我想运行一个非常简单的HTTP服务器。对example.com的每个GET请求都应该得到index.html,但作为一个常规的HTML页面(即,与阅读普通网页时的体验相同)。
使用下面的代码,我可以读取index.html的内容。我如何服务index.html作为一个普通的网页?
var http = require('http');
var fs = require('fs');
var index = fs.readFileSync('index.html');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end(index);
}).listen(9615);
下面的一个建议很复杂,需要我为我想使用的每个资源(CSS、JavaScript、图像)文件写一个get行。
我如何能提供一个单一的HTML页面与一些图像,CSS和JavaScript?
Node.js webserver
没有第三方框架;允许查询字符串;添加尾随斜杠;处理404
创建一个public_html子文件夹,并将所有内容放在其中。
要点:https://gist.github.com/veganaize/fc3b9aa393ca688a284c54caf43a3fc3
var fs = require('fs');
require('http').createServer(function(request, response) {
var path = 'public_html'+ request.url.slice(0,
(request.url.indexOf('?')+1 || request.url.length+1) - 1);
fs.stat(path, function(bad_path, path_stat) {
if (bad_path) respond(404);
else if (path_stat.isDirectory() && path.slice(-1) !== '/') {
response.setHeader('Location', path.slice(11)+'/');
respond(301);
} else fs.readFile(path.slice(-1)==='/' ? path+'index.html' : path,
function(bad_file, file_content) {
if (bad_file) respond(404);
else respond(200, file_content);
});
});
function respond(status, content) {
response.statusCode = status;
response.end(content);
}
}).listen(80, function(){console.log('Server running on port 80...')});

你不需要快递。你不需要联系。Node.js执行http native。你所需要做的就是根据请求返回一个文件:
var http = require('http')
var url = require('url')
var fs = require('fs')
http.createServer(function (request, response) {
var requestUrl = url.parse(request.url)
response.writeHead(200)
fs.createReadStream(requestUrl.pathname).pipe(response) // do NOT use fs's sync methods ANYWHERE on production (e.g readFileSync)
}).listen(9615)
一个更完整的例子,确保请求不能访问基目录下的文件,并进行适当的错误处理:
var http = require('http')
var url = require('url')
var fs = require('fs')
var path = require('path')
var baseDirectory = __dirname // or whatever base directory you want
var port = 9615
http.createServer(function (request, response) {
try {
var requestUrl = url.parse(request.url)
// need to use path.normalize so people can't access directories underneath baseDirectory
var fsPath = baseDirectory+path.normalize(requestUrl.pathname)
var fileStream = fs.createReadStream(fsPath)
fileStream.pipe(response)
fileStream.on('open', function() {
response.writeHead(200)
})
fileStream.on('error',function(e) {
response.writeHead(404) // assume the file doesn't exist
response.end()
})
} catch(e) {
response.writeHead(500)
response.end() // end the response so browsers don't hang
console.log(e.stack)
}
}).listen(port)
console.log("listening on port "+port)
