mvc cookie 基于C#后台调用跨域MVC服务及带Cookie验证的实现

　　　　CookieContainer cookieContainer = new CookieContainer();

　　　　 [HttpPost]
        public string CommonPost(string url)
        {
            log.Info(CookieHelper.GetCookie("ITDC_UserName") + "进入方法CommonPost Url=" + url);
            Uri address = new Uri(System.Configuration.ConfigurationManager.AppSettings["RESTfulAPI"].ToString() + url);
            HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
　　　　　　　//远程服务,需要加入cookie验证
            cookieContainer.Add(address, GetCookie("ITDC_UserName"));
            cookieContainer.Add(address, GetCookie("ITDC_UserRole"));
            request.CookieContainer = cookieContainer;
            StringBuilder data = new StringBuilder();
            for (int i = 0; i < Request.QueryString.Count; i++)
            {
                if (Request.QueryString.Keys[i].ToString() == "url") continue;
                data.Append("&" + Request.QueryString.Keys[i].ToString() + "=" + Request.QueryString[i].ToString());
            }
            // Create a byte array of the data we want to send
            byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString().TrimStart('&'));
            // Set the content length in the request headers
            request.ContentLength = byteData.Length;
            // Write data 
            using (Stream postStream = request.GetRequestStream())
            {
                postStream.Write(byteData, 0, byteData.Length);
            } 
            string result = "";
            using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
            {
                StreamReader reader = new StreamReader(response.GetResponseStream());
                result = reader.ReadToEnd();
            }
            log.Info(CookieHelper.GetCookie("ITDC_UserName") + " 执行完成 CommonPost Url=" + url);
            return (result);
