vue项目实战-电商后台管理系统

项目简介:

该项目为电商后台的管理系统。设计了登录页面。

管理人员需要通过输入正确的用户名和密码才能登录。登陆成功之后进入管理页面:

管理页面由五个子模块组成:用户管理,权限管理,商品管理,订单管理,数据统计;

每个子模块有若干子模块组成,用户管理下->用户列表,权限管理->角色列表,权限管理,商品管理->商品列表,分类参数,商品分配,订单管理->订单列表,数据统计->数据报表

登录页面

登录页面中对用户输入的内容进行预校验,如果不符合要求则,则不向后端发送请求,同事挂载路由守卫,防止强制跳转。同时设置令牌校验,避免重复登录。如果用户输入格式正确的用户名以及密码时,向后端发送请求,请求通过则跳转到管理页面,否则返回登录页面。

路由导航守卫:

// 挂载路由导航守卫
router.beforeEach((to, from, next) => {
  // to 将要访问的路径
  // from 代表从哪个路径跳转而来
  // next 是一个函数,表示放行
  //     next()  放行    next('/login')  强制跳转

  if (to.path === '/login') return next()
  // 获取token
  const tokenStr = window.sessionStorage.getItem('token')
  if (!tokenStr) return next('/login')
  next()
})

登录页面核心代码:

<template>
  <div class="login_container">
    <div class="login_box">
      <!-- 头像区域 -->
      <div class="avatar_box">
        <img src="../assets/logo.png" alt="">
      </div>
      <!-- 登录表单区域 -->
      <el-form ref="loginFormRef" :model="loginForm" :rules="loginFormRules" label-width="0px" class="login_form">
        <!-- 用户名 -->
        <el-form-item prop="username">
          <el-input v-model="loginForm.username" prefix-icon="iconfont icon-user"></el-input>
        </el-form-item>
        <!-- 密码 -->
        <el-form-item prop="password">
          <el-input v-model="loginForm.password" prefix-icon="iconfont icon-3702mima" type="password"></el-input>
        </el-form-item>
        <!-- 按钮区域 -->
        <el-form-item class="btns">
          <el-button type="primary" @click="login">登录</el-button>
          <el-button type="info" @click="resetLoginForm">重置</el-button>
        </el-form-item>
      </el-form>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      // 这是登录表单的数据绑定对象
      loginForm: {
        username: 'admin',
        password: '123456'
      },
      // 这是表单的验证规则对象
      loginFormRules: {
        // 验证用户名是否合法
        username: [
          { required: true, message: '请输入登录名称', trigger: 'blur' },
          { min: 3, max: 10, message: '长度在 3 到 10 个字符', trigger: 'blur' }
        ],
        // 验证密码是否合法
        password: [
          { required: true, message: '请输入登录密码', trigger: 'blur' },
          { min: 6, max: 15, message: '长度在 6 到 15 个字符', trigger: 'blur' }
        ]
      }
    }
  },
  methods: {
    // 点击重置按钮,重置登录表单
    resetLoginForm() {
      // console.log(this);
      this.$refs.loginFormRef.resetFields()
    },
    login() {
      this.$refs.loginFormRef.validate(async valid => {
        if (!valid) return
        const { data: res } = await this.$http.post('login', this.loginForm)
        if (res.meta.status !== 200) return this.$message.error('登录失败!')
        this.$message.success('登录成功')
        // 1. 将登录成功之后的 token,保存到客户端的 sessionStorage 中
        //   1.1 项目中出了登录之外的其他API接口,必须在登录之后才能访问
        //   1.2 token 只应在当前网站打开期间生效,所以将 token 保存在 sessionStorage 中
        window.sessionStorage.setItem('token', res.data.token)
        // 2. 通过编程式导航跳转到后台主页,路由地址是 /home
        this.$router.push('/home')
      })
    }
  }
}

菜单实现

管理页面有一个侧面的两级菜单,菜单的数据来自于后端,点击二级菜单会跳转到相应的子页面中。在el-menu中设置router属性,即可通过index添加到路由上进行跳转。

<template>
  <el-container class="home-container">

      <el-button type="info" @click="logout">退出</el-button>

用户管理

用户列表

用户管理下有用户列表,这里渲染了后端的用户列表,可以编辑用户信息,删除用户,为用户分配角色,还可以对用户是否禁用进行管理;除此之外,还添加了查询用户,添加用户,和分页功能。

核心代码:

<template>
  <div>
    <!-- 面包屑导航区域 -->
    <el-breadcrumb separator-class="el-icon-arrow-right">
      <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
      <el-breadcrumb-item>用户管理</el-breadcrumb-item>
      <el-breadcrumb-item>用户列表</el-breadcrumb-item>
    </el-breadcrumb>

    <!-- 卡片视图区域 -->
    <el-card>
      <!-- 搜索与添加区域 -->
      <el-row :gutter="20">
        <el-col :span="8">

            <el-button slot="append" icon="el-icon-search" @click="getUserList"></el-button>
          </el-input>
        </el-col>
        <el-col :span="4">
          <el-button type="primary" @click="addDialogVisible = true">添加用户</el-button>
        </el-col>
      </el-row>

      <!-- 用户列表区域 -->
      <el-table :data="userlist" border stripe>

数据统计

数据报表

数据统计部分用到了echarts,从后端获得数据后通过 _.merge()将数据组合在一起,最后渲染在页面上

<template>
  <div>
    <!-- 面包屑导航区域 -->
    <el-breadcrumb separator-class="el-icon-arrow-right">
      <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
      <el-breadcrumb-item>数据统计</el-breadcrumb-item>
      <el-breadcrumb-item>数据报表</el-breadcrumb-item>
    </el-breadcrumb>

    <!-- 卡片视图区域 -->
    <el-card>
      <!-- 2. 为ECharts准备一个具备大小(宽高)的Dom -->
      <div id="main" style="width: 750px;height:400px;"></div>
    </el-card>
  </div>
</template>

<script>
// 1. 导入 echarts
import echarts from 'echarts'
import _ from 'lodash'

export default {
  data() {
    return {
      // 需要合并的数据
      options: {
        title: {
          text: '用户来源'
        },
        tooltip: {
          trigger: 'axis',
          axisPointer: {
            type: 'cross',
            label: {
              backgroundColor: '#E9EEF3'
            }
          }
        },
        grid: {
          left: '3%',
          right: '4%',
          bottom: '3%',
          containLabel: true
        },
        xAxis: [
          {
            boundaryGap: false
          }
        ],
        yAxis: [
          {
            type: 'value'
          }
        ]
      }
    }
  },
  created() {},
  // 此时,页面上的元素,已经被渲染完毕了!
  async mounted() {
    // 3. 基于准备好的dom,初始化echarts实例
    var myChart = echarts.init(document.getElementById('main'))

    const { data: res } = await this.$http.get('reports/type/1')
    if (res.meta.status !== 200) {
      return this.$message.error('获取折线图数据失败!')
    }

    // 4. 准备数据和配置项
    const result = _.merge(res.data, this.options)

    // 5. 展示数据
    myChart.setOption(result)
  },
  methods: {}
}
</script>
