i'm trying to call the url for sending SMS, getting this kind of error
{ [Error: getaddrinfo ENOTFOUND alerts.sinfini.com]
code: 'ENOTFOUND',
errno: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'alerts.sinfini.com' }
my node js code is
var request = require('request');
request(url, function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // Show the HTML for the Google homepage.
}else{
console.log(error);
}
});
In the above code where is the URL defined? Have you checked the URL working fine via rest clients! ENoT thrown for either URL or DNS is not get resolved

i have created api in node.js which consume set of api hosted at http://dev.abc.co.in:20081
not every time but randomly sometimes it throws the error
Error: getaddrinfo ENOTFOUND dev.abc.co.in
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:60:26) {
errno: 'ENOTFOUND',
code: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'dev.abc.co.in'
}
to call those api i have used request node module because i started getting this error i switched to fetch-node npm module and finally replace the code with internal node module http but getting same error
here is the code i have written using http.request
try{
const options = {
hostname: "dev.abc.co.in",
port : 20081,
path: "/api/entity/workorder",
method: Config.method
};
if(Config.headers){
options.headers = Config.headers
}
const req = http.request(options, (res) => {
let data = '';
res.on('data', (chunk) => {
data += chunk;
});
res.on('end', () => {
callback(res, data);
});
req.socket.destroy();
}).on("error", (err) => {
console.log("===Error: ", err);
callback(null, err);
});
if(Config.method!="GET" && Config.body){
Config.headers["Content-Length"] = Config.body.length;
req.write(Config.body);
}
req.end();
}catch(e){
console.log("Exception=====",e);
}
as shown in error message issue related to DNS so i try to resolve this DNS using
node -pe 'require("dns").lookup("dev-vsg.dovertech.co.in",function(){console.dir(arguments)})
but still not resolved.
1) Omit 'http://' from the beginning of your demain and all slashes from the end or any path after the actual domain.
2) Try to resolve your hostname:
const dns = require('dns');
dns.resolve("testdomain.com", 'ANY', (err, records) => {
if (err) {
console.log("Error: ", err);
} else {
console.log(records);
}
});
If dns records has been returned, then you will know it's a node js problem and after that we can investigate further. If not, then it's a domain configuration issue.
I'm trying to use NodeJS get requets using the 'request' module, so here is my code:
var request = require('request');
request({
'url':'http://whatismyip.host/',
'method': "GET",
'proxy': 'http://181.112.225.78:35482'
},function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
else{
console.log(error);
}
})
When I remove the "'proxy': 'http://181.112.225.78:35482'" line, it works perfectly, but when I let it, I have this error:
{ Error: connect ECONNREFUSED 181.112.225.78:35482
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1117:14)
errno: 'ECONNREFUSED',
code: 'ECONNREFUSED',
syscall: 'connect',
address: '181.112.225.78',
port: 35482 }
I already tried to change the proxy, and I got the same error, so I have no idea where is it coming from...
Thanks you !
Code:
var rp = require('request-promise');
var options = {
method: 'POST',
uri: 'http://c663fe13.ngrok.io/ap/lighton',
body: {"color": 'white'},
json: true // Automatically stringifies the body to JSON
};
rp(options)
.then(function (parsedBody) {
// POST succeeded...+
console.log("parsedBody", parsedBody);
})
.catch(function (err) {
// POST failed...
console.log("err", err);
});
but this gives me the following error:
{ RequestError: Error: getaddrinfo EAI_AGAIN c663fe13.ngrok.io:80

I trie to call that API with postman and it's working fine.
If you are using a free account you will not be able to hit any 3rd party services from Firebase cloud functions. It would be better if you write down your own webhook code and using fulfillment integrate that webhook with your Dialogflow agent if you are going to use the free account.
UPDATE
Check out the code snippets I have shared here. You can use that to integrate ExpressJS and then add your POST code and host it locally. Expose the local server using ngrok and then put that URL in fulfillment.
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.
Here is my code:
utilitesRouter.route('/url')
.post(function(request, response) {
console.log(request.body.uri);
var urlOpts = { host: request.body.uri, path: '/', port: '80', method: 'GET' };
var re = /(<\s*title[^>]*>(.+?)<\s*\/\s*title)>/gi;
http.get(urlOpts, function (response) {
response.on('data', function (chunk) {
var str=chunk.toString();
console.log(str);
var match = re.exec(str);
if (match && match[2]) {
console.log(match[2]);
}
});
});
response.json({ url: request.body.uri });
});
If I use POST request with this JSON {"uri":"google.ru" } I get:
302 Moved
google.ru
<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>301 Moved</TITLE></HEAD><BODY>
<H1>301 Moved</H1>
The document has moved
here.
</BODY></HTML>
If I use POST requiet with JSON {"uri":"http://google.ru" } I get the error message:
events.js:85
throw er; // Unhandled 'error' event
^
Error: getaddrinfo ENOTFOUND http://google.ru
at errnoException (dns.js:44:10)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:94:26)
I can open http://google.ru in my browser.
How can I get the HTML using node.js ?
You may want to request to do that. It just pretty easy.
var request = require("request");
router.get('/proxy', function(req, res, next){
request.get( req.body.uri, function(error, response, body){
if( error )
return next(error);
res.send(body);
});
});
request also support streaming and other cool features too.
You get the error because in your urlOpts the attribute host has to be a domain name, like google.ru or www.google.ru. As you are putting a URL into it, it can't be resolved to an IP via DNS, that's why you get the error at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:94:26).
If you want to use http.get() like the way you do, you would always have to extract the domain part out of your passed uri, i.e. getting google.ru out of http://google.ru to use it as host.
