patch

I just hard coded value:

changeSupportedLanguage() {
        this.userService.patchMyProfile(['fr']);
    }

  patchMyProfile(languages: string[]) {
        return this.apiService.patch(`${config.myProfile}`, { languages: languages }).map((res: any) => res.json());
    }

patch(url, params): Observable<any> {
        return new Observable(observer => {
            let header = new Headers();
            this.createHeader(header)
                .then(() => {
                    let options = new RequestOptions({ headers: header });
                    this.http.patch(url, params, options)
                        .subscribe(response => {
                            observer.next(response);
                            observer.complete();
                        }, (e) => {
                            observer.error(e);
                        });
                })
        })
    }
