根据json值路由到不同的操作

Mat*_*ser 4 c# asp.net-web-api asp.net-web-api-routing

我想根据特定json参数的值将请求路由到不同的操作.

例如,给定以下json数据:

{
  type: "type1",
  type1data: "type1value"
}

{
  type: "type2",
  type2data: "type2value"
}

我希望能在我的ApiController上有两个不同的动作:

void CreateType1(string type1data) 
{ 
  // ... 
}

void CreateType2(string type2data) 
{ 
  //... 
}

这样的事情怎么办?

更新:

如果可能,我想要相同的网址.有点像/objects/create.

我宁愿使用自定义的ApiControllerActionSelector.

public class MyActionSelector : ApiControllerActionSelector
{
    public override HttpActionDescriptor SelectAction(
                                HttpControllerContext context)
    {
        HttpMessageContent requestContent = new HttpMessageContent(
                                                           context.Request);
        var json = requestContent.HttpRequestMessage.Content
                                .ReadAsStringAsync().Result;
        string type = (string)JObject.Parse(json)["type"];

        var actionMethod = context.ControllerDescriptor.ControllerType
            .GetMethods(BindingFlags.Instance | BindingFlags.Public)
            .FirstOrDefault(m => m.Name == "Create" + type);

        if (actionMethod != null)
        {
            return new ReflectedHttpActionDescriptor(
                               context.ControllerDescriptor, actionMethod);
        }

        return base.SelectAction(context);
    }
}

这是模型.我给了它一个奇怪的名字Abc.

public class Abc
{
    public string Type { get; set; }
    public string Type1Data { get; set; }
}

这是动作方法.

public void Createtype1(Abc a)
{

}

最后,插入动作选择器.

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

        config.Services.Replace(typeof(IHttpActionSelector),
                                    new MyActionSelector());
    }
}

如果现在POST到http:// localhost:port/api/yourapicontroller,则根据JSON中类型字段中的值,将选择操作方法Create*.
