1、 效果图

2、创建项目

2.1 创建小程序端

2.1.1 先创建纯净项目

2.1.2 删除components

2.1.4 删除app.json红色部分

2.1.5 删除index.json红色部分

2.1.6 删除index.wxss全部内容

      }
    ]
  },
  "sitemapLocation": "sitemap.json"

}

2.1.11 删除app.wxss全部内容

2.1.12 不校验http

2.2 创建小程序后端项目

django+ drf +mysql

2.2.1 创建项目

2.2.2 安装配置mysql数据库

 pip install pymysql

项目__init__.py添加

import pymysql
pymysql.install_as_MySQLdb()

修改为mysql数据库，这时候去把mysql数据库创建好，与下面name匹配的数据库

DATABASES = {
            'default': {
            'ENGINE': 'django.db.backends.mysql',#数据库的类型
            'NAME': '33', #所使用的的数据库的名字
            'USER': 'root', #数据库服务器的用户
            'PASSWORD': '33#33', #密码
            'HOST': '192.168.1.13', #主机
            'PORT': '3306', #端口
            }
}

2.2.3 settings配置修改（国际化修改）

LANGUAGE_CODE = 'zh-hans'

TIME_ZONE = 'Asia/Shanghai'


USE_TZ = False

'rest_framework', 'django_filters',

2.2.4 运行后端

python manage.py runserver 0.0.0.0:8000

2.2.5 后期涉及需要安装的库

# 上传图片
pip install pillow

# django后台页面美化  simpleui
pip install django-simpleui -i https://pypi.tuna.tsinghua.edu.cn/simple


# rest_framework
pip install djangorestframework


# baidu人脸识别
pip install baidu-aip

3、小程序中集成的vant-app

使用谷歌浏览器打开

https://vant-ui.github.io/vant-weapp/#/home

3.1 node介绍

安装node（略）

npm install -g cnpm --registry=https://registry.npm.taobao.org

#上面地址不行了，然后注意这个要使用管理员身份打开cmd
npm install -g cnpm --registry=https://registry.npmmirror.com

npm init -y

#npm i @vant/weapp -S  # 慢

# 这个快
cnpm i @vant/weapp -S

（第6步 在之前步骤已经删除）

修改之前

修改之后

"packNpmManually": true,
    "packNpmRelationList": [
      {
        "packageJsonPath": "./package.json",
        "miniprogramNpmDistDir": "./"
      }
    ]

3.2 使用vant样式引用（这里是示例，代码不需要）

需要什么样式就引入，参照官网

  "usingComponents": {
    "van-cell": "@vant/weapp/cell/index",
    "van-cell-group":"@vant/weapp/cell-group/index",
    "van-calendar":"@vant/weapp/calendar/index",
    "van-notice-bar":"@vant/weapp/notice-bar/index",
     "van-grid": "@vant/weapp/grid/index",
    "van-grid-item": "@vant/weapp/grid-item/index"
  },

4、欢迎页面

app.json新增welcome 放第一位，作为首页

  "pages": [
    "pages/welcome/welcome",
    "pages/index/index",
    "pages/my/my",
    "pages/activity/activity",
    "pages/notice/notice"   
  ],

4.1 纯静态

4.1.1 welcome. wxml

<view class="container">
  <text class="jump" bindtap="doJump">跳过{{second}}秒</text>
  <image class="img" src="/static/images/bg/splash.png" />
</view>

4.1.2 welcome.wxss

page{
  height: 100%;
}

.container{
  width: 100%;
  height: 100%;
}
.container .img{
  width: 100%;
  height: 100%;
}
.jump{
  font-size: 30rpx;
  position: absolute;
  left: 600rpx;
  top: 80rpx;
  background-color: #dddddd;
  padding: 10rpx 20rpx;
  border-radius: 20rpx;
}

