我安装了以下内容:
<package id="Nancy" version="1.4.2" targetFramework="net4" />
<package id="Nancy.Owin" version="1.4.1" targetFramework="net4" />
<package id="Nancy.Serialization.JsonNet" version="1.4.1" targetFramework="net4" />
<package id="Newtonsoft.Json" version="7.0.1" targetFramework="net4" />
<package id="Owin" version="1.0" targetFramework="net4" />
并且:
public sealed class Startup
{
public void Configuration(IAppBuilder app)
{
var options = new NancyOptions();
app.UseNancy(options);
}
}
public sealed class CustomJsonNetSerializer : JsonSerializer
{
public CustomJsonNetSerializer()
{
ContractResolver = new CamelCasePropertyNamesContractResolver();
DateFormatHandling = DateFormatHandling.IsoDateFormat;
Formatting = Formatting.Indented;
}
}
然后在我的Bootstrapper中:
protected override void ConfigureApplicationContainer(TinyIoCContainer container)
{
base.ConfigureApplicationContainer(container);
container.Register<JsonSerializer, CustomJsonNetSerializer>();
}
最后在路线上:
public sealed class ApiBase : NancyModule
{
public ApiBase() : base("api/")
{
Get["user/"] = o => Response.AsJson(new { Context.CurrentUser, Time = DateTime.UtcNow});
}
}
但是,在运行此应用程序时,CustomJsonNetSerializer从未实例化,看起来Nancy正在使用不同的实现,可能是ISerializer.
请注意我想知道为什么这个解决方案失败了,因为我遵循官方doc而不是做其他实现,即实现ISerializer.
任何的想法?
[更新]
我无法弄清楚出了什么问题所以我最终得到了:
public sealed class CustomJsonNetSerializer : JsonSerializer, ISerializer
{
public CustomJsonNetSerializer()
{
ContractResolver = new CamelCasePropertyNamesContractResolver();
DateFormatHandling = DateFormatHandling.IsoDateFormat;
Formatting = Formatting.None;
}
public bool CanSerialize(string contentType)
{
return contentType.Equals("application/json", StringComparison.OrdinalIgnoreCase);
}
public void Serialize<TModel>(string contentType, TModel model, Stream outputStream)
{
using (var streamWriter = new StreamWriter(outputStream))
using(var jsonWriter = new JsonTextWriter(streamWriter))
{
Serialize(jsonWriter, model);
}
}
public IEnumerable<string> Extensions { get { yield return "json"; } }
}
和:
protected override void ConfigureApplicationContainer(TinyIoCContainer container)
{
base.ConfigureApplicationContainer(container);
container.Register<ISerializer, CustomJsonNetSerializer>();
}
最佳答案 为什么您认为未使用自定义序列化程序?
我可以看到设置为CustomJsonNetSerializer的断点被命中.
响应包含格式正确的JSON文件:
{
"currentUser": null,
"time": "2015-11-29T15:01:55.4669533Z"
}
如果我更改DateFormatHandling
至
DateFormatHandling = DateFormatHandling.MicrosoftDateFormat;
变更将按预期反映:
{
"currentUser": null,
"time": "\/Date(1448809002853)\/"
}
你能确保你的应用程序配置正确:
您的应用程序的根命名空间中有Startup类(是OWIN吗?).使用OwinStartup批注注释Startup类.就像是:
[组件:OwinStartup(typeof运算(WebApplication3.Startup))]
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.UseNancy();
}
}
你只有一个Bootstrapper
public class Bootstrapper : DefaultNancyBootstrapper
{
protected override void ConfigureApplicationContainer(TinyIoCContainer container)
{
base.ConfigureApplicationContainer(container);
container.Register<JsonSerializer, CustomJsonNetSerializer>();
}
}
