前言

大家好，我是yma16，本文分享django_vue3(vite+vue3)展示贵州省的疫情
初始化vue3-vite项目
以下是初始化 Vue3-Vite 项目的步骤：

1. 确保已安装 Node.js 和 npm。

2. 打开终端，进入要创建项目的目录，运行以下命令：

   npm init vite-app <project-name>
   

   其中，<project-name>是你的项目名称。

3. 在命令行中，选择要使用的模板。这里选择 vue-ts，即使用 TypeScript 的 Vue 模板。

4. 选择完成之后，继续输入命令：

   cd <project-name>
   npm install
   

   这将进入项目目录并安装依赖项。

5. 最后，运行以下命令启动 Vue3-Vite 项目：

   npm run dev
   

   这将启动开发服务器，可以在浏览器中访问 http://localhost:3000/ 来查看应用。

背景

2022/09贵州疫情规模比较大，可以用django和vue实现一个可视化的看板

展示

地址：
https://yongma16.xyz/fund-web/#/
地图展示地区疫情的确诊病例，卡片展示标签数据，折线图展示趋势，列表展示具体区域明细

思路

后端：python爬虫获取疫情数据，返回json给前端
前端：使用echarts展示数据

后端

框架：django requests
抓取数据来源：
腾讯数据

关键实现

    data={
        'data':[],

        'msg':'request method not allowed!'
    }
    if request.method == 'GET':
        data={}
        msg='success'
        try:
            data=getOutBreak()
        except Exception as e:
            msg=str(e)
        return JsonResponse({

            'msg':msg,
            'code':1
        })
    return JsonResponse(data)

        }
        res = requests.get(url, headers=headers)
        jsonData = res.json()
        data=jsonData['data']
        jsonRes=jsonDetail(data,'day')
        if jsonRes is False:
