在本地主机上运行Node JS服务器 [英] Running Node JS server on localhost
问题描述
例如，我想制作一个非常简单的Web服务器.
I want to make a very simple web server like this for example.
const http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {
'Content-Type': 'text/plain'
});
res.write("Hello!");
res.end();
}).listen(8080);
我将此代码放在WebStorm中并运行了.然后，我将它放在同一目录下的index.html文件中.
I put this code in WebStorm and ran it. Then I put in the same directory index.html file.
<body>
<button id="btn">Click Me</button>
<script src="https://code.jquery.com/jquery-3.2.1.js"></script>
<script src="requester.js"></script>
</body>
我还将requester.js文件放在同一文件夹中.
I also put requester.js file in the same folder.
$('#btn').on("click", function () {
$.get('/', function () {
console.log('Successful.');
});
});
然后我在所有文件所在的文件夹中执行命令live-server.我不知道如何使服务器在本地主机上工作.预先谢谢你.
Then I execute command live-server in this folder where all files are. I don't know how to make the server to work on localhost. Thank you in advance.
推荐答案
您要发送 index.html 文件而不是字符串"Hello":
You want to send your index.html file instead of the string "Hello":
const http = require('http');
const fs = require('fs');
const path = require('path');
http.createServer(function (req, res) {
//NOTE: This assumes your index.html file is in the
// . same location as your root application.
const filePath = path.join(__dirname, 'index.html');
const stat = fs.statSync(filePath);
res.writeHead(200, {
'Content-Type': 'text/html',
'Content-Length': stat.size
});
var stream = fs.createReadStream(filePath);
stream.pipe(res);
}).listen(8080);
取决于将来服务器的复杂性，您可能想研究 express 作为内置服务器的替代方法-在http模块中.
Depending on the complexity of your server in the future, you may want to investigate express as an alternative to the built-in http module.
