1.订单支付回调接口

1.1 goods/urls.py中添加路由

urlpatterns = [
    path('peyment/', views.PayMentView.as_view()),  # /goods/peyment/
]

1.2 goods/views.py中写视图函数

from user.models import Vip
import datetime
from course.models import UserCourse
class PayMentView(APIView):
    permission_classes = (AllowAny,)

    def post(self, request):
        # 1. 获取了支付宝返回的数据
        data = request.data
        # 2.修改订单信息为已支付状态
        sign = data.pop('sign')
        """
        "sign": "Sv......kEoobbA==", 
        """
        order = Orders.objects.get(order_id=data['out_trade_no'])
        order.trade_no = data['trade_no']
        order.pay_time = data['timestamp']
        order.status = 2
        order.save()
        # 3. 处理用户购买课程流程
        # 3.1 给 UserCourse 表增加 购买课程
        # goods = order.goods
        user = order.user
        course = order.goods.course
        UserCourse.objects.create(user=user,course=course)
        return Response({"code": 0, "msg": "购买成功"})
