node.js - ECONNREFUSED in Node http module -

when remote site off-line getting error in consuming client (node.js v0.12.0 http module):

 uncaught exception: connect econnrefused  error: connect econnrefused      @ exports._errnoexception (util.js:746:11)      @ tcpconnectwrap.afterconnect [as oncomplete] (net.js:983:19) 

the code i'm using looks this:

var req = http.request(options, function (res) {     res.on('socket', function (socket) {         socket.setkeepalive(true, 0);         socket.setnodelay(true);     });      res.on('end', function () {         log.debug('success');     }).on('error', function () {         log.error('response parsing failed');     }); }).on('error', function () {     log.error('http request failed'); });  req.write(packet); req.end(); 

the "error" event never fired when econnrefused occurs, i've tried using "clienterror" event not fired either.

how can capture error?

note: post bit old

the next example http.createclient think same

unfortunately, @ moment there's no way catch these exceptions directly, since stuff happens asynchronously in background.

all can catch uncaughtexception's on own:

process.on('uncaughtexception', function (err) {     console.log(err); });  

maybe helps you!
