### 今日目标 ###

1.  完成商品添加
2.  完成订单列表
3.  完成数据统计展示

### 1.添加商品 ###

#### A.完成图片上传 ####

使用upload组件完成图片上传  
在element.js中引入upload组件，并注册  
因为upload组件进行图片上传的时候并不是使用axios发送请求  
所以，我们需要手动为上传图片的请求添加token，即为upload组件添加headers属性

//在页面中添加upload组件，并设置对应的事件和属性
    <el-tab-pane label="商品图片" name="3">
      
      <el-upload :action="uploadURL" :on-preview="handlePreview" :on-remove="handleRemove" :on-success="handleSuccess" list-type="picture" :headers="headerObj">
        <el-button size="small" type="primary">点击上传</el-button>
      </el-upload>
    </el-tab-pane>
    //在el-card卡片视图下面添加对话框用来预览图片
    
    <el-dialog title="图片预览" :visible.sync="previewVisible" width="50%">
      <img :src="previewPath" class="previewImg" />
    </el-dialog>
    
    //在data中添加数据
    data(){ 
      return { 
        ......
        //添加商品的表单数据对象
        addForm: { 
          goods_name: '',
          goods_price: 0,
          goods_weight: 0,
          goods_number: 0,
          goods_cat: [],
          //上传图片数组
          pics: []
        },
        //上传图片的url地址
        uploadURL: 'http://127.0.0.1:8888/api/private/v1/upload',
        //图片上传组件的headers请求头对象
        headerObj: {  Authorization: window.sessionStorage.getItem('token') },
        //保存预览图片的url地址
        previewPath: '',
        //控制预览图片对话框的显示和隐藏
        previewVisible:false
      }
    },
    //在methods中添加事件处理函数
    methods:{ 
      .......
      handlePreview(file) { 
        //当用户点击图片进行预览时执行，处理图片预览
        //形参file就是用户预览的那个文件
        this.previewPath = file.response.data.url
        //显示预览图片对话框
        this.previewVisible = true
      },
      handleRemove(file) { 
        //当用户点击X号删除时执行
        //形参file就是用户点击删除的文件
        //获取用户点击删除的那个图片的临时路径
        const filePath = file.response.data.tmp_path
        //使用findIndex来查找符合条件的索引
        const index = this.addForm.pics.findIndex(item => item.pic === filePath)
        //移除索引对应的图片
        this.addForm.pics.splice(index, 1)
      },
      handleSuccess(response) { 
        //当上传成功时触发执行
        //形参response就是上传成功之后服务器返回的结果
        //将服务器返回的临时路径保存到addForm表单的pics数组中
        this.addForm.pics.push({  pic: response.data.tmp_path })
      }
    }

#### B.使用富文本插件 ####

想要使用富文本插件vue-quill-editor，就必须先从依赖安装该插件  
引入并注册vue-quill-editor，打开main.js，编写如下代码

//导入vue-quill-editor（富文本编辑器）
    import VueQuillEditor from 'vue-quill-editor'
    //导入vue-quill-editor的样式
    import 'quill/dist/quill.core.css'
    import 'quill/dist/quill.snow.css'
    import 'quill/dist/quill.bubble.css'
    ......
    //全局注册组件
    Vue.component('tree-table', TreeTable)
    //全局注册富文本组件
    Vue.use(VueQuillEditor)

使用富文本插件vue-quill-editor

<el-tab-pane label="商品内容" name="4">
      
      <quill-editor v-model="addForm.goods_introduce"></quill-editor>
      
      <el-button type="primary" class="btnAdd">添加商品</el-button>
    </el-tab-pane>
    
    //在数据中添加goods_introduce
    //添加商品的表单数据对象
    addForm: { 
      goods_name: '',
      goods_price: 0,
      goods_weight: 0,
      goods_number: 0,
      goods_cat: [],
      //上传图片数组
      pics: [],
      //商品的详情介绍
      goods_introduce:''
    }
    //在global.css样式中添加富文本编辑器的最小高度
    .ql-editor{ 
        min-height: 300px;
    }
    //给添加商品按钮添加间距
    .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，为了避免goods\_cat数组转换字符串之后导致级联选择器报错  
我们需要打开vue控制条，点击依赖，安装lodash，把addForm进行深拷贝

//打开Add.vue，导入lodash
    <script>
    //官方推荐将lodash导入为_
    import _ from 'lodash'
    
    //给添加商品按钮绑定点击事件
    
    <el-button type="primary" class="btnAdd" @click="add">添加商品</el-button>
    //编写点击事件完成商品添加
    add(){ 
      this.$refs.addFormRef.validate(async valid=>{ 
        if(!valid) return this.$message.error("请填写必要的表单项!")
    
