Node.js提供了可以用于創(chuàng)建任何HTTP服務(wù)器的客戶端的HTTP模塊。以下是HTTP服務(wù)器的最低限度的結(jié)構(gòu)，它會(huì)在8081端口偵聽。
創(chuàng)建一個(gè)js文件名為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.tjdsmy.cn:8081/');接下來，讓我們?建以下名為index.html的HTML文件在創(chuàng)建server.js的同一目錄下
File: index.html
<html>
<head>
<title>Sample Page</title>
</head>
<body>
Hello World!
</body>
</html>
現(xiàn)在讓我們運(yùn)行server.js看到的結(jié)果：
$ node server.js
驗(yàn)證輸出
Server running at http://www.tjdsmy.cn:8081/
