Django 支付宝异步接收不到请问能帮我看一下么

我的代码如下:

@login_required(login_url='/accounts/login/') @csrf_exempt def apliy_check_pay(request): alipay=AliPay( appid=ALIPAY_APPID, app_notify_url=set_url, app_private_key_path=os.path.join(settings.BASE_DIR, "app/app_private_key.pem"), alipay_public_key_path=os.path.join(settings.BASE_DIR, "app/alipay_public_key.pem"), sign_type="RSA2", debug=True, ) if request.method == 'POST': mydata=request.POST.dict() signature = mydata.pop("sign") success=alipay.verify(mydata,signature) if success: order_sn=mydata['out_trade_no'] trade_no=mydata['trade_no'] myfunding=Funding.objects.filter(number=order_sn) existed_orders=myfunding.update( fudingpaid=True, number=str(order_sn), trade_no=str(trade_no), ) return HttpResponse('支付成功') if request.method == 'GET': params=request.GET.dict() #test=request.GET.get('trade_status') sign=params.pop('sign',None) print(sign) status=alipay.verify(params,sign) if status: order_sn=params['out_trade_no'] trade_no=params['trade_no'] myfunding=Funding.objects.filter(number=order_sn) existed_orders=myfunding.update( fudingpaid=True, number=str(order_sn), trade_no=str(trade_no), ) return HttpResponse('支付成功') return HttpResponse('支付失败') else: return HttpResponseRedirect(reverse('accounts:payment_funding')) 

GET 是可以 GET 到的，是 POST 哪里写错了么？

使用的 github 上该封装 https://github.com/fzlee/alipay/blob/master/README.zh-hans.md
