I know there a already lot of same solved issues here,
but unfortunately none of them helped me :-(.
Here my problem:
I try to connect from my localhost to my REST service on a server. It works fine with a FF REST plugin, but my application results in following errors:
- OPTIONS http://.../my_REST_Service/ 401 (Unauthorized)
- XMLHttpRequest cannot load http://.../my_REST_Service/.
Response for preflight has invalid HTTP status code 401
How I try to get the data I want:
@Injectable()
export class ModelsComponent implements OnInit {
private restRoot = 'http://.../my_REST_Service';
private data;
constructor(private http: Http) { }
ngOnInit() {
this.getModels().subscribe(res => {
this.data = res;
console.log(this.data);
});
}
authHeaders() {
let username: string = 'xxxx';
let password: string = 'xxxx';
let token: string = btoa(username + ":" + password);
let headers: Headers = new Headers();
headers.append('Access-Control-Expose-Headers', 'Authorization');
headers.append('Authorization', 'Basic ' + token);
headers.append("Access-Control-Allow-Origin", "http://localhost:4200/");
headers.append("Access-Control-Allow-Methods", "*");
headers.append("Access-Control-Allow-Headers", "Accept,Accept-Charset,Accept-Encoding,Accept-Language,Authorization,Connection,Content-Type,Cookie,DNT,Host,Keep-Alive,Origin,Referer,User-Agent,X-CSRF-Token,X-Requested-With");
headers.append("Access-Control-Allow-Credentials", "true");
return headers;
}
getModels(): Observable<any> {
return this.http.get(this.restRoot, {
headers: this.authHeaders(),
withCredentials: true <- from a similar issue
}).map(res => res.json());
}
}
My Server is configured like this:
Header set Access-Control-Allow-Origin "http://localhost:4200"
Header set Access-Control-Allow-Headers "Accept,Accept-Charset,Accept-Encoding,Accept-Language,Authorization,Connection,Content-Type,Cookie,DNT,Host,Keep-Alive,Origin,Referer,User-Agent,X-CSRF-Token,X-Requested-With"
Header set Access-Control-Allow-Methods "*"
Header set Access-Control-Allow-Credentials "true"
Header set Access-Control-Expose-Headers "Authorization" <- from a similar issue
I know there are other same/ similar solved issues. But I still do not know what to do or how to do it. I really appreciate it if someone can help me with my code!!
