C#模拟httpwebrequest请求_向服务器模拟cookie发送

使用C#代码模拟web请求，是一种常用的方法，以前没专门整理过，这里暂时贴上自己整理的完整代码，以后再做梳理：

public class MyRequest
    {
        #region 辅助方法
        public static string HttpGet(string url)
        {
            var request = (HttpWebRequest)WebRequest.Create(url);

            var response = (HttpWebResponse)request.GetResponse();
            var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
            return responseString;
        }
        /// <summary>
        /// httpPost请求--参数为object
        /// </summary>
        /// <param name="url">地址</param>
        /// <param name="postObject">Post参数传输为对象</param>
        /// <returns></returns>
        public static string HttpPost(string url, object postObject, string at = "", string rt = "")
        {
            string result = string.Empty;

            try
            {
                var request = (HttpWebRequest)WebRequest.Create(url);
                var postData = JsonConvert.SerializeObject(postObject);

                var data = Encoding.UTF8.GetBytes(postData);  //uft-8支持中文
                request.Method = "POST";
                //request.ContentType = "application/x-www-form-urlencoded";
                request.ContentType = "application/json;charset=UTF-8";
                //request.ContentLength = data.Length;

                //这里使用了coolie容器，用来模拟向服务器发送cookie信息
                CookieContainer zl_Cookie = new CookieContainer();
                zl_Cookie.Add(new Cookie("at", at, "/", ".zhaopin.com"));
                zl_Cookie.Add(new Cookie("rt", rt, "/", ".zhaopin.com"));
                request.CookieContainer = zl_Cookie;

                using (var stream = request.GetRequestStream())
                {
                    stream.Write(data, , data.Length);
                }

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                result = new StreamReader(response.GetResponseStream()).ReadToEnd();
            }
            catch (Exception ex)
            {
                result = ex.Message;
            }
            //Console.WriteLine("发送消息结果：" + result);
            return result;
        }
        /// <summary>
        /// httpPost请求--参数为string
        /// </summary>
        /// <param name="url">地址</param>

        /// <returns></returns>
        public static string HttpPost(string url, string postString)
        {
            string result = string.Empty;

            try
            {
                var request = (HttpWebRequest)WebRequest.Create(url);

                var data = Encoding.UTF8.GetBytes(postString);  //uft-8支持中文
                request.Method = "POST";
                //request.ContentType = "application/x-www-form-urlencoded";
                request.ContentType = "application/json;charset=UTF-8";
                request.ContentLength = data.Length;

                using (var stream = request.GetRequestStream())
                {
                    stream.Write(data, , data.Length);
                }

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                result = new StreamReader(response.GetResponseStream()).ReadToEnd();
            }

            }

            return result;
        }
        #endregion
