如何使用 ASP.NET 核心将试用添加到条带结帐

Question

使用 stripe checkout 向 asp core 3.1 添加试用版的语法是什么？我正在尝试将 TrialPeriodDays 分配给 SubscriptionData 以进行 7 天免费试用。

// Checkout Session
var options = new SessionCreateOptions
                  {
                      LineItems = new List<SessionLineItemOptions>
                                  {
                                      new SessionLineItemOptions
                                          {
                                              Price = "price_1KJSMXC...",
                                              Quantity = 1,
                                          },
                                  },
                      // I believe I need to assign the trial to SubscriptionData below
                      SubscriptionData = { },           
                      Mode = "subscription",

                      SuccessUrl = "https://example.com/Success",
                      CancelUrl = "https://example.com/Cancel",
                  };

SubscriptionData = new Stripe.Checkout.SessionSubscriptionDataOptions
{
  TrialPeriodDays = 7
},
Mode = "subscription",
