C#Json请求获胜'；行不通

因此，基本上我正在尝试向发送一个json请求，json将结束{“召唤名称”：“DeCodux”}，但我的问题是，这段代码似乎没有向他们的Web服务器上的mmr.json中发送任何内容

var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://op.gg/mmr/ajax/mmr.json");
                httpWebRequest.ContentType = "text/json";
                httpWebRequest.Method = "POST";

                using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
                {
                    string json = new JavaScriptSerializer().Serialize(new
                    {
                        summonerName = "DeCodux"
                    });

                    streamWriter.Write(json);
                    streamWriter.Flush();
                    streamWriter.Close();

                    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
                    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
                    {
                        var result = streamReader.ReadToEnd();
                        DataBox.Text = result;
                    }
                }

这段代码也不会

var request = (HttpWebRequest)WebRequest.Create("http://op.gg/mmr/ajax/mmr.json/");
                request.Method = "POST";
                request.Host = "op.gg";
                request.Accept = "application/json, text/javascript, */*";
                request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
                request.Referer = "http://op.gg/mmr/region=EUW";
                //request.ContentLength = 27;
                //request.Connection = "keep-alive";
                using (var writer = new StreamWriter(request.GetRequestStream()))
                {
                    string writeit = "{\"summonerName\":\"DeCodux\"}";

                // string writethis = "{\"region\"=\"EUW\"," + "\"userName\"=\"DeCodux\"}";
                    writer.Write(writeit);


                }

                var response = request.GetResponse();
                var stream = response.GetResponseStream();
                var json = "";

                if (stream == null) return;
                using (var reader = new StreamReader(stream))
                 {
                    while (!reader.EndOfStream)
                    {
                        json += reader.ReadLine();
                    }
                }
                #endregion oldtest
                /* var serializer = new JavaScriptSerializer();
                var x = (Dictionary<string, object>)serializer.DeserializeObject(json);
                MyData data = serializer.Deserialize<MyData>(x.ToString());*/
               /* var jss = new JavaScriptSerializer();
                var data = jss.Deserialize<Dictionary<string, string>>(json);
                */
                DataBox.Text = json;

被解析和翻译的是

{
"error": true,
"errormsg": "Please enter the name of the Summoner." }

因此，由于它将该错误作为响应提供给我，因此我的json请求似乎没有发送到他们的服务器。如果请求将被发送，但它将是不正确的，它将给我其他错误，如“此召唤者不--”等等。我还用firebug“net”模式浏览了所有的post请求头等

所以我的问题是，这里出了什么问题？为什么它不发送POST请求？

你确定你有

传唤人姓名

吗？是的，我确定。使用firebug检查了数十次，您可以亲自尝试，方法是：进入op.gg/mrr，输入您想要的任何名称，然后按“Get mmr”，然后检查firebug的net选项卡。

{
"error": true,
"errormsg": "Please enter the name of the Summoner." }
