Node.js: get path from the request

Question

I have a service called "localhost:3000/returnStat" that should take a file path as parameter. For example '/BackupFolder/toto/tata/titi/myfile.txt'.

How can I test this service on my browser? How can I format this request using Express for instance?

exports.returnStat = function(req, res) {  var fs = require('fs'); var neededstats = []; var p = __dirname + '/' + req.params.filepath;  fs.stat(p, function(err, stats) {     if (err) {         throw err;     }     neededstats.push(stats.mtime);     neededstats.push(stats.size);     res.send(neededstats); }); }; 

Answer 1

var http = require('http'); var url  = require('url'); var fs   = require('fs');  var neededstats = [];  http.createServer(function(req, res) {     if (req.url == '/index.html' || req.url == '/') {         fs.readFile('./index.html', function(err, data) {             res.end(data);         });     } else {         var p = __dirname + '/' + req.params.filepath;         fs.stat(p, function(err, stats) {             if (err) {                 throw err;             }             neededstats.push(stats.mtime);             neededstats.push(stats.size);             res.send(neededstats);         });     } }).listen(8080, '0.0.0.0'); console.log('Server running.'); 

I have not tested your code but other things works

If you want to get the path info from request url

 var url_parts = url.parse(req.url);  console.log(url_parts);  console.log(url_parts.pathname); 

1.If you are getting the URL parameters still not able to read the file just correct your file path in my example. If you place index.html in same directory as server code it would work...

2.if you have big folder structure that you want to host using node then I would advise you to use some framework like expressjs

If you want raw solution to file path

var http = require("http"); var url = require("url");  function start() { function onRequest(request, response) {     var pathname = url.parse(request.url).pathname;     console.log("Request for " + pathname + " received.");     response.writeHead(200, {"Content-Type": "text/plain"});     response.write("Hello World");     response.end(); }  http.createServer(onRequest).listen(8888); console.log("Server has started."); }  exports.start = start;
