i am new to Node.js. i followed the tutorial and typed the following
var sys = require("util"),
http = require("http");
http.createServer(function(request, response) {
response.sendHeader(200, {"Content-Type": "text/html"});
response.write("Hello World!");
response.close();
}).listen(8080);
sys.puts("Server running at http://localhost:1331/");
but when i go to my browser and type the url i.e. http://localhost:1331
it is failed to open th erequested URL
getting the following in cmd when browse the URL
TypeError: Object #<ServerResponse> has no method 'sendHeader'
at Server.<anonymous> (D:\node_js\hello.js:11:14)
at Server.emit (events.js:70:17)
at HTTPParser.onIncoming (http.js:1511:12)
at HTTPParser.onHeadersComplete (http.js:102:31)
at Socket.ondata (http.js:1407:22)
at TCP.onread (net.js:354:27)
It looks like you followed an out of date tutorial. The Node API has since changed. Try this example:
var http = require('http');
http.createServer(function (request, response) {
response.writeHead(200, {'Content-Type': 'text/html'});
response.end('Hello World\n');
}).listen(1331);
console.log('Server running at http://127.0.0.1:1331/');
It looks like you're listening on port 8080. Either change your URL or the port number you're passing into listen().

I have just started exploring node.js. Have installed msi file on my windows server. My code below returns me expected output in command window
var http = require("http");
http.createServer(function (request, response) {
// Send the HTTP header
// HTTP Status: 200 : OK
// Content Type: text/plain
response.writeHead(200, {'Content-Type': 'text/plain'});
// Send the response body as "Hello World"
response.end('Hello World\n');
}).listen(8081);
// Console will print the message
console.log('Server running at `http://127.0.0.1:8081/`');
But when i type http://127.0.0.1:8081/ in my browser i dont get any output. When i see console i get below error
Failed to load resource: the server responded with a status of 403 (Forbidden)
What i wrong and how to fix? I am following this link
probably like my current PC, your's too must be running McAfee or some other program is already using port 8081, you got two options:
stop McAfee or the other program running on that port
listen to a different port on your node server
var http = require("http");
http.createServer(function (request, response) {
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('Hello World\n');
}).listen(300);
console.log('Server running at http://127.0.0.1:300/');
I changed it to 300 from 8081 and it worked.
http://127.0.0.1:300/ this url gives the desired output.
I am stumped.
I have a node js server running on a subdomain.
Every time i try to access it from a browser i get ERR_CONNECTION_REFUSED error.
Here is my server code
const http = require('http');
http.createServer( function (request, response){
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('Hello World\n');
}).listen(8124, "my-server-ip");
console.log('Server running at http://127.0.0.1:8124/');
Additional Information:
I am running a VPS with Hostgator.
The subdomain shares an IP with main domain; something like 412.x.xx.xxx .
insert console log inside create server function. Then you can identify error for this. Also you can use error response.
const http = require('http');
http.createServer( function (request, response){
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('Hello World\n');
console.log('Server running at http://127.0.0.1:8124/');
}).listen(8124, "my-server-ip");
I'm following along in a MongoDB course and came to a basic Node Hello world server tutorial:
Basically it just displays Hello World on localhost:8000
So I typed out the code below and when I tried to run it, ran into the following error:
var http = require('http');
var server = http.createServer(function (request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
response.end("Hello, World"\n);
});
server.listen(8000);
console.log("Server running at http://localhost:8000");
If I remove the \n it will work fine, just curious as to how does the teacher get his to work with it and no errors?
It's just a typo. It should be: response.end("Hello, World\n");.
I'm following the node.js tutorial in here,
http://net.tutsplus.com/tutorials/javascript-ajax/learning-serverside-javascript-with-node-js/
this is the code,
var sys = require("sys"),
http = require("http");
http.createServer(function(request, response) {
response.sendHeader(200, {"Content-Type": "text/html"});
response.write("Hello World!");
response.close();
}).listen(8080);
sys.puts("Server running at http://localhost:8080/");
in here, it says run like this url,
server's ip:8080/
but if i do this,
it just shows, cannot connect to this url.
i opened 8080 port in the server.
===========================
I'm assuming something is screwed up with codeigniter url helper...
The tutorial may be using an incorrect or deprecated method. Replace
response.sendHeader(200, {"Content-Type": "text/html"});
with
response.writeHead(200, {"Content-Type": "text/html"});
and
response.close();
with
response.end();
I Agree with the answer of Third .... make those changes and if it is local use this URL
http://127.0.0.1:8080/
But
If you are running your server not on localmachine but on something like webserver(AWS), You have to let the security of AWS firewall to allow the port to be public on the internet and also remember to use the AWS instance URL
http://AWSinstanceURL:portno/
Use this one
//Lets require/import the HTTP module
var http = require('http');
//Lets define a port we want to listen to
const PORT=8080;
//We need a function which handles requests and send response
function handleRequest(request, response){
response.end('It Works!! Path Hit: ' + request.url);
}
//Create a server
var server = http.createServer(handleRequest);
//Lets start our server
server.listen(PORT, function(){
//Callback triggered when server is successfully listening. Hurray!
console.log("Server listening on: http://localhost:%s", PORT);
});
Now open http://localhost:8080 and u will get your result.
On nodejs.org socket.setTimeout, it says
When an idle timeout is triggered the socket will receive a 'timeout' event but the connection will not be severed.
But when I test code like this:
var http = require('http');
server = http.createServer(function (request, response) {
request.socket.setTimeout(500);
request.socket.on('timeout', function () {
response.writeHead(200, {'content-type': 'text/html'});
response.end('hello world');
console.log('timeout');
});
});
server.listen(8080);
The socket is closed immediately after timeout, and no data is replied to the browser. Which is quite different from the document. Is this a bug or is there any tricks dealing socket under http module?
The documentation is indeed correct, however it looks like the http module adds a 'timeout' listener which calls socket.destroy(). So what you need to do is get rid of that listener by calling request.socket.removeAllListeners('timeout').
So your code should look like:
var http = require('http');
server = http.createServer(function (request, response) {
request.socket.setTimeout(500);
request.socket.removeAllListeners('timeout');
request.socket.on('timeout', function () {
response.writeHead(200, {'content-type': 'text/html'});
response.end('hello world');
console.log('timeout');
});
});
server.listen(8080);
