我正在将一个项目从angular2 RC4迁移到RC6,我有一个需要的自定义Form Validator Http.在迁移之前我使用了ReflectiveInjectorwith HTTP_PROVIDERS,但是使用了RC6,这已经不再可能了,因为HTTP_PROVIDERS已经弃用了,分别不再存在了.这是Validator中的静态方法:

    static checkVat(control: FormControl) {
    let checkVatUrl = "http://localhost:8080/checkvat";


    let injector = ReflectiveInjector.resolveAndCreate([HTTP_PROVIDERS]);
    let http = injector.get(Http);
    let authHttp = new AuthHttp(new AuthConfig(), http);

    if (control.value === "") {
        return new Observable((obs: any) => {
            obs.next(null);
            obs.complete();
        });
    } else {
        return authHttp.get(checkVatUrl + "/" + control.value)
            .map((data: Response) => {
                if (data.json().valid) {
                    return null;
                } else {
                    let reason = "isNotValidVat";
                    return {[reason]: true};
                }
            })
            .catch(function (e) …
