how to get a token to generate a section from login with oauth and angular
4, most of the projects I saw are angled 2 and do not have interceptors and
need multiple files I just need to get a token from my API
I am currently using the code as follows:
public login (user): observable <any> {
let body = JSON.stringify (user);
return this.http.get (this.Jurl, body, {headers: contentHeaders})
// ... and calling .json () on the response to
return data
.map ((res: Response) => res.json ())
//...errors if any
.catch ((error: any) => Observable.throw (error.text
()));
}
// this is in login.service.ts
//this is my user.service.ts
private url: string = 'auth/login';
private _loggedIn: BehaviorSubject<boolean> = new BehaviorSubject(false);
public loggedIn: Observable<boolean> = this._loggedIn.asObservable();
constructor(private http: Http) { }
autentica(usuario: Usuario) {
return this.http
.post(this.url, JSON.stringify(usuario))
.map((res) => {
var token = res.headers.get('x-access-token');
if (token) {
this._loggedIn.next(true);
localStorage.setItem('token', token);
}
});
}
logout() {
localStorage.removeItem('token');
}
isLoggedIn() {
let token = localStorage.getItem('token');
if(token){ //essa atribuição é feita para atualizar a variavel e o
resto do sistema ser notificado
this._loggedIn.next(true);
} else {
this._loggedIn.next(false);
}
return this._loggedIn.getValue();
}
}
// this is my login.component.ts
private router: Router,
private authenticationService: AuthenticationService) {}
ngOnInit () {}
onLogin () {
this.loading = true;
this.authenticationService.login (this.model.user,
this.model.password)
.subscribe (result => {
if (result === true) {
this.router.navigate (['/ dashboard']);
} Else {
this.loading = false;
}
});
}
in the project currently I'm getting an "Access-Control-Allow-Origin" error
does anyone know how to solve this error in my code or do you have a
suggestion for better code organization so I do not have any more errors in
this structure?
