Question

我正在使用付款网关（无现金付款网关）向我正在开发的网站添加定期付款系统。付款完成后，付款网关会使用一些带有POST请求为 given here的参数重定向到我的wesbite网址。我无法读取这些参数。这是我的第一个Web开发项目，在这里我有点困惑。在文档中提到这是POST请求，但后端request.method提供了GET方法。我正在使用以下代码

@csrf_exempt
@login_required
def cashfree_response(request):
    if request.method == "POST":
        print('inside post method')
    if request.method == "GET":
        print('inside get method')
        sub_ref = request.GET['cf_subReferenceId']

如何读取付款网关传递的cf_subReferenceId参数值和其他参数值？我也尝试使用sub_ref = request.GET.get('cf_subReferenceId')，但返回None。如何读取这些参数以及如何检查支付网关是否正在发送任何参数？

更新：

我联系了无现金支付网关，他们回答这是POST请求。但是当我print(request.method)时显示为GET。他们给我发送了几个PHP文件，但我不知道PHP。以下是他们发送给我的PHP文件。有人可以帮助我确定什么是返回方法以及如何读取返回参数吗？

<?php  
     $secretkey = "60e9cfebec82c9693d9423011fc2898766119d1c";
     $cf_subReferenceId = $_POST["cf_subReferenceId"];
     $cf_subscriptionId = $_POST["cf_subscriptionId"];
     $cf_authAmount = $_POST["cf_authAmount"];
     $cf_orderId = $_POST["cf_orderId"];
     $cf_referenceId = $_POST["cf_referenceId"];
     $cf_status = $_POST["cf_status"];
     $cf_message = $_POST["cf_message"];
     $signature = $_POST["signature"];
     $data = "";
     $postData = $_POST;
     ksort($postData);
     foreach ($postData as $key => $value) {
     if (substr($key, 0, 3) == "cf_") {
     $data .= $key . $value;
}
 }
 //echo($data);
         //die();
         $hash_hmac = hash_hmac('sha256', $data, $secretkey, true) ;
         $computedSignature = base64_encode($hash_hmac);
         if ($signature == $computedSignature) {
         print_r("yes");
         }else{
         print_r("no");
         }
?>

在安装debug-toolbar之后，它显示未传递任何参数

在views.py中创建计划和订阅，并将用户发送到authlink。它正在创建计划和订阅，我被重定向到authlink，在那里我可以输入卡的详细信息并进行授权。由于它是测试模式，因此我选择了成功，然后返回到我给出的URL。那是我没有任何参数的地方。

def payment_process(request):
    if request.method == "POST":
        Sub_value =  int(request.POST.get('sub_value'))
        creator =  request.POST.get('creator')
        url = "https://test.cashfree.com/api/v2/subscription-plans"
        appID = settings.CASHFREEID
        secretKey = settings.CASHFREESECRETKEY

        return redirect(response_text['authLink'])

正如注释中所读，重定向通常是使用浏览器中的GET方法进行的。

要在Django中获取GET参数，您可以check this solution。

另一方面，如本video of Cashfree所示，您可以从浏览器的“网络”标签中进行调试，检查“保存日志”选项，发出请求并检查标头值。

Django：从POST请求中读取参数
