This error in Mozila :
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.uber.com/v1/products?latitude=12.9716&longtitude=77.5946. (Reason: missing token 'access-control-allow-headers' in CORS header 'Access-Control-Allow-Headers' from CORS preflight channel).

This error is in Chrom:
XMLHttpRequest cannot load https://api.uber.com/v1/products?latitude=12.9716&longtitude=77.5946. Request header field Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers in preflight response.

i am not sure it origin mismatch or token not assigned in the header, i am not using oauth i just want to authenticate with server token provided by the uber api server.

this is my code:

client.service.ts
getEstimatesForUserLocation (lat:number,lon:number) {

let endpoint = 'https://api.uber.com/v1/products';
let url  = `${endpoint}?latitude=${lat}&longtitude=${lon}`;
let headers = new Headers();

headers.append('Authorization', 'SERVER_TOKEN');//assigning my server token to header
headers.set('Access-Control-Allow-Origin', '*');
headers.get('Access-Control-Allow-Origin');
headers.append('Access-Control-Allow-Headers','x-requested-with, Content-Type, origin, authorization, accept, client-security-token');
headers.get('Access-Control-Allow-Headers');

return this.http.get(url, {headers})
  .map(res => res.json());

}
client.component.ts

getEstimatesForUserLocation() {
this._countryService.getEstimatesForUserLocation(this.lat, this.long )
.subscribe(
data=> this.row = data,
error =>this.error = "location" + this.lat + this.long + "invalid."
);

}

can any one please tell me server token which i am assigning here is correct?
note: i am using @angular/http package
