Node-Fetch API GET with Headers

Question

https://www.npmjs.com/package/node-fetch Node v6.4.0 npm v3.10.3

I want to send a GET Request with custom headers in this API call.

const fetch = require('node-fetch')
var server = 'https://example.net/information_submitted/'

var loginInformation = {
    username: "[email protected]",
    password: "examplePassword",
    ApiKey: "0000-0000-00-000-0000-0"
}

var headers = {}
headers['This-Api-Header-Custom'] = {
    Username: loginInformation.username,
    Password: loginInformation.password,
    requiredApiKey: loginInformation.ApiKey
}

fetch(server, { method: 'GET', headers: headers})
.then((res) => {
    console.log(res)
    return res.json()
})
.then((json) => {
    console.log(json)
})

The headers are not applying, I am denied access. But within a curl command, it works perfectly.

I think you need to use the Headers constructor, instead of a plain object.

https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch#Headers

myHeaders = new Headers({
  "Content-Type": "text/plain",
  "Content-Length": content.length.toString(),
  "X-Custom-Header": "ProcessThisImmediately",
});
