课程详情接口

# 思路一： 直接在之前写好的查询所有课程的视图类上，配置一个类即可
    class CourseView(GenericViewSet, CommonListModelMixin,CommonRetrieveModelMixin)
    返回的字段，跟详情，不太对应（详情中要求拿出所有章节和课时，但实际上只返回了4个课时）
    序列化类---》重写个详情的序列化类即可---》视图类中重写 get_serializer_class(self):
        
# 思路二：直接在之前写好的查询所有课程的视图类上，配置一个类即可
    class CourseView(GenericViewSet, CommonListModelMixin,CommonRetrieveModelMixin)
    就用之前的序列化类---》缺少课程章节
    写一个查询所有课程章节的接口，带按课程过滤
    
# 课程详情页组件  created 中向后端发送两个请求
    -查询课程详情：字段缺一些
    -查询章节：按当前课程过滤出来的，只是当前课程的所有章节
    
# common_mixin

class CommonRetrieveModelMixin(RetrieveModelMixin):
    def retrieve(self, request, *args, **kwargs):
        res = super().retrieve(request, *args, **kwargs)
        return APIResponse(result=res.data)

    
    
class CourseView(GenericViewSet, CommonListModelMixin,CommonRetrieveModelMixin):

所有章节接口

查询所有章节：带按课程过滤功能

视图类

class CourseChapterView(GenericViewSet, CommonListModelMixin):
    queryset = CourseChapter.objects.filter(is_delete=False, is_show=True).order_by('orders')
    serializer_class = CourseChapterSerializer
    filter_backends = [DjangoFilterBackend]
    filterset_fields = ['course']

路由

# http://127.0.0.1:8000/api/v1/courses/chapter/--- get
router.register('chapter', CourseChapterView, 'chapter')

序列化类

class CourseSectionSerializer(serializers.ModelSerializer):
    class Meta:
        model=CourseSection
        fields=[
            'id',
            'name',
            'orders',
            'section_link',
            'duration',
            'free_trail'
        ]

class CourseChapterSerializer(serializers.ModelSerializer):
    coursesections=CourseSectionSerializer(many=True)
    class Meta:
        model = CourseChapter
        fields = [
            'id',
            'name',
            'chapter',
            'summary',

            'coursesections' # 这个字段其实有，隐藏了，通过  章节.coursesections.all() 能拿到所有课时的 ，使用它做子序列化
        ]

搜索后台接口

## 搜索接口：在公司中是最难，最有技术含量的接口
    搜索对应推荐

## 搜索接口：可以搜索好多内容，搜的好多内容，一次性返回，前端根据不同key，渲染在不同位置

## 搜索 全去数据库搜索---》数据量越来越大，搜了好多表，速度很慢---》数据不放在数据库中---》分布式全文检索引擎---》搜索快，推荐

视图类

支付宝支付介绍

# 1 前端点击立即购买---》向咱们后端发送请求---》咱们后端生成一个支付链接(微信，支付宝支付)---》跳到不同的支付链接地址---》输入支付宝账号密码付款(手机扫码付款)----》付款成功---》支付宝收到了我们的付款---》跳转回我们自己的项目---》支付宝会调用咱们后端的某个接口通知我们付款成功---》我们收到通知，就把订单状态改为已经支付


# 2 不同的付款
    -微信支付：工商注册（营业执照），真正备案过的网址，没有测试环境
    -支付宝支付：只支持， 工商注册（企业），沙箱环境（没有商户号的前提下测试）、、
  


# 3 营业执照---》申请商家账号：2088102176466324---》使用商家账号，申请应用---》应用名称+应用id号
    -应用id号咱们付款需要
    -公司不需要你来做
    -最终：APPID 2016092000554611
    
    
# 4 使用支付宝sdk（第三方：官方的api封装的），生成支付链接
    pip install python-alipay-sdk --upgrade
    
    # 生成公钥 私钥----》支付宝工具帮咱们生成：https://opendocs.alipay.com/common/02kipl
    # 我们的公钥---》配置到支付宝平台---》生成一个支付宝公钥
    # 我们用支付宝公钥+我们私钥 做加密和认证
 

# https://opendocs.alipay.com/open/270/105898?pathHash=b3b2b667
