求指教一个 redux 相关的问题，先谢过了

实际开发中，尤其是面向 c 端的用户，任何业务和用户操作我认为都应该包含这四种状态，loading，error，empty，success，为了简化 actionType 的分散性，所以就简单封装了一个 acitonModel

/** * generator common actionModel 普通模型 * @param {*} prefix 前缀，需要保证唯一性 */ export function generatorCommonActionModel(prefix) { const load_loading_action_type = prefix + common_load_loading; const load_empty_action_type = prefix + common_load_empty; const load_error_action_type = prefix + common_load_error; const load_success_action_type = prefix + common_load_success; const get_common_action_type = prefix + get_common; const reset_action_type = prefix + common_reset; return { prefix, load_loading_action_type, load_empty_action_type, load_error_action_type, load_success_action_type, get_common_action_type, reset_action_type, loadLoadingActionCreator: params => ({ type: load_loading_action_type, params }), loadEmptyActionCreator: params => ({ type: load_empty_action_type, params }), loadErrorActionCreator: params => ({ type: load_error_action_type, params }), loadSuccessActionCreator: (data, params) => ({ type: load_success_action_type, payload: { data, params } }), getCommonActionCreator: params => ({ type: get_common_action_type, params }), resetActionCreator: params => ({ type: reset_action_type, params }) } } 

actionModel 根据 key 的唯一性来区分，使用的时候直接使用该函数可以快速生成对应的 action 模型，实际运用中也确实感受到了其方便性，但随之带来的问题就来了，就是 reducer 层，始终想不到该如何去优化处理，目前的做法

/** * 统一处理 commonModelActions * @param {*} actionModel 需遵循 actionHelp 规范 * @param {*} stateModel 需遵循 stateModel 中的 commonStateModel 数据模型规范 * @param {*} action dispatch 出来的 action */ export function reducerGeneratorCommonActionModel(actionModel, stateModel, action) { switch (action.type) { case actionModel.load_loading_action_type: return { ...stateModel, load_status: NetWorkComponent.LOAD_LOADING }; case actionModel.load_empty_action_type: return { ...stateModel, load_status: NetWorkComponent.LOAD_EMPTY }; case actionModel.load_error_action_type: return { ...stateModel, load_status: NetWorkComponent.LOAD_ERROR }; case actionModel.load_success_action_type: return { ...stateModel, load_status: Array.isArray(action.payload.data) ? action.payload.data.length > 0 ? NetWorkComponent.LOAD_SUCCESS : NetWorkComponent.LOAD_EMPTY : NetWorkComponent.LOAD_SUCCESS, data: action.payload.data }; default: return stateModel; } } export default function (state = defaultState, action) { switch (action.type) { //当前城市广告位 case goodShopAdvertisingCommonActionModel.load_loading_action_type: case goodShopAdvertisingCommonActionModel.load_empty_action_type: case goodShopAdvertisingCommonActionModel.load_error_action_type: case goodShopAdvertisingCommonActionModel.load_success_action_type: return { ...state, advertisings: reducerGeneratorCommonActionModel(goodShopAdvertisingCommonActionModel, state.advertisings, action) } //当前城市的榜单列表 case goodShopRankingShopCommonActionModel.load_loading_action_type: case goodShopRankingShopCommonActionModel.load_empty_action_type: case goodShopRankingShopCommonActionModel.load_error_action_type: case goodShopRankingShopCommonActionModel.load_success_action_type: return { ...state, rankingShops: reducerGeneratorCommonActionModel(goodShopRankingShopCommonActionModel, state.rankingShops, action) } //当前城市的爆品秒杀商品列表 case goodShopSeckillCommodityCommonActionModel.load_loading_action_type: case goodShopSeckillCommodityCommonActionModel.load_empty_action_type: case goodShopSeckillCommodityCommonActionModel.load_error_action_type: case goodShopSeckillCommodityCommonActionModel.load_success_action_type: return { ...state, seckillCommoditys: reducerGeneratorCommonActionModel(goodShopSeckillCommodityCommonActionModel, state.seckillCommoditys, action) } //附近的商户 case goodShopNearbyShopListPagingActionModel.load_loading_action_type: case goodShopNearbyShopListPagingActionModel.load_empty_action_type: case goodShopNearbyShopListPagingActionModel.load_error_action_type: case goodShopNearbyShopListPagingActionModel.load_more_loading_action_type: case goodShopNearbyShopListPagingActionModel.load_more_empty_action_type: case goodShopNearbyShopListPagingActionModel.load_more_error_action_type: case goodShopNearbyShopListPagingActionModel.load_success_action_type: return { ...state, nearbyShops: reducerGeneratorListPagingActionModel(goodShopNearbyShopListPagingActionModel, state.nearbyShops, action) } //推荐的商户 case goodShopRecommendShopCommonActionModel.load_loading_action_type: case goodShopRecommendShopCommonActionModel.load_empty_action_type: case goodShopRecommendShopCommonActionModel.load_error_action_type: case goodShopRecommendShopCommonActionModel.load_success_action_type: return { ...state, recommendShops: reducerGeneratorCommonActionModel(goodShopRecommendShopCommonActionModel, state.recommendShops, action) } //人气商圈的商户 case goodShopHotShopListPagingActionModel.load_loading_action_type: case goodShopHotShopListPagingActionModel.load_empty_action_type: case goodShopHotShopListPagingActionModel.load_error_action_type: case goodShopHotShopListPagingActionModel.load_more_loading_action_type: case goodShopHotShopListPagingActionModel.load_more_empty_action_type: case goodShopHotShopListPagingActionModel.load_more_error_action_type: case goodShopHotShopListPagingActionModel.load_success_action_type: return { ...state, hotShops: reducerGeneratorListPagingActionModel(goodShopHotShopListPagingActionModel, state.hotShops, action) }; //人气商圈栏目分类 case goodShopHotShopClassifyCommonActionModel.load_loading_action_type: case goodShopHotShopClassifyCommonActionModel.load_empty_action_type: case goodShopHotShopClassifyCommonActionModel.load_error_action_type: case goodShopHotShopClassifyCommonActionModel.load_success_action_type: return { ...state, hotShopsClassify: reducerGeneratorCommonActionModel(goodShopHotShopClassifyCommonActionModel, state.hotShopsClassify, action) }; //榜单详情 case goodShopRankingShopDetailCommonActionModel.load_loading_action_type: case goodShopRankingShopDetailCommonActionModel.load_empty_action_type: case goodShopRankingShopDetailCommonActionModel.load_error_action_type: case goodShopRankingShopDetailCommonActionModel.load_success_action_type: return { ...state, rankingDetails: reducerMergeGeneratorCommonActionModel(goodShopRankingShopDetailCommonActionModel, state.rankingDetails, action) } //支持的城市列表 case goodShopCitysCommonActionModel.load_loading_action_type: case goodShopCitysCommonActionModel.load_empty_action_type: case goodShopCitysCommonActionModel.load_error_action_type: case goodShopCitysCommonActionModel.load_success_action_type: return { ...state, citys: reducerGeneratorCommonActionModel(goodShopCitysCommonActionModel, 

感觉这样去写，反而更累了，所以想问下 v 友门，这块要如何去设计和优化啊，再次感谢
