EmberFire身份验证和ToriiFirebaseAdapter

Question

我已经按照EmberFire 指南设置了torii 提供程序的身份验证,它运行正常.我希望在用户通过身份验证后将用户数据存储在firebase中,并在整个应用程序中访问用户对象.

我以前用ember做了一段时间,但我不确定如何使用新的torii提供程序.

我想我应该测试用户是否已经在初始化函数中存储在firebase中,然后将用户注入控制器/路由.

任何帮助我指向正确方向的帮助都会有所帮助,或者是一些示例代码.

谢谢

你需要一个牌坊适配器实现open和fetch和做了find/ save你的应用程序特定的用户模型.我们ToriiFirebaseAdapter并没有这样做,但.我已经走了,为你敲了一个会起作用的:

// app/torii-adapters/application.js

import Ember from 'ember';

export default Ember.Object.extend({
  firebase: Ember.inject.service(),
  store: Ember.inject.service(),

  /**
   * Executed after Firebase authentication.
   *
   * Find or create the user based on the Firebase `authData`
   *
   * @param  {Object} authData
   * @return {Promise<Object>} Updated session info
   */
  open(authData) {
    return this._findOrCreateUser(authData)
      .then((user) => {
        return { currentUser: user };
      });
  },

  /**
   * Fetch an existing Firebase auth session and place into `session.currentUser`
   *
   * @return {Promise<Object>} Updated session info
   */
  fetch() {
    let ref = this.get('firebase');
    let authData = ref.getAuth();

    if (!authData) {
      return Ember.RSVP.Promise.reject(new Error('No Firebase session found'));
    }

    return this._findOrCreateUser(authData)
      .then((user) => {
        return { currentUser: user };
      });
  },

  /**
   * Teardown a session. Remove the `session.currentUser`.
   *
   * @return {Promise<Object>} Updated session info
   */
  close() {
    this.get('firebase').unauth();
    return Ember.RSVP.Promise.resolve({ currentUser: null });
  },

  /**
   * Find the user with the given `authData`, create if not found
   *
   * @param  {Object} authData
   * @return {Promise<Object>} The user
   */
  _findOrCreateUser(authData) {
    let store = this.get('store');

    return store.find('user', authData.uid)
      .catch(() => {
        let newUser = store.createRecord('user', this.extractUserProperties(authData));

        return newUser.save();
      });
  },

  /**
   * Extract the user properties from `authData` that you care about.
   *
   * @param  {Object} authData
   * @return {Object} An updated property hash
   */
  extractUserProperties(authData) {
    var name = 'Unknown';
    var provider = authData.provider;
    var userData = authData[provider];

    if (userData.displayName) {
      name = userData.displayName;
    } else if (userData.username) {
      name = userData.username;
    }

    return {
      id: authData.uid,
      name: name,
      email: userData.email || null
    };
  }
});

您需要做的就是更新extractUserProperties方法以将您关注的属性放入用户模型的正确位置 - 每个人都以不同方式实现其用户模型.

现在您应该能够查找session.currentUser并返回与登录用户对应的Ember Data模型.

希望有所帮助.我们正在将此添加到网站文档中,并将尝试找到将其转换为EmberFire提供的ToriiFirebaseAdapter的方法.
