「路飞项目14」支付宝支付
1 搜索后台接口
# 咱们写的很简单，但是公司中这个接口是最牛逼的
-搜索接口中带个性化推荐
# 咱们只写了实战课，搜索要搜索所有跟用户输入相关的
-实战课
-轻课
-免费
-资料 文档
1.1 视图类
from utils.common_response import APIResponse
from rest_framework.filters import SearchFilter
# 搜索就是查询所有，带过滤 按课程名搜索
class SearchCourseView(GenericViewSet, ListModelMixin):
serializer_class = CourseSerializer
queryset = Course.objects.filter(is_delete=False, is_show=True).order_by('orders')
filter_backends = [SearchFilter]
search_fields = ['name', 'brief']
# 1 brief内容非常多，如果使用mysql的搜索，like 全文搜，随着数据量越来越大，搜索越来越慢---》分布式全文检索引擎elasticsearch
# def list(self, request, *args, **kwargs):
# res=super().list(request, *args, **kwargs)
# actual_course=res.data.data # [{},{}]
# free_course=[{},{},{}]
# light_course=[{},{},{}]
# others=[{},{},{}]
# return APIResponse(actual_course=actual_course,free_course=free_course)
# 2 有很多课程，免费课，轻课，文档。。。
# 3 存疑
1.2 路由
router.register('search', SearchCourseView, 'search')
2 搜索前台
2.1 搜索导航栏Header.vue div下面

3 支付宝支付介绍
# 购买课程，付款---》支付宝支付
- 支付宝支付（即便没有账号，也可以测试）元
- 微信支付（需要用营业执照申请商家帐号）分
- 银联支付
# 支付宝支付介绍
https://opendocs.alipay.com/open/203/106493
# 集成支付宝流程
-我们自己的网站：点击购买按钮---》向我们后端发送请求---》携带购买商品信息---》生成订单，入库，订单是未支付状态-----》生成支付宝支付链接----》返回给前端
-前端拿到支付链接---》get请求打开----》咱们的前端就来到了支付宝的页面--》用户掏出手机扫描支付---》付款完成----》支付宝收到了钱----》get回调（咱们配置回调地址）----》跳回我们自己的网页---》支付宝还会发送post请求给我们后端----》我们要验签，通过后，把订单状态改为已支付状态
# 使用第三方sdk
-基于官方的api封装的
-pip install python-alipay-sdk --upgrade
# 要使用支付宝：需要营业执照注册，咱们没有，咱们使用沙箱环境测试， 测试通过，后期只要换成公司的商户号和支付宝公钥私钥即可
#沙箱环境：https://openhome.alipay.com/platform/appDaily.htm?tab=info
# 需要生成公钥私钥：非对称加密---》公钥加密，私钥解密
https://opendocs.alipay.com/common/02kipl
# 生成公钥和私钥
# 把你的公钥，配置在支付宝账号里,生成支付宝公钥----》写支付，需要用支付宝公钥和私钥

5.3 下单接口
# 前端传入数据---》在订单表中插入记录，生成支付链接，返回给前端
-前端传入数据：{'subject':'某个课程', 'total_amount'：100, 'pay_type':1, 'courses':[1,2,3]}
-后端做的事情--要保存，要校验---》序列化类来做
# 1）订单总价校验
# 2）生成订单号：唯一的
使用uuid，数据库自增，当前时间+redis 自增，雪花算法：生成分布式唯一id，美团leaf算法
# 3）获取支付用户：request.user
# 4）支付链接生成：支付宝支付链接
# 5）入库(两个表)的信息准备
