Node.js提供了可以用于创建任何HTTP服务器的客户端的HTTP模块。以下是HTTP服务器的最低限度的结构,它会在8081端口侦听。
创建一个js文件名为server.js:
var http = require('http');var fs = require('fs');var url = require('url');// Create a serverhttp.createServer( function (request, response) { // Parse the request containing file name var pathname = url.parse(request.url).pathname; // Print the name of the file for which request is made. console.log("Request for " + pathname + " received."); // Read the requested file content from file system fs.readFile(pathname.substr(1), function (err, data) { if (err) { console.log(err); // HTTP Status: 404 : NOT FOUND // Content Type: text/plain response.writeHead(404, {'Content-Type': 'text/html'}); }else{ //Page found // HTTP Status: 200 : OK // Content Type: text/plain response.writeHead(200, {'Content-Type': 'text/html'}); // Write the content of the file to response body response.write(data.toString()); } // Send the response body response.end(); }); }).listen(8081);// Console will print the messageconsole.log('Server running at http://www.landui.com:8081/');
接下来,让我们?建以下名为index.html的HTML文件在创建server.js的同一目录下
File: index.html
<html>
<head>
<title>Sample Page</title>
</head>
<body>
Hello World!
</body>
</html>
现在让我们运行server.js看到的结果:
$ node server.js
验证输出
Server running at http://www.landui.com:8081/
