AJAX删除操作转到错误的方法

我正试图通过AJAX调用从数据库中删除记录,如下所示:

$.ajax({
    type: 'POST',
    url: '/api/Person/DeletePerson',
    data: { personId: personId },
    contentType: 'application/json',
    success: function (data) {
        if (data != null) {

        }
    },
    error: function (err, data) {
        alert("Error " + err.responseText);
    }
});

这是它应该输入的方法:

public void DeletePerson(int personId)
{
var t = 0; // i'm breaking the debugger right here, never gets hit.
}

但相反,它一直在输入这个方法:

public HttpResponseMessage PostPerson(dynamic person)
{
    HttpResponseMessage response;

    if (User.Identity.GetUserId() == null)
    {
        response = Request.CreateResponse(HttpStatusCode.Forbidden, "Please log in."); 
    }

    return response;
}

两种方法都位于WebApi Controller

AJAX Type: delete不受支持。如果我使用它,我会收到此消息:

The requested resource does not support http method 'delete'

我该如何完成这项工作?

修改

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

调用Delete方法(因为这是一个休息实现),使用DELETE动词调用/ api / Person / URL。

$.ajax({
    type: 'DELETE',
    url: '/api/Person',
    data: { personId: personId },
    contentType: 'application/json',
    success: function (data) {
        if (data != null) {

        }
    },
    error: function (err, data) {
        alert("Error " + err.responseText);
    }
});

否则,您需要更新操作以接受带有

的删除动词
[HttpDelete]
public void DeletePerson(int personId)
{
var t = 0; // i'm breaking the debugger right here, never gets hit.
}

如果要让控制器从JSON有效负载而不是请求URL中查找id,请重写如下。

public void DeletePerson([FromBody]int personId)
{
    var t = 0; // i'm breaking the debugger right here, never gets hit.
}
