在@connect装饰器回调中存储参数

Question

我是React + Redux的新手。我很困惑为什么redux状态对象不直接暴露给存储，而是通过store.userReducer。

这是我的连接装饰

 @connect((store) => {

 return {
   users: store.userReducer.users
//users: store.users
    }
})

这是combineReducers

import {combineReducers} from "redux";

import userReducer from "./usersReducer";

export default combineReducers({
  userReducer
})

这是userReducer的相关部分

export default function reducer(state={
users:[],
fetching: false,
fetched: false,
error: null
}, action){
switch (action.type) {
  case "FETCH_USERS":{
  return {...state, fetching: true}
 }

这是商店的一部分

const middleware = applyMiddleware(promise(),thunk);
export default createStore(reducers,middleware);
