支付完成后无法显示成功页面

Question

我正在为我的学习电子商务项目使用 razorpay 支付网关 Web 集成，一切正常支付都可以完成我想要的只是在使用测试模式在我的订单模型中完成支付后存储一些信息

我的views.py 用于结帐

 class Checkout_Pre(View):
        def post (self, request,):
            user = request.user
            address = Address.objects.filter(default=True, user=request.user)
            cart = request.session.get('cart')
            items = Item.get_items_by_id(list(cart.keys()))
            prefer = request.POST.get('payment')
            total_price = request.POST.get('paying_price')
            total_item_price = json.loads(total_price)
            with transaction.atomic():
                order = Order.objects.create(
                        user=user,
                        total_price=total_item_price,
                        address=address.first(),
                        method = prefer,
                        )
                for item in items:
                    item_order = OrderItem.objects.create(
                        order=order,
                        item=item,
                        size=cart.get(str(item.id)),
                        price=item.price,
                        )
                request.session['cart'] = {}   
            order_currency = 'INR'
    
            callback_url = 'http://'+ str(get_current_site(request))+"/handlerequest/"
            print(callback_url)
            notes = {'order-type': "Basic order from the coolbuy website", 'key':'value'}
            razorpay_order = razorpay_client.order.create(dict(amount=total_item_price*100, currency=order_currency, notes = notes, receipt=order.order_id, payment_capture='0'))
            print(razorpay_order['id'])
            order.razorpay_order_id = razorpay_order['id']
            order.save()
               
            return render(request, 'payment/razorpaypaymentsummary.html', {'order':order, 'order_id': razorpay_order['id'], 'orderId':order.order_id, 'final_price':total_item_price, 'razorpay_merchant_id':settings.razorpay_id, 'callback_url':callback_url,})

所以付款完成后的错误是什么，我想显示 html 页面并更改 db 中的状态，但付款完成后，handlerequest throwinh me http 505 错误

@csrf_exempt
def handlerequest(request):
    if request.method == "POST":
        try:
            payment_id = request.POST.get('razorpay_payment_id', '')
            order_id = request.POST.get('razorpay_order_id','')
            signature = request.POST.get('razorpay_signature','')
            params_dict = { 
            'razorpay_order_id': order_id, 
            'razorpay_payment_id': payment_id,
            'razorpay_signature': signature
            }
            try:
                order_db = Order.objects.get(razorpay_order_id=order_id)
            except:
                return HttpResponse("505 Not Found")
            order_db.razorpay_payment_id = payment_id
            order_db.razorpay_signature = signature
            order_db.save()
            result = razorpay_client.utility.verify_payment_signature(params_dict)
            if result==None:
                amount = order_db.total_amount * 100   #we have to pass in paisa
                try:
                    razorpay_client.payment.capture(payment_id, amount)
                    order_db.payment_status = 1
                    order_db.save()
                    return render(request, 'firstapp/payment/paymentsuccess.html',{'id':order_db.id})
                except:
                    order_db.payment_status = 2
                    order_db.save()
                    return render(request, 'firstapp/payment/paymentfailed.html')
            else:
                order_db.payment_status = 2
                order_db.save()
                return render(request, 'firstapp/payment/paymentfailed.html')
        except:
            return HttpResponse("505 not found") 

知道我在处理请求视图中做错了什么

订购型号

class Order(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE,)
    address = models.ForeignKey(Address, default= True, on_delete=models.CASCADE)
    status = models.IntegerField(choices = status_choices, default=1)
    method = models.CharField(max_length=50, blank=False,)
    total_price = models.FloatField(blank=False, default=0)
    payment_status = models.IntegerField(choices = payment_status_choices, default=3)
    order_id = models.CharField(unique=True, max_length=200, null=True, default=None) 
    datetime_of_payment = models.DateTimeField(default=timezone.now)
    created_at = models.TimeField(auto_now=True, editable=False)
    razorpay_order_id = models.CharField(max_length=1000, null=True, blank=True)
    razorpay_payment_id = models.CharField(max_length=1000, null=True, blank=True)
    razorpay_signature = models.CharField(max_length=1000, null=True, blank=True)

    def __str__(self):
        return self.user.username + " " + str(self.order_id)

    def save(self, *args, **kwargs):
            if self.order_id is None and self.datetime_of_payment:
                self.order_id = self.datetime_of_payment.strftime('ORDER%Y%m%dODR') 
                return super(Order,self).save(*args, **kwargs)
            

Answer 1

问题不在于您的视图，而在于您的模型的保存方法。 在其他部分你什么都不做。你应该打电话给super。

请修改保存功能，然后尝试：

def save(self, *args, **kwargs):
    if self.order_id is None and self.datetime_of_payment:
        self.order_id = self.datetime_of_payment.strftime('ORDER%Y%m%dODR') 
    return super(Order,self).save(*args, **kwargs)

Answer 2

在你的 post 方法中，在你分配之后

order.razorpay_order_id = razorpay_order['id']

你需要保存它。好像没了。

Answer 3

在您的结帐视图中

def get(self, request, *args, **kwargs):
        order = Order.objects.get(pk = self.kwargs['order'])
        settings = SiteSettings.objects.all().first()


        # Razorpay client auth
        client = razorpay.Client(auth = (settings.razorpay_client_id, settings.razorpay_secret))
        
        if order.razorpay_order_id is None:    
            order_amount = order.total*100
            order_currency = settings.currency
            order_receipt = 'Reciept'
            notes = {'id': order.id, 'email': order.email_id, 'date':str(datetime.now()), 'amount': order.total, 'is_ios': order.is_ios, 'is_android': order.is_android}   # OPTIONAL
            data = {"amount":order_amount, "currency":order_currency, "receipt":order_receipt, "notes":notes, "payment_capture":'0'}
            razorpay_order = client.order.create(data = data)

            # Razorpay order inserted into database order
            order.razorpay_order_id = razorpay_order["id"]
            order.save()

        else:
            razorpay_order = client.order.fetch(order.razorpay_order_id)


        return render(request, self.template_name, {'settings':settings, 'order':order, 'razorpay_order': razorpay_order})

    def post(self, request, *args, **kwargs):
        o = self.kwargs['order']+ ' POST'
        
        settings = SiteSettings.objects.all().first()
        return render(request, self.template_name, {'settings':settings, 'order':o})

在你的处理程序中

    settings    = SiteSettings.objects.all().first()
    order       = Order.objects.get(id=request.POST.get('order_id'))

    #Razorpay authentication
    client = razorpay.Client(auth = (settings.razorpay_client_id, settings.razorpay_secret))
    
    #Razorpay transaction details
    razorpay_transaction_details = { 
        'razorpay_order_id':    request.POST.get('razorpay_order_id'),
        'razorpay_payment_id':  request.POST.get('razorpay_payment_id'),
        'razorpay_signature':   request.POST.get('razorpay_signature')
    }

    #Razorpay payment verification
    client.utility.verify_payment_signature(razorpay_transaction_details)
        
    #Razorpay capture payment Make sure you change this accordingly.
    payment_transaction_details = client.payment.capture(razorpay_transaction_details['razorpay_payment_id'], order.total*100, {"currency":"payment_currency"})
    order.order_description     = payment_transaction_details
    order.status                = 'paid'
    order.save()


    context = {'request': request.POST, 'order': order, 'settings':settings, 'UserData':UserData, 'Password': Password}

    return render(request, 'web/rpay-success.html', context)

您可以在其中包装一个 try except 块以呈现失败。
