如何将带有ajax的Json对象发送到ODataController

Question

我有一个OData服务，我想向它发送一个Json对象。但我不明白！

这是我的代码：

在MVC控制器中

public class SyncController : ODataController
{
 [HttpPost]
  public IQueryable<AppWriteError> GetSync(AppSyncDataModel data)
  {
    // do some stuff
  }
}

这是AppSyncDataModel：

public class AppSyncDataModel
{
    public Guid UserId { get; set; }
}

这是我的ajax电话：

$.ajax({
    url: url,
    type: "POST",
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    data: JSON.stringify(synchData) ,
    success: function () {
        alert("success :-)");
    },
    error: function () {
        alert("fail :-(");
    }

因此，如果我运行它，AppSynchDataModel始终为null，我收到以下消息：

{
  "odata.error":{
    "code":"","message":{
      "lang":"en-US","value":"No HTTP resource was found that matches the request URI 'http://localhost:3367/odata/Sync'."
    },"innererror":{
      "message":"No routing convention was found to select an action for the OData path with template '~/entityset'.","type":"","stacktrace":""
    }
  }
}

我该怎么做？
