Node.js Question

nodejs request ECONNREFUSED

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:

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);
