我正在尝试使用 Auth0 进行社交登录，但我不断收到未定义引用的异常。
这是身份验证服务
import { Injectable } from '@angular/core';
import { tokenNotExpired } from 'angular2-jwt';
// Avoid name not found warnings
declare var Auth0Lock: any;
@Injectable()
export class AuthService {
// Configure Auth0
lock = new Auth0Lock('I have set the ID correctly here', 'and the domain as well', {});
constructor() {
// Add callback for lock `authenticated` event
this.lock.on("authenticated", (authResult) => {
localStorage.setItem('id_token', authResult.idToken);
});
}
public login() {
// Call the show method to display the widget.
this.lock.show();
};
public authenticated() {
// Check if there's an unexpired JWT
// This searches for an item in localStorage with key == 'id_token'
return tokenNotExpired();
};
public logout() {
// Remove token from localStorage
localStorage.removeItem('id_token');
};
}
我注入了服务并配置了提供程序。Auth0Lock一切都正确连接，但即使定义它也找不到。每次它到达lock = new Auth0Lock('ID', 'DOMAIN', {});它的炸弹。
