Python Django paypal在IPN模拟器中工作，但不在沙箱中工作

我已经在django paypal IPN教程之后编写了一个IPN，但是我的似乎不起作用。它在PayPal IPN模拟器上运行没有问题，我收到IPN并执行代码，但是当我尝试在沙箱模式下执行时，付款没有响应

观点：

from django.core.urlresolvers import reverse
from django.shortcuts import render
from paypal.standard.forms import PayPalPaymentsForm

def view_that_asks_for_money(request):

    # What you want the button to do.
    paypal_dict = {
        "business": "receiver_email@example.com",
        "amount": "100.00",
        "item_name": "Product",
        "invoice": "100",
        "notify_url": "http://myip/paypal/",
        "return_url": "https://www.example.com/your-return-location/",
        "cancel_return": "https://www.example.com/your-cancel-location/",
        "custom": "Upgrade all users!",  # Custom command to correlate to some function later (optional)
    }

    # Create the instance.
    form = PayPalPaymentsForm(initial=paypal_dict)
    context = {"form": form}
    return render(request, "payment.html", context)

from paypal.standard.models import ST_PP_COMPLETED
from paypal.standard.ipn.signals import valid_ipn_received

def show_me_the_money(sender, **kwargs):
    ipn_obj = sender
    category = Category(name="Got IPN")
    category.save()
    if ipn_obj.payment_status == ST_PP_COMPLETED:
        category = Category(name="Good Buzz, complete")
        category.save()
    else:
        category = Category(name="Bad Buzz, not complete")
        category.save()


valid_ipn_received.connect(show_me_the_money)
invalid_ipn_received.connect(show_me_the_money)

当我将IPN发送到时：它可以工作，但不能通过沙箱。

您找到解决方案了吗？我也有同样的错误：/我记不清了，但请确保您在prod环境中完全运行。如果您在live中发送付款，但它尝试在sandbox中验证，它将失败。您找到解决方案了吗？我也有同样的错误：/我记不清了，但请确保您在prod环境中完全运行。如果您在live中发送付款，但它尝试在沙箱中进行验证，则将失败。
