Question

我正在创建一个简单的聊天应用程序。我有三个实体：房间，消息和用户。我有一个伪造的API，它返回的响应是这样的：

log4j:ERROR Could not read configuration file from URL [file:./bin/../config/log4j.properties].
java.io.FileNotFoundException: ./bin/../config/log4j.properties (No such file or directory)

我的动作如下：

[{
  id: 1,
  name: 'room1',
  avatar: 'some img url',
  messages: [
      {
        id: 1,
        text: 'some text',
        user: {
          id: 1,
          username: 'Peter Peterson',
          avatar: 'some img url'
      }
  ]
 }]

我的突变看起来像这样：

getAllRooms({ commit }) {
  commit(GET_ALL_ROOMS_REQUEST);
  return FakeApi.getAllRooms()
    .then(
      rooms => {
        const { entities } = normalize(rooms, room);
        console.log(entities);
        commit(GET_ALL_ROOMS_SUCCESS, {
          rooms: entities.rooms, byId: rooms.map(room => room.id)
        });
        commit(GET_ALL_MESSAGES_SUCCESS, { messages: entities.messages });
        commit(GET_ALL_USERS_SUCCESS, { users: entities.users });
      },
      err => commit(GET_ALL_ROOMS_ERROR)
    )
}

我的组件将这样调用操作：

[GET_ALL_ROOMS_REQUEST](state) {
  state.loading = true;
},
[GET_ALL_ROOMS_SUCCESS](state, payload) {
  state.rooms = payload.rooms;
  state.byId = payload.byId;
  state.loading = false;
},
[GET_ALL_ROOMS_ERROR]() {
  state.error = true;
  state.loading = false;
}

这些是我的架构定义：

{
  mounted() {
    this.getAllRooms();
  }
}

当我在FakeApi.getAllRooms（）之后的then方法中检查响应时，每个对象都包裹在某个怪异的Observer中，并且像这样通过它进行归一化和归一化返回一些怪异的响应。

我在做什么错了？

问题不在于vuejs，而是我制作normalizr模式的方式。因为我的响应是从根开始的数组，所以我应该有一个新的const series_0 = [{ 'value': 3000, 'name': '2016-09-20T20:23:48.426Z' }, { 'value': 6000, 'name': '2016-09-21T08:58:04.100Z' }, { 'value': 4000, 'name': '2016-09-21T05:21:08.317Z' }, { 'value': 6000, 'name': '2016-09-19T11:26:36.302Z' }, { 'value': 5000, 'name': '2016-09-16T11:26:19.165Z' }] const series_1 = [{ 'value': 3000, 'name': '2016-09-20T20:23:48.426Z' }, { 'value': 1500, 'name': '2016-09-21T08:58:04.100Z' }, { 'value': 8000, 'name': '2016-09-19T11:26:36.302Z' }, ] //make sure the longer array is the outer for-loop-variable const s0 = series_0.length >= series_1.length ? series_0 : series_1; const s1 = series_0.length >= series_1.length ? series_1 : series_0; let res = []; for (const s of s0) { let resObj = {name: s.name, value: s.value}; for (const t of s1) { if (s.name === t.name) { resObj.value+=t.value } } res.push(resObj); } console.log(res);数组架构，如下所示：

rooms

然后像这样使用它：const user = new schema.Entity('users'); const message = new schema.Entity('messages', { user: user }); const room = new schema.Entity('rooms', { messages: [message] }); const roomsSchema = [room];

Vuex-Normalizr无法正常工作
