Unable to send data to laravel using ionic 2 - php

Question

I am working on a Hybrid application I want to sent json data to laravel php server using Ionic 2.
I am continuously getting error as
XMLHttpRequest cannot load http://192.168.0.101:8000/SaveUsers.
Response to preflight request doesn't pass access control check: No
'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'http://localhost:8100' is therefore not allowed
access.
Ionic Code:
register-recipient-page.ts
this.registrationService.sendData(this.donarDetails,this.recipientDetails).subscribe(
response => console.log(response), // success
error => console.log(error), // error
() => console.log('completed') // complete
);
Ionic Code:
registration.service.ts
sendData(recipient,donar): Observable<Object> {
let encoded_data = JSON.stringify({recipientDetails:recipient, donarDetails:donar});
let headers = new Headers();
headers.append('Content-Type', 'application/json;charset=utf-8');
headers.append('Access-Control-Allow-Origin', '*');
headers.append('Access-Control-Allow-Methods', 'GET, POST, PUT,DELETE, OPTIONS');
//let headers = new Headers({ 'Content-Type': 'application/json;charset=utf-8' });
let options = new RequestOptions({ headers: headers });
console.log(encoded_data);
return this.http.post( 'http://192.168.0.101:8000/SaveUsers',encoded_data, options).map(
(res: Response) => res.json() || {}
);
}
laravel: web.php
Route::group(['middleware' => 'cors'], function(){
Route::get('/SaveUsers', 'UserController#saveUser');
});
Cors.php
public function handle($request, Closure $next){
return $next($request)
->header('Access-Control-Allow-Origin', '*')
->header('Access-Control-Allow-Methods', 'GET, POST, PUT,DELETE, OPTIONS');
}
I tried to do testing using simple get on the same url without sending any data, it was working fine.
Please help!!!!