4.1.3 welcome.js

主要实现前端广告默认3秒倒计时自动跳转到首页

// pages/welcome/welcome.js
Page({

  /**
   * 页面的初始数据
   */
  data: {
    second: 3

  },
  doJump(){
    // 点击跳转到首页
    wx.switchTab({
      url: '/pages/index/index',
    })
  },

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad(options) {
    // 启动广告的定时器，倒计时
    // 清除定时器
    var instance = setInterval(() =>{
      if(this.data.second<=0) {
        // 清除定时器
        clearInterval(instance)
        // 跳转到index页面
        this.doJump()
      }
      else{
        this.setData({
          second: this.data.second-1
        })
      }
      
    },1000)
  },

  /**
   * 生命周期函数--监听页面初次渲染完成
   */
  onReady() {

  },

  /**
   * 生命周期函数--监听页面显示
   */
  onShow() {

  },

  /**
   * 生命周期函数--监听页面隐藏
   */
  onHide() {

  },

  /**
   * 生命周期函数--监听页面卸载
   */
  onUnload() {

  },

  /**
   * 页面相关事件处理函数--监听用户下拉动作
   */
  onPullDownRefresh() {

  },

  /**
   * 页面上拉触底事件的处理函数
   */
  onReachBottom() {

  },

  /**
   * 用户点击右上角分享
   */
  onShareAppMessage() {

  }
})

4.2 后端加载欢迎页

4.2.1 创建表模型

models

from django.db import models


# 开启app广页业模型表
class Welcome(models.Model):
    # upload_to 图片上传后，放到media文件夹下的welcome文件夹下
    # 必须安装pillo库 pip install pillow
    img = models.ImageField(upload_to='welcome', default='/welcome/splash.png', verbose_name="图片")
    order = models.IntegerField(verbose_name="排序")
    # 这个字段不用穿，自动生成时间
    created_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")
    is_delete = models.BooleanField(default=False, verbose_name="是否删除")
    # 如果表已存在且你不想Django管理它（如迁移），可以设置managed=False

    class Meta:
        managed = True
        db_table = 'welcome'
        verbose_name_plural = '欢迎表'

将数据迁移到mysql数据库

执行命令

# 默认所有修改过的model层转为迁移文件
makemigrations

# 默认将所有的迁移文件都执行,更新数据库
migrate

小知识：上你我使用的是第2种方法

4.2.2 开启media访问

django根目录下创建media文件夹（存储上传的图片），然后在settings设置

我使用的是这个，我认为一样

MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR / 'media'

在django项目当中进行如下设置

下面是我的设置，有一些差别

from django.contrib import admin
from django.urls import path, re_path
from django.views.static import serve
from django.conf import settings

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path(r'^media/(?P<path>.*)$', serve, {
        'document_root': settings.MEDIA_ROOT,
    }),
]

4.2.3 使用admin上传图片

4.2.3.1 配置
# 输入命令
createsuperuser


# 创建用户root
root

# 邮箱
market@163.com

#密码
123456

# 再次输入密码
123456

# 提示密码不安全，输入Y
y

from django.contrib import admin
from .models import Welcome

# Register your models here.
admin.site.register(Welcome)

http://127.0.0.1:8000/admin/login/?next=/admin

美化上面的django管理页面

# simpleui
https://github.com/newpanjing/simpleui

# simpleui文档
https://newpanjing.github.io/simpleui_docs/

# 快速上手
https://newpanjing.github.io/simpleui_docs/config.html

安装库（略，前面安装了），再settings注册simpleui

INSTALLED_APPS = [
    'simpleui',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'smart.apps.SmartConfig',
]

apps.py 新增下图

from django.apps import AppConfig


class SmartConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'smart'
    verbose_name = "首页欢迎"
4.2.3.2 上传图片

输入地址验证

http://127.0.0.1:8000/media/welcome/splash.png

4.2.4 写视图函数（后期使用cbv改造）

views

from django.shortcuts import render
from .models import Welcome
from django.http import JsonResponse
# Create your views here.


