13 |导出默认的createStore（rootReducers，composeWithDevtools（applyMiddleware（thunk）））

reducers.js

import { GET_ALL_POSTS, GET_ALL_SPECIALITIES, GET_ALL_COURSES, GET_ALL_TEACHERS,
    GET_POST, GET_SPECIALITY, GET_LESSON, GET_COURSE } from "./actions"

export const postReducer = (state = {}, action) => {
    if(action.type === GET_ALL_POSTS){
        return {
            ...state,
            posts: action.posts
        }
    }

    if(action.type === GET_POST){
        return {
            ...state,
            post: action.post
        }
    }
    return state
}

export const specialityReducer = (state = {}, action) => {
    if(action.type === GET_ALL_SPECIALITIES){
        return {
            ...state,
            specialities: action.specialities
        }
    }

    if(action.type === GET_SPECIALITY)
        return {
            ...state,
            speciality: action.speciality
        }

    return state
}

export const courseReducer = (state = {}, action) => {
    if (action.type === GET_ALL_COURSES){
        return {
            ...state,
            courses: action.courses
        }
    }
    if (action.type === GET_COURSE){
        return {
            ...state,
            course: action.course
        }
    }

    return state
}

export const teacherReducer = (state = {}, action) => {
    if(action.type === GET_ALL_TEACHERS){
        return {
            ...state,
            teachers: action.teachers

    return state

export const lessonReducer = (state = {}, action) => {
    if (action.type === GET_LESSON){
        return {
            ...state,
            lesson: action.lesson
        }
    }
    return state
}

store.js

import { createStore, combineReducers, applyMiddleware } from 'redux'
import { composeWithDevtools } from 'redux-devtools-extension'
import thunk from 'redux-thunk'
import { postReducer, 
    specialityReducer, 
    courseReducer, 
    teacherReducer, 
    lessonReducer 
} from './reducers'



export default createStore(combineReducers({postReducer, specialityReducer, courseReducer, teacherReducer, lessonReducer}),composeWithDevtools(applyMiddleware(thunk)))

Answer 1

尝试将对象传递给CombineReducers，并在所有reducer之前给出名称。 CombineReducers（{reducerName：reducerFunction}）;

使用React.js存储错误-TypeError：Object（...）不是函数react
