Emberjs：有条件过渡到路线

Question

我正在尝试在router.js中进行条件转换。我需要根据另一个休息服务返回的布尔值来确定条件（哪个是合格）。我可以编写一个函数来确定router.js中的值以及如何使用该值将我的转换重定向到两个单独的路由。如果eligibity为真，我需要做'this.route（'coverage'，{path：'/'}）;否则this.route（'inEligible'，{path：'/'}）; “请举个例子。我很贪图。

我在我的路线中使用这种模式：

import Route from '@ember/routing/route';
import { inject as service } from '@ember/service';


export default class SettingsRoute extends Route {
  @service currentUser;

  async beforeModel() {
    // inside the service, I have logic for checking if the user
    // authenticated, not expired, and fetched
    const isLoggedIn = await this.currentUser.isLoggedIn();

    if (!isLoggedIn) {
      this.transitionTo('setup');
      return;
    }
  }
}

如果你使用非本地类：

import Route from '@ember/routing/route';
import { inject as service } from '@ember/service';


export default Route.extend({
  currentUser: service();

  async beforeModel() {
    // inside the service, I have logic for checking if the user
    // authenticated, not expired, and fetched
    const isLoggedIn = await this.currentUser.isLoggedIn();

    if (!isLoggedIn) {
      this.transitionTo('setup');
      return;
    }
  }
});
