一般情况下传输和回传HTTP协议就搞定了，但这次不同，有身份验证，网上的资料相对较少，怎么办呢？.NET没有不代表JAVA没有，网上搜JAVA身份验证HTTP协议，

果然是有的，跟着代码改成相应的.NET代码，就是下面这玩意：

/// 
        /// 服务器网络凭证        /// 
        /// 
             public NetworkCredential MyCredc(string loginUser, string loginPSW)        {            string loginHost = "";//主机名，可以是IP地址，也可以服务器名称            NetworkCredential myCred = new NetworkCredential(loginUser, loginPSW);            return myCred;        }

try     {                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url + "?formInfo=" + JsonConvert.SerializeObject(obj));                request.Credentials = MyCredc(adm, pas);  //凭证就是这玩意                request.Headers.Add("CSRF_NONCE", acquireWindchillToken(tokenUrl));                request.Method = "POST";                using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)                {                    StreamReader reader = new StreamReader(response.GetResponseStream());                }            }            catch (Exception ex)            {                throw new Exception(ex.Message);            } }
