使用 Stripe 的 Django 中的未验证错误

Question

I am creating for the very first time a payment for an e-commerce website using stripe, I am following a guide and have reviewed every step carefully but always getting Not Authenticated Error and I'm unclear what is going wrong.

I am new to Django so I'm trying to learn as much as possible from my errors.

Here is my views.py

class PaymentView(View):
    def get(self, *args, **kwargs):
        # order
        order = Order.objects.get(user=self.request.user, ordered=False)
        context = {
            'order': order
        }
        return render(self.request, "payment.html", context)

# `source` is obtained with Stripe.js; see https://stripe.com/docs/payments/accept-a-payment-charges#web-create-token
    def post(self, *args, **kwargs):
        order = Order.objects.get(user=self.request.user, ordered=False)
        token = self.request.POST.get('stripeToken')
        amount = int(order.get_total() * 100)

        try:
            charge = stripe.Charge.create(
                amount=amount,  # cents
                currency="usd",
                source=token,
            )
            # create payment
            payment = Payment()
            payment.stripe_charge_id = charge['id']
            payment.user = self.request.user
            payment.amount = order.get_total()
            payment.save()

            # assign the payment to the order
            order.ordered = True
            order.payment = payment
            order.save()

            messages.success(self.request, "Your Order was Successful ! ")
            return redirect("/")

        except stripe.error.CardError as e:
            body = e.json_body
            err = body.get('error', {})
            messages.error(self.request, f"{err.get('message')}")
            # Since it's a decline, stripe.error.CardError will be caught
            return redirect("/")

        except stripe.error.RateLimitError as e:
            # Too many requests made to the API too quickly
            messages.error(self.request, "Rate Limit Error")
            return redirect("/")

        except stripe.error.InvalidRequestError as e:
            # Invalid parameters were supplied to Stripe's API
            messages.error(self.request, "Invalid Parameters")
            return redirect("/")

        except stripe.error.AuthenticationError as e:
            # Authentication with Stripe's API failed
            # (maybe you changed API keys recently)
            messages.error(self.request, "Not Authenticated")
            return redirect("/")

        except stripe.error.APIConnectionError as e:
            # Network communication with Stripe failed
            messages.error(self.request, "Network Error")
            return redirect("/")

        except stripe.error.StripeError as e:
            # Display a very generic error to the user, and maybe send
            # yourself an email
            messages.error(
                self.request, "Something went wrong. You were not charged. Please Try Again.")
            return redirect("/")

        except Exception as e:
            # Something else happened, completely unrelated to Stripe
            # send an email to ourselves
            messages.error(
                self.request, "A serious Error Occured. We have been notified.")
            return redirect("/")

here is my model.py

class Payment(models.Model):
    stripe_charge_id = models.CharField(max_length=50)
    user = models.ForeignKey(settings.AUTH_USER_MODEL,
                             on_delete=models.SET_NULL, blank=True, null=True)
    amount = models.FloatField()
    timestamp = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.user.username

and here is the forms.py

class CheckoutForm(forms.Form):
    street_address = forms.CharField(widget=forms.TextInput(attrs={
        'placeholder': '1234 Main St',
        'class': 'form-control'
    }))
    apartment_address = forms.CharField(required=False, widget=forms.TextInput(attrs={
        'placeholder': 'Apartment or suite',
        'class': 'form-control'
    }))
    province = forms.CharField(widget=forms.TextInput(attrs={
        'class': 'form-control'
    }))
    country = CountryField(blank_label='(select country)').formfield(
        widget=CountrySelectWidget(attrs={
            'class': 'custom-select d-block w-100'
        }))
    postal_code = forms.CharField(widget=forms.TextInput(attrs={
        'class': 'form-control'
    }))
    same_shipping_address = forms.BooleanField(required=False)
    save_info = forms.BooleanField(required=False)
    payment_option = forms.ChoiceField(
        widget=forms.RadioSelect, choices=PAYMENT_CHOICES)

Thank you

I am following a guide and have reviewed every step carefully but always getting Not Authenticated Error and I'm unclear what is going wrong.

When you see this type of error from Stripe it usually means that you haven't provided a secret key, or have provided a mal-formed string as a secret key (it should be of the form sk_test_xyz (for test mode) or sk_live_xyz (for live mode).

I would double-check that you have a line where you import stripe followed by another line setting the API key as follows:

stripe.api_key = "sk_test_xyz"
