这是客户端调用Post的方法

public static string HttpPost1(string url,string JsonData)
        {
            Encoding encoding = Encoding.UTF8;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Method = "Post";            
            request.Accept = "text/html,application/xhtml+xml,*/*";
            request.ContentType = "application/json";

            var byteData = Encoding.UTF8.GetBytes(JsonData);
            var length = byteData.Length;
            request.ContentLength = length;
            var writer = request.GetRequestStream();
            writer.Write(byteData, 0, length);
            writer.Close();

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
            {
                return reader.ReadToEnd();
            }
        }

string url_p = "http://localhost:61657/api/test";
this.text_Res.Text = HttpPost2(url_p, json_g);

下面是服务端对Post的定义

public Getres Post(string json_get)
{
xxxxxxxx
}

为什么老是会报错405啊.....不理解哪个环节出了问题
