ionic 数据刷新路由解决办法

版权声明： https://blog.csdn.net/weixin_41404460/article/details/82148772

官网给出的都是navCtrl方法，其他地址也都是给出的是什么路由视图刷新。试了好久，没有试出来。今天获得谷歌大神的支持，得知 modal方法需要 modal自身关闭后进行回调：

//因为modal关闭的时候，不会再次触发父页面的ionViewDidEnter();

故而补充的更多页面ts代码如下：

import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams, ModalController, LoadingController } from 'ionic-angular';
import { LoginPage } from '../login/login';
import { Storage } from '@ionic/storage';
import { BaseUI } from '../../common/baseui';
import { RestProvider } from '../../providers/rest/rest';
import { UserPage } from "../user/user";

/**
 * Generated class for the MorePage page.
 *
 * See https://ionicframework.com/docs/components/#navigation for more info on
 * Ionic pages and navigation.
 */

// @IonicPage()
@Component({
  selector: 'page-more',
  templateUrl: 'more.html',
})
export class MorePage extends BaseUI {

  public notlogin: boolean = true;
  public logined: boolean = false;
  headface: string;
  userinfo: string[];

  constructor(public navCtrl: NavController,
    public navParams: NavParams,
    public modalCtrl: ModalController,
    public loadingCtrl: LoadingController,
    public rest: RestProvider,
    private storage: Storage) {
    super();
  }

  ionViewDidLoad() {
    //console.log('ionViewDidLoad MorePage');
  }

  showmodel() {
    const modal = this.modalCtrl.create(LoginPage);

    //关闭后的回调
    //因为modal关闭的时候，不会再次触发父页面的ionViewDidEnter();
    
    modal.onDidDismiss(()=>{
      this.loadUserPage();
    })

    modal.present();
  }

  ionViewDidEnter() {
    this.loadUserPage();
  }

  loadUserPage() {
    this.storage.get('UserId').then((val) => {
      // console.log('Your age is', val);
      if (val != null) {
        //加载用户数据
        var loading = super.showLoading(this.loadingCtrl, "加载中...");
        this.rest.getUserInfo(val).subscribe(
          userinfo => {
            this.userinfo = userinfo;
            this.headface = userinfo["UserHeadface"] + "?" + (new Date()).valueOf();
            this.notlogin = false;
            this.logined = true;

            loading.dismiss();

          }
        );

        // this.notlogin = false;
        // this.logined = true;
        // alert("已登录");
      } else {
        this.notlogin = true;
        this.logined = false;
        // alert("未登录");
      }
    });

  }


  gotouserpage() {
    this.navCtrl.push(UserPage)


  }

}
