【问题描述】：

客户告诉我，连续使用网络30分钟后，弹出一个错误，说：

“发生错误！服务器未发送错误详细信息。”

我查了源码，发现应该是ticket.Properties.ExpiresUtc属性设置为30分钟造成的。 30分钟后如何自动刷新票？

30 分钟限制在 webapi/api/controllers/AccountController.cs 的 Authenticate 中。

堆栈跟踪如下：

【问题讨论】：

添加一个以 25 分钟为间隔的计时器。在每个滴答声中对其进行身份验证。

【解决方案1】：

SlidingExpiration 仅适用于 cookie： https://docs.microsoft.com/en-us/dotnet/api/system.web.configuration.formsauthenticationconfiguration.slidingexpiration?view=netframework-4.7.2

一般来说，accessToken的滑动过期是错误的——一旦accessToken被泄露，它可以被用来无限期地延长访问。这就是刷新令牌的用途。 ABP 不处理刷新令牌，但您可以参考 IdentityServer4 的Token Endpoint。请注意，刷新令牌也必须在客户端处理：当您收到 401 错误时，调用端点，然后设置为新的 accessToken。

如果您决定进行滑动过期，请参阅Reissusing a JWT with a New (Sliding) Expiration 上针对 WebApi 的第三方文档。
