如何根据 .NET 7 中的结果集中错误处理？

问：

我曾经在控制流中遇到异常，我可以轻松地编写一个中间件来将问题详细信息添加到响应中。但是现在我正在使用 FleuntResults，不知道如何实现以前的行为。

我想删除每个控制器操作的以下代码：

 if (result.IsFailed)
    {
        var errorMessage = result.Errors.FirstOrDefault()?.Message;

        var details = new ProblemDetails()
        {
            Status = StatusCodes.Status404NotFound,
            Title = "The specified resource was not found.",
            Type = "https://tools.ietf.org/html/rfc7231#section-6.5.4",
            Detail = errorMessage 
        };

        return NotFound(details);
    }

有异常的代码示例：

switch (exception)
    {
        case NotFoundException notFoundException:
            {
                context.Response.ContentType = "application/json";
                context.Response.StatusCode = (int)HttpStatusCode.NotFound;

                var response = new NotFoundResponseBody(notFoundException.Message);
                var payload = JsonSerializer.Serialize(response);
                return context.Response.WriteAsync(payload);
            }
        default:
            {
                context.Response.ContentType = "application/json";
                context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;

                var response = new { message = exception.Message };
                var payload = JsonSerializer.Serialize(response);
                return context.Response.WriteAsync(payload);
            }
    }
