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 string
                SET_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Date
    const 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
}
