i have some ECONNREFUSED with 'request' module, but some time my request passe without error O_o ...
So i make my request recurcive but this not solve the problème ...
let request = require("request");
let currency = 'btceur';
let data = [];
let url = "https://api.cryptowat.ch/markets/kraken/" + currency + "/price";
let nbTry = 0;
let nbMaxTry = 5;
let callbackRequest = (error, response, body) => {
if (error || response.statusCode != 200) {
console.log('error', 'error, retry ' + (nbTry + 1) + "/" + nbMaxTry);
console.log(error);
if (nbTry <= nbMaxTry) {
nbTry++;
request(url, callbackRequest);
} else {
console.log(data);
}
} else {
let bodyjson = JSON.parse(body);
bodyjson.result.currency = currency;
data.push(bodyjson.result);
console.log(data);
}
};
request(url, callbackRequest);
console output:
error error, retry 1/5

api.cryptowat.ch resolves to two IP-numbers, 23.239.28.55 and 69.164.196.116. The latter is giving issues (for me as well).
You could try using the former for each request as a temporary workaround:
let url = "https://23.239.28.55/markets/kraken/" + currency + "/price";
It doesn't seem to need a Host header, although it would probably be better if you passed one anyway:
request({ url, headers : { Host : 'api.cryptowat.ch' } }, callbackRequest);

I am using oneSignal for push notifications node.js. I am using the create notification api to send notification to the users, but i dont know why it works some times and sometimes gives timeout error
sendNotificationToUser(data) {
try {
var notificationData = {}
notificationData.app_id = oneSignalAppId
notificationData.headings = {
en: "Heading"
}
notificationData.contents = {
en: data.message
}
notificationData.include_player_ids = [data.deviceId]
var headers = {
"Content-Type": "application/json; charset=utf-8"
}
var options = {
host: "onesignal.com",
port: 443,
path: "/api/v1/notifications",
method: "POST",
headers: headers
}
var https = require("https")
var req = https.request(options, function (res) {
res.on("data", function (data1) {
console.log("Response:")
console.log(JSON.parse(data1))
})
})
req.on("error", function (e) {
console.log("ERROR:")
console.log(e)
})
req.write(JSON.stringify(notificationData))
req.end()
} catch (err) {
console.log("err in notification", err)
}
}
this api works 50% of times and 50% of times it responds with time out error, even all the inputs are correct
ERROR:
{
Error: connect ETIMEDOUT 104.18.225.52:443
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1107:14)
errno: 'ETIMEDOUT',
code: 'ETIMEDOUT',
syscall: 'connect',
address: '104.18.225.52',
port: 443
}
one simple solution is to directly hit the working ip, you can do this by including
host: 'onesignal.con' in headers and
host: '104.18.226.52' in options
this resolved my issue
to know more about how you can specify ip with host in https request
go here HTTPS request, specifying hostname and specific IP address
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 !
I am getting this weird error:
Making request to bitbucket api at path: /2.0/repositories/interos/eco-system-globe/commit/116c82c81b8d3e1b8c2fd3f352510fd09e66a02e
***Request stream error***: Error: write EPROTO 139717438125888:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:332:
at WriteWrap.onWriteComplete [as oncomplete] (internal/stream_base_commons.js:83:16) {
errno: 'EPROTO',
code: 'EPROTO',

}
the code I have is simply:
const pth = `/2.0/repositories/${fullRepoName}/commit/${sha}`;
console.log('Making request to bitbucket api at path:',pth);
const newReq = https.get({ // formerly get
protocol: 'https:',
port: 80,
hostname: 'api.bitbucket.org',
path: pth,
headers: {
'Authorization': `Basic ${bitbucketBase64}`,
'Auth': `Basic ${bitbucketBase64}`
}
}, r => {
const v = {
data: ''
};
r.on('data', d => {
v.data += String(d || '');
});
r.once('end', () => {
console.log('response ended:', r.statusCode);
cb(null, v);
});
});
newReq.once('error', e => {
console.error('***Request stream error***:', e);
});
// newReq.write(stringified);
newReq.end();
anyone have an idea what that's about? I am on Node.js version 12.2.0
I had port: 80 but it should be port: 443 ... for SSL that's the default, so you can just omit the port argument.
I'm trying to use the request-module to scrape websites and get the response-HTML. To prevent getting blocked by the target sites I need to use some proxies. But for some reason I can not accomplish to use request with a proxy.
I've also tried many different proxies and none of them will do the job.
My code:
const request = require('request');
const cheerio = require('cheerio');
var servers = [
'http://173.249.48.240:8080',
'http://85.214.250.48:3128'
]
var options = {
'url': 'http://www.google.de',
'proxy': servers[1]
};
request(options, (err,res,body) => {
console.log(res);
console.log(body);
console.log(err);
try {
var $ = cheerio.load(body);
console.log($('#ipv4').html());
} catch(err) {
//do nothing
}
})
I've tried many different proxies and have also used nightmare before but everytime I try to connect with a Proxy I get the following exception:
{ Error: connect ECONNREFUSED 85.214.250.48:3128