def welcome(request):
    # 查询order最大的一张图片
    result = Welcome.objects.all().order_by('-order').first()
    img = 'http://127.0.0.1:8000/media/'+str(result.img)
    return JsonResponse({'code': 100, 'msg': '成功', 'result': img})

项目路由urls

from django.contrib import admin
from django.urls import path, re_path,include
from django.views.static import serve
from django.conf import settings

urlpatterns = [
    path('admin/', admin.site.urls),
    path('smart/', include('smart.urls')),
    re_path(r'^media/(?P<path>.*)$', serve, {
        'document_root': settings.MEDIA_ROOT,
    }),
]

在smart下新建urls 应用路由

from django.contrib import admin
from django.urls import path
from .views import welcome

urlpatterns = [
    # http://127.0.0.1:8000/smart/welcome/   --> 就能获得突破数据
    path('welcome/', welcome),
]

输入地址验证（没有使用postman接口调用，偷懒）

http://127.0.0.1:8000/smart/welcome/

4.3 小程序端改造（动态获取广告）

4.3.1 welcome. wxml

img做成变量获取

<view class="container">
  <text class="jump" bindtap="doJump">跳过{{second}}秒</text>
  <image class="img" src="{{img}}" />
</view>

4.3.2 welcome. wxss

加载页面的时候调用后端接口

// pages/welcome/welcome.js
Page({

  /**
   * 页面的初始数据
   */
  data: {
    second: 3,
    img: '/static/images/bg/splash.png'

  },
  doJump(){
    // 点击跳转到首页
    wx.switchTab({
      url: '/pages/index/index',
    })
  },

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad(options) {
    // 向后端发送请求--》 获取广告页 --》 赋值给img
  wx.request({
    url: 'http://127.0.0.1:8000/smart/welcome/',
    method: "GET",

5.3 首页轮播图和公告接口

5.3.1 models

新增两张表，迁移不再累述

from django.db import models


# 开启app广页业模型表
class Welcome(models.Model):
    # upload_to 图片上传后，放到media文件夹下的welcome文件夹下
    # 必须安装pillo库 pip install pillow
    img = models.ImageField(upload_to='welcome', default='/welcome/splash.png', verbose_name="图片")
    order = models.IntegerField(verbose_name="排序")
    # 这个字段不用穿，自动生成时间
    created_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")
    is_delete = models.BooleanField(default=False, verbose_name="是否删除")
    # 如果表已存在且你不想Django管理它（如迁移），可以设置managed=False

    class Meta:
        managed = True
        db_table = 'welcome'
        verbose_name_plural = '欢迎表'
    def __str__(self):
        return str(self.img)

# 轮播图模型表
class Banner(models.Model):
    img = models.ImageField(upload_to='banner', default='/banner/banner.png', verbose_name="图片")
    order = models.IntegerField(verbose_name="排序")
    # 这个字段不用传，自动生成时间
    created_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")
    is_delete = models.BooleanField(default=False, verbose_name="是否删除")
    # 如果表已存在且你不想Django管理它（如迁移），可以设置managed=False
    class Meta:
        managed = True
        db_table = 'banner'
        verbose_name_plural = '轮播图表'

    def __str__(self):
        return str(self.img)


# 通知表
class Notice(models.Model):
    title = models.CharField(max_length=64, verbose_name="公告标题")
    content = models.TextField(verbose_name="公告内容")
    img = models.ImageField(upload_to='notice', default='/notice/notice.png', verbose_name="公告图片")
    created_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")
    is_delete = models.BooleanField(default=False, verbose_name="是否删除")

    class Meta:
        managed = True
        db_table = 'notice'
        verbose_name_plural = '通知公告表'

    def __str__(self):
        return self.title

5.3.2 admin.py注册好新表和创建文件目录

from django.contrib import admin

router = SimpleRouter()
router.register('banner', BannerViewSet, basename='banners')
urlpatterns = [
    # http://127.0.0.1:8000/smart/welcome/   --> 就能获得突破数据
    path('welcome/', welcome),
]
urlpatterns += router.urls
5.3.4.4 settings项目当中注册rest_framework

