c# - 将带有 NodaTime 自动 Prop 的模型发布到 WebAPI

我们正在将 NodaTime 用于我们项目中的时间/日期模型。该项目是一个 Web 应用程序，使用 WebAPI。当尝试发布包含 LocalTime 自动 Prop 的模型时，我们收到 InsufficientExecutionStackException。

为了将我们的项目与这个问题隔离开来，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)ValuesController.cs 文件中，我劫持了 Post 如下:

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

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

发布此输入模型时(通过 postman )，而不是接收本地时间，我在本文末尾收到错误。

如果我们按照所示重写 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;
}

我可以做些什么来让应用程序与 autoprops 一起工作？虽然我可以(并且可能会)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 行任意行:

最佳答案

这似乎是一个 WebAPI 问题，但我并不完全了解根本原因，也不是我特别喜欢这个解决方案。但是，基于 the code in this answer ，我想出了一个解决方法:

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 配置的任何地方:

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

在我(或其他人)找到更好的解决方案之前，请将此视为一种变通方法。谢谢。

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