"Socket hang up" error during request

I try to make a GET request to some site (not mine own site) via http module of node.js version 0.8.14. Here is my code (CoffeeScript):

options = 
        host: 'www.ya.ru'
        method: 'GET'
    req = http.request options, (res) ->
        output = ''
        console.log 'STATUS: ' + res.statusCode
        res.on 'data', (chunk) ->
            console.log 'A new chunk: ', chunk
            output += chunk

        res.on 'end', () ->
            console.log output
            console.log 'End GET Request'

    req.on 'error', (err) ->
        console.log 'Error: ', err
    req.end()

I get the following error during this operation: { [Error: socket hang up] code: 'ECONNRESET' }. If I comment the error handler my application is finished with the following error:

events.js:48
    throw arguments[1]; // Unhandled 'error' event
    ^
Error: socket hang up
    at createHangUpError (http.js:1091:15)
    at Socket.onend (http.js:1154:27)
    at TCP.onread (net.js:363:26)

I try to find out solution on the internet but still hasn't found them. How to solve this issue?

You have to end the request. Add this at the end of your script:

req.end()

---

When using http.request() , you have to at some point call request.end() .

req = http.request options, (res) ->
    # ...

req.on 'error', # ...

req.end() # <---

Until then, the request is left open to allow for writing a body. And, the error is because the server will eventually consider the connection to have timed out and will close it.

Alternatively, you can also use http.get() with GET requests, which will call .end() automatically since GET requests aren't normally expected to have a body.

in my case it was the 'Content-Length' header - I took it out and it's fine now...

code:

function sendRequest(data)
{
    var options = {
              hostname: host,
              path: reqPath,
              port: port,
              method: method,
              headers: {
                      'Content-Length': '100'
              }
    var req = http.request(options, callback);
    req.end();
    };

after removing the line: 'Content-Length': '100' it sorted out.
