Has anyone connected successfully to the REST API using angular? I'm more of a C# dev, but do a little bit here and there with angular. Thought I'd take some of my old code and recreate them with angular. So far it's not going well 
I'm trying to start out with just getting a session, but seem to be getting hung up on the headers. I've confirmed the headers are being set, but the error I'm getting in the Console Tools is something I've never seen.
archer.services.ts file:
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map';
@Injectable()
export class ArcherService {
constructor(private http: HttpClient) { }
getArcherSessionToken() {
console.log('Attempting to get session token');
const creds = {'InstanceName': 'ArcherInstance', 'Username': 'SysAdmin', 'UserDomain': '', 'Password': 'Password123!'};
let superheader = new HttpHeaders().set('Content-Type', 'application/json');
superheader = superheader.set('Accept', 'application/json,text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8');
this.http.post('http://localhost/RSAarcher/api/core/security/login',
JSON.stringify(creds),
{ headers: superheader}).subscribe(
(val) => {
console.log('Post success', val);
},
response => {
console.log('Post call in error', response);
},
() => {
console.log('The Post observable is now completed.');
});
}
}
Anyone have any ideas?
