vue3后台管理系统之登录界面和业务的实现

1.静态页面的搭建

<template><div class="login_container"><el-row><el-col :span="12" :xs="0" /><el-col :span="12" :xs="24"><!-- 登录的表单 --><el-form ref="loginForms" class="login_form" :model="loginForm" :rules="rules"><h1>Hello</h1><h2>欢迎来到xxx管理系统</h2><el-form-item prop="username"><el-input v-model="loginForm.username" :prefix-icon="User" /></el-form-item><el-form-item prop="password"><el-input v-model="loginForm.password" type="password" :prefix-icon="Lock" show-password /></el-form-item><el-form-item><el-button :loading="loading" class="login_btn" type="primary" size="default" @click="login">登录</el-button></el-form-item></el-form></el-col></el-row></div>
</template><script setup lang="ts">
import { Lock, User } from '@element-plus/icons-vue'
import { reactive, ref } from 'vue'
//引入用户相关的小仓库
// import useUserStore from '@/store/moudules/user'
// const useStore = useUserStore()
//获取el-form组件
const loginForms = ref()
//获取路由器//定义变量控制按钮加载效果
const loading = ref(false)
//收集账号与密码的数据
const loginForm = reactive({ username: 'admin', password: '111111' })//自定义校验规则函数
const validatorUserName = (value: any, callback: any) => {//rule:即为校验规则对象//value:即为表单元素文本内容//函数:如果符合条件callBack放行通过即为//如果不符合条件callBack方法,注入错误提示信息if (value.length >= 5) {callback()} else {callback(new Error('账号长度至少五位'))}
}const validatorPassword = (value: any, callback: any) => {if (value.length >= 6) {callback()} else {callback(new Error('密码长度至少六位'))}
}//定义表单校验需要配置对象
const rules = {//规则对象属性://required,代表这个字段务必要校验的//min:文本长度至少多少位//max:文本长度最多多少位//message:错误的提示信息//trigger:触发校验表单的时机 change->文本发生变化触发校验,blur:失去焦点的时候触发校验规则username: [// { required: true, min: 6, max: 10, message: '账号长度至少六位', trigger: 'change' }{ trigger: 'change', validator: validatorUserName }],password: [// { required: true, min: 6, max: 15, message: '密码长度至少6位', trigger: 'change' }{ trigger: 'change', validator: validatorPassword }]
}//登录请求
const login = () => {console.log(111)// useStore.userLogin(loginForm)
}
</script><style scoped lang="scss">
.login_container {width: 100%;height: 100vh;background: url('@/assets/images/background.jpg') no-repeat;background-size: cover;.login_form {position: relative;width: 80%;top: 30vh;background: url('@/assets/images/login_form.png') no-repeat;background-size: cover;padding: 40px;h1 {color: white;font-size: 40px;}h2 {font-size: 20px;color: white;margin: 20px 0px;}.login_btn {width: 100%;}}
}
</style>

2.登录业务逻辑处理

// 创建用户仓库
import { defineStore } from 'pinia'
// 引入接口
import { reqLogin } from '@/api/user'
// u引入数据类型
import type { loginForm, loginResponseData } from '@/api/user/type'
import type { UserState } from './types/type'
// 引入操作本地存储
import { SET_TOKEN, GET_TOKEN } from '@/utils/token'
const useUserStore = defineStore('User', {// 小仓库存储数据state: (): UserState => {return {token: GET_TOKEN(),}},// 异步逻辑actions: {async userLogin(data: loginForm) {// 登录请求const res: loginResponseData = await reqLogin(data)console.log(res)if (res.code === 200) {this.token = res.data.token as stringSET_TOKEN(res.data.token as string)return 'ok'} else {return Promise.reject(new Error(res.data.message))}},},getters: {},
})
export default useUserStore

定义token数据类型

修改登录返回结果数据类型

封装本地存储数据和读取数据的方法

完善登录界面

封装判断时间函数

//封装一个函数:获取一个结果:当前早上|上午|下午|晚上
export const getTime = () => {let message = ''//通过内置构造函数Dateconst hours = new Date().getHours()//情况的判断if (hours <= 9) {message = '早上'} else if (hours < 12) {message = '上午'} else if (hours <= 18) {message = '下午'} else {message = '晚上'}return message
}
