1.1 用户信息需要在多个链接使用，所以需要用pinia持久化

1.1.1 定义store

import {defineStore} from 'pinia'
import {ref} from 'vue'
const useUserInfoStore = defineStore('userInfo',()=>{
    //定义状态相关的内容

    const info = ref({})

    const setInfo = (newInfo)=>{
        info.value = newInfo
    }


    const removeInfo = ()=>{
        info.value = {}
    }

    return {info,setInfo,removeInfo}

},{persist:true})

export default useUserInfoStore;

1.1.2 接口函数

import {userInfoService} from '@/api/user.js'
import useUserInfoStore from '@/stores/userInfo.js'
import {useTokenStore} from '@/stores/token.js'
const tokenStore = useTokenStore();
const userInfoStore = useUserInfoStore();
//调用函数,获取用户详细信息
const getUserInfo = async()=>{
    //调用接口
    let result = await userInfoService();
    //数据存储到pinia中
    userInfoStore.setInfo(result.data);
}

getUserInfo();

1.1.3 layout.vue中调用接口显示昵称和头像

1.2 下拉菜单

1.2.1 绑定事件

1.2.2 编写函数

//条目被点击后,调用的函数
import {useRouter} from 'vue-router'
const router = useRouter();
import {ElMessage,ElMessageBox} from 'element-plus'
const handleCommand = (command)=>{
    //判断指令
    if(command === 'logout'){
        //退出登录
        ElMessageBox.confirm(
        '您确认要退出吗?',
        '温馨提示',
        {
            confirmButtonText: '确认',
            cancelButtonText: '取消',
            type: 'warning',
        }
    )
        .then(async () => {
            //退出登录
            //1.清空pinia中存储的token以及个人信息
            tokenStore.removeToken()
            userInfoStore.removeInfo()

            //2.跳转到登录页面
            router.push('/login')
            ElMessage({
                type: 'success',
                message: '退出登录成功',
            })
            
        })
        .catch(() => {
            ElMessage({
                type: 'info',
                message: '用户取消了退出登录',
            })
        })
    }else{
        //路由
        router.push('/user/'+command)
    }
}

1.3 基本资料的修改

1.3.1 定义接口

1.3.2 页面搭建

1.3.3 数据回显

1.3.4 调用接口

<script setup>
import { ref } from 'vue'
import useUserInfoStore from '@/stores/userInfo.js'
const userInfoStore = useUserInfoStore();

const userInfo = ref({...userInfoStore.info})
const rules = {
    nickname: [
        { required: true, message: '请输入用户昵称', trigger: 'blur' },
        {
            pattern: /^\S{2,10}$/,
            message: '昵称必须是2-10位的非空字符串',
            trigger: 'blur'
        }
    ],
    email: [
        { required: true, message: '请输入用户邮箱', trigger: 'blur' },
        { type: 'email', message: '邮箱格式不正确', trigger: 'blur' }
    ]
}

//修改个人信息
import {userInfoUpdateService} from '@/api/user.js'
import {ElMessage} from 'element-plus'
const updateUserInfo = async ()=>{
    //调用接口
    let result = await userInfoUpdateService(userInfo.value);
    ElMessage.success(result.msg? result.msg : '修改成功');
    
    //修改pinia中的个人信息
    userInfoStore.setInfo(userInfo.value)
}
</script>
<template>
    <el-card class="page-container">
        <template #header>
            <div class="header">
                <span>基本资料</span>

                    </el-form-item>
                    <el-form-item label="用户昵称" prop="nickname">

                        <el-input v-model="userInfo.email"></el-input>
                    </el-form-item>
                    <el-form-item>
                        <el-button type="primary" @click="updateUserInfo">提交修改</el-button>
                    </el-form-item>
                </el-form>
            </el-col>
        </el-row>
    </el-card>
</template>
