your browser at this address: 然后通过以下地址在浏览器中访问您的内容：
http://localhost:8080

Its very easy to start a server using node js 使用节点js启动服务器非常容易
Create a server.js file, 创建一个server.js文件，
const http = require('http')
const fs = require('fs');
http.createServer(function (req, res) {
fs.readFile('index.html', function(err, data) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(data);
res.end();
});
}).listen(3000);
Run node server.js 运行node server.js
This will even solve your backslash issue by this 这样甚至可以解决您的反斜杠问题
