Asp.net POST方法无法在ServiceStack中填充请求对象

我使用服务堆栈已经有一段时间了，遇到了一个场景，POST方法使用IReturn对象的默认实例（所有属性都默认为其数据类型值）。作为路由的一部分提供的值（/product/1234345/）是唯一填充的值。我在下面列出了一个例子：

[Route("/search/{searchMethod}/books")]
public class SearchRequest : IReturn<SearchResponse>
{
    public SearchProvider searchProvider { get; set; }

    public string searchTerm { get; set; }

    public string categoryID { get; set; }

    public long maxResults { get; set; }

    //Only this property gets populated if method is post
    public string searchMethod { get; set; }
}

public SearchResponse Any(SearchRequest searchRequest)
{
    //This works only for non-post requests
    return Put(searchRequest);
}

public SearchResponse Get(SearchRequest searchRequest)
{
    //This works
    return Put(searchRequest);
}

public SearchResponse Post(SearchRequest searchRequest)
{
    //This does not
    return Put(searchRequest);
}

public SearchResponse Put(SearchRequest searchRequest)
{
    //Code for put method goes here            
}

非常感谢您的帮助

谢谢

我总是在构造函数中填充我的请求对象并将其发送到服务

    searchClient.Post(new SearchRequest(SearchProvider.SampleSearchProvider, 
                                       searchterm, categoryID, 100,"conservative")):

在修补DTO之后，我终于找到了解决方案。对于post请求，似乎所有DTO属性都需要有一个[DataMember]属性来进行序列化/反序列化，并确保类也有一个[DataContract]属性。

听起来不对，SearchServiceClient使用的序列化程序是什么？它是否继承现有ServiceStack ServiceClient？如果是JSON，则

[DataContract]

和

[DataMember]

attrs使序列化选择在何处。

    searchClient.Post(new SearchRequest(SearchProvider.SampleSearchProvider, 
                                       searchterm, categoryID, 100,"conservative")):
