微信开发回复用户消息的代码实例分享

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：
