今天主要在学习如何用vue来连接后端springboot，并学会初步的拆分vue中的script片段为api文件来方便复用。

<script setup>
import { User, Lock } from '@element-plus/icons-vue'
import { ref } from 'vue'
//控制注册与登录表单的显示， 默认显示注册
const isRegister = ref(false)

const registerData = ref({
    username: '',
    password: '',
    rePassword: ''
})

const checkRePassword=(rule,value,callback)=>{
    if(value==='')
    {
        callback(new Error('请再次确认密码'))
    }else if(value!==registerData.value.password)
    {
        callback(new Error('请确保两次输入的密码一样'))
    }else{
        callback
    }
}
const regisRules = {
    username: [
        {
            required: true, message: '请输入用户名', trigger: 'blur' //必须输入，返回信息，校验时机
        },
        { min:5,max:16,message:'注册的用户名应在5~16位',trigger:'blur'}
    ],
    password: [
    {
            required: true, message: '请输入密码', trigger: 'blur' //必须输入，返回信息，校验时机
        },
        { min:5,max:16,message:'注册的密码应在5~16位',trigger:'blur'} 
    ],
    rePassword: [
        {
            validator:checkRePassword,trigger:'blur'
        }
    ]
}

//调用后台接口完成注册
import {userRegisterService} from '@/api/user.js'
const register= async()=>{
    let result=await userRegisterService(registerData.value);
    if(result.code===0){
        alert(result.msg?result.msg:'注册成功');
    }
    else{
        alert('注册失败');
    }
}
</script>
