[AppComponent的ngOninit钩子没有在页面刷新上被调用

Question

我导航到/posts（localhost:4200/posts），但是当我刷新页面时ngOnInit()的页面AppComponent没有被调用。

Answer 1

import { Component, OnInit } from '@angular/core';

export class App implements OnInit {
  constructor() {
     // Called first time before the ngOnInit()
  }

  ngOnInit() {
     // Called after the constructor and called  after the first ngOnChanges() 
  }
}
is this the same way you have implemented in your project?
