NGA Login

NGrid Gas website login. A module to login to the NGrid Gas website using curl. The curl request will write the authenticated cookie to disk and return the path to the cookie file on disk. The cookie file can then be used in subsequent curl requests using the --cookie or -b option.

Installation

npm install -S ngrid-gas-login

Usage

Call with an object that has username and password fields set. If the login is successful the second parameter of the callback will be the path to the authenticated cookie file on disk that can be used in subsequent requests

var ngaLogin = require('ngrid-gas-login')
// currentLogin is a customer login for the https://www1.nationalgridus.com website
var currentLogin = {
  username: '[email protected]',
  password: 'barPassword'
}
ngaLogin(currentLogin, function (err, cookiePath) {
  if (err) {
    console.dir('error logging into ngrid gas website', err)
  }
  console.dir('logged into ngrid gas website correctly, cookie file stored on disk at path', cookiePath)
})

Use the cookie file on disk in another request

var ngaLogin = require('ngrid-gas-login')
// currentLogin is a customer login for the https://www1.nationalgridus.com website
var currentLogin = {
  username: '[email protected]',
  password: 'barPassword'
}
ngaLogin(currentLogin, function (err, cookiePath) {
  var args = [
    '--cookie',
    cookiePath,
    '--insecure',
    url
  ]
  var cmd = 'curl'
  var curl = spawn(cmd, args)
    curl.stdout.setEncoding('utf8')
  var html = ''
  var stdErr = ''
  curl.stdout.on('data', function (data) {
    html += data
  })
  curl.stderr.on('data', function (data) {
    stdErr += data
  })
  curl.on('exit', function(code) {
    // do something useful with the output here

    // code is 0 on success, otherwise a code is a curl error code
    console.dir('curl exit code', code)
  })
})
