angular - Angular2 http get restfull api request not working -

-

i got angular2 , ran problem don't see how fix. trying data restfull api , worked fine. problem when tried restfull api, test, not me data.

so call api worked: http://jsonplaceholder.typicode.com/posts

works() {     return new promise(resolve => {         this.http.get('http://jsonplaceholder.typicode.com/posts')         .map(res => res.json())         .subscribe(data => {              this.data = data;              console.log(data);              resolve(this.data);         }, error => console.error(error));     });   }

but call api did not: http://gokhankaradas.com/wp-json/posts goes error condition. (object {_body=event error, status=200, statustext="ok", ...})

doesnotwork() {     return new promise(resolve => {         this.http.get('http://gokhankaradas.com/wp-json/posts')         .map(res => res.json())         .subscribe(data => {              this.data = data;              console.log(data);              resolve(this.data);         }, error => console.error(error));     });   }

am missing something?

i might have solved myself.

i created simple result via laravel, product list, , spit out in json format , tested it. failed failing api. 

public function test(product $product){     $products = $product->get();     return response::json($products, 200); }

then added following code routes.php , worked. guess api failing didnt have that. not sure bout seems fix problem ;)

header('access-control-allow-origin:  *'); header('access-control-allow-methods:  post, get, options, put, delete');
