Error: getaddrinfo ENOTFOUND in nodejs for get cal

Question

I am running a web server on node the code for which is given below

var restify = require('restify');

var server = restify.createServer();

var quotes = [
  { author : 'Audrey Hepburn', text : "Nothing is impossible, the word itself says 'I'm possible'!"},
  { author : 'Walt Disney', text : "You may not realize it when it happens, but a kick in the teeth may be the best thing in the world for you"},
  { author : 'Unknown', text : "Even the greatest was once a beginner. Don't be afraid to take that first step."},
  { author : 'Neale Donald Walsch', text : "You are afraid to die, and you're afraid to live. What a way to exist."}
];

server.get('/', function(req, res) {
  res.json(quotes);
});

server.get('/quote/random', function(req, res) {
  var id = Math.floor(Math.random() * quotes.length);
  var q = quotes[id];
  res.json(q);
});

server.get('/quote/:id', function(req, res) {
  if(quotes.length <= req.params.id || req.params.id < 0) {
    res.statusCode = 404;
    return res.send('Error 404: No quote found');
  }

  var q = quotes[req.params.id];
  res.json(q);
});

server.listen(process.env.PORT || 3011);

And then i want to do a get request in the following code

var https = require('http');

/**
 * HOW TO Make an HTTP Call - GET
 */
// options for GET
var optionsget = {
    host : 'http://localhost',
    port : 3010,
    path : '/quote/random', // the rest of the url with parameters if needed
    method : 'GET' // do GET
};

console.info('Options prepared:');
console.info(optionsget);
console.info('Do the GET call');

// do the GET request
var reqGet = https.request(optionsget, function(res) {
    console.log("statusCode: ", res.statusCode);
    // uncomment it for header details
//  console.log("headers: ", res.headers);


    res.on('data', function(d) {
        console.info('GET result:\n');
        process.stdout.write(d);
        console.info('\n\nCall completed');
    });

});

reqGet.end();
reqGet.on('error', function(e) {
    console.error(e);
});

I am just starting with node and i dont even know if this is the right way. I want to test the performance of express and restify.I have done a apache benchmark test for the server code i wrote and found contradicting results that restify is better.So i want to test out some more by making calls to remote services and then later read write to mongodb.The above code is my starting point.I am getting the error

{ [Error: getaddrinfo ENOTFOUND] code: 'ENOTFOUND', errno: 'ENOTFOUND', syscall: 'getaddrinfo' }

Am i atleast heading in the write direction? What is the right way to the kind of tests that i want to? Why did i get the result restify faster than express? Can anyone guide me to the best starting point tutorials for application in node/express/backbone and mongodb?

Answer 1

getaddrinfo ENOTFOUND means client was not able to connect to given address. Please try specifying host without http:

var optionsget = {
    host : 'localhost',
    port : 3010,
    path : '/quote/random', // the rest of the url with parameters if needed
    method : 'GET' // do GET
};

Regarding learning resources, you won't go wrong if you start with http://www.nodebeginner.org/ and then go through some good book to get more in-depth knowledge - I recommend Professional Node.js , but there's many out there.

i have same issue with Amazon server i change my code to this

var connection = mysql.createConnection({
    localAddress     : '35.160.300.66',
    user     : 'root',
    password : 'root',
    database : 'rootdb',
});

check mysql node module https://github.com/mysqljs/mysql

I was running into the same problem and after some trial and error discovered that my hosts file customisation was causing the problem.

My localhost DNS was overwritten and because of that a simple ping was failing:

$ ping http://localhost
# ping: cannot resolve http://localhost: Unknown host

Once I resolved the configuration of /private/etc/hosts file, pinging localhost successfully worked, and was no longer getting the error that you were seeing:

# Fatal error: getaddrinfo ENOTFOUND

I also had same problem and I fixed it by using right proxy. Please double check your proxy settings if you are using proxy network.

Hope this will help you -

Answer 5

When I tried to install a new ionic app, I got the same error as follows, I tried many sources and found the mistake made in User Environment and System Environment unnecessarily included the PROXY value. I removed the ```user variables http://host:port PROXY

system Variables http_proxy http://username:password@host:port ```` and now it is working fine without trouble.

[ERROR] Network connectivity error occurred, are you offline?

        If you are behind a firewall and need to configure proxy settings, see: https://ion.link/cli-proxy-docs

        Error: getaddrinfo ENOTFOUND host host:80

Answer 6

I can't explain why, but changing url parameter from having localhost to 127.0.0.1 on mongodb.MongoClient.connect() method on Windows 10 solved the issue.
