Question

我是离子和角框架的新手。我启动了一个引用Auth login

的项目

按照所有步骤操作后，我仍然遇到错误，因为这是我无法解决的新框架。

代码

login.page.ts

    import { AuthenticationService } from './../../services/authentication.service';
import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-login',
  templateUrl: './login.page.html',
  styleUrls: ['./login.page.scss'],
})
export class LoginPage implements OnInit {

  constructor(private authService: AuthenticationService) { }

  ngOnInit() {
  }

  login() {
    this.authService.login();
  }

}

和login.page.html

<ion-header>
  <ion-toolbar>
    <ion-title>Login</ion-title>
  </ion-toolbar>
</ion-header>

<ion-content padding>
  <ion-button (click)="login()" expand="block">Login</ion-button>
  <ion-button expand="block" color="secondary" routerLink="/register" routerDirection="forward">Register</ion-button>
</ion-content>

加载页面时出现此错误：

PS：我有2个文件， 1：login.page.html，

2：login.module.ts

看起来您正在循环调用一个函数，或者您可能错过了登录模块中的导入路由器模块，请再次进行检查。

错误RangeError：超出最大调用堆栈大小，core.js：15724
