为什么这个action.type在我的React/Redux应用程序的Reducer中没有触发？

Question

完全难倒，我有一个行动，设置一个状态 - isAuthenticated布尔和用户对象的基础上，用户是否登录或不。

动作肯定是射击中，auth减速运行正常，但这种情况是不被触发，因此状态不更新：

操作：

export const SET_CURRENT_USER = 'SET_CURRENT_USER' 

export function setCurrentUser (user) { 
    console.log(SET_CURRENT_USER) 
    return { 
    type: SET_CURRENT_USER, 
    user 
    } 
} 

减速

import isEmpty from 'lodash/isEmpty' 
import SET_CURRENT_USER from '../actions/authActions' 

const INITIAL_STATE = { 
    isAuthenticated: false, 
    user: {} 
} 

export default function (state = INITIAL_STATE, action) { 

     // console.log('action.type = ', action.type) <<< This is outputting the correct action type: SET_CURRENT_USER 
     switch (action.type) { 
     case SET_CURRENT_USER: 
      console.log('set cur user reducer') // this is not running 
      console.log(!isEmpty(action.user)) // this is not running 
      return { 
      isAuthenticated: !isEmpty(action.user), 
      user: action.user 
      } 
     default: 
      return state 
     } 
    } 

UPDATE 动作被称为上登录，并在根index.js与文件：

store.dispatch(setCurrentUser(jwt.decode(localStorage.getItem('token')))) 

商店设置如下： Index.js：

const store = configureStore() 

configureStore。 JS：

import { createStore, applyMiddleware } from 'redux' 
import thunk from 'redux-thunk' 

import rootReducer from './reducers/index' 

const configureStore =() => { 
    const store = createStore(
    rootReducer, 
    window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__(), 
    applyMiddleware(thunk) 
) 
    return store 
} 

export default configureStore 

根减速机：

import { combineReducers } from 'redux' 
import { routerReducer } from 'react-router-redux' 

import auth from './auth' 
import transactions from './transactions' 
import expenditure from './expenditure' 
import income from './income' 

const rootReducer = combineReducers({ 
    auth, 
    transactions, 
    expenditure, 
    income, 
    routing: routerReducer 
}) 

export default rootReducer

你能为SET_CURRENT_USER也做了控制台日志它不会导出默认所以应该用进口花括号

import { SET_CURRENT_USER } from '../actions/authActions'
