搭建登录架构解决方案与实现

构建登录页面 UI 结构

1. 在 views 中创建 login 文件夹，之后在其中再创建 index.vue 文件
2. 在 router/index.js 中增加以下路由配置

/**
 * 路由表
 */
const publicRoutes = [
  {
    path: '/login',
    component: () => import('@/views/login/index')
  }
]

const router = createRouter({
  history: createWebHashHistory,
  routes: publicRoutes
})

3. 在 login/index.vue 中，生成基本的页面结构

<template>
  <div></div>
</template>

<script setup>
</script>

<style lang="scss" scoped>
</style>

4. 创建登录页面的基本结构

<template>
  <div class="login-container">
    <el-form class="login-form" >
      <div class="title-container">
        <h3 class="title">用户登录</h3>
      </div>
      <el-form-item prop="username">
        <span class="svg-container">
          <el-icon>
            <avatar />
          </el-icon>
        </span>
        <el-input
          placeholder="username"
          name="username"
          type="text"
        />
      </el-form-item>
      <el-form-item prop="password">
        <span class="svg-container">
          <el-icon>
            <avatar />
          </el-icon>
        </span>
        <el-input
          placeholder="password"
          name="password"
        />
        <span class="show-pwd">
          <el-icon>
            <avatar />
          </el-icon>
        </span>
      </el-form-item>
      <el-button type="primary" style="width: 100%; margin-bottom: 30px"
        >登录</el-button
      >
    </el-form>
  </div>
</template>

<script setup>
// 导入组件之后无需注册可直接使用
import { Avatar } from '@element-plus/icons'
</script>

美化登录页面

1. 在 src 文件下创建 styles/index.scss 文件

html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
  -moz-osx-font-smoothing: grayscale;
  -webkit-font-smoothing: antialiased;
  text-rendering: optimizeLegibility;
  font-family: Helvetica Neue, Helvetica, PingFang SC, Hiragino Sans GB,
    Microsoft YaHei, Arial, sans-serif;
}

#app {
  height: 100%;
}

*,
*:before,
*:after {
  box-sizing: inherit;
  margin: 0;
  padding: 0;
}

a:focus,
a:active {
  outline: none;
}

a,
a:focus,
a:hover {
  cursor: pointer;
  color: inherit;
  text-decoration: none;
}

div:focus {
  outline: none;
}

.clearfix {
  &:after {
    visibility: hidden;
    display: block;
    font-size: 0;
    content: ' ';
    clear: both;
    height: 0;
  }
}

2. 在 main.js 中导入全局样式

import './styles/index.scxx'

3. 在 views/login/index.vue 中写入样式

<style lang="scss" scoped>
$bg: #2d3a4b;
$dark_gray: #889aa4;
$light_gray: #eee;
$cursor: #fff;

.login-container {
  min-height: 100%;
  width: 100%;
  background-color: $bg;
  overflow: hidden;

  .login-form {
    position: relative;
    width: 520px;
    max-width: 100%;
    padding: 160px 35px 0;
    margin: 0 auto;
    overflow: hidden;

    ::v-deep .el-form-item {
      border: 1px solid rgba(255, 255, 255, 0.1);
      background: rgba(0, 0, 0, 0.1);
      border-radius: 5px;
      color: #454545;
    }

    ::v-deep .el-input {
      display: inline-block;
      height: 47px;
      width: 85%;

      input {
        background: transparent;
        border: 0px;
        -webkit-appearance: none;
        border-radius: 0px;
        padding: 12px 5px 12px 15px;
        color: $light_gray;
        height: 47px;
        caret-color: $cursor;
      }
    }
  }


  .svg-container {
    padding: 6px 5px 6px 15px;
    color: $dark_gray;
    vertical-align: middle;
    display: inline-block;
  }

  .title-container {
    position: relative;

    .title {
      font-size: 26px;
      color: $light_gray;
      margin: 0px auto 40px auto;
      text-align: center;
      font-weight: bold;
    }
  }

  .show-pwd {
    position: absolute;
    right: 10px;
    top: 7px;
    font-size: 16px;
    color: $dark_gray;
    cursor: pointer;
    user-select: none;
  }
}
</style>
