PostMan发送body的内容是XML和和后台接收

         [HttpPost]
        public async Task<ActionResult> SOConfirm(XmlDocument doc)//string appid, string token,
        {
           
            ActionResult result = null;try
            {               
                //解析下XML-->json
                //下面标红的进行了二次的转换，并不是直接解析xml的，因为，直接用的话，
                //转出来的json会有就给我解出来"#whitespace"，"#text"等这玩意
                //二次转后就不会有那些个异样的字符串

                XmlDocument doctext = new XmlDocument();
                doctext.LoadXml(doc.InnerXml);
                string json = Newtonsoft.Json.JsonConvert.SerializeXmlNode(doctext);
                var j = JObject.Parse(json);  if (string.IsNullOrEmpty(j["request"]["orderDetails"]["detail"].ToString()))
                {
                    throw new ECOrderException { ErrorCode = "SOConfirmVwms_02", TransMessage = "订单明细不能为空" };
                }

                //存到sql的必要的数据
                string deliveryOrderCode = j["request"]["deliveryOrder"]["deliveryOrderCode"].ToString();
                string warehouseCode = j["request"]["deliveryOrder"]["warehouseCode"].ToString();

  services.AddMvc()
              .AddXmlSerializerFormatters();
一定要注册服务，不注册服务上面的参数，XmlDocument 根本接收不到值
