Trying to make request to Google.com using code from npm require website:
var request = require('request');
request('http://www.google.com', function (error, response, body) {
console.log('error:', error); // Print the error if one occurred
console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
console.log('body:', body); // Print the HTML for the Google homepage.
}); , but receiving this error:
error: { Error: getaddrinfo ENOTFOUND www.google.com www.google.com:80
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:56:26)
errno: 'ENOTFOUND',
code: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'www.google.com',
host: 'www.google.com',
port: 80 }
statusCode: undefined
body: undefined.
I've installed request. How can I fix this?

To install the package use these commands:
npm install node-fetch#2.6.1
npm install --save-dev #types/node-fetch#2.x
I am trying to get a Json file using the following code:
import fetch from "node-fetch";
async function getjson(){
const response = await fetch('https://www.carrefour.es/electronica/television/ofertas-en-televisores-y-accesorios/cat4167531/c', {method: 'GET',
headers:{
Accept: 'application/json'
}
}).catch(e => {console.error('request failed:' , e)});
const result = ( response) ? await response.json(): null;
console.log('start');
console.log(result);
}
getjson();
but instead of returning the expected json file, it returns the following error
reason: Parse Error: Invalid header value char

}
When I use Postman, it returns the expected json file, what was I doing wrong?
Can anyone shed some light on this question please?
I have a github action that looks something like this:
const http = require('http');
const core = require('#actions/core');
const options = {
hostname: 'mydomain.com',
port: 80,
path: '/webhook',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
}
};
const postData = {
foo: 'bar'
}
try {
const strPostData = querystring.stringify(postData);
options.headers['Content-Length'] = Buffer.byteLength(strPostData);
const req = http.request(options)
req.write(strPostData)
req.end()
} catch (error) {
core.info(error.message);
}
if mydomain.com/webhook is offline, my job fails on this action, logging:
events.js:187
throw er; // Unhandled 'error' event
^
Error: connect ECONNREFUSED xxx.xxx.xxx.xxx:80

***
Why does it fail, why doesn't the try catch catch this?
I don't want the entire job to fail if this action fails, so how do I trap this failure and hide it from the GitHub runner?
You will need to listen to the 'error' event to catch this
const strPostData = querystring.stringify(postData);
options.headers['Content-Length'] = Buffer.byteLength(strPostData);
const req = http.request(options)
req.on('error', (err) => {/*Error Caught*/})
req.write(strPostData)
req.end()

Update:
const options = {
user: config.get('MYSQL_USER'),
password: config.get('MYSQL_PASSWORD'),
database:config.get('DATABASE'),
host: config.get('HOST'),
port: 3306
}
const connection = mysql.createConnection(options);
connection.connect( function (err) {
if (err) {
console.log("!!! Cannot connect !!! Error:"); throw err;
} else {
console.log("Connection established.");
}
});
use below
const options = { connectionLimit :10, user:config.get('MYSQL_USER'), password: config.get('MYSQL_PASSWORD'), database:config.get('DATABASE'), host: config.get('HOST'), port: 3306 }
const connection_pool = mysql.createPool(options);
connection_pool.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
if (error) throw error;
console.log('The solution is: ', results[0].solution);
});
provide connectionLimit according to you use this is pool size of connection
Below is the code Snippet :
var mongoose = require('mongoose');
//mongodb://localhost/db
mongoose.connect('mongodb://username:pwd#ds117859.mlab.com:17859/db');
var db = mongoose.connection;
Now when I connect to localhost server, it works fine and I am able to perform operations on local Mongo DB
But when I connect to my db on MLAB, I get the following error:
$ node app.js
Server started on port 3000
