1.添加商品

A.完成圖片上傳

使用upload組件完成圖片上傳
在element.js中引入upload組件，并注冊
因?yàn)閡pload組件進(jìn)行圖片上傳的時候并不是使用axios發(fā)送請求
所以，我們需要手動為上傳圖片的請求添加token，即為upload組件添加headers屬性

//在頁面中添加upload組件，并設(shè)置對應(yīng)的事件和屬性
<el-tab-pane label="商品圖片" name="3">
  <!-- 商品圖片上傳
  action:指定圖片上傳api接口
  :on-preview ： 當(dāng)點(diǎn)擊圖片時會觸發(fā)該事件進(jìn)行預(yù)覽操作,處理圖片預(yù)覽
  :on-remove : 當(dāng)用戶點(diǎn)擊圖片右上角的X號時觸發(fā)執(zhí)行
  :on-success：當(dāng)用戶點(diǎn)擊上傳圖片并成功上傳時觸發(fā)
  list-type ：設(shè)置預(yù)覽圖片的方式
  :headers ：設(shè)置上傳圖片的請求頭 -->
  <el-upload :action="uploadURL" :on-preview="handlePreview" :on-remove="handleRemove" :on-success="handleSuccess" list-type="picture" :headers="headerObj">
    <el-button size="small" type="primary">點(diǎn)擊上傳</el-button>
  </el-upload>
</el-tab-pane>
//在el-card卡片視圖下面添加對話框用來預(yù)覽圖片
<!-- 預(yù)覽圖片對話框 -->
<el-dialog title="圖片預(yù)覽" :visible.sync="previewVisible" width="50%">
  <img :src="previewPath" class="previewImg" />
</el-dialog>

//在data中添加數(shù)據(jù)
data(){
  return {
    ......
    //添加商品的表單數(shù)據(jù)對象
    addForm: {
      goods_name: '',
      goods_price: 0,
      goods_weight: 0,
      goods_number: 0,
      goods_cat: [],
      //上傳圖片數(shù)組
      pics: []
    },
    //上傳圖片的url地址
    uploadURL: 'http://127.0.0.1:8888/api/private/v1/upload',
    //圖片上傳組件的headers請求頭對象
    headerObj: { Authorization: window.sessionStorage.getItem('token') },
    //保存預(yù)覽圖片的url地址
    previewPath: '',
    //控制預(yù)覽圖片對話框的顯示和隱藏
    previewVisible:false
  }
},
//在methods中添加事件處理函數(shù)
methods:{
  .......
  handlePreview(file) {
    //當(dāng)用戶點(diǎn)擊圖片進(jìn)行預(yù)覽時執(zhí)行，處理圖片預(yù)覽
    //形參file就是用戶預(yù)覽的那個文件
    this.previewPath = file.response.data.url
    //顯示預(yù)覽圖片對話框
    this.previewVisible = true
  },
  handleRemove(file) {
    //當(dāng)用戶點(diǎn)擊X號刪除時執(zhí)行
    //形參file就是用戶點(diǎn)擊刪除的文件
    //獲取用戶點(diǎn)擊刪除的那個圖片的臨時路徑
    const filePath = file.response.data.tmp_path
    //使用findIndex來查找符合條件的索引
    const index = this.addForm.pics.findIndex(item => item.pic === filePath)
    //移除索引對應(yīng)的圖片
    this.addForm.pics.splice(index, 1)
  },
  handleSuccess(response) {
    //當(dāng)上傳成功時觸發(fā)執(zhí)行
    //形參response就是上傳成功之后服務(wù)器返回的結(jié)果
    //將服務(wù)器返回的臨時路徑保存到addForm表單的pics數(shù)組中
    this.addForm.pics.push({ pic: response.data.tmp_path })
  }
}

B.使用富文本插件

依賴項(xiàng)->安裝依賴項(xiàng)->運(yùn)行依賴 ( vue-quill-editor )

想要使用富文本插件vue-quill-editor，就必須先從依賴安裝該插件
引入并注冊vue-quill-editor，打開main.js，編寫如下代碼

//導(dǎo)入vue-quill-editor（富文本編輯器）
import VueQuillEditor from 'vue-quill-editor'
//導(dǎo)入vue-quill-editor的樣式
import 'quill/dist/quill.core.css'
import 'quill/dist/quill.snow.css'
import 'quill/dist/quill.bubble.css'
......
//全局注冊組件
Vue.component('tree-table', TreeTable)
//全局注冊富文本組件
Vue.use(VueQuillEditor)

使用富文本插件vue-quill-editor

<!-- 富文本編輯器組件 -->
<el-tab-pane label="商品內(nèi)容" name="4">
  <!-- 富文本編輯器組件 -->
  <quill-editor v-model="addForm.goods_introduce"></quill-editor>
  <!-- 添加商品按鈕 -->
  <el-button type="primary" class="btnAdd">添加商品</el-button>
</el-tab-pane>

