用法：
下载包进行安装，store主入口，hooks简化store(复制粘贴进去即可)，slice相当于store中的模块化，最后在页面根入口导入store，并使用即可

1、安装

npm install @reduxjs/toolkit react-redux -D

2、目录结构

store.ts

import { configureStore } from '@reduxjs/toolkit'
import userSlice from './slice/userSlice';
import mySlice from './slice/mySlice';export  const store = configureStore({reducer: {userSlice,mySlice},middleware:getDefaultMiddleware => getDefaultMiddleware({//关闭redux序列化检测, 异步函数请求接口时，返回的对象无法序列化serializableCheck:false})})// 从 store 本身推断出 `RootState` 和 `AppDispatch` 类型
export type RootState = ReturnType<typeof store.getState>
// 推断出类型: {posts: PostsState, comments: CommentsState, users: UsersState}
export type AppDispatch = typeof store.dispatch

hooks.ts

import { TypedUseSelectorHook, useDispatch, useSelector } from 'react-redux'
import type { RootState, AppDispatch } from './store'// 在整个应用程序中使用，而不是简单的 `useDispatch` 和 `useSelector`
export const useAppDispatch: () => AppDispatch = useDispatch
export const useAppSelector: TypedUseSelectorHook<RootState> = useSelector

slice.ts

import { PayloadAction, createAsyncThunk, createSlice } from "@reduxjs/toolkit";
import axios from 'axios';
const initialState:{userId:string
}  = {userId:"1"
}
export const userSlice = createSlice({name:"user",initialState,reducers:{increment:(state,action:PayloadAction<string>)=>{console.log(action)state.userId = action.payload}},extraReducers:(build)=>{// 异步请求fulfilled后要做的事build.addCase(getApiInfo.fulfilled,(state,action)=>{state.userId = action.payload.data.data.id;});build.addCase(getApiInfo2.fulfilled,(state,action)=>{state.userId = action.payload.data.data.id;})}
});
// 异步请求
export const getApiInfo = createAsyncThunk('getApi', async()=>{const info = await axios('https://13123/111/22',{method:'POST',headers:{"Sessionid":""}});return info
});
export const getApiInfo2 = createAsyncThunk('bbbbbbbb', async()=>{const info = await axios('https://13123/111/22',{method:'POST',headers:{"Sessionid":""}});return info
})
export const { increment } = userSlice.actions;
export default userSlice.reducer

index.tsx(页面入口处)

import { createRoot } from 'react-dom/client';
import RouterRender from './router/RouterRender';
import { RouterProvider } from 'react-router-dom';
import { Provider } from 'react-redux';
import { store } from '@/redux/store'
const root = createRoot(document.getElementById('root') as HTMLElement
);
root.render(<Provider store={store}><RouterProvider router={RouterRender}></RouterProvider></Provider>
);

完工
