Backbone.js的WCF Rest Post始终在服务器上接收空对象

Question

我正在使用backbone.js并将模型（todo）发布到wcf Rest服务，其详细信息可在下面找到。由于某种原因，无论发布的json如何，实现总是会收到一个空值。

合同

    [WebInvoke(ResponseFormat = WebMessageFormat.Json, Method = "POST", UriTemplate = "Todos", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    [OperationContract]
    Wallet CreateTodos(Todo instance);

实施

    public Wallet CreateTodos(Todo instance)
    {
        if (instance == null)
        {
            WebOperationContext.Current.OutgoingResponse.StatusCode = HttpStatusCode.NotAcceptable;
            return null;
        }

      ... blah blah blah

数据合同

[DataContract]
Public Class Todo
{    
  [DataMember]
  public string Name{get;set;}    
}

发布Json

{   “名字”：“欢迎客人” }
