Question

澄清：POST请求位于同一项目中的不同网站或不同控制器之间。

我想将Json数据发布到另一个操作方法。我使用Newtonsoft进行json序列化，事实是在JsonMethod中，字段Name带有null。我错过了什么吗？

我的模特：

class Person
{
 [JsonProperty("name")]
 public string Name{get;set;}
}

发布json的动作方法：

public ActionResult Method1()
{
  Person p = new Person(){Name = "Test"}
  string urlToRedirect = "..urlRoute../JsonMethod";
  var res = SendRequest(urlToRedirect, p);

  //...do anything with res
}

接收模型的方法

[HttpPost]
public ActionResult JsonMethod(Person p)
{
    if(p.Name == "Test")
      return Json("ok");
    else return Json("bad");
}

发送请求的方法

    public async bool SendRequestAsync(string requestUrl, object data) 
    {
        string json = JsonConvert.SerializeObject(obj, Formatting.Indented,
                                 new JsonSerializerSettings
                                 {
                                     ReferenceLoopHandling = ReferenceLoopHandling.Ignore
                                 });

        try
        {
            HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;

            if (request != null)
            {
                request.Accept = "application/json";
                request.ContentType = "application/json";
                request.Method = "POST";

                using (var stream = new StreamWriter(await request.GetRequestStreamAsync()))
                {
                    stream.Write(json);
                }

                using (HttpWebResponse response = await request.GetResponseAsync() as HttpWebResponse)
                {
                    if (response != null && response.StatusCode != HttpStatusCode.OK)
                        throw new Exception(String.Format(
                            "Server error (HTTP {0}: {1}).",
                            response.StatusCode,
                            response.StatusDescription));

                    if (response != null)
                    {
                        Stream responseStream = response.GetResponseStream();
                        //return true or false depending on the ok
                        return GetResponseModel(responseStream);
                    }
                }
            }
        }
        catch (WebException ex)
        {
            var response = ex.Response;
            Stream respStream = response.GetResponseStream();
            //return true or false depending on the ok
            return GetResponseModel(respStream);

        }
        catch (Exception e)
        {
            return false;
        }

        return false;
    }

我的错误是人的“名字”属性属性，它必须是大写字母“姓名”。这就是为什么它是空的。

[JsonProperty（ “名称”）]
