【中文标题】Stripe - 单一方法预构建 UI，STPAPIClient.shared().publishableKey iOS Swift UiKit【英文标题】：Stripe - single method prebuit UI, STPAPIClient.shared().publishableKey iOS Swift UiKit 【发布时间】：2021-10-31 20:24:14 【问题描述】：

我关注了这个文档：https://stripe.com/docs/payments/accept-a-payment?platform=ios&ui=payment-sheet

我从我的后端获取这些。

"clientSecret" : "pi_3JUrPkLW44AR......7WElFl", "stripecustomerid" : "cus_K8......pLu4", “paymentids”：“pi_3JVA .....R9VmA” "EphemeralKey" : "ephkey_1JV......kEtnlw"

//PaymentSheet Configuration

 let clientSecret = response["clientSecret"].stringValue            
 let ephemeralSecret = response["EphemeralKey"].stringValue
 let cusId = response["stripecustomerid"].stringValue

 // MARK: Set your Stripe publishable key - this allows the SDK to make requests to Stripe for your account

    STPAPIClient.shared.publishableKey = self.publishableKey

 // MARK: Create a PaymentSheet instance
    var configuration = PaymentSheet.Configuration()
    configuration.merchantDisplayName = "Z*****"
    configuration.customer = .init( id: cusId, ephemeralKeySecret: ephemeralSecret)
    configuration.returnURL = "payments-example://stripe-redirect"
    self.paymentSheet = PaymentSheet(
                    paymentIntentClientSecret: clientSecret,
                    configuration: configuration)

在此之后（付款开始）我从条带获取日志：

日志分析：[“product_usage”：[“PaymentSheet”]，“app_name”：“Zucraz”，“additional_info”：[]，“bindings_version”：“21.8.1”，“apple_pay_enabled”：0，“ocr_type “：“无”，“os_version”：“14.4”，“analytics_ua”：“analytics.stripeios-1.0”，“ui_usage_level”：“部分”，“publishable_key”：“pk_test_51J9Te0LW............tRQbRP2 ", "device_type": "iPhone12,1", "event": "mc_complete_init_customer", "app_version": "3.4"]

调用此方法时 - 显示 PaymentSheet

func openPaymentSheet()
        // MARK: Start the checkout process
        paymentSheet?.present(from: self)  paymentResult in
            // MARK: Handle the payment result
            switch paymentResult 
            case .completed:
                self.displayAlert("Your order is confirmed!")
            case .canceled:
                print("Canceled!")
            case .failed(let error):
                print(error)
                self.displayAlert("Payment failed: \n\(error.localizedDescription)")

收到此错误

Error Domain=com.stripe.lib Code=50 "There was an unexpected error -- try again in a few seconds" UserInfo=NSLocalizedDescription=There was an unexpected error -- try again in a few seconds, com.stripe.lib:ErrorMessageKey=No valid API key provided. Set `STPAPIClient.shared().publishableKey` to your publishable key, which you can find here: https://stripe.com/docs/keys, com.stripe.lib:StripeErrorTypeKey=invalid_request_error, com.stripe.lib:StripeErrorCodeKey=

文档中没有定义设置 STPAPIClient.shared().publishableKey。仍然，我尝试在我的视图控制器中设置 STPAPIClient.shared.publishableKey，但仍然收到错误。

提前致谢

【问题讨论】：

如果您不设置临时密钥，也会出现该错误，不幸的是，该错误有点令人困惑。你能分享你的完整代码吗？包括实际解析服务器响应并使用客户详细信息创建PaymentSheet.Configuration() 的部分？嗨@karllekko 添加了支付配置代码。你能记录下例如的值吗？ ephemeralSecret 并确保它不是零？您还应该在使用时记录self.publishableKey，只需进行一些调试以检查这些变量是否意外地为零。也可能不相关，但您正在配置 self.paymentSheet 但稍后您将展示 paymentSheet ，因此由于它不引用 self 您可能有两个 PaymentSheet 变量实例并且只配置了其中一个？不看完整的代码很难说。 response["EphemeralKey"][0]["id"].stringValue 在我看来不合适。您不需要密钥的 ID，您需要从 API(stripe.com/docs/payments/…) 返回的对象的 secret 值。您拥有的值应该类似于 ek_test_xxx ，而不是 ephkey_xxx。 【参考方案1】：

不要对错误感到困惑：“将STPAPIClient.shared().publishableKey 设置为您的可发布密钥”。

与此无关。

如果遇到此类错误，请检查您的密钥。

EphemeralKey 必须类似于：ek_test_xxx（秘密）。
