创建订单并生成支付链接接口

1.创建订单并生成支付链接接口

1.1 goods/urls.py中注册路由

urlpatterns = [ 
	path('getpayurl/', views.PayUrlView.as_view()), # /goods/getpayurl/ 
]

1.2 goods/views.py 中写视图函数

from rest_framework.views import APIView 
from rest_framework.permissions import AllowAny, IsAuthenticated 
from rest_framework.response import Response 
from .models import Goods,Orders,GoodsCourse 
from goods.utils import get_order_id, get_pay_url, alipay 

from decimal import Decimal 
class PayUrlView(APIView): 
	permission_classes = (IsAuthenticated,) 
	def post(self, request): 
		# 1. 获取课程id,获取购买途径(普通购买, 促销购买) 获取用户 
		goods_id = request.data.get('goods_id') 
		goods = Goods.objects.get(id=goods_id) user = request.user 
		# 2. 下定单 
		order_id = get_order_id() 
		if user.vip.vip_type == '1': # 普通会员 
			goods_price = goods.price * Decimal('0.80').q
