使用Post方法将数据从JavaScript发布到ApiController

我通过javascript代码调用webservice，如下所示：

function callActionAjax(action, data) { //action is "sendnotification"
    var deferred = jQuery.Deferred();
    getWebServiceUrl().done(function (webServiceUrl) { //returns https://server/api
        var s = {
            crossDomain: true,
            xhrFields: { withCredentials: true },
            url: webServiceUrl + "/" + action,
            data: "foobar", //also tried: JSON.stringify(data)
            type: "POST"
            //tried contentType: "application/json"
        };
        jQuery.ajax(s).done(function () {
            deferred.resolve();
        }).fail(function () {
            deferred.reject();
        });
    });
    return deferred.promise();
}

public class SendNotificationController : ApiController
{
    public void PostSendNotification(dynamic data)
    {
        Console.Write("foo");
    }

    public string GetSendNotification()
    {
        return "Foo Bar.";
    }
}

我还有MVC服务，它接收请求。我的控制器如下所示：

function callActionAjax(action, data) { //action is "sendnotification"
    var deferred = jQuery.Deferred();
    getWebServiceUrl().done(function (webServiceUrl) { //returns https://server/api
        var s = {
            crossDomain: true,
            xhrFields: { withCredentials: true },
            url: webServiceUrl + "/" + action,
            data: "foobar", //also tried: JSON.stringify(data)
            type: "POST"
            //tried contentType: "application/json"
        };
        jQuery.ajax(s).done(function () {
            deferred.resolve();
        }).fail(function () {
            deferred.reject();
        });
    });
    return deferred.promise();
}

public class SendNotificationController : ApiController
{
    public void PostSendNotification(dynamic data)
    {
        Console.Write("foo");
    }

    public string GetSendNotification()
    {
        return "Foo Bar.";
    }
}

我在PostSendNotification中有一个断点。我可以看到，该方法接收到请求，但是

数据

只是一个空对象。当我尝试在JS端添加

contentType

时，断点不会被命中

如何调整我的代码？最后，我希望在控制器中检索我的

数据

，并能够对其进行处理

改变你的想法

    type: "POST"

到

尝试将参数类型更改为string，而不是使用dynamic，并在java脚本中将数据“foobar”修改为数据：{data:“foobar”}，
