搭建登录注册页面
效果
代码
Login.vue
<script setup>
import {ref} from "vue"
import {userRegisterService,userLoginService} from "@/api/user"
import { showNotify } from 'vant';
//引入路由
import {useRouter} from 'vue-router'
const router = useRouter()
//注册页为true,登录页为false
const isRegister = ref(false)
//定义注册数据模型
const registerData = ref({
userAccount: '',
userPassword: '',
checkPassword: ''
})
//清除注册数据
const clearRegisterData = ()=>{
registerData.value = {
userAccount: '',
userPassword: '',
checkPassword: ''
}
}
//验证规则
const usernamePattern = /^[a-zA-Z0-9!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]{4,15}$/;
const passwordPattern = /^[a-zA-Z0-9!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]{8,15}$/;
const validator = (val) => registerData.value.userPassword === val;
//调用后台接口完成注册
const register = async()=>{
let result = await userRegisterService(registerData.value);
showNotify({ type: 'success', message: '注册成功！' });
clearRegisterData();
isRegister.value = false
}
//调用后台接口完成登录
const login=async()=>{
let result = await userLoginService(registerData.value)
showNotify({ type: 'success', message: '登录成功！' });
// tokenStore.setToken(result.data)
// console.log(result);
// console.log(tokenStore.token);
// 跳转到首页
router.push('/')
}

开发中遇到的问题
一、动态绑定无法正常使用
问题描述： 当我想通过v-if="isRegister"，来实现登录与注册的切换，但是无法实现。isRegister是一个动态绑定的布尔值，为true显示注册页面表单，为false显示登录表单页面。
解决过程： 在《script setup> 中添上setup
具体实现：
<script setup>
</script>
二、无法设置背景
问题描述： 无法给页面设置背景
解决过程： 编写css
具体实现：
#building{
background:url("../images/law.png");
width:100%;
height:100%;
position:fixed;
background-size:100% 100%;
}