        //将addForm进行深拷贝，避免goods_cat数组转换字符串之后导致级联选择器报错
        const form = _.cloneDeep(this.addForm)
        //将goods_cat从数组转换为"1,2,3"字符串形式
        form.goods_cat = form.goods_cat.join(",")
        //处理attrs数组，数组中需要包含商品的动态参数和静态属性
        //将manyTableData（动态参数）处理添加到attrs
        this.manyTableData.forEach(item=>{ 
          form.attrs.push({  attr_id:item.attr_id, attr_value:item.attr_vals.join(" ") }) 
        })
        //将onlyTableData（静态属性）处理添加到attrs
        this.onlyTableData.forEach(item=>{ 
          form.attrs.push({  attr_id:item.attr_id, attr_value:item.attr_vals }) 
        })
    
        //发送请求完成商品的添加,商品名称必须是唯一的
        const { data:res} = await this.$http.post('goods',form)
        if(res.meta.status !== 201){ 
          return this.$message.error('添加商品失败')
        }
        this.$message.success('添加商品成功')
        //编程式导航跳转到商品列表
        this.$router.push('/goods')
      })
    }
    </script>

#### D.推送代码 ####

推送goods\_list分支到码云  
将代码添加到暂存区： git add .  
将代码提交到本地仓库： git commit -m “完成商品功能开发”  
将代码推送到码云： git push  
切换到master主分支： git checkout master  
将goods\_list分支代码合并到master: git merge goods\_list  
将master推送到码云： git push

### 2.订单列表 ###

#### A.创建分支 ####

创建order子分支并推送到码云  
创建order子分支: git checkout -b order  
将order分支推送到码云： git push -u origin order

#### B.创建路由 ####

创建订单列表路由组件并添加路由规则

//在components中新建order文件夹，新建Order.vue组件，组件中添加代码如下
    <template>
        <div>
            <h3>订单列表</h3>
            
            <el-breadcrumb separator="/">
                <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
                <el-breadcrumb-item>订单管理</el-breadcrumb-item>
                <el-breadcrumb-item>订单列表</el-breadcrumb-item>
            </el-breadcrumb>
            
            <el-card>
                
                <el-row :gutter="20">
                    <el-col :span="8">
                        <el-input placeholder="请输入内容" 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 { 
            //查询条件
            queryInfo:{ 
                query:'',
                pagenum:1,
                pagesize:10
            }
        }
      },
      created() { 
          
      },
      methods: { 
          
      }
    }
    </script>
    
    <style lang="less" scoped>
    
    </style>
    
    //打开router.js导入Order.vue并添加规则
    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.实现数据展示及分页 ####

<el-card>
        
        <el-row :gutter="20">
            <el-col :span="8">
                <el-input placeholder="请输入内容" v-model="queryInfo.query" clearable>
                    <el-button slot="append" icon="el-icon-search"></el-button>
                </el-input>
            </el-col>
        </el-row>
    
        
        <el-table :data="orderList" border stripe>
            <el-table-column type="index"></el-table-column>
            <el-table-column label="订单编号" prop="order_number"></el-table-column>
            <el-table-column label="订单价格" 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="是否发货" prop="is_send"></el-table-column>
            <el-table-column label="下单时间" 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>
    
        
        <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 { 
          //查询条件
          queryInfo: { 
            query: '',
            pagenum: 1,
            pagesize: 10
          },
          //订单列表数据
          orderList: [],
          //数据总条数
          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('获取订单列表数据失败!')
          }
    
          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.制作省市区县联动 ####

打开今天的资料，找到素材文件夹，复制citydata.js文件到components/order文件夹中  
然后导入citydata.js文件

具体代码如下：

//给修改地址按钮添加点击事件
    <el-button size="mini" type="primary" icon="el-icon-edit" @click="showEditAddress"></el-button>
    //添加修改地址对话框,在卡片视图下方添加
    
