    path('result/',views.AlipayResultView.as_view(),)
]

class AlipayResultView(APIView):
    permission_classes = [IsAuthenticated,]
    def get(self,request):
        
        # 1.创建alipay对象
        alipay = AliPay(
            appid=settings.ALIAPY_CONFIG[appid],app_notify_url=None, 默认回调url
            app_private_key_string=open(settings.ALIAPY_CONFIG[app_private_key_path]).read(), 支付宝的公钥，验证支付宝回传消息使用，不是你自己的公钥,
            alipay_public_key_string=open(settings.ALIAPY_CONFIG[alipay_public_key_pathsign_type'],1)"> RSA 或者 RSA2
            debug=settings.ALIAPY_CONFIG[debug 默认False
        )
         2.校验支付宝响应数据
        data = request.query_params.dict()  获取那一大堆的参数
        
        out_trade_no = data.get(out_trade_no')  获取商户订单号
        sign = data.pop(sign 获取签名
        success = alipay.verify(data,sign)  通过参数和签名来验证那一堆参数是不是支付宝发过来的
        if not success:
            logger.error(%s,支付宝响应数据校验失败' % out_trade_no)
            return Response(支付宝响应数据校验失败',status=status.HTTP_400_BAD_REQUEST)

          响应结果
        return Response({msg':okdata:res_data})

      // 把地址栏上面的支付结果，转发给后端
      this.send_alipay_params();

methods:{
      send_alipay_params(){
        let token = localStorage.token || sessionStorage.token;
        this.$axios.get(`${this.$settings.Host}/payment/result/${location.search}`,{
          headers:{
              'Authorization':'jwt ' + token
            }
        }).then((res)=>{  如果后端验证这些参数没有问题 购买成功页面需要的参数就可以传递过来了
          this.pay_time = res.data.data.pay_time;  支付时间
          this.course_list = res.data.data.course_list;  购买课程列表
          this.total_real_price = res.data.data.total_real_price;  课程总真实价格
        }).catch((error)=>{

 post(self,1)"> 创建alipay对象
        alipay =        )
        
         校验支付宝响应数据

{
      path: '/myorder/'2.我的订单页面-后端接口
users/urls.py

urlpatterns = [
    path(rmyorder/users/views.py


 MyOrderView(ListAPIView):
    permission_classes = MyOrderModelSerializer

     get_queryset(self):
        return Order.objects.filter(user=self.request.user)

user/serializers.py

 MyOrderModelSerializer(serializers.ModelSerializer):
     Meta:
        model = Order
        fields = [idorder_numberget_order_status_displayorder_detail_data']

order/models.py
在我的订单页面中，需要展示一些数据

 Order(BaseModel):
     order_detail_data(self):
         获取所有课程详情对象
        order_detail_objs = self.order_courses.all()
        data_list = []

         order_detail_objs:
            expire_id = order_detail.expire
            
             根据有效期来决定expire_text返回什么
            if expire_id > 0:
                expire_obj = CourseExpire.objects.get(id=expire_id)
                expire_text = expire_obj.expire_text
            else:
                expire_text = 永久有效'
        
             每个课程应该包含的字段
            order_dict = {
                course_img':contains.SERVER_ADDR + order_detail.course.course_img.url,1)">course_name:order_detail.course.name,1)">expire_text:expire_text,1)">price:order_detail.price,1)">real_price: self.real_price,1)">discount_name:order_detail.discount_name,}
             将每个课程的详情信息添加到一个列表里返回给前端
            data_list.append(order_dict)

         data_list
    

3.我的订单页面-前端
1.获取后端的订单数据
Myorder.vue

 js
get_order_data(){
         检查当前访问者是否登录了！
        let token = localStorage.token ||this.$settings.Host}/users/myorder/`,1)"> token
            }
        }).then((res)=>this.order_list = res.data;
        }).{

        })


<!-- html -->
<div ="my-order-item" v-for="(order_obj,index) in order_list" :key="index">
    ="user-data-header">
        span ="order-time">{{order_obj.pay_time.replace('T',' ')}}</span="order-num">订单号：
            ="my-older-number">{{order_obj.order_number}}divul ="nav user-data-list"="(course_obj,course_index) in order_obj.order_detail_data"li ="order-info">
            img :src="course_obj.course_img" alt=""="order-info-title">
                p ="course-title">{{course_obj.course_name}}p="price-service">{{course_obj.discount_name}}li="course-expire">{{course_obj.expire_text}}="course-price">{{course_obj.price}}="real-price">{{course_obj.real_price}}="order-status">{{order_obj.get_order_status_display}}="order-do"="btn btn2" v-if="order_obj.get_order_status_display==='已支付'">去学习 v-else-if="order_obj.get_order_status_display==='未支付'" @click="go_pay(order_obj.order_number)">去付款="order_obj.get_order_status_display==='超时取消'">超时取消 v-else>已取消ul>
>
         

2.我的订单页面点击去付款
>                   



go_pay(order_number){
        let token = localStorage.token ||this.$settings.Host}/payment/alipay/?order_number=${order_number}`,1)">              headers:{
              'Authorization':'jwt ' + token
            }

        }).then((res)=>{
          location.href = res.data.url;

        })..$message.error(error.response.data.msg);
        })
