c# – 使用NodaTime自动道具向WebAPI发布模型

我们正在项目中使用NodaTime作为时间/日期模型.该项目是一个使用WebAPI的Web应用程序.尝试发布包含LocalTime autoprops的模型时,我们会收到InsufficientExecutionStackException.

为了将我们的项目与此问题隔离开来,我创建了一个新的WebAPI项目.使用NuGet,我将NodaTime和NodaTime.Serialization.JsonNet添加到项目中.在Startup.cs中,我使用了ConfigureForNodaTime：

GlobalConfiguration.Configure(x =>
{
    x.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
    x.Formatters.JsonFormatter.SerializerSettings.ConfigureForNodaTime(
    DateTimeZoneProviders.Tzdb);
});

在(样板文件)ValuesController.cs文件中,我这样劫持了Post：

// POST api/values
public void Post(TestClass input)
{
    var x = input;
}

public class TestClass
{
    public LocalTime Open { get; set; }
    public LocalTime Close { get; set; }
}

当发布此输入模型(通过邮递员),而不是接收本地时间时,我在本文末尾收到错误.

如果我们如图所示重写TestClass,则不会发生错误,并且我们得到正确的本地时间：

public class TestClass
{
    public LocalTime;
    public LocalTime;
}

我能做些什么来让应用程序与autoprops一起工作吗？虽然我可以(也可能会)开始用字段替换autoprops,但了解这里发生的事情会很好.

这是整个错误,从中间删除了800个任意行：

}

解决方法:

它似乎是一个WebAPI问题,但我不完全理解根本原因,我也不特别喜欢这个解决方案.但是,基于the code in this answer,我提出了一个解决方法：

public class CustomBodyModelValidator : DefaultBodyModelValidator
{
    public override bool ShouldValidateType(Type type)
    {
        return type.Namespace != "NodaTime" && base.ShouldValidateType(type);
    }
}

在您的配置lambda(或您访问全局WebAPI配置的任何位置：

x.Services.Replace(typeof(IBodyModelValidator), new CustomBodyModelValidator());

在我(或其他人)可以找到更好的解决方案之前,请考虑这是一种解决方法.谢谢.

更新：在进一步的研究中,它似乎已经作为issue #249发布到Noda Time问题跟踪器,并提出了类似的解决方案.
