无法获取在我的 react-redux 应用程序的选择器中使用不可变 fromJS 定义的状态

Question

这是我的 Login 组件选择器文件

import { createSelector } from 'reselect';
const authentication = () => (state) => state.get('login');
const getCurrentAuthData = () => createSelector(
  authentication,
  (loginState) => loginState.get('currentUser')
);
export {
  authentication,
  getCurrentAuthData,
};

这是描述 Login 组件状态的 reducer 文件

import { fromJS } from 'immutable';
import { loginConstants } from './constant';

let user = JSON.parse(localStorage.getItem('user'));
const initialState = user ? fromJS({ loggedIn: true, user }) : fromJS({});

function loginReducer(state = initialState, action) {
   switch (action.type) {
   case loginConstants.LOGIN_REQUEST:
       return state
          .set('loggingIn', true)
          .set('user', action.true)
   case loginConstants.LOGIN_SUCCESS:
       return state
          .set('loggedIn', true)
          .set('user', action.true)
  case loginConstants.LOGIN_FAILURE:
       return fromJS({});
  case loginConstants.LOGOUT_REQUEST:
       return fromJS({});
  case loginConstants.LOGOUT_SUCCESS:
       return fromJS({});
  case loginConstants.LOGOUT_FAILURE:
       return fromJS({});
  default:
       return state
  } 
 }

 export default loginReducer;

现在问题是它给出了错误，因为 loginState.get 不是一个函数。

PS 我正在参考 React-boilerplate [https://github.com/react-boilerplate/react-boilerplate] 代码和基本上复制粘贴代码（学习阶段）。

问题解决，果然是语句写错了。我从

更改了语句

const authentication = () => (state) => state.get('login');
//here it is returning a function to authentication

至

const authentication = (state) => state.get('login');
//here it is returning `state.get('login')` to authentication
