发票人 PDF 给出 null 但会员资格不给出 PDF null

Question

我现在的问题。这是我必须使客户可以购买只支付一次的物品。因此将 Invoice id 和 PDf 分配给数据库。

现在我只能在 PDF 为空时获取发票 ID。

我已经阅读了更多关于此的内容。 Invoice Id return with null after change using Stripe

var options = new ProductCreateOptions
{
    Name = "Starter Setup",
};

var service = new ProductService();
var product = service.Create(options);

var optionsA = new PriceCreateOptions
{
    Product = product.Id,
    UnitAmount = 2000,
    Currency = "usd",
};

var serviceA = new PriceService();
var price = serviceA.Create(optionsA);

var optionsB = new CustomerCreateOptions
{
    Email = model.Mail,
    Name = model.FuldName,
    Source = token
};

var serviceB = new CustomerService();
var customer = serviceB.Create(optionsB);

var optionsC = new InvoiceItemCreateOptions
{
    Customer = customer.Id,
    Price = price.Id,
};

var serviceC = new InvoiceItemService();
var invoiceItem = serviceC.Create(optionsC);

var invoiceId = invoiceItem.Id;

var serviceE = new InvoiceService();
var f = serviceE.Get(invoiceId);

var pdf = f.InvoicePdf;// This here gives zero.

如果我这样做，我会解决这个问题。我在这里得到了我想要的发票 ID，但发票上没有显示它为零。

{
"id": "ii_1IR4UtFnB7TvDVRrzPwWo8ZW",
  "object": "invoiceitem",
  "amount": 2000,
  "currency": "usd",
  "customer": "cus_J3Aqpyt4PwqCcN",
  "date": 1614815575,
  "description": "Starter Setup",
  "discountable": true,
  "discounts": [
  ],
  "invoice": null,
  "livemode": false,
  "metadata": {
  },
....
}

有了这个，我的想法是我是否能够以某种方式使我成为会员，然后立即停止，但发票上说购买的只是一件物品，而不是几个月。

我这样做的方式与我这样做的会员资格有关。

var createCustomer = new CustomerCreateOptions
{
    Source = token,
    Name = model.FuldName,
    Email = model.Mail
};

var addService = new CustomerService();
var customer = addService.Create(createCustomer);

var optionsProduct = new ProductCreateOptions
{
    Name = $"Single buy - {DateTime.Now} - Kursus Id : {id}",
    Type = "service",
};
var serviceProduct = new ProductService();
Product product = serviceProduct.Create(optionsProduct);

var optionsPlan = new PlanCreateOptions
{
    Currency = "dkk",
    Interval = Helpers.Stripe.interval,
    Nickname =
        $"Single buy - {DateTime.Now} - Kursus Id : {id}",
    Amount = amount,
    Product = product.Id,
    IntervalCount = 1
};
var servicePlan = new PlanService();
Plan plan = servicePlan.Create(optionsPlan);

var items = new List<SubscriptionItemOptions>()
{
    new SubscriptionItemOptions()
    {
        Plan = plan.Id,
        Quantity = 1
    },
};
var createSubscruptionA = new SubscriptionCreateOptions
{
    Customer = customer.Id,
    Items = items,
    OffSession = true,
};
var addserviceA = new SubscriptionService();
Subscription subscription = addserviceA.Create(createSubscruptionA);

var invoiceId = subscription.LatestInvoiceId;
var service = new InvoiceService();
var pdf = service.Get(invoiceId).InvoicePdf;

我想通过这个实现的。我可以获取 PDF 和 Invoice id，因为我将来会在我的系统中使用它等。

var optionsB = new CustomerCreateOptions
{
    Email = model.Mail,
    Name = model.FuldName,
    Source = token
};

var serviceB = new CustomerService();
var customer = serviceB.Create(optionsB);

var optionsC = new InvoiceItemCreateOptions
{
    Customer = customer.Id,
    Price = price.Id,
};

var serviceC = new InvoiceItemService();
var invoiceItem = serviceC.Create(optionsC);

var invoiceId = invoiceItem.Id;

var invoiceOptions = new InvoiceCreateOptions
{
    Customer = customer.Id,
    AutoAdvance = true,
};
var invoiceService = new InvoiceService();
var invoice = invoiceService.Create(invoiceOptions);

对于一次性发票，您需要为客户创建发票项目（正如您所做的那样），但重要的是，您需要 create an Invoice 包含这些项目。

此行不适合您要完成的工作：

var invoiceId = invoiceItem.Id;

相反，您需要按照上面链接的文档中所示创建发票：

var invoiceOptions = new InvoiceCreateOptions
{
  Customer = "cus_123",
  AutoAdvance = true,
};
var invoiceService = new InvoiceService();
var invoice = invoiceService.Create(invoiceOptions);

在您finalize 之后，Invoice 对象将有一个invoice_pdf URL (docs)。

var service = new InvoiceService();
service.FinalizeInvoice(
  "in_123"
);
