Here is an image of the error. I developed an application on AngularJS, and when I run node server by using public wifi my application is running fine. However, when I run it on org network/company wifi my application doesn't work. Any help?
server.js code
var express = require("express");
var open = require("open");
var bodyParser = require("body-parser");
var cookieParser = require("cookie-parser");
var fs = require("fs");
var path = require("path");
var auth = require("./api/auth");
//var users = require("./api/users");
var transactions = require("./api/transactions");
//var serviceTypes = require("./api/serviceTypes");
var app = express();
app.use(bodyParser.urlencoded({extended: false}))
app.use(bodyParser.json());
app.use(cookieParser());
app.use(express.static("boilerplate"));
app.use(express.static("./"));
app.listen(3000, function () {
console.log("server is running on port:3000");
open("http://localhost:3000/");
});
app.get("/", function (req, res) {
res.sendFile(path.join(__dirname, "boilerplate/index.html"));
});
app.use("/auth", auth);
//app.use("/users", users);
app.use("/transactions", transactions);
//app.use("/servicetypes", serviceTypes);
server.js
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var session = require('express-session');
var fs = require('fs');
var router = require('./router/main')(app, fs);
var server = app.listen(3000, function(){
console.log('Express server has started on port 3000');
});
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
router/main.js
module.exports = function(app, fs)
{
app.post('/addUser/', function(req, res){
console.log(req.body);
});
}
I use postman tool!! requets param {"password" : "pass","name" : "dltlsdn"}
but... req.body is undefind.... why..??
Reorder the app.use statement. Earlier you were processing the request before passing through the body-parser.
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var session = require('express-session');
var fs = require('fs');
//body parser before routes
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
var router = require('./router/main')(app, fs);
var server = app.listen(3000, function(){
console.log('Express server has started on port 3000');
});
Hope it helped you.
i am trying to get my chat app in node.js/socket.io to work on SSL (https), i am now at the moment i dont get errors when i startup the server but i cant connect anymore.
I googled and tried so much examples but i cant get it to work.
This was my old code (this works in http)
var express = require('express')
, app = express()
, http = require('http')
, server = http.createServer(app)
, io = require('socket.io').listen(server);
server.listen(8080);
app.get('/', function (req, res) {
res.sendfile(__dirname + '/index.html');
});
This is my changed code:
var https = require('https');
var fs = require('fs');
var options = {
key: fs.readFileSync('cert.key'),
cert: fs.readFileSync('cert.crt')
};
var express = require('express')
, app = express();
var server = https.createServer(options);
var io = require('socket.io').listen(server);
server.listen(8080);
app.get('/', function (req, res) {
res.sendfile(__dirname + '/index.html');
});
This is how I created the https server on node. Try it once it is working fine for me .
var port = "80";
var express = require('express')
, app = express()
, http = require('http')
, server = http.createServer(app);
server.listen(port);
var fs = require('fs');
var net = require('net');
var tls = require('tls');
var sslOptions = {
key: fs.readFileSync('public/server.key'),
cert: fs.readFileSync('public/server.crt')
};
tls.createServer(sslOptions, function (cleartextStream) {
var cleartextRequest = net.connect({
port: port, //your port
host: serverStr // your server address
}, function () {
cleartextStream.pipe(cleartextRequest);
cleartextRequest.pipe(cleartextStream);
});
}).listen(443);
I'm trying to use simplewebrtc in my app, I already have a simple nodejs server with express web framework. But to use simpleWebrtc we have to install signal master. I'm looking at the source code for the server.js file in the signal master package but I can't figure out how to combine this server.js with my already existing app.js file. This is basically my app.js
var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var mongoose = require('mongoose');
var favicon = require('serve-favicon');
var bodyParser = require('body-parser');
app.get('/', function(req, res) {
res.sendFile(__dirname + '/index.html');
console.log("connected to index");
});
and this is server.js of signalMaster
/*global console*/
var yetify = require('yetify'),
config = require('getconfig'),
uuid = require('node-uuid'),
crypto = require('crypto'),
fs = require('fs'),
port = parseInt(process.env.PORT || config.server.port, 10),
server_handler = function (req, res) {
res.writeHead(404);
res.end();
},
server = null;
// Create an http(s) server instance to that socket.io can listen to
if (config.server.secure) {
server = require('https').Server({
key: fs.readFileSync(config.server.key),
cert: fs.readFileSync(config.server.cert),
passphrase: config.server.password
}, server_handler);
} else {
server = require('http').Server(server_handler);
}
server.listen(port);
var io = require('socket.io').listen(server);
if (config.logLevel) {
// https://github.com/Automattic/socket.io/wiki/Configuring-Socket.IO
io.set('log level', config.logLevel);
}
etc, etc you can look at the rest by downloading the zip. I thought it would be just replacing server with http, but the server=null doesn't really make sense. All the dependencies are in the directory of the signalMaster unzipped file. I was reading about signalMaster here.
You will need something like this
var os = require('os');
var static = require('node-static');
var http = require('http');
var socketIO = require('socket.io');
var fileServer = new(static.Server)();
var app = http.createServer(function (req, res) {
fileServer.serve(req, res);
}).listen(2013);
var io = socketIO.listen(app);
io.sockets.on('connection', function (socket){
...
socket.on('join', function (message) {
...