//在數(shù)據(jù)中添加goods_introduce
//添加商品的表單數(shù)據(jù)對象
addForm: {
  goods_name: '',
  goods_price: 0,
  goods_weight: 0,
  goods_number: 0,
  goods_cat: [],
  //上傳圖片數(shù)組
  pics: [],
  //商品的詳情介紹
  goods_introduce:''
}
//在global.css樣式中添加富文本編輯器的最小高度
.ql-editor{
    min-height: 300px;
}
//給添加商品按鈕添加間距
.btnAdd{
  margin-top:15px;
}

C.添加商品

完成添加商品的操作
在添加商品之前，為了避免goods_cat數(shù)組轉(zhuǎn)換字符串之后導(dǎo)致級聯(lián)選擇器報(bào)錯
我們需要打開vue控制條，點(diǎn)擊依賴，安裝lodash，把a(bǔ)ddForm進(jìn)行深拷貝

//打開Add.vue，導(dǎo)入lodash
<script>
//官方推薦將lodash導(dǎo)入為_
import _ from 'lodash'

//給添加商品按鈕綁定點(diǎn)擊事件
<!-- 添加商品按鈕 -->
<el-button type="primary" class="btnAdd" @click="add">添加商品</el-button>
//編寫點(diǎn)擊事件完成商品添加
add(){
  this.$refs.addFormRef.validate(async valid=>{
    if(!valid) return this.$message.error("請?zhí)顚懕匾谋韱雾?xiàng)!")

    //將addForm進(jìn)行深拷貝，避免goods_cat數(shù)組轉(zhuǎn)換字符串之后導(dǎo)致級聯(lián)選擇器報(bào)錯
    const form = _.cloneDeep(this.addForm)
    //將goods_cat從數(shù)組轉(zhuǎn)換為"1,2,3"字符串形式
    form.goods_cat = form.goods_cat.join(",")
    //處理attrs數(shù)組，數(shù)組中需要包含商品的動態(tài)參數(shù)和靜態(tài)屬性
    //將manyTableData（動態(tài)參數(shù)）處理添加到attrs
    this.manyTableData.forEach(item=>{
      form.attrs.push({ attr_id:item.attr_id, attr_value:item.attr_vals.join(" ") }) 
    })
    //將onlyTableData（靜態(tài)屬性）處理添加到attrs
    this.onlyTableData.forEach(item=>{
      form.attrs.push({ attr_id:item.attr_id, attr_value:item.attr_vals }) 
    })

    //發(fā)送請求完成商品的添加,商品名稱必須是唯一的
    const {data:res} = await this.$http.post('goods',form)
    if(res.meta.status !== 201){
      return this.$message.error('添加商品失敗')
    }
    this.$message.success('添加商品成功')
    //編程式導(dǎo)航跳轉(zhuǎn)到商品列表
    this.$router.push('/goods')
  })
}
</script>

D.推送代碼

推送goods_list分支到碼云
將代碼添加到暫存區(qū)： git add .
將代碼提交到本地倉庫： git commit -m "完成商品功能開發(fā)"
將代碼推送到碼云： git push
切換到master主分支： git checkout master
將goods_list分支代碼合并到master: git merge goods_list
將master推送到碼云： git push

2.訂單列表

A.創(chuàng)建分支

創(chuàng)建order子分支并推送到碼云
創(chuàng)建order子分支: git checkout -b order
將order分支推送到碼云： git push -u origin order

B.創(chuàng)建路由

創(chuàng)建訂單列表路由組件并添加路由規(guī)則

//在components中新建order文件夾，新建Order.vue組件，組件中添加代碼如下
<template>
    <div>
        <h3>訂單列表</h3>
        <!-- 面包屑導(dǎo)航 -->
        <el-breadcrumb separator="/">
            <el-breadcrumb-item :to="{ path: '/home' }">首頁</el-breadcrumb-item>
            <el-breadcrumb-item>訂單管理</el-breadcrumb-item>
            <el-breadcrumb-item>訂單列表</el-breadcrumb-item>
        </el-breadcrumb>
        <!-- 卡片視圖區(qū)域 -->
        <el-card>
            <!-- 搜索欄 -->
            <el-row :gutter="20">
                <el-col :span="8">
                    <el-input placeholder="請輸入內(nèi)容" v-model="queryInfo.query" clearable>
                        <el-button slot="append" icon="el-icon-search" ></el-button>
                    </el-input>
                </el-col>
            </el-row>
        </el-card>
    </div>
</template>

<script>
export default {
  data() {
    return {
        //查詢條件
        queryInfo:{
            query:'',
            pagenum:1,
            pagesize:10
        }
    }
  },
  created() {
      
