请帮帮我，我刚开始学习noode.js，但我不知道如何在从localhost访问时在URL中隐藏扩展，我已经在node.js 中为其编写了代码
var http = require('http');
var fs = require('fs');
const port = 5050
var url = require('url');
const server = http.createServer(function (req, res) {
var q = url.parse(req.url, true);
var filename = "." + q.pathname;
console.log(q);
fs.readFile(filename, function(err, data) {
if (err) {
res.writeHead(404, {'Content-Type': 'text/html'});
return res.end("404 Not Found");
}
else if(filename == './getmoved.html')
{
res.writeHead(301, {'Content-Type': 'text/html'});
res.write(data);
}
else
{
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(data);
}
return res.end();
});
}).listen(5050);
当我在web浏览器中打开URL时http://localhost:5050/index，它应该打开index.html
通常，您最好使用Web服务器作为节点，如Express.js。但出于教育目的，我会尝试以下方法。
在server.js文件旁边创建一个名为public的文件夹，并添加以下三个文件：
- 404.html
- index.html
- otherpage.html
404.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>404</title>
</head>
<body>
<p>Oops! Page not found...</p>
</body>
</html>
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Index page</title>
</head>
<body>
<p>This is the index page</p>
</body>
</html>
otherpage.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<p>The other page</p>
</body>
</html>
最后，节点web服务器server.js:
const util = require('util');
const http = require('http');
const url = require('url');
const path = require('path');
const fs = require('fs');
// Promisify some functions so async/await syntax can be used
const fsReaddir = util.promisify(fs.readdir);
const fsReadFile = util.promisify(fs.readFile);
const port = 5050
// Define a folder to store the html files
const publicDir = path.join(__dirname, 'public');
const server = http.createServer(async function (req, res) {
// Read the filenames in your public folder
const allFiles = await fsReaddir(publicDir);
// Optionally filter out any files with another extension than html
const htmlFiles = allFiles.filter(fileName => /.html$/.test(fileName))
// Parse the requested url
const q = url.parse(req.url, true);
console.log('Requested: ' + q.pathname);
// If no path is given, default to index.html
if(q.pathname === '/') {
console.log('Falling back to index')
const data = await fsReadFile(path.join(publicDir, 'index.html'));
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(data.toString());
res.end();
return;
}
// Loop through all html files
for(const htmlFile of htmlFiles) {
const requestedPath = path.join(publicDir, q.pathname) + '.html';
const actualPath = path.join(publicDir, htmlFile);
// Check for a matching file
if(requestedPath === actualPath) {
console.log('Found match :-)');
// It did match, so read the data of the file and respond
const data = await fsReadFile(requestedPath);
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(data.toString());
res.end();
return;
}
}
console.log('Page not found...');
// No mathces were found, so respond with 404
const data = await fsReadFile(path.join(publicDir, '404.html'));
res.writeHead(404, {'Content-Type': 'text/html'});
res.write(data);
res.end();
}).listen(port);
