Hello guys
I am making a simple get request on my angular 4 application. I am getting
this error: "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:4200' is therefore not allowed access.
The response had HTTP status code 401."
The get request in my service class looks like this:
return
this.http.get('http://localhost:7990/bitbucket/rest/project/1.0/project/second',
{
"headers" : new HttpHeaders().append('Authorization', 'Basic
YWRtaW46YWRtaW4=')
}).subscribe(data => {
console.log(data);
});
The resource that is being called looks like this:
@GET
@Produces({ MediaType.APPLICATION_JSON })
@Path("/second")
@CrossOrigin
public Response getFirstProjects() {
return Response.ok().header("Access-Control-Allow-Origin", "*")
.header("Access-Control-Allow-Headers", "Authorization").build();
}
Can someone explain what is happening and how I can fix that? I am pretty
new to angular and rest in general. Can someone please give an
explanation/correction or a full example.
Extra info: Service class import:
import { Injectable } from '@angular/core';
import { Http } from '@angular/http';
import { HttpHeaders, HttpClient, HttpHandler } from '@angular/common/http';
import 'rxjs/add/operator/map';
@Injectable()
export class ProjectService {
constructor(public http:HttpClient, public httpHandler:HttpHandler) {
console.log('Data service connected...');
}