  },
  methods: {
      
  }
}
</script>

<style lang="less" scoped>

</style>

//打開router.js導(dǎo)入Order.vue并添加規(guī)則
import Order from './components/order/Order.vue'

path: '/home', component: Home, redirect: '/welcome', children: [
  { path: "/welcome", component: Welcome },
  { path: "/users", component: Users },
  { path: "/rights", component: Rights },
  { path: "/roles", component: Roles  },
  { path: "/categories", component: Cate  },
  { path: "/params", component: Params  },
  { path: "/goods", component: GoodList  },
  { path: "/goods/add", component: GoodAdd  },
  { path: "/orders", component: Order  }
]

C.實(shí)現(xiàn)數(shù)據(jù)展示及分頁

<!-- 卡片視圖區(qū)域 -->
<el-card>
    <!-- 搜索欄 -->
    <el-row :gutter="20">
        <el-col :span="8">
            <el-input placeholder="請輸入內(nèi)容" v-model="queryInfo.query" clearable>
                <el-button slot="append" icon="el-icon-search"></el-button>
            </el-input>
        </el-col>
    </el-row>

    <!-- 訂單表格 -->
    <el-table :data="orderList" border stripe>
        <el-table-column type="index"></el-table-column>
        <el-table-column label="訂單編號" prop="order_number"></el-table-column>
        <el-table-column label="訂單價(jià)格" prop="order_price"></el-table-column>
        <el-table-column label="是否付款" prop="pay_status">
            <template slot-scope="scope">
                <el-tag type="success" v-if="scope.row.pay_status === '1'">已付款</el-tag>
                <el-tag type="danger" v-else>未付款</el-tag>
            </template>
        </el-table-column>
        <el-table-column label="是否發(fā)貨" prop="is_send"></el-table-column>
        <el-table-column label="下單時間" prop="create_time">
            <template slot-scope="scope">
                {{scope.row.create_time | dateFormat}}
            </template>
        </el-table-column>
        <el-table-column label="操作" width="125px">
            <template slot-scope="scope">
                <el-button size="mini" type="primary" icon="el-icon-edit"></el-button>
                <el-button size="mini" type="success" icon="el-icon-location"></el-button>
            </template>
        </el-table-column>
    </el-table>

    <!-- 分頁 -->
    <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="queryInfo.pagenum" :page-sizes="[3, 5, 10, 15]" :page-size="queryInfo.pagesize" layout="total, sizes, prev, pager, next, jumper" :total="total">
    </el-pagination>
</el-card>

<script>
export default {
  data() {
    return {
      //查詢條件
      queryInfo: {
        query: '',
        pagenum: 1,
        pagesize: 10
      },
      //訂單列表數(shù)據(jù)
      orderList: [],
      //數(shù)據(jù)總條數(shù)
      total: 0
    }
  },
  created() {
    this.getOrderList()
  },
  methods: {
    async getOrderList() {
      const { data: res } = await this.$http.get('orders', {
        params: this.queryInfo
      })

      if (res.meta.status !== 200) {
        return this.$message.error('獲取訂單列表數(shù)據(jù)失敗!')
      }

      this.total = res.data.total
      this.orderList = res.data.goods
    },
    handleSizeChange(newSize){
        this.queryInfo.pagesize = newSize
        this.getOrderList()
    },
    handleCurrentChange(newPage){
        this.queryInfo.pagenum = newPage
        this.getOrderList()
    }
  }
}
</script>

D.制作省市區(qū)縣聯(lián)動

打開今天的資料，找到素材文件夾，復(fù)制citydata.js文件到components/order文件夾中
然后導(dǎo)入citydata.js文件

<script>
  import cityData from "./citydata.js"
</script>

具體代碼如下：

//給修改地址按鈕添加點(diǎn)擊事件
<el-button size="mini" type="primary" icon="el-icon-edit" @click="showEditAddress"></el-button>
//添加修改地址對話框,在卡片視圖下方添加
<!-- 修改地址對話框 -->
<el-dialog title="修改收貨地址" :visible.sync="addressVisible" width="50%" @close="addressDialogClosed">
    <!-- 添加表單 -->
    <el-form :model="addressForm" :rules="addressFormRules" ref="addressFormRef" label-width="100px">
        <el-form-item label="省市區(qū)縣" prop="address1">
            <el-cascader :options="cityData" v-model="addressForm.address1"></el-cascader>
        </el-form-item>
        <el-form-item label="詳細(xì)地址" prop="address2">
            <el-input v-model="addressForm.address2"></el-input>
        </el-form-item>
    </el-form>
    <span slot="footer" class="dialog-footer">
        <el-button @click="addressVisible = false">取 消</el-button>
        <el-button type="primary" @click="addressVisible = false">確 定</el-button>
    </span>
</el-dialog>

