ionic 3 deeplinking for reset password

由 安稳与你 提交于 2019-12-07 17:39:27
I am creating a mobile application using ionic 3. I need to know the logic to implement reset password functionality. till now, i am able to send an email with reset token to the user. I was thinking that id user clicks on the link in the email, if app is installed then it should open the application page dedicated for reset password. So i did a little research and found that it can be done using DeepLinking ( custom url to respond) like myApp://resetPassword/{token} Now the problem is in gmail when you send link with custom url, it removes the href option. Can some one tell me slight

Why observable.subscribe works only from constructor

由 ⅰ亾dé卋堺 提交于 2019-12-07 09:25:14
问题 While working on Ionic 3 app I have faced problem that when you subscribe to observable from service in ngOnInit and update a local variable into it, it does not update the view. For e.g HTML template <p>{{myVariable}}</p> constructor(myService: MyService) { } ngOnInit() { this.myService.myObservable.subscribe((data) => { this.myVariable = data; }); } But when you do same thing from constructor, it works. contructor(myService: MyService) { this.myService.myObservable.subscribe((data) => {
