私はソーシャルネットワーク経由でログインするサービスを作成しました。 私の問題は使用中にエラーが発生しています。 は私の主なコンポーネントは次のとおりです。サービスを利用できません
import {Component, ViewEncapsulation} from '@angular/core';
import {UserData} from '../../theme/services/userData';
@Component({
selector: 'login',
encapsulation: ViewEncapsulation.None,
styles: [require('./login.scss')],
template: require('./login.html'),
})
export class Login {
constructor(public _userData: UserData) {
}
login(form: string) {
this._userData.login(form);
}
サービス:
import {Injectable} from '@angular/core';
import {AngularFire, AuthProviders} from 'angularfire2';
@Injectable()
export class UserData {
user = {};
isAuth = false;
constructor(public af: AngularFire) {
debugger;
this.af.auth.subscribe(user => this._changeState(user));
}
エラーは以下のとおりです。
