配置JsonNetSerializer使用南希TinyIoC JsonNetBodyDeserializer [英] Configuring JsonNetSerializer and JsonNetBodyDeserializer using Nancy TinyIoC
问题描述
我是一个小白南希。我一直在使用它作为一个框架，以产生一个REST API。我所熟悉的Json.NET，所以我一直在玩的 Nancy.Serialization.JsonNet 包。
I am a noob to Nancy. I have been using it as a framework to produce a REST API. I am familiar with Json.NET so I've been playing with the Nancy.Serialization.JsonNet package.
我的目标：自定义行为（即更改设置）的 JsonNetSerializer 和 JsonNetBodyDeserializer
My goal: to customize the behavior (i.e. change the settings) of the JsonNetSerializer and JsonNetBodyDeserializer.
我特别想包含以下设置...
Specifically I'd like to incorporate the following settings...
var settings = new JsonSerializerSettings { Formatting = Formatting.Indented };
settings.Converters.Add( new StringEnumConverter { AllowIntegerValues = false, CamelCaseText = true } );
我想使用内建的TinyIoC容器内，避免继承链，并限制所产生的潜在问题来执行此定制从 Nancy.Serialization.JsonNet 包中的任何变化。
的注：作为暂时的解决办法，我已经利用继承来创建 CustomJsonNetSerializer 和 CustomJsonNetBodyDeserializer 。的
我曾尝试几种方法来至少将这一配置的 JsonNetSerializer 。我还没有尝试配置 JsonNetBodyDeserializer 使用TinyIoC呢。我想它会同样进行。所有我尝试过的工作是在我的 CustomNancyBootstrapper 。
I have tried several approaches to incorporate this configuration at least for the JsonNetSerializer. I've not tried configuring the JsonNetBodyDeserializer using the TinyIoC yet. I imagine it will be done similarly. All the work I've tried is in my CustomNancyBootstrapper (which inherits from DefaultNancyBootstrapper).
最成功的方法至今：覆盖 ConfigureApplicationContainer
Most successful approach so far: override ConfigureApplicationContainer
protected override void ConfigureApplicationContainer( TinyIoCContainer container )
{
base.ConfigureApplicationContainer( container );
// probably don't need both registrations, and I've tried only keeping one or the other
var settings = new JsonSerializerSettings { Formatting = Formatting.Indented };
settings.Converters.Add( new StringEnumConverter { AllowIntegerValues = false, CamelCaseText = true } );
container.Register( new JsonNetSerializer( JsonSerializer.CreateDefault( settings ) ) );
container.Register<ISerializer>( new JsonNetSerializer( JsonSerializer.CreateDefault( settings ) ) );
}
我已经追踪代码，并观看了 JsonNetSerializer（ 。JsonSerializer串行）在JsonNet包构造
潜在的问题：我注意到构造函数被调用两次。没想到这一行为。
Potential problem: I noticed the constructor is called twice. I did not expect this behavior.
第一次一切都刚刚好 - 我的定制添加和正确注册。但是，则第二时间发生和类型都重新登记，没有设置的定制。重新注册出现，以取代原登记失去了我的设置，自定义设置。
The first time everything is just right - my customization is added and registered properly. But, then the second time happens and the types are re-registered, without the settings customization. The re-registration appears to replace the original registration losing my settings customization.
调用堆栈中的第二次调用构造函数表明，它在<$ C $称为C> GetEngine 和 GetEngineInternal 这似乎试图建立一个 NancyEngine （我用自主机包，以便这种情况发生在Program.cs中 - 使用（VAR主机=新NancyHost（URI）））
The call stack the second time the constructor is called shows that it is called during GetEngine and GetEngineInternal which seems to try to build a NancyEngine (I am using the self-host package so this happens in program.cs -- using(var host = new NancyHost(uri)) ).
好像我不是要告诉南希不要做某件事，或者我需要挂钩到链中稍后的一部分。
Seems like I either need to tell Nancy not to do something or I need to hook in to a later part in the chain.
任何帮助将是。欣赏
推荐答案
一般来说，在南希来解决这个问题的方法是实现自己的JSON序列化，像这样：
Typically the way to solve this in Nancy is to implement your own JSON Serializer like so:
public sealed class CustomJsonSerializer : JsonSerializer
{
public CustomJsonSerializer()
{
ContractResolver = new CamelCasePropertyNamesContractResolver();
Converters.Add(new StringEnumConverter
{
AllowIntegerValues = false,
CamelCaseText = true
});
Formatting = Formatting.Indented;
}
}
在这里，您可以覆盖所有设置。
Here you can override all the settings.
然后你可以使用 IRegistrations
public class JsonRegistration : IRegistrations
{
public IEnumerable<TypeRegistration> TypeRegistrations
{
get
{
yield return new TypeRegistration(typeof(JsonSerializer), typeof(CustomJsonSerializer));
}
}
public IEnumerable<CollectionTypeRegistration> CollectionTypeRegistrations { get; protected set; }
public IEnumerable<InstanceRegistration> InstanceRegistrations { get; protected set; }
}
问： 如何做到这一点办法从创建CustomJsonNetSerializer从JsonNetSerializer继承，然后在ConfigureApplicationContainer（container.Register（typeof运算（JsonNetSerializer）的typeof（CustomJsonNetSerializer））注册它有什么不同？的
< STRONG>答：的JsonSerializer是执行，如果json.net南希，这是我们定义在GitHub上的自述推荐的方法：
A: The JsonSerializer is the implementation if json.net for Nancy, this is the recommended method we define on the readme on github:
<一个HREF =https://github.com/NancyFx/Nancy.Serialization.JsonNet#customization> https://github.com/NancyFx/Nancy.Serialization.JsonNet#customization
你提到的类是对象到JSON的序列化，还有一个负责处理反序列化，这两者利用JsonSerializer内部：
The class you mention is the serialization of an object to JSON, there is another which handles deserialization, both of which utilize JsonSerializer internally:
使用这种方法使执行设置保持一致任何地方，该JsonSerializer被使用。
Using this method makes the implementation settings consistent anywhere that the JsonSerializer is used.
问： 我能正确地从你介绍，我将不再需要在明确注册CustomJsonSerializer的做法推断？ConfigureApplicationContainer覆盖在我的CustomNancyBootstrapper 的
答：我已经登记完成的方法只是用于注册依赖清洁抽象，而不是使一个巨大的引导程序，你可以创建一个小一些特定的类。
A: The method I've done for registering is just a cleaner abstraction for registering dependencies, rather than making one giant Bootstrapper, you can create a few smaller specific classes.
使用我的方法是意味着你不需要引导程序进行注册。
Yes using my method means you do not need to register in the bootstrapper.
