订单生成回调接口

 

1. 支付回调页支付信息
   

• vue需要把支付凭证传递给django，django把订单状态改为已支付，并在UserCourse表中存储用户购买课程信息

mounted() {
    this.query = this.$route.query
    payment_post(this.query).then((resp) => {
        // ({"code": 999, "msg": "非法请求"})
        this.msg = resp.msg
    })
},

2.goods/views 中写视图函数

class PaymentApi(APIView):

    def post(self, request):
        data = request.data
        # 获取订单对象
        order_obj = Orders.objects.get(order_id=data.get('out_trade_no'))
        # 需要保存支付宝订单信息，支付时间，支付状态
        order_obj.trade_no = data.get('trade_no')
        order_obj.pay_time = data.get('timestamp')
        order_obj.status = 2
        order_obj.save()
        # 获取用户购买的课程对象和当前用户
        course_obj = Course.objects.get(pk=order_obj.goods.course_id)
        user = UserCourse(user=request.user, course=course_obj)
        user.save()
        return Response({"code": 200, "msg": "OK"})

3.goods/urls 中注册路由

urlpatterns = [
    path('payment/', views.PaymentApi.as_view())         # /goods/payment/
]
