nodesocket / quote-stream Goto Github PK

I am trying to run it on my local machine for a try-out. The code seems pretty straightforward, so I ran node server.js in command line. Then tried to access localhost:4000/ It returns "Cannot GET /" Am I trying it wrong?

For me, in Google Chrome at least, when I try to use the app the ticker var first gets set to AAPL, but then it gets set to favicon.ico. I would recommend changing '/:ticker' to something like '/symbol/:ticker' or using a traditional parameter like '?symbol=AAPL' and the code will work properly again.

working fine with less then 15 connection
after 15 connection server stop with error events.js on 141

var PORT = 4000;
var FETCH_INTERVAL = 300;
var PRETTY_PRINT_JSON = true;

///
// START OF APPLICATION

var express = require('express');
var http = require('http');
var io = require('socket.io');

var app = express();
var server = http.createServer(app);
var io = io.listen(server);
io.set('log level', 1);

server.listen(PORT);

app.get('/', function(req, res) {
res.sendfile(__dirname + '/index.html');
});

io.sockets.on('connection', function(socket) {
socket.on('ticker', function(ticker) {
track_ticker(socket, ticker);
});
});

function track_ticker(socket, ticker) {
//Run the first time immediately
get_quote(socket, ticker);
//Every N seconds
var timer = setInterval(function() {
get_quote(socket, ticker)
}, FETCH_INTERVAL);
socket.on('disconnect', function () {
clearInterval(timer);
});
}

function get_quote(p_socket, p_ticker) {

http.get({
    //host: 'www.google.com',
    host: 'localhost',
    port: 80,
    //path: '/webapp/info?client=ig&q=' + p_ticker
    path: '/webapp/user/bhavjson.php?check=0&Ses_id=' + p_ticker
}, function(response) {
    response.setEncoding('utf8');
    var data = "";

    response.on('data', function(chunk) {
        data += chunk;
    });

    response.on('end', function() {

        p_socket.emit('quote',data);

    });
});

}

After about 2 min of connectivity to the server, the express app is dumped with this exception:

Error: connect ETIMEDOUT 172.217.6.4:443
    at Object.exports._errnoException (util.js:837:11)
    at exports._exceptionWithHostPort (util.js:860:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1060:14)

Do you think this could be Google dropping the connection?
