vue项目实战--LAM系统(六)

Vue项目实战-LAM系统(六)

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">
<!-- 商品图片上传
action:指定图片上传api接口
:on-preview : 当点击图片时会触发该事件进行预览操作,处理图片预览
:on-remove : 当用户点击图片右上角的X号时触发执行
:on-success:当用户点击上传图片并成功上传时触发
list-type :设置预览图片的方式
:headers :设置上传图片的请求头 -->
<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
<!-- 预览图片对话框 -->
<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

<quill-editor v-model="addForm.goods_introduce"></quill-editor>
<!-- 添加商品按钮 -->
<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
<!-- 添加商品按钮 -->
<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

this.$refs.addressFormRef.resetFields()
}
}
}
</script>
<style lang="less" scoped>
.el-cascader{

import cityData from './citydata.js'
export default {
data() {
return {

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
