 '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 pillowimg = 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=Falseclass Meta:managed = Truedb_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 settingsurlpatterns = [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
[e-mail]#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 AppConfigclass 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 settingsurlpatterns = [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 welcomeurlpatterns = [# 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imgwx.request({url: 'http://127.0.0.1:8000/smart/welcome/',method: "GET",success:(res) => {if(res.data.code == 100){console.log(res)this.setData({img: res.data.result})}else{wx.showToast({title: '网络请求异常',})}}})// 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() {}
})

5、 首页

5.1 首页静态页面

5.2.2 index.wxjs设置跳转

// index.js
Page({gotoCollection(){wx.navigateTo({url: '/pages/collection/collection',})},gotoActivity(){wx.switchTab({url: '/pages/activity/activity',})},gotoFace(){wx.navigateTo({url: '/pages/face/face',})},gotoVoice(){wx.navigateTo({url: '/pages/voice/voice',})},gotoHeart(){wx.navigateTo({url: '/pages/heart/heart',})},gotoGoods(){wx.navigateTo({url: '/pages/goods/goods',})}
})

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 pillowimg = 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=Falseclass Meta:managed = Truedb_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=Falseclass Meta:managed = Truedb_table = 'banner'verbose_name_plural = '轮播图表'def __str__(self):return str(self.img)# 通知表

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)
