vue3引入pinia

1、npm install pinia

2、在项目目录建store文件夹创index.js

import { createPinia,defineStore } from "pinia";
const pinia = createPinia()
pinia.state.value
const token = defineStore('token',{
    state(){
        return {
            token: null
        }
    }
})
// ...可定义多个
export {token}
export default pinia

 3、其他页面使用存取

import {token} from "../store";
import {storeToRefs} from 'pinia'
let token1 = token();

let token2 = storeToRefs(token())

存token

token1.token = '123456'

取token

console.log(token2.token.value) // 123456
