路飞学城07--课程详细页面和API接口、文件托管(七牛云)、支付宝支付
上节回顾
# 课程功能:免费课,实战课,轻课...
# 不同课程之间,字段可能不一样,差距还挺大,每个课程设计一个表
# 以实战课为例:
-课程分类表
-实战课表
-老师表
-章节表
-课时表
# 录入数据---》原生sql insert进去
# 需要写的接口
-所有课程分类接口
-查询所有课程接口
-排序
-过滤
-分页

1.1 视频播放
# 视频播放功能
第三方插件:vue-video-player
# 使用步骤:
第一步:cnpm install vue-video-player
第二步:在main.js中引入
require('video.js/dist/video-js.css');
require('vue-video-player/src/custom-theme.css');
import VideoPlayer from 'vue-video-player'
Vue.use(VideoPlayer);
第三步:把静态资源(图片)放到assrts/img文件夹
enum.svg
chapter_playter.svg

1.3 前端路由跳转
# 前端路由跳转
# 在html中
<router-link to='/detail'>点我看美女</router-link>
# 在js中
this.$router.push('/detail')
this.$router.go(-1) # -1 表示后退到上个页面
# 方式一:前端路由跳转时,携带参数 '/course/detail/4'
-router/index.js中
{
path: '/course/detail/:pk',
name: 'CourseDetail',
component: CourseDetail
},
-在路由跳转中-传递参数
<router-link to='/course/detail/4'>点我看美女</router-link>
-在详情页面中-获取参数
-this.$route.params.pk # 就拿到4
# 方式二:前端路由跳转时,携带参数 '/course/detail/?pk=4'
-router.js中
{
path: '/course/detail/',
name: 'CourseDetail',
component: CourseDetail
},
-在路由跳转中-传递参数
<router-link to='/course/detail/?pk=4'>点我看美女</router-link>
-在详情页面中-获取参数
-this.$route.query.pk # 就拿到4
# 前端this.$router 和this.$route的区别
-this.$router 是路由对象,能够实现路由的跳转
-this.$router.push('/home')
-this.$router.go(-1) # -1 表示后退到上个页面
-this.$route 是当前路径对象,能够获取当前路径的一些参数
2 课程详情后台
视图类
# 根据id查询课程详情接口
# 查询所有和查询单个接口,用一个视图即可 # 就可以 /actual/'课程id' get获取单一课程
# 直接在获取所有课程接口中,继承RetrieveModelMixin
class CourseViewSet(GenericViewSet, ListModelMixin, RetrieveModelMixin):
# 根据课程id,查询该课程所有的章节(章节中带课时)接口
-查询所有课程章节,带根据课程id过滤
class CourseChapterViewSet(GenericViewSet, ListModelMixin):
queryset = CourseChapter.objects.all().filter(is_show=True, is_delete=False).order_by('orders')
serializer_class = CourseChapterSerializer
# 根据课程过滤功能
filter_backends = [DjangoFilterBackend]
filter_fields = ['course']
序列化类
# 课时序列化类
class CourseSectionSerializer(serializers.ModelSerializer):
class Meta:
model = CourseSection
fields = ['id', 'name', 'section_type_name', 'section_link', 'duration', 'free_trail']
# 章节序列化类
class CourseChapterSerializer(serializers.ModelSerializer):
# 把当前章节下所有课时拿出来(三种方式)
# 子序列化:字段名必须是外键关系的字段名(通过章节获取课时是反向,故就是related_name的值;正向就是字段名),不然就找不到该属性 *******
# course_sections = ... # 报错
coursesections = CourseSectionSerializer(many=True)
class Meta:
model = CourseChapter
fields = ['id', 'name', 'summary', 'pub_date', 'coursesections']
路由
# api/v1/course/actual/ ---->get请求就能获取所有课程
# api/v1/course/actual/'课程id' ---->get请求就能获取单一课程
router.register('actual',views.CourseViewSet,'actual')
# api/v1/course/chapter/?course='课程id' ---->get请求就能获取所有课程的章节,需要带通过课程id过滤功能
router.register('chapter',views.CourseChapterViewSet,'chapter')
3 视频托管
视频播放,可以放本地服务器(后台/media文件夹),但消耗资源带宽和硬盘,也不易维护
# 常见的文件/图片存储方案:
方案一:使用nginx搭建图片服务器
方案二:使用开源的分布式文件存储系统,例如Fastdfs、HDFS等
方案三:使用云存储,例如阿里云、七牛云等
# 第三方视频托管:把视频放在第三方,消耗第三方的资源,我们只需要付钱就可以了
# 第三方文件服务器
-阿里oss
-七牛云(国内go语言推崇者)
-腾讯
-...
# 大规模公司,不用第三方(自建文件存储) --分布式文件存储
-ceph # 大型文件存储
-Fastdfs(我给你搭一个,你用我的) # 小型文件存储
-https://zhuanlan.zhihu.com/p/372286804
-minio(自己搭在云服务器上) # 小型文件存储
-go-fastdfs
-...
# 七牛云--注册账号、实名认证--新建存储空间
3.1 七牛云 上传文件-python.sdk
from qiniu import Auth, put_file, etag
import qiniu.config
# 需要填写你的 Access Key 和 Secret Key
access_key = ''
secret_key = ''
# 构建鉴权对象
q = Auth(access_key, secret_key)
# 要上传的空间
bucket_name = 'lqz'
# 上传后保存的文件名
key = '致命诱惑1.mp4'
# 生成上传 Token,可以指定过期时间等
token = q.upload_token(bucket_name, key, 3600)
# 要上传文件的本地路径
localfile = './致命诱惑.mp4'
ret, info = put_file(token, key, localfile, version='v2')
print(info)
# 公开空间,直接获取文件的外链地址
# 私有空间,需要下载获取文件的外链地址
3.2 七牛云 私有空间 获取文件外链地址-python.sdk
# 获取私有空间文件地址下载
import requests
from qiniu import Auth
access_key = '6xqCZFAOkEGRttd5xqqg2fYyF5rmokO6-QDFJGjy'
secret_key = 'jW5jjym9nAb4-pR2o0LAoxqU_6w2DTTPlT1Ys7bc'
bucket_domain = 'r8x65c9xr.hn-bkt.clouddn.com' # 存储空间的域名
key = 'python学习.mp4' # 文件名
q = Auth(access_key, secret_key)
# 有两种方式构造base_url的形式
# base_url = 'http://%s/%s' % (bucket_domain, key)
# 或者直接输入url的方式下载
# base_url = 'http://domain/key'
base_url = 'http//r8x65c9xr.hn-bkt.clouddn.com/python学习.mp4'
# 可以设置token过期时间
private_url = q.private_download_url(base_url, expires=3600)
print(private_url)
r = requests.get(private_url)

