Stripe Integration with Django 给出一个类型错误，说 __init__() 需要 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 预建结帐页面集成到我的 django 项目中。

条纹文档适用于烧瓶，因此我正在尝试阅读或观看有关如何将它们转换为 django 的 youtube 教程，但我并没有真正做到。教程中的代码与当前的条带文档不同

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"

我可以让 checkout.html 显示，但是当我单击结帐按钮时出现此错误

我也试过这个页面上的代码

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"

还是会报同样的错误

谁能帮我解决它？

谢谢

编辑：添加 urls.py 和landing.html 以供参考

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landing.html

<!DOCTYPE html>
<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>
    <script src="https://js.stripe.com/v3/"></script>
  </head>
  <body>
    <section>
      <div class="product">
        <img
          src="https://i.imgur.com/EHyR2nP.png"
          alt="The cover of Stubborn Attachments"
        />
        <div class="description">
          <h3>Stubborn Attachments</h3>
          <h5>$20.00</h5>
        </div>
      </div>
      <form action="/create-checkout-session" method="POST">{% csrf_token %}
        <button type="submit">Checkout</button>
      </form>
    </section>
  </body>
</html>

Answer 1

看起来这与您的 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 配置中的问题。

Answer 2

更新你的 urls.py：

    path('create-checkout-session', CreateCheckoutSessionView.as_view(), name='create-checkout-session'),
