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。。。

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

      <form class="search">
        <div class="tips" v-if="is_search_tip">
          <span @click="search_action('Python')">Python</span>
          <span @click="search_action('Linux')">Linux</span>
        </div>
        <input type="text" :placeholder="search_placeholder" @focus="on_search" @blur="off_search"
               v-model="search_word">
        <el-button icon="el-icon-search" circle @click="search_action(search_word)"></el-button>
      </form>

# 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

5.2 订单相关表设计

# Order  订单表
# OrderDetail  订单详情表


from django.db import models
from user.models import User
from course.models import Course


class Order(models.Model):
    """订单模型"""
    status_choices = (
        (0, '未支付'),

        except:
            return super().__str__()

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
     # 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
