1、安装依赖

npm i react-redux @reduxjs/toolkit

2、在store/modules文件夹中新建todo.js （billSlice.js）

// 账单列表
import { createSlice } from '@reduxjs/toolkit'
import axios from 'axios'

const billStore = createSlice({
    name: 'billStore',
    // 数据状态
    initialState: {
        billList: []
    },
    reducers: {
        // 同步修改方法
        setBillList(state, action) {
            state.billList = action.payload
        }
    }
})

// 解构
const { setBillList } = billStore.actions

// 编写异步
const getBillList = () => {
    return  async (dispatch) => {
        // 异步请求
        const res = await axios.get('http://localhost:8888/ka')

        // 调用同步方法
        dispatch(setBillList(res.data))
    }
}

export {
    getBillList
}

// 导出reducers
const reducer = billStore.reducer

export default reducer

3、在store文件夹中创建index.js，配置上一步创建的todo.js

import { configureStore } from '@reduxjs/toolkit';
import billReducer from './modules/billStore';

const store = configureStore({
    reducer: {
        bill: billReducer,
    },
})
export default store;

4. 在项目根目录的index.js文件中配置启动项

import React from 'react';
import ReactDOM from 'react-dom/client';

import { RouterProvider } from 'react-router-dom'
import { Provider} from 'react-redux'
import store from './store'
import router from '@/router'
// 导入定制样式
import './theme.css'

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
    <Provider store={store}>
        <RouterProvider router={router} >

        </RouterProvider>
    </Provider>
);

5. 配置完成后，开始使用redux

使用redux的时候有两个不能忘记的钩子函数useSelector,useDispatch；
useSelector是获取store内定义的状态值的钩子函数；
useDispatch是获取store内定义的方法的钩子函数。

import { Outlet } from "react-router-dom";
import { Button } from "antd-mobile";
import { useEffect } from "react";
import { useDispatch, useSelector } from "react-redux";
import { getBillList } from "@/store/modules/billStore";

const Layout = () =>{
    // 获取store方法
    const dispatch = useDispatch();
    useEffect(()=>{
        dispatch(getBillList())
    },[dispatch])

    // 获取store状态值
    const { billList } = useSelector((state) => state.billStore);
    console.log(billList)
    
    return (
        <div>
            <h1>Layout</h1>
            <Button color='primary' fill='solid'>
                Solid
            </Button>
            <Outlet />
        </div>
    )
}
export default Layout;