//js部分的代碼
<script>
import cityData from "./citydata.js"
export default {
  data() {
    return {
      ......
      //控制修改地址對話框的顯示和隱藏
      addressVisible:false,
      //修改收貨地址的表單
      addressForm:{
          address1:[],
          address2:''
      },
      addressFormRules:{
          address1:[{ required: true, message: '請選擇省市區(qū)縣', trigger: 'blur' }],
          address2:[{ required: true, message: '請輸入詳細(xì)地址', trigger: 'blur' }],
      },
      //將導(dǎo)入的cityData數(shù)據(jù)保存起來
      cityData:cityData
      }
  },methods: {
    ......
    showEditAddress() {
      //當(dāng)用戶點(diǎn)擊修改收貨地址按鈕時觸發(fā)
      this.addressVisible = true;
    },
    addressDialogClosed(){
        this.$refs.addressFormRef.resetFields()
    }
  }
}
</script>
<style lang="less" scoped>
.el-cascader{
    width: 100%;
}
</style>

E.制作物流進(jìn)度對話框

因?yàn)槲覀兪褂玫氖莈lement-ui中提供的Timeline組件，所以需要導(dǎo)入并注冊組件
打開element.js,編寫代碼會進(jìn)行導(dǎo)入和注冊

import {
    Timeline,TimelineItem
} from 'element-ui'

Vue.use(Timeline)
Vue.use(TimelineItem)

打開Order.vue文件，添加代碼實(shí)現(xiàn)物流進(jìn)度對話框

<!-- 物流信息進(jìn)度對話框 -->
<el-dialog title="物流進(jìn)度" :visible.sync="progressVisible" width="50%">
    <!-- 時間線組件  -->
    <el-timeline>
        <el-timeline-item v-for="(activity, index) in progressInfo" 
        :key="index" :timestamp="activity.time">
            {{activity.context}}
        </el-timeline-item>
    </el-timeline>
</el-dialog>

<script>
import cityData from './citydata.js'
export default {
  data() {
    return {
      ......
      //控制物流進(jìn)度對話框的顯示和隱藏
      progressVisible: false,
      //保存物流信息
      progressInfo: []
      }
  },methods: {
    ......
    async showProgress() {
      //發(fā)送請求獲取物流數(shù)據(jù)
      const { data: res } = await this.$http.get('/kuaidi/804909574412544580')

      if (res.meta.status !== 200) {
        return this.$message.error('獲取物流進(jìn)度失敗!')
      }
      this.progressInfo = res.data
      //顯示對話框
      this.progressVisible = true
    }
  }
}
</script>

F.推送代碼

將order分支代碼推送至碼云
將代碼添加到暫存區(qū)： git add .
將代碼提交到本地倉庫： git commit -m "完成訂單列表功能開發(fā)"
將代碼推送到碼云： git push
切換到master主分支： git checkout master

A.創(chuàng)建子分支

創(chuàng)建report子分支并推送到碼云
創(chuàng)建report子分支: git checkout -b report
將report分支推送到碼云： git push -u origin report

B.創(chuàng)建路由

創(chuàng)建數(shù)據(jù)統(tǒng)計(jì)路由組件并添加路由規(guī)則

//在components中新建report文件夾，新建Report.vue組件，組件中添加代碼如下
<template>
    <div>
        <h3>數(shù)據(jù)報(bào)表</h3>
        <!-- 面包屑導(dǎo)航 -->
        <el-breadcrumb separator="/">
            <el-breadcrumb-item :to="{ path: '/home' }">首頁</el-breadcrumb-item>
            <el-breadcrumb-item>數(shù)據(jù)統(tǒng)計(jì)</el-breadcrumb-item>
            <el-breadcrumb-item>數(shù)據(jù)報(bào)表</el-breadcrumb-item>
        </el-breadcrumb>
        <!-- 卡片視圖區(qū)域 -->
        <el-card></el-card>
    </div>
</template>
    
<script>
export default {
  data() {
    return {

    }
  },created(){

  },methods:{

  }
}
</script>

<style lang="less" scoped>

</style>

打開router.js，導(dǎo)入Report.vue并設(shè)置路由規(guī)則

import Report from './components/report/Report.vue'
path: '/home', component: Home, redirect: '/welcome', children: [
  { path: "/welcome", component: Welcome },
  { path: "/users", component: Users },
  { path: "/rights", component: Rights },

  { path: "/reports", component: Report  }
]

C.導(dǎo)入ECharts并使用

<template>
    <div>
        <h3>數(shù)據(jù)報(bào)表</h3>
        <!-- 面包屑導(dǎo)航 -->
        <el-breadcrumb separator="/">
            <el-breadcrumb-item :to="{ path: '/home' }">首頁</el-breadcrumb-item>
