如果Angular 9中的HTTP响应代码是200，如何将用户从登录页面导航到主页

import { Component } from '@angular/core';
import { Router } from '@angular/router';

@Component({
  selector: 'app-login',
  template: `
    <!-- 登录表单 -->
    <form (ngSubmit)="login()">
      <!-- 表单字段 -->
      <input type="text" [(ngModel)]="username" name="username" placeholder="用户名">
      <input type="password" [(ngModel)]="password" name="password" placeholder="密码">
      <button type="submit">登录</button>
    </form>
  `,
})
export class LoginComponent {
  username: string;
  password: string;

  constructor(private router: Router) {}

  login() {
    // 假设登录成功后，服务器返回200
    const responseCode = 200;

    if (responseCode === 200) {
      // 导航到主页
      this.router.navigate(['/home']);
    } else {
      // 处理登录失败的情况
    }
  }
}
