ServiceStack：在DTO中使用屬性來設置響應頭和響應主體

我正在使用servicestack和AngularJS資源模塊。問題是，當我調用我的服務的query（）方法來請求一個分頁列表時，我想發送一個自定義的響應標題和行數。ServiceStack：在DTO中使用屬性來設置響應頭和響應主體

我想HTTP響應看起來像這樣：

HTTP/1.1 200 OK 
Content-Type: application/json; charset=utf-8 
Server: Microsoft-IIS/8.0 
X-Total-Rows: 14 
X-Powered-By: ServiceStack/3,958 Win32NT/.NET 
Content-Length: 831 

[{"id":11,"content":"Item 10","dueDate":"2013-10-17T00:00:00.0000000","priority":9}, 
{"id":13,"content":"Item 12","dueDate":"2013-06-16T00:00:00.0000000","priority":9}, 
{"id":20,"content":"Item 19","dueDate":"2013-04-06T00:00:00.0000000","priority":9}, 
{"id":32,"content":"Item 31","dueDate":"2013-01-21T00:00:00.0000000","priority":9}, 
{"id":42,"content":"Item 41","dueDate":"2013-05-16T00:00:00.0000000","priority":9}, 
{"id":19,"content":"Item 18","dueDate":"2013-07-14T00:00:00.0000000","priority":8}, 
{"id":15,"content":"Item 14","dueDate":"2013-03-06T00:00:00.0000000","priority":7}, 
{"id":12,"content":"Item 11","dueDate":"2013-02-23T00:00:00.0000000","priority":4}, 
{"id":18,"content":"Item 17","dueDate":"2013-10-21T00:00:00.0000000","priority":3}, 
{"id":14,"content":"Item 13","dueDate":"2013-01-11T00:00:00.0000000","priority":2}]

就目前而言，要做到這一點，我用下面的DTO：

[Route("/todos", Verbs = "GET")] 
public class Todos : IReturn<List<Todo>> 
{ 
    [DataMember(Name = "q")] public string Query { get; set; } 
    [DataMember(Name = "sort")] public string Sort { get; set; } 
    [DataMember(Name = "desc")] public bool IsDesc { get; set; } 
    [DataMember(Name = "limit")] public int? Limit { get; set; } 
    [DataMember(Name = "offset")] public int Offset { get; set; } 
} 

[Route("/todos", Verbs = "POST")] 
[Route("/todos/{Id}", Verbs = "GET,PUT,DELETE")] 
public class Todo : IReturn<Todo> 
{ 
    public int Id { get; set; } 
    public string Content { get; set; } 
    public DateTime? DueDate { get; set; } 
    public int? Priority { get; set; } 
}

而且在服務：

public object Get(Todos request) 
{ 
    long count; 
    var items = _repository.GetAll(request.Query, request.Sort, request.IsDesc, request.Limit, request.Offset, out count); 
    Response.AddHeader("X-Total-Rows", count.ToString(CultureInfo.InvariantCulture)); 
    return items.Select(Mapper.Map<TodoItem, Todo>).ToList(); 
}

我想在服務棧中做的是在ResponseDTO中使用自定義屬性來表明我想要一些要在響應頭中序列化的屬性以及在響應主體中序列化的其他屬性。響應DTO可能是這樣的：

public class TodosResponse 
{ 
    [Header(Name = "X-Total-Rows")] public int TotalRows { get; set; } 
    [Body] public List<Todo> Todos { get; set; } 
}

服務將創造這樣的迴應：

public object Get(Todos request) 
{ 
    long count; 
    var items = _repository.GetAll(request.Query, request.Sort, request.IsDesc, request.Limit, request.Offset, out count); 
    return new TodosResponse 
      { 
       TotalRows = count, 
       Todos = items.Select(Mapper.Map<TodoItem, Todo>).ToList() 
      }; 
}

和當然，HTTP響應會是什麼樣子完全同上。

所以我的問題是：是否有可能實現這與自定義屬性？

實現你想要的更簡單/更整潔的方法是返回一個HttpResult並在其中定義頭文件。

public object Get(Todos request) 
{ 
    long count; 
    var items = _repository.GetAll(request.Query, request.Sort, request.IsDesc, request.Limit, request.Offset, out count); 
    var response = items.Select(Mapper.Map<TodoItem, Todo>).ToList(); 

    return new HttpResult(response, HttpStatusCode.OK) 
      { 
       Headers = 
         { 
          {"X-Total-Rows", count} 
         } 
      }; 
}

這避免了與元數據

污染的響應對象
