## 7.求和案例_react-redux开发者工具的使用
    (1).npm install @redux-devtools/extension
    (2).store中进行配置
        import { composeWithDevTools } from '@redux-devtools/extension';
        export default createStore(allReducer,composeWithDevTools(applyMiddleware(thunk)))

• src/redux/store.js

/*
*  该文件专门用于暴露一个store对象，整个应用只有一个store对象
* */

// store.js
//引入createStore，专门用于创建redux中最为核心的store对象
import {createStore,applyMiddleware,combineReducers} from 'redux'
//引入为Count组件服务的reducer
import countReducer from './reducers/count'
//引入为Person组件服务的reducer
import personReducer from './reducers/person'
//引入redux-thunk，用于支持异步action
import {thunk} from 'redux-thunk'
//引入redux-devtools-extension
import { composeWithDevTools } from '@redux-devtools/extension';

// 合并多个reducer
const allReducer = combineReducers({
    he:countReducer,
    rens:personReducer
})
//导出store
export default createStore(allReducer,composeWithDevTools(applyMiddleware(thunk)))
