I have started a server at local host:8081 as
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/');
After starting the service, I am not able to access internet. please help me with this.

Ok - so there is something I am unable to find and I feel might be fairly simple.
I created a server but forgot to capture the reference sent back in a variable.
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);
Now I am trying to close the server but i don't have a reference to the server.
Is there any way to obtain the reference or close the http server from the nodejs interpreter to avoid using taskmanager to kill the process. Working on Win 7 NodeJS interpreter.
Creating a new one is not allowed.
const server = 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.log("closing the server in 5 seconds");
..
.. setTimeout(() => server.close(), 5000);
..
.. });

You can close it using server.close(); or just kill the process with Ctrl-C.
http.createServer returns the server, so assign the return value to a variable/constant and then you can reference the server.
const server = 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.log("closing the server in 5 seconds");
setTimeout(() => server.close(), 5000);
});
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 have made an example script from Node.js website main page like so:
var http = require('http');
http.createServer(function (req, res) {
console.log("We are connected");
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
Any ideas why each time I connect to 127.0.0.1:1337 (via chromium) I get 2 responses saying "We are connected"??
There are two requests by the browser. One for url / and another for /favicon.ico. Try to output the request url.
console.log(req.url);
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);
