# 方式一：自己写过滤类，配置到视图类的
# 继承了drf的过滤类,自己重写一下
# course/SearchBackend.py
class SearchByPrice(BaseFilterBackend):
def filter_queryset(self, request, queryset, view):
price_gt=request.GET.get('price_gt')
price_lt=request.GET.get('price_lt')
queryset = queryset.filter(price__gt=price_gt,price__lt=price_lt)
return queryset
# 配置到视图类
# course/views.py/CourseView
filter_backends = [SearchByPrice]
'''===============================>'''
# 方式二：借助django—fileter
# 1 写一个类：
# course/SearchBackend.py
from . import models
from django_filters import filters
class CourseFilterSet(FilterSet):
# 区间过滤：field_name关联的Model字段；lookup_expr设置规则；gt是大于，gte是大于等于；
min_price = filters.NumberFilter(field_name='price', lookup_expr='gte')
max_price = filters.NumberFilter(field_name='price', lookup_expr='lte')
class Meta:
model = models.Course
# 如果过滤条件仅仅就是Model已有的字段，方式一更好
# 但是方式二可以自定义过滤字段
fields = ['course_category','min_price', 'max_price']
# 2 配置到视图类上
# course/views.py/CourseView
filter_backends = [DjangoFilterBackend]
filter_class = CourseFilterSet
1 搜索的后端接口
-课程标题（要有搜的关键字）
-课程简介（要有搜的关键字）
-专业的搜索引擎（ES：专注于大数据量的搜索）
2 这次咱们写的就是去数据库查
course/views.py
from rest_framework.filters import SearchFilter
class CourserSearchView(GenericViewSet,ListModelMixin):
queryset = Course.objects.filter(is_delete=False, is_show=True).order_by('-orders')
serializer_class =CourseSerializer
# 内置搜索
filter_backends = [SearchFilter]
search_fields = ['name', 'brief']
pagination_class = BasicPagination
# def list(self, request, *args, **kwargs):
# res=super().list(request, *args, **kwargs)
# # 实战课数据
# res.data
#
# # 免费课数据
# data2
#
# # 轻课
# data3
# return APIRespone(lite_course=data3,)

1 使用在线支付功能
-支付宝支付（讲它）
-微信支付
-银联支付（用的比较少）
2 使用支付宝支付
-商户号（营业执照）----》沙箱环境（测试）
-appkey： 测试的key
-secretkey：
3 对称加密和非对称加密
-对称加密：加密密码和解密密码是一个
-非对称加密：公钥和私钥
-公钥加密（即便截获到加密内容和公钥，只要没有私钥，也解不出来）
-私钥解密
4 商家号（营业执照申请），沙箱环境测试
用户名：babdgw8208@sandbox.com
密码：111111
用户号：测试账号
沙箱版的支付宝
用户名：bfxtlv8393@sandbox.com
密码：111111
支付密码：111111
5 生成公钥，私钥
-借助于支付宝提供的工具：https://opendocs.alipay.com/open/291/105971#LDsXr
-用这个工具生成公钥和私钥
-把公钥配置在支付宝的网站上----》生成一个支付宝公钥
6 前端点击立即支付，发送请求
-post请求，数据库写入操作
-生成一个订单（订单表插入数据，订单状态为待支付）
-生成支付链接，返回给前端
-前端拿到支付链接，跳转到支付页面（支付宝页面）
-用户扫描付款（输入用户名密码付款）
-支付宝收到付款成功，get回调咱们的系统
-支付宝还会发送post回调，咱们系统接收到以后，修改订单状态
7 流程：
-1 生成私钥和公钥
-2 把公钥配置在沙箱环境
-3 复制出支付宝公钥，粘贴在项目中
-4 复制出私钥粘贴在项目中
-5 视图类
-6 前端发送post请求，测试生成的支付链接，完成支付
# 1、在沙箱环境下实名认证：https://openhome.alipay.com/platform/appDaily.htm?tab=info
# 2、电脑网站支付API：https://docs.open.alipay.com/270/105900/
# 3、完成RSA密钥生成：https://docs.open.alipay.com/291/105971
# 4、在开发中心的沙箱应用下设置应用公钥：填入生成的公钥文件中的内容
# 5、Python支付宝开源框架：https://github.com/fzlee/alipay
# >: pip install python-alipay-sdk --upgrade
# 7、公钥私钥设置
"""
# alipay_public_key.pem
-----BEGIN PUBLIC KEY-----
支付宝公钥
-----END PUBLIC KEY-----
# app_private_key.pem
-----BEGIN RSA PRIVATE KEY-----
用户私钥
-----END RSA PRIVATE KEY-----
