在项目根路径下创建的stores文件夹中创建user.js文件 

并将以下内容复制到user.js中

import {ref} from "vue"
import { defineStore } from 'pinia';
const uniIdCo = uniCloud.importObject("uni-id-co")
const db = uniCloud.database();
const usersTable = db.collection('uni-id-users')export const useUserStore = defineStore("user",()=>{let hostUserInfo = uni.getStorageSync('uni-id-pages-userInfo')||{}const userInfo = ref(hostUserInfo);const hasLogin= ref(Object.keys(hostUserInfo).length != 0);// data不为空，表示传递要更新的值(注意不是覆盖是合并),什么也不传时，直接查库获取更新async function updateUserInfo(data = false) {if (data) {usersTable.where('_id==$env.uid').update(data).then(e => {// console.log(e);if (e.result.updated) {uni.showToast({title: "更新成功",icon: 'none',duration: 3000});setUserInfo(data)} else {uni.showToast({title: "没有改变",icon: 'none',duration: 3000});}})} else {const uniIdCo = uniCloud.importObject("uni-id-co", {customUI: true})try {let res = await usersTable.where("'_id' == $cloudEnv_uid").field('mobile,nickname,username,email,avatar_file').get()const realNameRes = await uniIdCo.getRealNameInfo()// console.log('fromDbData',res.result.data);setUserInfo({...res.result.data[0],realNameAuth: realNameRes})} catch (e) {setUserInfo({},{cover:true})console.error(e.message, e.errCode);}}}async function setUserInfo(data, {cover}={cover:false}) {// console.log('set-userInfo', data);let _userInfo = cover?data:Object.assign(userInfo.value,data)userInfo.value = Object.assign({},_userInfo)hasLogin.value = Object.keys(userInfo.value).length != 0// console.log('store.userInfo', store.userInfo);uni.setStorageSync('uni-id-pages-userInfo', userInfo.value)return data}async function logout() {// 1. 已经过期就不需要调用服务端的注销接口	2.即使调用注销接口失败，不能阻塞客户端if(uniCloud.getCurrentUserInfo().tokenExpired > Date.now()){try{await uniIdCo.logout()}catch(e){console.error(e);}}uni.removeStorageSync('uni_id_token');uni.setStorageSync('uni_id_token_expired', 0)		uni.$emit('uni-id-pages-logout')setUserInfo({},{cover:true})}//登录后的操作function loginSuccess(e = {}){const {showToast = true, toastText = '登录成功', autoBack = true, uniIdRedirectUrl = '', passwordConfirmed} = e// console.log({toastText,autoBack});if (showToast) {uni.showToast({title: toastText,icon: 'none',duration: 3000});}updateUserInfo()	uni.$emit('uni-id-pages-login-success')	}return {userInfo,hasLogin,loginSuccess,updateUserInfo}
})

在updateUserInfo函数中修改需要的字段

具体字段可以在database文件下的uni-id-users.schema数据表中查看

我们在获取的时候可以通过如下方式对字段取别名：

字段 as 别名
