django - Stripe Integration 与 Django 给出类型错误，指出 __init__() 采用 1 个位置参数，但给出了 2 个

Question

您好，我一直在尝试学习如何将 Stripe 预构建结帐页面集成到我的 django 项目中。

stripe 文档是针对 Flask 的，所以我正在尝试阅读或观看 YouTube 教程，了解如何将它们转换为 django，但我并没有真正取得任何进展。教程中的代码与当前的 stripe 文档不同

https://stripe.com/docs/checkout/integration-builder

from django.shortcuts import render, redirect
import stripe
from django.conf import settings
from django.http import JsonResponse
# Create your views here.
from django.views import View
from django.views.generic import TemplateView

stripe.api_key = settings.STRIPE_SECRET_KEY


class ProductLandingPageView(TemplateView):
    template_name = "landing.html"


class CreateCheckoutSessionView(View):
    def post(self, request,  *args, **kwargs):
        YOUR_DOMAIN = "http://127.0.0.1:8000"
        checkout_session = stripe.checkout.Session.create(
            payment_method_types=['card'],
            line_items=[
                {
                    # TODO: replace this with the `price` of the product you want to sell
                    'price': '{{PRICE_ID}}',
                    'quantity': 1,
                },
            ],
            mode='payment',
            success_url=YOUR_DOMAIN + "/success",
            cancel_url=YOUR_DOMAIN + "/cancel",
        )

        return redirect(checkout_session.url, code=303)


class Successview(TemplateView):
    template_name = "success.html"


class Cancelview(TemplateView):
    template_name = "cancel.html"

我可以显示 checkout.html，但是当我单击结账按钮时，出现此错误

我也尝试过此页面上的代码

https://stripe.com/docs/payments/accept-a-payment?platform=web&ui=checkout

from django.shortcuts import render, redirect
import stripe
from django.conf import settings
from django.http import JsonResponse
# Create your views here.
from django.views import View
from django.views.generic import TemplateView

stripe.api_key = settings.STRIPE_SECRET_KEY


class ProductLandingPageView(TemplateView):
    template_name = "landing.html"


class CreateCheckoutSessionView(View):
    def post(self, request,  *args, **kwargs):
        YOUR_DOMAIN = "http://127.0.0.1:8000"
        checkout_session = stripe.checkout.Session.create(
            payment_method_types=['card'],
            line_items=[{
                'price_data': {
                    'currency': 'usd',
                    'product_data': {
                        'name': 'T-shirt',
                    },
                    'unit_amount': 2000,
                },
                'quantity': 1,
            }],
            mode='payment',
            success_url=YOUR_DOMAIN + "/success",
            cancel_url=YOUR_DOMAIN + "/cancel",
        )

        return redirect(checkout_session.url, code=303)


class Successview(TemplateView):
    template_name = "success.html"


class Cancelview(TemplateView):
    template_name = "cancel.html"

仍然得到同样的错误

谁能帮我解决这个问题吗？

谢谢

编辑:添加urls.py以及landing.html以供引用

from django.contrib import admin
from django.urls import path
from products.views import CreateCheckoutSessionView, ProductLandingPageView, Cancelview, Successview

urlpatterns = [
    path('admin/', admin.site.urls),
    path('cancel/', Cancelview.as_view(), name='cancel'),
    path('success/', Successview.as_view(), name='success'),
    path('create-checkout-session', CreateCheckoutSessionView, name='create-checkout-session'),
    path('', ProductLandingPageView.as_view(), name='landing-page')


]

这是登陆.html

<!DOCTYPE html>

  <head>
    <title>Buy cool new product</title>
    <link rel="stylesheet" href="style.css">
    <script src="https://polyfill.io/v3/polyfill.min.js?version=3.52.1&features=fetch"></script>

Answer 1

看起来这与 path 定义中缺少 as_view() 有关: https://stackoverflow.com/a/53572256/12474862

这似乎不是与 Stripe 相关的错误，而是 Django 配置中的某些错误。
