Identity Server 4 未向控制器返回错误描述

我有一个 Identity server 4 项目，它遵循有关如何显示错误的文档

家庭控制器：

public class HomeController : Controller
{
    private readonly IIdentityServerInteractionService _interaction;

    public HomeController(IIdentityServerInteractionService interaction)
    {
        _interaction = interaction;
    }

    public IActionResult Index()
    {
        return View();
    }

    public async Task<IActionResult> Error(string errorId)
    {
        var vm = new ErrorViewModel();
        var message = await _interaction.GetErrorContextAsync(errorId);
        if (message != null)
            vm.Error = message;
        return View("Error", vm);
    }
}

身份服务器本身在日志中提供了一些有用的信息

      }

and

      }

但是，唯一的信息不会返回给我的控制器GetErrorContextAsync因此只能向用户显示错误名称。

错误的描述根本没有填写。

我如何获得至少填充的描述？

我正在寻找一种为这里的开发人员显示一些明智信息的方法。然而，每个错误都会返回 unauthorized_client，所以我无法告诉开发人员这是重定向 URI 与无效客户端 ID 的问题。

if (vm.Error.Error == "unauthorized_client") vm.Error.ErrorDescription = "Contact plugin developer.";

注意：重定向 URI 似乎确实返回描述。

这是设计的目的。您无法访问原因unathorized_client在你的控制器中。

您还可以检查来源以了解发生了什么。

//////////////////////////////////////////////////////////
// check for valid client
//////////////////////////////////////////////////////////
var client = await _clients.FindEnabledClientByIdAsync(request.ClientId);
if (client == null)
{
    LogError("Unknown client or not enabled", request.ClientId, request);
    return Invalid(request, OidcConstants.AuthorizeErrors.UnauthorizedClient);
}