6.2 信息采集后端接口

6.2.1 新建model.py创建表

新建采集表collection、区域表area与用户userinfo表，迁移不再累述

from django.db import models


# 开启app广页业模型表
class Welcome(models.Model):
    # upload_to 图片上传后，放到media文件夹下的welcome文件夹下
    # 必须安装pillo库 pip install pillow
    img = models.ImageField(upload_to='welcome', default='/welcome/splash.png', verbose_name="图片")
    order = models.IntegerField(verbose_name="排序")
    # 这个字段不用穿，自动生成时间
    created_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")
    is_delete = models.BooleanField(default=False, verbose_name="是否删除")
    # 如果表已存在且你不想Django管理它（如迁移），可以设置managed=False

    class Meta:
        managed = True
        db_table = 'welcome'
        verbose_name_plural = '欢迎表'
    def __str__(self):
        return str(self.img)

# 轮播图模型表
class Banner(models.Model):
    img = models.ImageField(upload_to='banner', default='/banner/banner.png', verbose_name="图片")
    order = models.IntegerField(verbose_name="排序")
    # 这个字段不用传，自动生成时间
    create_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")
    is_delete = models.BooleanField(default=False, verbose_name="是否删除")
    # 如果表已存在且你不想Django管理它（如迁移），可以设置managed=False
    class Meta:
        managed = True
        db_table = 'banner'
        verbose_name_plural = '轮播图表'

    def __str__(self):
        return str(self.img)


# 通知表
class Notice(models.Model):
    title = models.CharField(max_length=64, verbose_name="公告标题")
    content = models.TextField(verbose_name="公告内容")
    img = models.ImageField(upload_to='notice', default='/notice/notice.png', verbose_name="公告图片")
    create_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")
    is_delete = models.BooleanField(default=False, verbose_name="是否删除")

    class Meta:
        managed = True
        db_table = 'notice'
        verbose_name_plural = '通知公告表'

    def __str__(self):
        return self.title


##采集表
class Collection(models.Model):
    name = models.CharField(max_length=32, verbose_name="采集人员名称")
    # 姓名拼音作为后期人脸识别的ID号
    name_pinyin = models.CharField(max_length=32, verbose_name="采集人员姓名拼音")
    avatar = models.ImageField(upload_to='collection/%Y/%m/%d/', default='/collection/default.png', verbose_name="头像")
    create_time = models.DateTimeField(auto_now=True, verbose_name="采集时间")
    # face_token  后期使用 人脸识别token唯一码
    area = models.ForeignKey(to='Area', null=True, verbose_name="网格区域", on_delete=models.CASCADE)


    class Meta:
        managed = True
        db_table = 'collection'
        verbose_name_plural = '采集表'

    def __str__(self):
        return self.name


##  区域表
class Area(models.Model):
    name = models.CharField(max_length=32, verbose_name="网格区域员")
    desc = models.CharField(max_length=32, verbose_name="网格简称")
    # 跟用户是一对多的关系  一个网格员可以采集多个网格
    user = models.ForeignKey(to='UserInfo', null=True, verbose_name="负责用户", on_delete=models.CASCADE)
    create_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")


    class Meta:
        managed = True
        db_table = 'area'
        verbose_name_plural = '区域表'

    def __str__(self):
        return self.name



### 用户表
class UserInfo(models.Model):
    username = models.CharField(max_length=32, verbose_name="用户名")
    password = models.CharField(max_length=100, verbose_name="密码")
    avatar = models.ImageField(upload_to='avatar', default='/avatar/avatar.png', verbose_name="头像")
    phone = models.CharField(max_length=111, verbose_name="手机号")
    email = models.EmailField(null=True, blank=True, verbose_name="邮箱")
    score = models.IntegerField(default=0, verbose_name="积分")
    create_time = models.DateTimeField(auto_now=True, verbose_name="创建时间")

    class Meta:
        managed = True
        db_table = 'userinfo'
        verbose_name_plural = '用户表'

    def __str__(self):
        return self.username

6.2.2 录入数据

在admin.py注册三张表

from django.contrib import admin
from .models import Banner, Welcome, Notice, Collection, Area, UserInfo

