var headers = new Headers();
    headers.append('Content-Type', 'application/x-www-form-urlencoded');
    //let options = new RequestOptions({ headers: headers });

    let postParams = {
        type: 'insertbranch',

        }, error => {
            console.log(error);// Error getting the data

You don’t need custom headers here. Simply create the body as a URLSearchParams and Angular will handle the rest.

Import this:
import { Headers } from ‘@angular/http’;
