当我将上下文传递给视图时，request.POST.get（）不起作用

Question

我使用Stripe为我的django网站接受一次性付款。以下代码工作正常，charge成功：

def pay(request):
    # Set your secret key: remember to change this to your live secret key in production
    # See your keys here: https://dashboard.stripe.com/account/apikeys
    stripe.api_key = "sk_test_exhH8mdKfkXkaxzvtVphJOBZ"

    # Token is created using Checkout or Elements!
    # Get the payment token ID submitted by the form:
    if request.POST.get('stripeToken'):
        print(request.POST)
        token = request.POST.get('stripeToken')

        charge = stripe.Charge.create(
            amount=999,
            currency='usd',
            description='Boosted Post',
            source=token,
        )
        print('Charge:', charge)
        return HttpResponseRedirect('/')
    else:
        print('NO')

    context = {
        'amount': 999,
    }

    return render(request, 'advertising/pay.html', context)

但是，如果我在此视图中添加上下文，则它无法正常工作（if request.POST.get('stripeToken')不会触发）：

def post_ad(request):
    boost_form = AdvertisePostForm(request.POST or None, request.FILES or None)
    if boost_form.is_valid():
        instance = boost_form.save(commit=False)
        instance.total_price = ad_price(instance.position, instance.duration)
        instance.ad = True
        instance.save()
        context = {
            'hash': instance.hash,
        }
        return pay(request, context)
    else:
        pass

    context = {
        'boost_form': boost_form
    }
    return render(request, 'advertising/post_ad.html', context)


def pay(request, context):
    ad = get_object_or_404(AdvertisePost, hash=context['hash'])
    amount = ad.total_price * 100

    # Set your secret key: remember to change this to your live secret key in production
    # See your keys here: https://dashboard.stripe.com/account/apikeys
    stripe.api_key = "sk_test_exhH8mdKfkXkaxzvtVphJOBZ"

    # Token is created using Checkout or Elements!
    # Get the payment token ID submitted by the form:
    if request.POST.get('stripeToken'):
        print(request.POST)
        token = request.POST.get('stripeToken')

        charge = stripe.Charge.create(
            amount=amount,
            currency='usd',
            description='Boosted Post',
            source=token,
        )
        print('Charge:', charge)
        return HttpResponseRedirect('/')
    else:
        print(request.POST)
        print('NO')

    context = {
        'amount': amount,
        'ad': ad
    }

    return render(request, 'advertising/pay.html', context)

知道为什么会这样，以及如何解决它？

如果你好奇，这是条纹形式：

<form action="" method="POST">{% csrf_token %}
  <script
    src="https://checkout.stripe.com/checkout.js" class="stripe-button"
    data-key="pk_test_8rSK77eA02iovefCmQCeV9su"
    data-amount="{{ amount }}"
    data-name="My name"
    data-description="Example charge"
    data-image="https://stripe.com/img/documentation/checkout/marketplace.png"
    data-locale="auto"
    data-currency="aud">
  </script>
</form>