}
...
}
i hope this help u
Can I create an Express server listening on both HTTP and HTTPS, with the same routes and the same middlewares?
Currently I do this with Express on HTTP, with stunnel tunneling HTTPS to Express, but I prefer a pure Node solution.
I can do it with this code, but using the handle method that is marked as private:
var express = require( 'express' )
, https = require("https")
, fs = require( 'fs' );
var app = express.createServer();
// init routes and middlewares
app.listen( 80 );
var privateKey = fs.readFileSync( 'privatekey.pem' ).toString();
var certificate = fs.readFileSync( 'certificate.pem' ).toString();
var options = {key: privateKey, cert: certificate};
https.createServer( options, function(req,res)
{
app.handle( req, res );
} ).listen( 443 );
To enable your app to listen for both http and https on ports 80 and 443 respectively, do the following
Create an express app:
var express = require('express');
var app = express();
The app returned by express() is a JavaScript function. It can be be passed to Node’s HTTP servers as a callback to handle requests. This makes it easy to provide both HTTP and HTTPS versions of your app using the same code base.
You can do so as follows:
var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');
var app = express();
var options = {
key: fs.readFileSync('/path/to/key.pem'),
cert: fs.readFileSync('/path/to/cert.pem'),
ca: fs.readFileSync('/path/to/ca.pem')
};
http.createServer(app).listen(80);
https.createServer(options, app).listen(443);
For complete detail see the doc
As a possible update to this question, you might want to check out the changes here for express 3. The change document says:
The return value of express() is a JavaScript Function,
encapsulating everything that makes an Express app tick. This means
you can easily setup HTTP and HTTPS versions of your application by
passing it to node's http.createServer() and https.createServer():
In Express 3, express.createServer() is now express()
Here is a complete example for express 3:
var fs = require('fs')
, https = require('https')
, http = require('http')
, express = require('express')
, keys_dir = 'keys/'
, server_options = {
key : fs.readFileSync(keys_dir + 'privatekey.pem'),
ca : fs.readFileSync(keys_dir + 'certauthority.pem'),
cert : fs.readFileSync(keys_dir + 'certificate.pem')
}
, app = express();
app.configure(function(){
app.use(express.cookieParser());
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.session( { secret: '' } ));
app.use(app.router);
});
app.configure('development',function(){
app.use(express.static(__dirname + '/public'));
app.use(express.errorHandler({dumpExceptions: true, showStack:true}));
app.set('view options', { pretty: true });
});
app.get('/', function(req, res){
res.send('Hello World!');
});
https.createServer(server_options,app).listen(7000);
http.createServer(app).listen(8000);
You can share the implementation via something like:
var register = function (app) {
// config middleware
app.configure({
});
// config routes
app.get(...);
};
var http = express.createServer();
register(http);
http.listen(80);
var https = express.createServer({ key: /* https properties */ });
register(https);
https.listen(443);
You can use express and https in same port.
this works for me.
const express=require('express');
const app=express();
const cors=require('cors');
const path=require("path");
const routes=require('./routes/api');
const routerComplain=require('./routes/api');
const routerstores=require('./routes/api');
const routerstock=require('./routes/api');
const routerreport=require('./routes/api');
const routeritem=require('./routes/api');
const bodyParser=require('body-parser');
const routerRegister=require('./routes/api');
const mongoose=require('mongoose');
var server = require('http').Server(app);
var io = require('socket.io')(server);
require("dotenv").config();
mongoose.connect('mongodb://#################',{ useNewUrlParser: true },(err)=>{
if(!err){
console.log('db connected')
}else{
console.log('error in db')
}
});
mongoose.Promise = global.Promise;
app.use(express.static('public'));
app.use(bodyParser.json());
app.use(cors({credentials: true, origin:'http://localhost:3000'}));
app.use(express.static(path.join(__dirname, "client", "build")))
app.use('/reg',routes);
app.use('/complain',routerComplain);
app.use('/register',routerRegister);
app.use('/stores',routerstores);
app.use('/reports',routerreport);
app.use('/stock',routerstock);
app.use('/items',routeritem);
app.get("*", (req, res) => {
res.sendFile(path.join(__dirname, "client", "build", "index.html"));
});
io.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
})
const port = process.env.port||4000;
server.listen(port,function(){
console.log('now listening for request');
});
If you want to use the traditional two ports, one of the above solutions probably works, but using httpolyglot, you can really easily have http and https on the same port with the same middlewares.
https://github.com/mscdex/httpolyglot
Here's some skeleton code that worked for me:
var express = require('express');
var fs = require('fs');
var httpolyglot = require('httpolyglot');
var app = express();
const options = {
key: fs.readFileSync("/etc/ssl/certs/key"),
cert: fs.readFileSync("/etc/ssl/certs/cer.cer")
};
httpolyglot.createServer(options, app).listen(port);
and if you want http -> https forwarding, you can just add this middleware function before the createServer() call:
app.use(function(req, res, next) {
if (!req.secure ) {
res.redirect (301, 'https://' + req.hostname + ':port' + req.originalUrl);
}
next();
});
This can be set up on a custom port

Be aware that express now support creating Https servers with:
var app = require('express').createServer({ key: ... });
