微信开发回复用户消息的代码实例分享

这里做个知识总结分享下经验，望一起学习。。。。。

感觉后面写个系列的最好了 。。。。

企业需求：

给指定企业用户http://www.php.cn/php/php-s发送消息：如考勤信息、 企业通知、个人信息推送等等,

/// </summary>        /// <param name="UserID">要发送的人ID</param>        /// <param name="StrMessg">消息</param>        private void SendMessage(string UserID, string StrMessg)        {            Como.LogUtil.WriteLog("回复用户" + UserID + "消息");            string Access_Token = Como.GetAccessToken.GetAccess_token();            if (Access_Token == "")                Como.LogUtil.WriteException("SendMessage 未能成功加载Access_Token");            string Text = @"{   ""touser"":";            Text += '"' + UserID + '"';            Text += "," + '"' + @"msgtype"": ""text"",            ""agentid"": ""5"",             ""text"": {           ""content"":";            Text += '"' + StrMessg + '"';            Text += @"},     ""safe"": ""0""}";            ;            string url = String.Format("https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={0}", Access_Token);            string strResult = Como.Tools.GetPage(url, Text);            JArray ja = (JArray)JsonConvert.DeserializeObject("[" + strResult + "]");            string Error = "";            try            {                if (strResult.Contains("errcode"))                {                    Error = ja[0]["errcode"].ToString();                }            }            catch (Exception ex)            {                Como.LogUtil.WriteException("获取strResult,未获取到错误信息" + ex.Message.ToString());            }            string errcode = ja[0]["errcode"].ToString();            string errmsg = ja[0]["errmsg"].ToString();            if (errcode == "0" && errmsg == "ok")            {                Como.LogUtil.WriteLog("回复成功！");            }            else            {                Como.LogUtil.WriteLog("回复失败！");                Como.LogUtil.WriteException("回复失败：SendMessage：" + strResult);             }        }

/// <summary>        /// 根据请求地址 和数据返回请求结果        /// </summary>        /// <param name="posturl"></param>        /// <param name="postData"></param>        /// <returns></returns>        public static string GetPage(string posturl, string postData)        {            Stream outstream = null;            Stream instream = null;            StreamReader sr = null;            HttpWebResponse response = null;            HttpWebRequest request = null;            Encoding encoding = Encoding.UTF8;            byte[] data = encoding.GetBytes(postData);            // 准备请求...            try            {                // 设置参数                request = WebRequest.Create(posturl) as HttpWebRequest;                CookieContainer cookieContainer = new CookieContainer();                request.CookieContainer = cookieContainer;                request.AllowAutoRedirect = true;                request.Method = "POST";                request.ContentType = "application/x-www-form-urlencoded";                request.ContentLength = data.Length;                outstream = request.GetRequestStream();                outstream.Write(data, 0, data.Length);                outstream.Close();                //发送请求并获取相应回应数据                response = request.GetResponse() as HttpWebResponse;                //直到request.GetResponse()程序才开始向目标网页发送Post请求                instream = response.GetResponseStream();                sr = new StreamReader(instream, encoding);                //返回结果网页（html）代码                string content = sr.ReadToEnd();                string err = string.Empty;                return content;            }            catch (Exception ex)            {                string err = ex.Message;                Como.LogUtil.WriteException("Tools GetPage 异常为："+err.ToString());                return string.Empty;            }        }

参数引用详解：

1.Como.GetAccessToken.GetAccess_token() //获取 Access_token

2.GetPage //返回页面请求信息 结果

以上为基础发送关键代码：
