我开始使用nodejs。到目前为止，我可以使用app.js节点应用程序打开网页index.html。
来自http://blog.kevinchisholm.com/javascript/node-js/making-a-simple-http-server-with-node-js-part-ii/的示例：
//step 1) require the modules we need
var
http = require('http'),//helps with http methods
path = require('path'),//helps with file paths
fs = require('fs');//helps with file system tasks
//a helper function to handle HTTP requests
function requestHandler(req, res) {
var
content = '',
fileName = path.basename(req.url),//the file that was requested
localFolder = __dirname + '/public/';//where our public files are located
//NOTE: __dirname returns the root folder that
//this javascript file is in.
if(fileName === 'index.html'){//if index.html was requested...
content = localFolder + fileName;//setup the file name to be returned
//reads the file referenced by 'content'
//and then calls the anonymous function we pass in
fs.readFile(content,function(err,contents){
//if the fileRead was successful...
if(!err){
//send the contents of index.html
//and then close the request
res.end(contents);
} else {
//otherwise, let us inspect the eror
//in the console
console.dir(err);
};
});
} else {
//if the file was not found, set a 404 header...
res.writeHead(404, {'Content-Type': 'text/html'});
//send a custom 'file not found' message
//and then close the request
res.end('<h1>Sorry, the page you are looking for cannot be found.</h1>');
};
};
//step 2) create the server
http.createServer(requestHandler)
//step 3) listen for an HTTP request on port 3000
.listen(3000);
但我不知道是否可以打开使用相同app.js的不同网页。它必须是可能的。但是如何修改上面的代码？
问题：
如何修改上面的代码使用app.js能够打开index.html和其他页面web index2.html？ index.html的内容与index2.html不同，但两者都使用相同的app.js
