是否有Node.js即用工具(与npm一起安装),可以帮助我通过HTTP将文件夹内容作为文件服务器公开。
例如,如果我有
D:\Folder\file.zip
D:\Folder\file2.html
D:\Folder\folder\file-in-folder.jpg
然后从D:\Folder\node node-file-server.js开始我可以通过
http://hostname/file.zip
http://hostname/file2.html
http://hostname/folder/file-in-folder.jpg
为什么我的节点静态文件服务器丢弃请求?参考一些神秘的
标准node.js静态文件服务器
如果没有这样的工具,我应该使用什么框架?

如果您只需要这些,请尝试以下操作:
const fs = require('fs'),
http = require('http'),
arg = process.argv.slice(2),
rootdir = arg[0] || process.cwd(),
port = process.env.PORT || 9000,
hostname = process.env.HOST || '127.0.0.1';
//tested on node=v10.19.0
http.createServer(function (req, res) {
try {
// change 'path///to/////dir' -> 'path/to/dir'
req_url = decodeURIComponent(req.url).replace(/\/+/g, '/');
stats = fs.statSync(rootdir + req_url);
if (stats.isFile()) {
buffer = fs.createReadStream(rootdir + req_url);
buffer.on('open', () => buffer.pipe(res));
return;
}
if (stats.isDirectory()) {
//Get list of files and folder in requested directory
lsof = fs.readdirSync(rootdir + req_url, {encoding:'utf8', withFileTypes:false});
// make an html page with the list of files and send to browser
res.writeHead(200, {'Content-Type': 'text/html; charset=utf-8'});
res.end(html_page(`http://${hostname}:${port}`, req_url, lsof));
return;
}
} catch (err) {
res.writeHead(404);
res.end(err);
return;
}
}).listen(port, hostname, () => console.log(`Server running at http://${hostname}:${port}`));
function html_page(host, req_url, lsof) {//this is a Function declarations can be called before it is defined
// Add link to root directory and parent directory if not already in root directory
list = req_url == '/' ? [] : [`<a href="${host}">/</a>`,
`<a href="${host}${encodeURI(req_url.slice(0,req_url.lastIndexOf('/')))}">..</a>`];
templete = (host, req_url, file) => {// the above is a Function expressions cannot be called before it is defined
return `<a href="${host}${encodeURI(req_url)}${req_url.slice(-1) == '/' ? '' : '/'}${encodeURI(file)}">${file}</a>`; }
// Add all the links to the files and folder in requested directory
lsof.forEach(file => {
list.push(templete(host, req_url, file));
});
return `
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="content-type" content="text/html" charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Directory of ${req_url}</title>
</head>
<body>
<h2>Directory of ${req_url}</h2>
${list.join('<br/>\n')}
</body>
</html>`
}
使用npm安装express:https://expressjs.com/en/starter/installing.html
在index.html的同一级别创建一个名为server.js的文件,内容如下:
var express = require('express');
var server = express();
server.use(express.static(__dirname));
server.listen(8080);
这将加载index.html文件。如果希望指定要加载的html文件,请使用以下语法:
server.use('/', express.static(__dirname + '/myfile.html'));
如果要将其放置在其他位置,请在第三行设置路径:
server.use('/', express.static(__dirname + '/public'));
CD到包含文件的文件夹,然后使用以下命令从控制台运行节点:
node server.js
浏览到localhost:8080