5 搜索接口
视图类
# 搜索接口
class CourseSearchViewSet(GenericViewSet, ListModelMixin, RetrieveModelMixin):
queryset = Course.objects.all().filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseSerializer
# 带分页
pagination_class = CommonPageNumberPagination
# 搜索,按名字模糊搜索,或者按介绍搜索
filter_backends = [SearchFilter]
search_fields = ['name', 'brief']
# 如果想全文检索----》只要在brief中有关键字,就能搜索出来---》类似于百度
# 如果使用mysql的like搜索,数据量越大,速度越慢 (drf 内置过滤类就是 like模糊匹配)
# 后期咱们需要使用专业的搜索引擎---》Elasticsearch:分布式全文检索引擎
# 如果这个搜索接口,返回多种课程,需要重写list,并重新拼接返回的数据json对象
# [{},{},{}]--->{'actual_course':[],'free_course':[],'lite_course':[]}
# 思路:继承apiview, 自己分别获取三个表的实例对象,然后通过三个对应的序列化类,得到数据,然后再按格式封装返回
# def get(self, request, *args, **kwargs):
# # 只返回了实战课,后期有免费,轻课,一次性返回
# actual = models.Course.objects.filter(is_delete=False, is_show=True).order_by('orders').all()
# actual_ser = serializer.CourseSerializer(actual, many=True)
# res={'actual_course':actual_ser.data ,'free_course':[],'lite_course':[]}
# return Response(data=res)
路由
# api/v1/course/search/?word=='' ---->get请求就能搜索课程(正常情况,实战课,免费课,轻课)

7 支付宝支付介绍
# 购买课程,付款
# 支付宝支付,微信支持,银联支付
支付宝--开放平台--文档--网页&移动应用--开放能力--支付能力--电脑网站支付
https://opendocs.alipay.com/open/270/106291
# 申请使用支付宝支付,需要有商户号(用户把钱付款到你的商户号中)
-收手续费
-商户号要申请,需要有公司的营业执照(不需要营业执照也可以申请--》笔记)
-需要商户号,公钥,私钥
-开发测试阶段,使用沙箱环境(测试环境)---》钱都是假的,可以无限花钱
# 支付宝沙箱环境
-https://openhome.alipay.com/platform/appDaily.htm?tab=info
-实名认证一下---》看到沙箱环境
-下载app后(能看到9000多万现金)
-账号:bfxtlv8393@sandbox.com
-密码:111111
-支付密码:111111
# 支付宝支付的流程
项目网站点击
----》立即购买
----》跳转到支付宝支付页面
----》手机扫码(手动输入用户名密码),把钱付给了支付宝(你的商户中)
----》跳转回项目网站支付成功页面 # 支付宝会携带订单号 回调项目地址,项目后台通过订单号,修改订单状态即可(从待支付修改为已支付)
# 支付宝支付的开发流程
-前端点击立即购买(需要登录)
-调项目的下单接口---》生成订单(订单状态是待支付),并返回支付连接
-前端拿到支付连接---》跳转到支付连接(支付宝地址)
-用户付款完成后,支付宝会回调到项目前端(get回调)---》项目前端显示支付成功
-支付宝还有一个post回调---》项目需要配合一个接口---》修改订单状态(已支付)
# 咱们要写的接口
-下单接口
-支付宝的post回调接口
-前端支付成功回调接口(不着急)
# 支付宝官方提供了:API和SDK(官方有python,但分什么服务端和客户端,难搞)
-第三方封装了SDK # python-alipay-sdk
-下载,生成支付连接
-生成公钥和私钥(https://opendocs.alipay.com/open/291/105971)
-公钥
-私钥
-支付宝公钥 # 是通过公钥在支付宝网站上配置生成的
-使用私钥和支付宝公钥(***********)
