使用combineReducers完成数据的拆分管理

以header组件为例

在header组件下建立store,通过index.js将store里的所有js导出

在总的reducer中引入header组件的reducers

import { combineReducers} from 'redux'
import {reducer as headerRuducer} from '../common/header/store/'

const reducer = combineReducers({
    header: headerRuducer
});
export default reducer;
