template: `
<h3>File Upload</h3>

<div>
     Select file:
    <input type="file" (change)="changeListener($event)">
</div>

`
})
export class FileUploadCmp {

public file: File;
public url: string;
headers: Headers;


constructor(public http: Http) {
    console.log('file upload Initialized');
    //set the header as multipart        
    this.headers = new Headers();
    this.headers.set('Content-Type', 'multipart/form-data');
    this.url = 'http://localhost:8080/test';
}

//onChange file listener
changeListener($event): void …
