无法使用我的机器的IP地址运行我的Node.Js应用程序，但可以使用localhost

Question

So I have a node js app set up to listen on port 5050 of my machine:

So when I go to http://localhost:5050/myapp my app loads fine. I am using an express framwork, therefore my listen frame work is as follows:

var server = app.listen(5050, '0.0.0.0', function () {
    console.log("App started on port 5050")
});

I also did a netstat(Am using windows 10 machine) and there are postivly no loopbacks to the local ip address.

However when I execute my machines ip eg. http://192.168.0.231:5050/myapp I keep getting: This site can't be reached

EDIT: I dont think I was being very clear

I have firewall turned off, I have tried without having an IP address specifiedin app.listen. I do not think it is an issue of the code, as when I try with just some simple test app and try run with my IP address, this also times out

Answer 1

Try use listen without ip parameter

var server = app.listen(5050, function () {
   console.log("App started on port 5050")
});

While running a nodejs application, i also faced the same issue as you mentioned. Before my code looks like this.

var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var mongoChat = require('./app/mongo_chat');

var ip = "127.0.0.1";
var port = 3000;
var users = {};
var WhisperChek = false;
var storage=[];
app.use(express.static(__dirname + '/public'));
app.get('/', function (req, res) {
    res.sendfile('index.html');
});
//socket connection
    io.on('connection', function (socket) {
        //console.log('Someone connected!');
        mongoChat.mognolizer(io,socket, users, WhisperChek);
        function updateNicknames() {
            io.emit('nickname', Object.keys(users));
        }
//disconnect socket
        socket.on('disconnect', function (data) {
            if (!socket.Username)return;
            delete users[socket.Username];
            updateNicknames();
        });
    });
http.listen(port,ip, function () {
    console.log('listening on *:3000');
});

But, I removed the var ip="127.0.0.1" from the code and updated the listen function as:

http.listen(port, function () {
        console.log('listening on *:3000');
    });

Now, my application is running both on localhost ie, on localhost:3000 and its also running on my ipaddress ie, on ipaddress:3000 . The problem there is when we give ip as 127.0.0.1 it only runs on the localhost, as ipaddress we use is private and it changes with the change in network connection. Check it once whether it works for you or not.
