c# - Web Api 服务器端处理和数据表参数

Question

我正在尝试创建一个对象来表示数据表提供给我的 Web API 调用的值，然后我会将其路由到另一个实际返回值的 API(以将数据表废话与 API 接口(interface)分开)。

在对数据表 wiki 进行了一些研究之后，我最终定义了以下对象:

public class DataTableParameters
{
    public int draw { get; set; }
    public int start { get; set; }
    public int length { get; set; }
    public order[] order { get; set; }
    public column[] columns { get; set; }
}

public class order
{
    public int column { get; set; }
    public string dir { get; set; }
}

public class column
{
    public string data { get; set; }
    public string name { get; set; }
    public bool searchable { get; set; }
    public bool orderable { get; set; }
    public search search { get; set; }
}

public class search
{
    public string value { get; set; }
    public bool regex { get; set; }
}

但是，当我尝试将它们用作 DataTables api Controller 的参数时，结果为空:

    public DataTableResult Get(DataTableParameters parameters) //parameters is null!
    {
         return new DataTableResult();
    }

据我了解，模型绑定(bind)应该是读取结果并将其应用于我的对象。这是从前端调用 api 的示例:

Key Value
Request GET /MVC/api/DataTables?action=Get&draw=1&columns%5B0%5D%5Bdata%5D=0&columns%5B0%5D%5Bname%5D=&columns%5B0%5D%5Bsearchable%5D=true&columns%5B0%5D%5Borderable%5D=true&columns%5B0%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B0%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B1%5D%5Bdata%5D=1&columns%5B1%5D%5Bname%5D=&columns%5B1%5D%5Bsearchable%5D=true&columns%5B1%5D%5Borderable%5D=true&columns%5B1%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B1%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B2%5D%5Bdata%5D=2&columns%5B2%5D%5Bname%5D=&columns%5B2%5D%5Bsearchable%5D=true&columns%5B2%5D%5Borderable%5D=true&columns%5B2%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B2%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B3%5D%5Bdata%5D=3&columns%5B3%5D%5Bname%5D=&columns%5B3%5D%5Bsearchable%5D=true&columns%5B3%5D%5Borderable%5D=true&columns%5B3%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B3%5D%5Bsearch%5D%5Bregex%5D=false&order%5B0%5D%5Bcolumn%5D=0&order%5B0%5D%5Bdir%5D=asc&start=0&length=10&search%5Bvalue%5D=&search%5Bregex%5D=false&_=1440437669357 HTTP/1.1

为什么我的参数对象为空，我该如何解决？

编辑:我也试过这个:

 public DataTableResult Get(int draw, int start, int length, column[] columns, order[] order)
    {
        return new DataTableResult();
    }

但我得到“无法将多个参数(‘列’和‘顺序’)绑定(bind)到请求的内容。”

UGH 不到 10 分钟后，我需要参数上的 [FromUri] 属性。

 public DataTableResult Get([FromUri]DataTableParameters parameters)
 {
      return new DataTableResult();
 }
