Class Description
Polyfill for Headers, as specified in the Fetch Spec.
The only known difference between this Headers implementation and the spec is the lack of an entries method.
Example (live demo)
import {Headers} from '@angular/http';
var firstHeaders = new Headers();
firstHeaders.append('Content-Type', 'image/jpeg');
console.log(firstHeaders.get('Content-Type')) //'image/jpeg'
// Create headers from Plain Old JavaScript Object
var secondHeaders = new Headers({
'X-My-Custom-Header': 'Angular'
});
console.log(secondHeaders.get('X-My-Custom-Header')); //'Angular'
var thirdHeaders = new Headers(secondHeaders);
console.log(thirdHeaders.get('X-My-Custom-Header')); //'Angular'
