我正在使用 Stripe 支付网关进行电子商务交易。要进行交流，我必须使用 webhook url 意味着我将提供一个 url，以便他们可以与我们交流。
我创建了一个 Controller 和 Action，它是 [AllowAnonymus]。当我在本地运行应用程序并在浏览器上键入 Controller 和操作时，它会触发操作。但是当我部署在我的测试服务器上并执行相同的操作时，它会出现以下错误
Server Error in '/' Application. The device is not ready.

谁能帮我解决这个问题。
以下代码写在Action中:
public class StripeWebhookController : BaseController
{
//
// GET: /StripeWebhook/
[AllowAnonymous]
public JsonResult GetStripeResponse()
{
Stream req = Request.InputStream;
req.Seek(0, System.IO.SeekOrigin.Begin);
string json = new StreamReader(req).ReadToEnd();
DTO.OrderItem.SavePartialCharge(json);
return Json("", JsonRequestBehavior.AllowGet);
}
}
添加方法 SavePartialCharge
public static String SavePartialCharge(string invoiceData)
{
try
{
string stripeEventType = BL.PaymentGateway.StripeReturn.GetStripeType(invoiceData);
var obj = JObject.Parse(invoiceData);
var dataObj = obj.SelectToken("data.object");
var subscriptionID = dataObj.SelectToken("subscription").ToString();
var customerID = dataObj.SelectToken("customer").ToString();
var chargeID = dataObj.SelectToken("charge").ToString();
var amount = Convert.ToDecimal(!dataObj.SelectToken("subtotal").ToString().IsNullOrEmpty() ?dataObj.SelectToken("subtotal").ToString() : "0");
using (var db = new SchoolEntities())
{
switch (stripeEventType)
{
case "invoice.payment_failed":
var resultorderFailed =
db.OrderItems.Where(oi => oi.MerchantServiceSubscriptionID == subscriptionID)
.Select(oi => new {oi.ID, oi.Order.CreditCard4Digits})
.FirstOrDefault();
if (resultorderFailed != null)
OrderItemInstallment.AddOrderItemInstallment(db, resultorderFailed.ID, amount,
resultorderFailed.CreditCard4Digits, chargeID, false);
return "";
case "invoice.payment_succeeded":
var resultOrderSucceed =
db.OrderItems.Where(oi => oi.MerchantServiceSubscriptionID == subscriptionID)
.Select(oi => new {oi.ID, oi.Order.CreditCard4Digits, oi.TotalInstallments})
.FirstOrDefault();
if (resultOrderSucceed != null)
{
OrderItemInstallment.AddOrderItemInstallment(db, resultOrderSucceed.ID, amount,
resultOrderSucceed.CreditCard4Digits, chargeID, true);
var count =
db.OrderItemInstallments.Count(
oii => oii.OrderItemID == resultOrderSucceed.ID && oii.Success);
if (count == resultOrderSucceed.TotalInstallments)
BL.PaymentGateway.StripePaymentGateway.CancelSubscription(customerID,
subscriptionID);
}
return "";
}
}
}
catch (Exception ex)
{
System.IO.File.WriteAllText(@"D:\exception.txt", ex.Message);
}
return "";
}
最佳答案
您的 Stacktrace 指向 StreamWriter 的错误。根据您的代码，StreamWriter 只出现一次:
catch (Exception ex)
{
System.IO.File.WriteAllText(@"D:\exception.txt", ex.Message);
}
这意味着发生异常，您的 catch block 想要将此异常记录到您的本地驱动器。这会导致另一个异常，因为可能没有驱动器 D。 从逻辑上讲，在您解决了这个异常之后，还会有另一个异常，然后您的 catch block 将正确记录该异常。
检查您的测试机器，是否存在驱动器 D(并且它不是 CD 驱动器)并且您的 IIS 用户帐户具有适当的权限。
旁注:我不会以这种方式捕获异常。这只会用错误消息污染文本文件，没有堆栈跟踪、时间戳等。 您可以利用现有的许多日志记录框架之一(例如 NLOG)，让您的生活更轻松。
