I run node myserver.js that contains the code bellow, and after 40-50sec I get the error(bellow the code). Why do I get an error when nothing is happening?
var options = {
host: 'google.com',
port: '80',
path: '/',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': 'post_data.length'
}
};
var subscribeRequest = require('http').request(options, function(res) {
console.log('send request');
}).on('error', function(err){console.log(err.stack)});
after 40-50sec I get this error:
Error: connect ETIMEDOUT
at errnoException (net.js:904:11)
at Object.afterConnect [as oncomplete] (net.js:895:19)
I see at least two things wrong here:
You're not ending your request. When you use http.request() you have to call .end() on the request object returned when you are done sending any data so that the server knows there is no more data coming. http.get() automatically calls .end() for you because there are no bodies with GET requests.
'Content-Length': 'post_data.length' should be 'Content-Length': post_data.length
You have to call subscribeRequest.end() after declaring your request! If you don't do it, your request will never be sent

I am trying connect third part server with basic auth and pfx tls certificate using node express platform. I am not sure; Where do I need to set basic auth, cert file and header params?
For get operation call from remote server, I have tried to use, https client and tls tool.
Request requires ;
header = basic auth,schemaVersion, id, applicationName
In addition to sending the basic auth credentials, send the following in the HTTP Header: Content-Type: application/json
Accept: application/json
and also request require one additional parameter i.e. categories
onst https = require('https');
const options = {
hostname: 'https://yadda/cards/getAssets',
headers: {
Authorization: 'Basic ' + new Buffer(username + ':' + passw).toString('base64'),
schemaVersion: '2.0.0',
id: '0000000',
applicationName: 'yadda',
Accept: 'application/json',
'Content-Type': 'application/json',
},
pfx: fs.readFileSync('/somefile.cert.pfx'),
passphrase: 'passphrase',
categories: 'food',
};
https
.get(options, (response: any) => {
response.on('data', (d: any) => {
console.log(`BODY: `, d);
});
})
.on('error', (e: any) => {
console.error('Error: ', e);
});
// With Tls tool, I tried as;
var fs = require('fs');
var socket = tls.connect(options, () => {
console.log('client connected');
process.stdin.pipe(socket);
process.stdin.resume();
});
I would like to get connected with remote server and receive data in response; instead I am getting following error;
ERROR] Error: { Error: getaddrinfo ENOTFOUND https://yadd/cards/getAssets:443
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:67:26)
errno: 'ENOTFOUND',
code: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'https://yadda/cards/getAssets',
A hostname (like www.example.com) is expected here, not a URL. The string you gave will be used as hostname and a DNS lookup will fail:
ERROR] Error: { Error: getaddrinfo ENOTFOUND https://yadd/cards/getAssets:443
I am trying to get couchbase document revision identifier via sync gatetway API GET /{db}/{doc} within Node server:
function _getRev(docIdUrl, gateway, callback) {
let options = {
host: gateway.host,
path: gateway.path + docIdUrl,
port: gateway.port,
method: 'GET',
headers: {
'Content-Type': 'application/json'
}
};
// Node HTTP requests
let syncGatewayRequest = http.request(options, (response) => {
// ...unrelevant codes
});
syncGatewayRequest.on('error', (error) => {
logger.error('syncGateway connection error for ' + docIdUrl);
callback(error, null); // here is the error happening!!!!!
});
syncGatewayRequest.write(JSON.stringify({}));
syncGatewayRequest.end();
}
Then I got error:

There is a context that the above function are executed asynchronously by a significant number of services, say 10,000+
I noticed the post here Nodejs connect EMFILE - How to reuse connections?
But I tried to unlimit the default connections by doing:
var http = require('http')
http.globalAgent.maxSockets = Infinity
But does not seem to work, error still ...
Anyone can let me know what's wrong here?
At one point I just want to make a POST request to my rails server running on localhost:3000
If a use like postman on even cUrl I can ping my API
But kow, with my node app I want to do this :
var req_body = {
'my_id': id,
'dataTable': data }
var options = {
method: 'POST',
url: config.get('api_url') + 'end_tracking',
json: true,
body: req_body
}
// config.get('api_url') return http://localhost:3000/
request(options, function (error, response, body) {
console.log(error)
... }
this is what I get :
{ Error: connect ECONNREFUSED 127.0.0.1:3000
at Object.exports._errnoException (util.js:896:11)
at exports._exceptionWithHostPort (util.js:919:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1073:14)
code: 'ECONNREFUSED',
errno: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: 3000 }
and as I said, if I do this request directly with postman, everything works !
I finally did it !
For a unknown reason, accessing localhost:3000, launched with rails s didn't work at all on my node server
but I worked when I started the rails server with rails s -b 0.0.0.0 !
how i did this , just use the same structure and i hope it works for you
request({
url: url, //URL to hit
method: 'post',
headers: headers,
timeout: 10000,
body: JSON.stringify(body)
}, function (error, result, body) {
if (error) {
console.log(error);
} else if (result.statusCode == 500) {
console.log('not found');
} else {
console.log('success')
}
});
hope it works.
I am trying to run the following node code,
function getQuestions() {
var options = {
host: 'mysite.com',
path: '/services/v2/question.json',
headers: {
"Content-Type": "application/json",
"accept": "application/json; charset=UTF-8",
'Authorization': auth
}
};
http.request(options, function(response) {
console.log("Everything worked!");
}).on('error', function(e) {
console.log('problem with request: ' + e.stack);
});
}
But it always errors saying...
problem with request: Error: connect ECONNREFUSED
at errnoException (net.js:905:11)
at Object.afterConnect [as oncomplete] (net.js:896:19)
When I put the same info into Postman it works fine. Is there a way to debug this?
Update
Tried this...
var options = {
host: "google.com"
};
Same result so something must be wrong in my code. Any ideas?
It did end up being a proxy issue this...
var options = {
host: "proxy",
port: 80,
path: 'http://google.com'
};
Notice the proxy in host. I will mark as duplicate of this post
Below is the error getting while calling http get request
events.js:66
throw arguments[1]; // Unhandled 'error' event
^
Error: getaddrinfo ENOENT
at errnoException (dns.js:31:11)
at Object.onanswer [as oncomplete] (dns.js:123:16)
PFB my code throwing the error
var options = {
host: 'http://xyz.com',
port: 80,
path : 'test?query=' + escape(req.params.searchTerm) + '&offset=0&hits=500',
method: 'GET',
headers: {
Cookie : "session=" + session
}
};
console.log("Start");
var x = http.request(options,function(subRes){
console.log("Connected");
subRes.on('data',function(data){
console.log("===================data===" +util.inspect(data));
});
});
x.end();
Any ideas, why this error ?
ENOENT is an error that indications name resolution did not return any results. You specify the hostname as http://xyz.com, but colons are not allowed in hostnames. You want:
var options = {
host: 'xyz.com',
You specify the host as http://xyz.com, which should just be xyz.com.
This value is used to resolve the IP address of the host you're trying to connect to using DNS.
