Question

我使用的是.NET Web API，我希望将新创建的cookie与在Web API中生成的字符串一起发送。

C＃代码：

public Tuple<HttpResponseMessage, string> CookieMessage()
{
        string result = "Cookie Created Successfully !";

        CookieHeaderValue serverCookie = new CookieHeaderValue("", "");

        serverCookie = new CookieHeaderValue
                                ("IEM", "Success");
        serverCookie.Expires = DateTimeOffset.Now.AddMinutes(15);
        serverCookie.Domain = Request.RequestUri.Host;
        serverCookie.Path = "/";


    HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK);

    response.Headers.AddCookies(new CookieHeaderValue[] { serverCookie });

    return Tuple.Create(response, result);

}

我如何发送回复"Cookie Created Successfully !"以及Cookie serverCookie

请帮助我如何在客户的一个回复中发送这两个。我收到 500内部服务器错误

我在响应中看到了以下消息

您将返回不受支持的类型。我确信该框架永远无法序列化Tuple<HttpResponseMessage, string>。如果要修改响应标头，则只需返回HttpResponseMessage。

这应该按照您的预期运作：

public HttpResponseMessage CookieMessage()
{
    var response = Request.CreateResponse<string>(
        HttpStatusCode.OK,
        "Cookie Created Successfully !"
    );

    var cookie = new CookieHeaderValue("IEM", "Success");
    cookie.Expires = DateTimeOffset.Now.AddMinutes(15);
    cookie.Domain = Request.RequestUri.Host;
    cookie.Path = "/";

    response.Headers.AddCookies(new CookieHeaderValue[] { cookie });

    return response;
}

返回Cookie以及.NET Web API中的对象
