    Headers,
    RequestOptions
} from '@angular/http';
import 'rxjs/add/operator/map';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    productsList = '';
    show: boolean;
    hide: boolean;
    listBtn: boolean;
    gridBtn: boolean;
    values = '';

    onKey(event: any) { //without type info
        this.values += event.target.value;
        console.log("value " + this.values);
    }
    listView() {
        this.gridBtn = true;
        this.show = true;
        this.hide = false;
        this.listBtn = false;
    }
    gridView() {
        this.listBtn = true;
        this.gridBtn = false;
        this.show = false;
        this.hide = true;

    }
    constructor(private http: Http) {
        this.show = false;
        this.hide = true;
        this.show = false;
        this.listBtn = true;
        this.gridBtn = false;
        this.getData();
    }
    createAuthorizationHeader(headers: Headers) {
        headers.append('Authorization', 'Basic ' +
            btoa('ck_543700d9f8c08268d75d3efefb302df4fad70a8f:cs_f1514261bbe154d662eb5053880d40518367c901'));
        headers.append("Content-Type", "application/x-www-form-urlencoded");
    }
    getData() {
        console.log('hellooo');
        let headers = new Headers();
        this.createAuthorizationHeader(headers);
        return this.http.get(' https://www.colourssoftware.com/wordpress/wp-json/wc/v2/products', {
            headers: headers
        })
            .subscribe(res => {
                const products = res.json();
                console.log(products);
                this.productsList = products;
                console.log(this.productsList);
            })


    }

}
