Ember CLI - 在路由中注入服务并使用 ember-simple-auth 获取当前用户

Question

我正在使用 ember-simple-auth 进行身份验证。我已经创建了获取当前用户的服务。

//services/session.js
import Ember from 'ember';
import ESASession from "ember-simple-auth/services/session";

 export default ESASession.extend({

  store: Ember.inject.service(),

  setCurrentUser: function() {
    if (this.get('isAuthenticated')) {
      let user_id = this.get('session.content.authenticated.user_id');
      this.get('store').findRecord('user', user_id).then((user) => {
        this.set('currentUser', user);
      });
    }
  }.observes('isAuthenticated')
 });

在我注入会话时在控制器中工作

//controller/application.js
import Ember from 'ember';

export default Ember.Controller.extend({
  auth: Ember.inject.service('session'), 

  actions: {

    save() {
       var current_user = this.get('auth.currentUser');
       console.log(current_user) // I got the current user model
    }
  }
});

但是当我尝试在路线中使用相同的方法时，我的 current_user 未定义

//routes/application.js
import Ember from 'ember';
import ApplicationRouteMixin from 'ember-simple-auth/mixins/application-route-mixin';

export default Ember.Route.extend(ApplicationRouteMixin, {
  auth: Ember.inject.service('session'),

  model() {
    console.log(this.get('auth.currentUser')); // I got undefined
  }
 });

我需要获取当前用户，因为我想知道用户是否有is_admin标志，比如

afterModel: function(model, transition) {
    if (model.is_admin) {
        this.transitionTo('admin');
     }
}

在路由中注入会话的最佳方法是什么？我做错了什么？

Answer 1

你什么时候验证会话？在我看来，当模型挂钩被触发时，会话没有经过身份验证，这就是你未定义的原因。

Answer 2

我必须更改会话服务

//services/session.js
import Ember from 'ember';
import DS from 'ember-data';
import SessionService from "ember-simple-auth/services/session";

export default SessionService.extend({

  store: Ember.inject.service(),

  account: Ember.computed('session.content.authenticated.user_id', function() {
    const user_id =  this.get('session.content.authenticated.user_id');
    if (!Ember.isEmpty(user_id)) {
      return DS.PromiseObject.create({
        promise: this.get('store').findRecord('user', user_id)
      });
    }
  })
});

现在，我可以在路由中使用它了；例如，如果我想在用户具有首次登录标志时重定向

//routes/application.js
import Ember from 'ember';
import ApplicationRouteMixin from 'ember-simple-auth/mixins/application-route-mixin';

export default Ember.Route.extend(ApplicationRouteMixin, {

  session: Ember.inject.service(),

  sessionAuthenticated() {
    var applicationRouteInstance = this;
    this.get('session.account').then(function(user){
        if (user.get('is_first_login')) {
          applicationRouteInstance.transitionTo('users/password-reset');
        } else {
          applicationRouteInstance.transitionTo('dashboard');
        }
      });
   }

});
