商店未在“操作”中定义

Question

所以，我想使用另一个名为UserStore的商店的存储数据。操作为FavoriteActions，FavoriteStore。如果我在UserStore.getState()上的某个方法中调用FavoriteActions，则会显示UserStore.getState is not a function。很奇怪，我有一个使用UserStore的类似代码，它可以工作。我已经在文件的顶部要求它了。

这是文件。

var alt = require('../utils/alt');

var UserStore = require('../stores/UserStore');

var FavoriteActions = alt.createActions({

  favorite: function(variant_id, list_id) {
    this.dispatch();
    # THIS IS THE PROBLEM
    var token = UserStore.getState().current_user.token;
    var headers = { 'X-Spree-Token': token };
    var params = {
      variant_id: variant_id
    };

    axios.get(base_url + '/shopping_lists/' + list_id + '/items', {
      headers: headers,
      params: params
    })
    .then(FavoriteActions.updateFavorite)
    .catch(FavoriteActions.favoritesFailed);
  },

  updateFavorite: function(result) {
    this.dispatch(result);
  },

  updateFavoriteId: function(list_id) {
    this.dispatch(list_id);
  },

  updateFavorites: function(result) {
    this.dispatch(result);
  },

  favoritesFailed: function(error_message) {
    this.dispatch(error_message);
  },
});

module.exports = FavoriteActions;

我正在使用alt。这是UserStore文件。

var alt = require('../utils/alt');
var UserActions = require('../actions/UserActions');

var UserStore = alt.createStore({
  displayName: 'UserStore',

  bindListeners: {
    login: UserActions.LOGIN,
    logout: UserActions.LOGOUT,
    updateUser: UserActions.UPDATE_USER,
    clearUser: UserActions.CLEAR_USER,
    loginFailed: UserActions.LOGIN_FAILED
  },

  state: {
    current_user: null,
    errorMessage: null,
    loading: false
  },

  login: function() {
    this.setState({
      loading: true
    });
  },

  updateUser: function(user) {
    this.setState({
      current_user: user,
      loading: false
    });
  },

  logout: function() {
    this.setState({
      loading: true
    });
  },

  clearUser: function() {
    this.setState({
      current_user: null,
      loading: false
    });

  // FIXME: Unset user session
  },

  loginFailed: function(errorMessage) {
    this.setState({
      errorMessage: errorMessage,
      loading: false
    });
  }
});

module.exports = UserStore;
