Node.JS-页面持续运行

Question

So I download Windows binaries from node's site and installed on my Windows 7 machine which is installed fine, when I do:

node --version

It correctly displays its version: v0.6.7

Here is the hello world program:

// app.js
var http = require('http');

http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(8000, "127.0.0.1");

console.log('Server running at http://127.0.0.1:8000/');

And when I do:

node app.js

I get the response fine:

Server running at http://127.0.0.1:8000/

However, when I browser the URL http://127.0.0.1:8000 , the page keeps on running (on status bar it says waiting for 127.0.0.1... ).

Can anybody help me how to make it to output Hello World ?

Answer 1

This is what I get with curl:

$ curl -vv localhost:8000

* About to connect() to localhost port 8000 (#0)
*   Trying ::1... Connection refused
*   Trying 127.0.0.1... connected
* Connected to localhost (127.0.0.1) port 8000 (#0)
> GET / HTTP/1.1
> User-Agent: curl/7.21.4 (universal-apple-darwin11.0) libcurl/7.21.4 OpenSSL/0.9.8r zlib/1.2.5
> Host: localhost:8000
> Accept: */*
> 
< HTTP/1.1 200 OK
< Content-Type: text/plain
< Connection: keep-alive
< Transfer-Encoding: chunked
< 
Hello World
* Connection #0 to host localhost left intact
* Closing connection #0

nothing wrong with it. Try updating node to the latest stable version (but I don't see how it can help) and be sure any process except node is owning the tcp port 8000.

In my mind, this is either one of two things:

1. Node does not recieve the request
2. Node does not respond to the request

To test for either, change your code:

// app.js
var http = require('http');

http.createServer(function (req, res) {
  console.log('got a request');
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(8000, "127.0.0.1");

console.log('Server running at http://127.0.0.1:8000/');

Try again. If node does not get the request, try changing the port to 80 instead of 8000, I had a funny case with firefox blocking non-conventional ports a couple of weeks ago.

Let me know how you go

Answer 3

Have you checked your Anti Virus or Windows Firewall?

Whichever one you use you might want create a temp exception or disable it for a while just to make sure nothing is getting in the way there.

Answer 4

Try changing your listen address to 0.0.0.0. Maybe you're having problems binding to that specific loopback.
