ios - Stripe iOS : I'm not able to create charge using card id

Question

我正在尝试使用此处描述的标准 iOS 集成创建费用:https://stripe.com/docs/mobile/ios/standard

为此，我在 CheckoutController.swift 中有

func paymentContext(_ paymentContext: STPPaymentContext, didCreatePaymentResult paymentResult: STPPaymentResult, completion: @escaping STPErrorBlock) {

    StripeClient.shared.completeCharge(paymentResult, amount: 1000, shippingAddress: nil, shippingMethod: nil, completion: { (error: Error?) in
        if let error = error {
            completion(error)
        } else {
            completion(nil)
        }
    })
}

在我的 StripeClient.swift 中

func completeCharge(_ result: STPPaymentResult,
                    amount: Int,
                    shippingAddress: STPAddress?,
                    shippingMethod: PKShippingMethod?,
                    completion: @escaping STPErrorBlock) {
    let url = self.baseURL.appendingPathComponent("charge")

    var params: [String: Any] = [
        "source": result.source.stripeID,
        "amount": amount,
        "description": Purchase.shared.description()
    ]
    params["shipping"] = STPAddress.shippingInfoForCharge(with: shippingAddress, shippingMethod: shippingMethod)
    Alamofire.request(url, method: .post, parameters: params, headers: Credentials.headersDictionary())
        .validate(statusCode: 200..<300)
        .responseString { response in
            switch response.result {
            case .success:
                completion(nil)
            case .failure(let error):
                completion(error)
            }
    }
}

并且，在我的 API (Ruby on Rails) 中

  def charge
    Stripe::Charge.create(charge_params)
    render json: { success: true }, status: :ok
  rescue Stripe::StripeError => e
    render json: { error: "Error creating charge: #{e.message}" },
           status: :payment_required
  end

  private

  def charge_params
    params
      .permit(:amount, :description, :source)
      .merge(currency: 'gbp')
  end

问题出在 completeCharge 方法中，result.source.stripeID 正在返回卡 ID (card_xxxxxx)，但我需要一个 token (tok_xxxxxx)。所以，

如何从卡 ID 或 STPPaymentResult 对象中获取 token ？或者如何让我的 Rails API 使用卡 ID 代替 token ？或任何其他解决方案？

问候。

加油!当您使用 card_id 而不是 token 时，必须将客户 ID 作为参数传递，因此，我修改了我的 api:

  def charge_params
    params
      .permit(:amount, :description, :source)
      .merge(currency: 'gbp',
             customer: current_user.stripe_customer_id)
  end

(我将 Stripe 客户 ID 作为 stripe_customer_id 存储在我的用户表中)
