I have controller which is

我有控制器

    [HttpGet]
    public IHttpActionResult GetUserRights(int id)
    {
        var rights = _rightsService.GetUserRights(id);
        if (rights == null)
        {
            return new HttpActionResult(HttpStatusCode.BadRequest, "User not found");
        }
        return Ok(rights);
    }

    [HttpPost]
    public IHttpActionResult SetUserRights(int id, IEnumerable<EditRightViewModel> rights)
    {
        Result result = _rightsService.SetUserRights(id, rights);
        if (!result.IsSuccess)
        {
            return new HttpActionResult(HttpStatusCode.InternalServerError, result.Message);
        }
        return Ok(result.Data);
    }

    [HttpPost]
    public IHttpActionResult SetUserRights(int id, int RightId, bool Enable)
    {
        Result result = _rightsService.SetUserRights(id, new List<EditRightViewModel>
        {
            new EditRightViewModel
            {
                RightId = RightId,
                Enable = Enable
            }
        });
        if (!result.IsSuccess)
        {
            return new HttpActionResult(HttpStatusCode.InternalServerError, result.Message);
        }
        return Ok(result.Data);
    }

The get request works fine but the post returns 404. The request is

get请求正常,但帖子返回404.请求是

User-Agent: Fiddler
Host: localhost:577
Content-Length: 44
Content-Type: application/json; charset=utf-8
{
"id":1,
"RightId":1,
"Enable":"true"
}

Originally I want to send data to the post action that has a list as parameter. I thought that reason why it returns 404 is that json doesn't fits the function's arguments. So I simplified json and action parameters but it still won't work. Maybe someone can tell what's the reason of the problem and how to write a correct json to send list as a parameter?

最初我想将数据发送到具有列表作为参数的post动作。我认为它返回404的原因是json不适合函数的参数。所以我简化了json和动作参数,但它仍然不起作用。也许有人可以告诉问题的原因是什么以及如何编写一个正确的json来发送列表作为参数?

404 Errors mostly occur when you Method signature does not match your POST data or when your Routing is not configured correctly.

404错误主要发生在方法签名与POST数据不匹配或路由配置不正确时。

Have a look at my answer here - Webservice return 404

看看我的答案 - Webservice返回404

I would change the Method signature to accept a class instead.

我会改变Method签名来接受一个类。

public class UserRights
{
    public int id {get;set;}
    public int RightId {get;set;}
    public bool Enable {get;set;}
}

Post Actions can not have most one argument in body. Create a class with the parameters you need. ASP NET will do the binding.

Post Actions在body中不能包含大多数参数。使用您需要的参数创建一个类。 ASP NET会做绑定。

public IHttpActionResult SetUserRights(Right right){ /* ... */ }

public class Right {
    public int id { get; set; }
    public int RightId { get; set; }
    public bool Enable { get; set; }
}

Try this.
