如何使用combineReducer

如何使用combineReducer拆分reducer呢？

1. 首先在组建中创建一个store的文件夹，其中reducer.js放该组件的数据代码
   
2. 然后在最外层的store文件夹中的reducer.js文件中使用combineReducer整合小组件的reducer代码

import { combineReducers } from "redux";
import headerReducer from '../common/header/store/reducer'
const reducer = combineReducers({
    header:headerReducer
});
export default reducer;
