存token 

import { defineStore } from 'pinia';export const userInfo = defineStore('userInfo', {state: () => {return {userToken: uni.getStorageSync('token') || '',};},actions: {// 添加tokenupdateToken(token: string) {uni.setStorageSync('token', token);this.userToken = token}}
});

使用

 import {userInfo} from '@/stores/userInfo'import {ref} from "vue";const test = userInfo()const tst = ref('4')test.updateToken(tst.value)

效果

这边存 用户信息

定义store 文件

import { defineStore } from 'pinia'interface Member {userInfo : AnyObject | null
}const useMemberStore = defineStore('member', {state: () : Member => {return {userInfo: uni.getStorageSync('userInfo') || null}},actions: {updateUserInfo(userInfo : AnyObject) {uni.setStorageSync('userInfo', userInfo)this.userInfo = userInfo}}
})export default useMemberStore

 vue页面 存储数据

import useMemberStore from '@/stores/member'const user = useMemberStore()user.updateUserInfo('存对象的数据')   

取数据

在template中 使用 userInfo.member_id

 import { storeToRefs } from 'pinia'import useMemberStore from '@/stores/member'    const info = useMemberStore()const { userInfo } = storeToRefs(info)console.log(userInfo.value.member_id, '从缓存中取数据');

打印下 userInfo
