如何在Python中获取Javascript onSuccess响应对象变量？

背景：

在Django应用程序中，我有一个使用外部API执行操作（生成付款）的模板。API调用是在Javascript中完成的

成功时，API返回一个

响应

对象。这在测试中效果很好

function makePayment(applicationAmount) {
    let paymentEngine = RmPaymentEngine.init({
        key: 'abcd'
        firstName: '{{ user.f_name }}',
        onSuccess: function(response) {
            console.log('callback Successful Response', response);
            // TODO: Add a function to post the payment records to the database
            // response from the API contains a dictionary like (read json) object
            // how can I get that response object in Python and use those response
            // object values to update a django model database records
        },
        onError: function(response) {
            console.log('callback Error Response', response);
            // TODO: Add a function to throw an error message
        },
        onClose: function() {
            console.log("closed");
        }
    });
}

问题：

如何在Python中获取

onSuccess

response

对象变量，并使用这些

response

对象值来更新django模型数据库记录

我很高兴被引导到一个简单的资源来解释这个过程，而不是一些需要花费数小时才能理解的非常复杂的东西。

使用@Lag11和@Arount的想法和一个精彩的教程，我创建了两个基于函数的视图，一个用于服务“页面”，另一个用于处理“页面发布到数据库”

总之，我是在模板中完成的：

function makePayment(applicationAmount) {
    let paymentEngine = RmPaymentEngine.init({
        key: 'abcd'
        firstName: '{{ user.f_name }}',
        onSuccess: function(response) {
            console.log('callback Successful Response', response);

            // start new additions

            data = {
                "payer_email": "{{ user.email }}",
                "payer_phone": "{{ user.phone }}",
                "payment_amount_total": response.amount,
            }

            $.ajax({
                type: 'POST',
                url: "{% url 'post_purchase_form' %}",
                data: data,
                onSuccess: function (response) {
                    console.log('callback db post Successful', response);  
                },
                error: function (response) {
                    // alert the error if any error occured
                    alert(response);
                }
            })
            // end new additions
        },
        onError: function(response) {
            console.log('callback Error Response', response);
            // TODO: Add a function to throw an error message
        },
        onClose: function() {
            console.log("closed");
        }
    });
}

def application_form_view(request):
    user = request.user
    form = ApplicationForm(instance=user)

    return render(request, 'application_form.html', {'form': form, 'user': user})

def post_application_form_view(request):
    # request should be ajax and method should be POST.
    if request.is_ajax and request.method == "POST":
        # get the form data
        form = ApplicationForm(request.POST, request.FILES)
        # save the data and after fetch the object in instance
        if form.is_valid():
            instance = form.save()
            # serialize in new FormPurchase object in json
            ser_instance = serializers.serialize('json', [ instance, ])
            # send to client side.
            return JsonResponse({"instance": ser_instance}, status=200)
        else:
            # some form errors occured.
            return JsonResponse({"error": form.errors}, status=400)

    # some error occured
    return JsonResponse({"error": "unknown errors"}, status=400)

在视图.py中：

function makePayment(applicationAmount) {
    let paymentEngine = RmPaymentEngine.init({
        key: 'abcd'
        firstName: '{{ user.f_name }}',
        onSuccess: function(response) {
            console.log('callback Successful Response', response);

            // start new additions

            data = {
                "payer_email": "{{ user.email }}",
                "payer_phone": "{{ user.phone }}",
                "payment_amount_total": response.amount,
            }

            $.ajax({
                type: 'POST',
                url: "{% url 'post_purchase_form' %}",
                data: data,
                onSuccess: function (response) {
                    console.log('callback db post Successful', response);  
                },
                error: function (response) {
                    // alert the error if any error occured
                    alert(response);
                }
            })
            // end new additions
        },
        onError: function(response) {
            console.log('callback Error Response', response);
            // TODO: Add a function to throw an error message
        },
        onClose: function() {
            console.log("closed");
        }
    });
}

def application_form_view(request):
    user = request.user
    form = ApplicationForm(instance=user)

    return render(request, 'application_form.html', {'form': form, 'user': user})

def post_application_form_view(request):
    # request should be ajax and method should be POST.
    if request.is_ajax and request.method == "POST":
        # get the form data
        form = ApplicationForm(request.POST, request.FILES)
        # save the data and after fetch the object in instance
        if form.is_valid():
            instance = form.save()
            # serialize in new FormPurchase object in json
            ser_instance = serializers.serialize('json', [ instance, ])
            # send to client side.
            return JsonResponse({"instance": ser_instance}, status=200)
        else:
            # some form errors occured.
            return JsonResponse({"error": form.errors}, status=400)

    # some error occured
    return JsonResponse({"error": "unknown errors"}, status=400)

您不能将Javascript对象传递给Python，它是两种不同的语言，一种在用户浏览器中运行，另一种在服务器上运行。当支付成功时，处理某件事情的最佳方法是在

OnSuccess

函数（Javascript）中调用内部API（Python），并通过POST或GET参数将

response

（Javascript）中的预期参数传递给Python API。在OnSuccess函数中，使用ajax将响应发送到后端，以处理您希望使用pythonThanks@Arount执行的操作。你对我如何实现这个或一个例子有指导吗？