# Register your models here.
admin.site.register(Welcome)
admin.site.register(Banner)
admin.site.register(Notice)
admin.site.register(Collection)
admin.site.register(Area)
admin.site.register(UserInfo)

用户

区域表

采集表

6.2.3 serializer.py

新增CollectionSerializer类

# -*- coding: utf-8 -*-
# @Time    : 2024/9/26 9:20
# @Author  : super
# @File    : serializer.py
# @Software: PyCharm
# @Describe:
from rest_framework import serializers
from .models import Banner, Notice, Collection


class BannerSerializer(serializers.ModelSerializer):
    class Meta:
        model = Banner
        fields = "__all__"


#  通知
class NoticeSerializer(serializers.ModelSerializer):
    class Meta:
        model = Notice
        fields = "__all__"


## 采集
class CollectionSerializer(serializers.ModelSerializer):
    class Meta:
        model = Collection
        fields = ['id', 'name', 'avatar', 'area']
        depth = 1 # area 外键关联详情拿到

6.2.4 views.py实现数据采集查询接口

from django.shortcuts import render
from .models import Welcome
from django.http import JsonResponse
from rest_framework.viewsets import GenericViewSet
from rest_framework.mixins import ListModelMixin
from .models import Banner, Notice, Collection
from .serializer import BannerSerializer, NoticeSerializer, CollectionSerializer
from rest_framework.response import Response
from datetime import datetime

# Create your views here.


# 比较low 使用fbv实现
def welcome(request):
    # 查询order最大的一张图片
    result = Welcome.objects.all().order_by('-order').first()
    img = 'http://127.0.0.1:8000/media/'+str(result.img)
    return JsonResponse({'code': 100, 'msg': '成功', 'result': img})


class BannerViewSet(GenericViewSet, ListModelMixin):
    queryset = Banner.objects.filter(is_delete=False).order_by('-order')[:3]
    serializer_class = BannerSerializer

    # 重写list方法,将通知也整合进去
    def list(self, request, *args, **kwargs):
        response = super().list(request, *args, **kwargs)
        # 获取最后一条通知
        notice = Notice.objects.filter(is_delete=False).order_by('-create_time').first()
        serializer = NoticeSerializer(instance=notice)
        return Response({'code': 100, 'msg': '成功', 'banner': response.data, 'notice': serializer.data})




# 信息采集接口  -- 查询登录用户当天采集的所有数据  ---因为还有登录实现 所以暂时先查询当天采集所有数据
class Collectionviewset(GenericViewSet, ListModelMixin):
    queryset = Collection.objects.all().filter(create_time__gte=datetime.now().date()).order_by('-create_time')
    serializer_class = CollectionSerializer
    def list(self, request, *args, **kwargs):
        response = super().list(request, *args, **kwargs)
        today_count = len(self.queryset)
        return Response({'code': 100, 'msg': '成功', 'result': response.data, 'today_count': today_count})

6.2.5 分发路由

from django.contrib import admin
from django.urls import path
from .views import welcome
from rest_framework.routers import SimpleRouter
from .views import BannerViewSet, Collectionviewset

router = SimpleRouter()
router.register('banner', BannerViewSet, 'banner')
router.register('collection', Collectionviewset, 'collection')
urlpatterns = [
    # http://127.0.0.1:8000/smart/welcome/   --> 就能获得突破数据
    path('welcome/', welcome),
]
urlpatterns += router.urls

6.2.6 验证

6.3 引入矢量图标库
