如何使用webinvoke方法(Post或PUT)在wcf rest中传递多个body参数

[ServiceContract]
public interface IMyService
{
    [OperationContract]
    [WebInvoke(Method = "POST", UriTemplate = "/myoperation")]
    void MyOperation(RequestData requestData);
}

[DataContract]
public class RequestData
{
    [DataMember]
    public string Parameter1 { get; set; }

    [DataMember]
    public string Parameter2 { get; set; }
}

public class MyService : IMyService
{
    public void MyOperation(RequestData requestData)
    {
        // 处理接收到的多个body参数
        string parameter1 = requestData.Parameter1;
        string parameter2 = requestData.Parameter2;

        // 执行相应的业务逻辑
        // ...
    }
}

<system.serviceModel>

{
  "Parameter1": "Value1",
  "Parameter2": "Value2"
}
