Angular 离子3角5-罐'；t解析“的所有参数”；第页“；

出现错误“无法解析主页的所有参数：（[object]，？，[object object]，[object object]）”。我正试图通过angularfire访问我的数据库，用户登录时会在toastcontroller messeges上发送电子邮件。函数名：“IonViewWillLoad（）”

所有项目：

这是我的主页：

import { Component } from '@angular/core';
import { NavController, ModalController } from 'ionic-angular';
import { DetailPage } from '../detail/detail';
import { ToastController } from 'toast-controller';
import { AngularFireAuth } from "angularfire2/auth";
import { User } from '../../app/modals/user';
@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {
//public shouldReorder = false;
  user = {} as User;

  constructor(private aFAuth: AngularFireAuth,
              private toastCtrl = ToastController,
    public navCtrl: NavController,
              public modalCtrl: ModalController)
  {
    //this.service.getPeople().subscribe( data => {
  //    this.people = data.results
  //  });


  }


  ionViewWillLoad(){
    this.aFAuth.authState.subscribe(data => {
      if(data.email && data.uid) {
        let toast = this.toastCtrl.create({
          message: 'User was added successfully',
          duration: 3000,
          position: 'top'
        });

        toast.onDidDismiss(() => {
          console.log('Dismissed toast');
        });
        toast.present();
      }

      else {
        let toast = this.toastCtrl.create({
          message: 'User not found',
          duration: 3000,
          position: 'top'
        });
        toast.present();
      }
    });
  }
}

我不明白那是什么错误，也许有人能告诉我？IDE中不再有错误，只有浏览器中的错误（ionic serve）。

App.module.ts:

import { BrowserModule } from '@angular/platform-browser';
import { HttpClient, HttpClientModule } from "@angular/common/http";
import { ErrorHandler, NgModule } from '@angular/core';

User.ts:

import { AngularFireModule } from "angularfire2";
import { FIREBASE_CONFIG } from "./app.firebase.config";
import { LoginPage } from "../pages/login/login";
import { AngularFireAuthModule } from "angularfire2/auth";

    {provide: ErrorHandler, useClass: IonicErrorHandler},

  ]
})
export class AppModule {}

export interface User {
  email: string;
  password: string;

}

编辑：

当我从我的构造函数中删除-public navCtrl:NavController时（它没有被使用，错误变小了，但有点不同=？）：

---

无法解析主页的所有参数：（[对象对象]，？，[对象对象]）您正在分配

toastCtrl=ToastController

，而它应该是

私有toastCtrl:toastcroller

改变

来自

  constructor(private aFAuth: AngularFireAuth,
              private toastCtrl = ToastController,

至

  constructor(private aFAuth: AngularFireAuth,
              private toastCtrl : ToastController,

---

错误是因为angular无法访问

主页所需的所有参数。在构造函数中，您声明了四个参数：angular无法访问所有内容，除了
ToastController
。这就是错误消息中的参数是问号的原因

您必须正确地从
导入
toast-controller
，现在您正从
'toast-controller'
导入它，除非您在该位置有东西需要删除该行

import { ToastController } from 'toast-controller';

然后从ionic angular库正确导入ToastController。如下所示（更改代码的第二行）

你能将你的app.module.t添加到post app.module.ts和user.ts中吗？请同时发布主页。事情是我用那种方式做的，我的函数中的单词.create有错误“属性'create'在'typeof ToastController'中不存在，然后我更改为显示的内容。但现在当我再次写下这句话时，它起了作用。。有些奇怪的事，谢谢。
