uniapp使用pinia存储（vue3+ts）

1.安装pinia和持久化插件

npm install pinia

npm install pinia-plugin-persistedstate

2.main.ts 文件中配置该插件

import { createSSRApp } from "vue";
import App from "./App.vue";
import { createPinia } from 'pinia';
import piniaPersistedState from 'pinia-plugin-persistedstate';
import TopNavigation from "./compontens/topNavigation.vue";

export function createApp() {
  const pinia = createPinia();
  // 配置持久化插件
  pinia.use(piniaPersistedState);
  const app = createSSRApp(App);
  app.component('top-nav', TopNavigation)
  app.use(pinia)
  return {
    app,
  };
}

3.新建文件src/store/logintoken.ts

import { defineStore } from 'pinia';
import { ref } from "vue";
export const useLogintokenStore = defineStore('logintoken', () => {
    // 会员信息
    const profile = ref()

    //定义一个函数来保存信息，本地缓存
    const setProfile = (val: any) => {
        profile.value = val
    }
    //定义一个函数来修改清理会员信息，清除全部存储
    const clearProfile = () => profile.value = undefined
    // 定义一个函数来修改或新增 profile 里面的值
    const setProfileValue=(key: string, value: any)=> {
        // 直接通过键名设置或更新值，如果键名不存在则新增
        profile.value[key] = value;
    }
    // 定义一个函数来修改 profile 里面的值
    const updateProfileValue = (key: string, value: any) => {
        if (key in profile.value) {
            // 如果键名存在于 profile 中，则更新其值
            profile.value[key] = value;
            console.log(profile)
        } else {
            console.warn(`Key "${key}" does not exist in profile.`);
        }
    }
    // 定义一个函数来删除 profile 里面的值
    const deleteProfileValue = (key: string) => {
        if (key in profile.value) {
            // 如果键名存在于 profile 中，则删除该属性
            delete profile.value[key];
            console.log(profile)
        } else {
            console.warn(`Key "${key}" does not exist in profile.`);
        }
    }

    //记得 return
    return { profile, setProfile, clearProfile, updateProfileValue, deleteProfileValue,setProfileValue }
},
    {
        persist: {
            storage: {
                getItem(key) {
                    return uni.getStorageSync(key)
                },
                setItem(key, value) {
                    uni.setStorageSync(key, value)
                },
            }
        }
    });

4.使用

存

import { useLogintokenStore } from '@/stores/logintoken'

let msg = {
 idserveUserId: res.result.userId,
 isFollowedWeChat: res.result.isFollowedWeChat,
 openId: res.result.openId,
          }
const memberStore=useLogintokenStore()
 memberStore.setProfile(msg)

清除

const memberStore=useLogintokenStore()
 memberStore.clearProfile()
