微信开发 回复用户消息 .net C#

前段时间开发了公司的微信

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：