    <el-dialog title="修改收货地址" :visible.sync="addressVisible" width="50%" @close="addressDialogClosed">
        
        <el-form :model="addressForm" :rules="addressFormRules" ref="addressFormRef" label-width="100px">
            <el-form-item label="省市区县" prop="address1">
                <el-cascader :options="cityData" v-model="addressForm.address1"></el-cascader>
            </el-form-item>
            <el-form-item label="详细地址" 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">确 定</el-button>
        </span>
    </el-dialog>
    
    //js部分的代码
    <script>
    import cityData from "./citydata.js"
    export default { 
      data() { 
        return { 
          ......
          //控制修改地址对话框的显示和隐藏
          addressVisible:false,
          //修改收货地址的表单
          addressForm:{ 
              address1:[],
              address2:''
          },
          addressFormRules:{ 
              address1:[{  required: true, message: '请选择省市区县', trigger: 'blur' }],
              address2:[{  required: true, message: '请输入详细地址', trigger: 'blur' }],
          },
          //将导入的cityData数据保存起来
          cityData:cityData
          }
      },methods: { 
        ......
        showEditAddress() { 
          //当用户点击修改收货地址按钮时触发
          this.addressVisible = true;
        },
        addressDialogClosed(){ 
            this.$refs.addressFormRef.resetFields()
        }
      }
    }
    </script>
    <style lang="less" scoped>
    .el-cascader{ 
        width: 100%;
    }
    </style>

#### E.制作物流进度对话框 ####

因为我们使用的是element-ui中提供的Timeline组件，所以需要导入并注册组件  
打开element.js,编写代码会进行导入和注册

import { 
        Timeline,TimelineItem
    } from 'element-ui'
    
    Vue.use(Timeline)
    Vue.use(TimelineItem)

打开Order.vue文件，添加代码实现物流进度对话框

<el-dialog title="物流进度" :visible.sync="progressVisible" width="50%">
        
        <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 { 
          ......
          //控制物流进度对话框的显示和隐藏
          progressVisible: false,
          //保存物流信息
          progressInfo: []
          }
      },methods: { 
        ......
        async showProgress() { 
          //发送请求获取物流数据
          const {  data: res } = await this.$http.get('/kuaidi/804909574412544580')
    
          if (res.meta.status !== 200) { 
            return this.$message.error('获取物流进度失败!')
          }
          this.progressInfo = res.data
          //显示对话框
          this.progressVisible = true
        }
      }
    }
    </script>

#### F.推送代码 ####

将order分支代码推送至码云  
将代码添加到暂存区： git add .  
将代码提交到本地仓库： git commit -m “完成订单列表功能开发”  
将代码推送到码云： git push  
切换到master主分支： git checkout master  
将goods\_list分支代码合并到master: git merge order  
将master推送到码云： git push

### 3.数据统计 ###

#### A.创建子分支 ####

创建report子分支并推送到码云  
创建report子分支: git checkout -b report  
将report分支推送到码云： git push -u origin report

#### B.创建路由 ####

创建数据统计路由组件并添加路由规则

//在components中新建report文件夹，新建Report.vue组件，组件中添加代码如下
    <template>
        <div>
            <h3>数据报表</h3>
            
            <el-breadcrumb separator="/">
                <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>
            
            <el-card></el-card>
        </div>
    </template>
        
    <script>
    export default { 
      data() { 
        return { 
    
        }
      },created(){ 
    
      },methods:{ 
    
      }
    }
    </script>
    
    <style lang="less" scoped>
    
    </style>

打开router.js，导入Report.vue并设置路由规则

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: "/roles", component: Roles  },
      {  path: "/categories", component: Cate  },
      {  path: "/params", component: Params  },
      {  path: "/goods", component: GoodList  },
      {  path: "/goods/add", component: GoodAdd  },
      {  path: "/orders", component: Order  },
      {  path: "/reports", component: Report  }
    ]

#### C.导入ECharts并使用 ####

<template>
        <div>
            <h3>数据报表</h3>
            
            <el-breadcrumb separator="/">
                <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
