我想用JSON.NET替换默认的WCF JSON(适用于所有数据类型)序列化。 我在网上搜索过,找不到合适的解决方案。
这是我的目标:
[JsonObject]
public class TestObject
{
[JsonProperty("JsonNetName")]
public string Name = "John";
[JsonProperty]
public DateTime Date = DateTime.Now;
}
这是我的WCF功能:
[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
List<TestObject> Get();
这是Global.asax中的代码:
protected void Application_Start(object sender, EventArgs e)
{
// Create Json.Net formatter serializing DateTime using the ISO 8601 format
var serializerSettings = new JsonSerializerSettings();
serializerSettings.Converters.Add(new IsoDateTimeConverter());
serializerSettings.Converters.Add(new BinaryConverter());
serializerSettings.Converters.Add(new JavaScriptDateTimeConverter());
serializerSettings.Converters.Add(new BinaryConverter());
serializerSettings.Converters.Add(new StringEnumConverter());
var config = HttpHostConfiguration.Create().Configuration;
Microsoft.ApplicationServer.Http.JsonMediaTypeFormatter jsonFormatter = config.OperationHandlerFactory.Formatters.JsonFormatter;
config.OperationHandlerFactory.Formatters.Remove(jsonFormatter);
config.OperationHandlerFactory.Formatters.Insert(0, new JsonNetMediaTypeFormatter(serializerSettings));
var httpServiceFactory = new HttpServiceHostFactory
{
OperationHandlerFactory = config.OperationHandlerFactory,
MessageHandlerFactory = config.MessageHandlerFactory
};
//Routing
RouteTable.Routes.Add(
new ServiceRoute(
"Brands", httpServiceFactory,
typeof(Brands)));
}
这是Web.Config:
<endpointBehaviors>
<behavior name="Behavior_Brands">
<webHttp defaultOutgoingResponseFormat="Json" defaultBodyStyle="Bare" />
</behavior>
</endpointBehaviors>
和服务部分:
<service name="TestApp.CoreWCF.Brands">
<endpoint address="" behaviorConfiguration="Behavior_Brands" binding="webHttpBinding" contract="TestApp.CoreWCF.IBrands">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</service>
最后,这是我在启动网址时所得到的:
“http://localhost:30000/Brands/Get”
[{"Date":"\/Date(1354364412708+0200)\/","Name":"John"}, {"Date":"\/Date(1354364412708+0200)\/","Name":"John"}]
JSON答案显然忽略了JSON.NET属性。
答案 0 :(得分:18)
无论如何,我想出了一种方法来手动使用不同的串行器,它看起来效率更高,速度更快,因为它没有通过微软的串行器,虽然代码方面它有点麻烦。
在接口和实现它们的类中将所有返回类型设置为“System.ServiceModel.Channels.Message”。
[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
System.ServiceModel.Channels.Message GetData();
创建一个扩展方法,以便您可以使用JSON.NET序列化程序(或您想要使用的任何一个)轻松地从对象构建内存流。
public static System.ServiceModel.Channels.Message GetJsonStream(this object obj)
{
//Serialize JSON.NET
string jsonSerialized = JsonConvert.SerializeObject(obj);
//Create memory stream
MemoryStream memoryStream = new MemoryStream(new UTF8Encoding().GetBytes(jsonSerialized));
//Set position to 0
memoryStream.Position = 0;
//return Message
return WebOperationContext.Current.CreateStreamResponse(memoryStream, "application/json");
}
在方法的主体中,将序列化的对象直接返回到流
return yourObject.GetJsonStream();
