如何在WCF DataService中接受JSON？

如何在WCF DataService中接受JSON？

将参数添加到您的方法。您还需要WebInvoke上的一些其他属性。

这是一个示例（从内存来看，可能会有些偏离）

[WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "modifyMyPerson")]public void Modify(Person person) {   ...}

对于人员类，如下所示：

[DataContract]public class Person {[DataMember(Order = 0)]public string FirstName { get; set; }}

和json这样发送

var person = {FirstName: "Anthony"};var jsonString = JSON.stringify({person: person});// Then send this string in post using whatever, I personally use jQuery

编辑：这是使用“包装”的方法。如果没有包装方法，您将取出

BodyStyle =...

并对其进行字符串化，就可以了

JSON.stringify(person)

。如果需要添加其他参数，我通常只使用包装方法。

编辑完整代码示例

Global.asax

using System;using System.ServiceModel.Activation;using System.Web;using System.Web.Routing;namespace MyNamespace{    public class Global : HttpApplication    {        protected void Application_Start(object sender, EventArgs e)        { RouteTable.Routes.Add(new ServiceRoute("myservice", new WebServiceHostFactory(), typeof(MyService)));        }    }}

Service.cs

using System;using System.ServiceModel;using System.ServiceModel.Activation;using System.ServiceModel.Web;namespace MyNamespace{    [ServiceContract]    [ServiceBehavior(MaxItemsInObjectGraph = int.MaxValue)]    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]    public class MyService    {        [OperationContract]        [WebInvoke(UriTemplate = "addObject", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]        public void AddObject(MyObject myObject)        { // ...        }        [OperationContract]        [WebInvoke(UriTemplate = "updateObject", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]        public void UpdateObject(MyObject myObject)        { // ...        }        [OperationContract]        [WebInvoke(UriTemplate = "deleteObject", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]        public void DeleteObject(Guid myObjectId)        { // ...        }    }}

并将其添加到

Web.config

  <system.serviceModel>    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />  </system.serviceModel>
