JQuery ajax调用在200上执行错误

我的c#/ WebApi服务器代码如下所示:

[HttpPost]
public HttpResponseMessage Logout()
{
    // do some stuff here ... 
    return Request.CreateResponse(HttpStatusCode.OK);
}

在客户端,我使用jquery 2.0.3进行ajax调用

ADDED:Jquery代码(typescript)......

    var ajaxSettings: JQueryAjaxSettings = {};
    ajaxSettings.type = 'POST';
    ajaxSettings.data = null;
    ajaxSettings.contentType = "application/json; charset=utf-8";
    ajaxSettings.dataType = "json";
    ajaxSettings.processData = false;

    ajaxSettings.success = (data: any, textStatus: string, jqXHR: JQueryXHR) => {
        console.log("Success: textStatus:" + textStatus + ", status= " + jqXHR.status);
    };
    ajaxSettings.error = (jqXHR: JQueryXHR, textStatus: string, errorThrow: string) => {
        console.log("Error: textStatus:" + textStatus + ", errorThrow = " + errorThrow);
    };

    $.ajax("http://apidev.someurl.com/v1/users/logout", ajaxSettings);

增加2:上述代码产生的请求标头:

POST http://apidev.someurl.com/v1/users/logout HTTP/1.1
Host: apidev.someurl.com
Connection: keep-alive
Content-Length: 0
Cache-Control: no-cache
Pragma: no-cache
Origin: http://apidev.someurl.com
Authorization: SimpleToken 74D06A21-540A-4F31-A9D4-8F2387313998
X-Requested-With: XMLHttpRequest
Content-Type: application/json; charset=utf-8
Accept: application/json, text/javascript, */*; q=0.01
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36

Accept-Encoding: gzip,deflate,sdch

响应是200,但是ajax调用的错误处理程序被触发而不是成功处理程序.原因:parseerror,意外结束输入.

一种解决方案是将服务器端代码更改为:

return Request.CreateResponse(HttpStatusCode.OK, "Logout ok");

我知道空响应是无效的JSON,但响应消息是故意为空的.200说了这一切.响应标头如下所示:

HTTP/1.1 200 OK
Cache-Control: no-cache
Pragma: no-cache
Expires: -1
Server: Microsoft-IIS/7.5
Access-Control-Allow-Origin: http://apidev.someurl.com

这是jquery中的错误吗？或者Request.CreateResponse(OK)是否应该以这种方式使用？我应该在客户端解决这个问题吗？AFAIK服务器在这里做错了......有什么想法吗？

编辑:感谢凯文,尼克和约翰的反馈,这个问题已经变得清晰了.我选择的解决方案是返回NoContent

return Request.CreateResponse(HttpStatusCode.NoContent);

在这种情况下,Serverside似乎是正确的代码.客户端这是由JQuery完美处理的(调用成功处理程序).Thanx所有清理这个!

(我不知道是谁给出了答案的答案......因为尼克和凯文在评论中给出了宝贵的反馈,约翰的反馈也增加了更好的理解)......如果没有给出其他建议......我会以后标记唯一的'答案'为答案)

谢谢大家!
