返回Cookie以及.NET Web API中的Object-Java 学习之路

我正在使用.NET Web API，我希望发送新创建的cookie以及在Web API中生成的字符串 .

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);

}

我如何发送响应 "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 Internal Server Error

我在Response中看到了以下消息

{“Message”：“发生错误 . ”，“ExceptionMessage”：“'ObjectContent`1'类型无法序列化内容类型'application / json; charset = utf-8'的响应正文 . ”，“ ExceptionType“：”System.InvalidOperationException“，”StackTrace“：null，”InnerException“：{”消息“：”发生了错误 . “，”ExceptionMessage“：”从'System.Version'上的'SeparatorsArray'获取值时出错“ . “，”ExceptionType“：”Newtonsoft.Json.JsonSerializationException“，”StackTrace“：”at Newtonsoft.Json.Serialization.DynamicValueProvider.GetValue（Object target）\ r \ n在Newtonsoft.Json.Serialization.JsonSerializerInternalWriter.CalculatePropertyValues（JsonWriter）在Newtonsoft.Json.Serialization.JsonSerializerInternalWriter .SerializeObject（JsonWriter writer，Object value，JsonObjectContract contract，JsonProperty member，JsonContainerContract collectionContract）中的writer，Object value，JsonContainerContract contract，JsonProperty成员，JsonProperty属性，JsonContract＆memberContract，Object＆memberValue）\ r \ n ，J在Newtonsoft.Json.Serialization.JsonSerializerInternalWriter .SerializeObject （JsonWriter编写器，Object值，JsonObjectContract Contract ，JsonProperty成员，JsonContainerContract collectionContract，JsonProperty containerProperty）\ r \ n在Newtonsoft.Json.Serialization.JsonSerializerInternalWriter .SerializeValue（JsonWriter writer，Object value，JsonContract valueContract，JsonProperty成员，JsonContainerContract containerContract，JsonProperty） containerProperty）\ r \ n在Newtonoft.Json.Serialization.JsonSerializerInternalWriter .SerializeObject（JsonWriter writer，Object value，JsonObjectContract contract，JsonProperty member，JsonContainerContract collectionContract，JsonProperty containerProperty）\ r \ n at Newtonso ft.Json.Serialization.JsonSerializerInternalWriter .SerializeValue（JsonWriter writer，Object value，JsonContract valueContract，JsonProperty成员，JsonContainerContract containerContract，JsonProperty containerProperty）\ r \ n在Newtonsoft.Json.Serialization.JsonSerializerInternalWriter .Serialize（JsonWriter jsonWriter，Object value）\ r \ n at Newoftoft.Json.JsonSerializer.SerializeInternal（JsonWriter jsonWriter，Object value）\ r \ n在Newtonsoft.Json.JsonSerializer.Serialize（JsonWriter jsonWriter，Object value）\ r \ n在System.Net.Http.Formatting .

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> . 如果要修改响应头，则只需返回 HttpResponseMessage .

这应该按预期工作：

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;
}
