补救状态没有效果

Question

我试图创建一个存储，但由于某种原因，当我更改初始状态常量时，初始状态没有改变：这是初始状态为的减速器

import { GET_PRODUCT_BY_NAME, ADD_PRODUCT_TO_CART, CLEAR_CART, DELETE_ITEM, CURRENT_PRODUCT,INCREASE_AMOUNT } from '../../actionTypes'
const INITIALSTATE = {
currentProduct:{},
product: {},
list:[]
}

export  function ProductReducer(state = INITIALSTATE, action) {
const { type, payload } = action

switch (type) {
case GET_PRODUCT_BY_NAME:
return {
...state,
user: payload.user,
}
case ADD_PRODUCT_TO_CART:
return {
...state,
list: [...state.list,payload]
}

case CLEAR_CART:
return {
list: []
}
case DELETE_ITEM:
console.log()
return {
list:[...state.list.slice(0, action.payload),
...state.list.slice(action.payload + 1)]
}
case CURRENT_PRODUCT:
return {
...state,
currentProduct: payload
}
case INCREASE_AMOUNT:

return {

...state,

}

default:
return state
}
}

这是包含商店配置详细信息的文件：

import { createStore, applyMiddleware } from 'redux'
import { persistStore, persistReducer } from 'redux-persist'
import ReduxThunk from 'redux-thunk'
import storage from 'redux-persist/lib/storage'
import rootReducer from './rootReducers'
const persistConfig = {
key: 'root',
storage,
}
const persistedReducer = persistReducer(persistConfig, rootReducer)
let store = createStore(persistedReducer, applyMiddleware(ReduxThunk))
let persistor = persistStore(store)
export { store, persistor }

这是我在console.log状态时得到的结果：console.log

这个结果来自旧版本的

您遇到了这个问题，因为在确定Product reducer初始状态应该是什么样子之前，您已经应用了持久性。要解决此问题，您需要将reducer临时包含在persistConfig黑名单中，或者将stateReconciler设置为autoMerge。
