简介: 本篇博文是针对本人在开发企业微信消息交互的一些经验分享，介绍一下自己开发过程中遇到的问题和解决方法,如果问题或异议，欢迎讨论，技术大佬请忽略
用户在企业微信中有2种用户操作可以发送给我们服务器1、点菜微信企业应用的菜单
2、给企业微信发送文字或者图片等信息
企业微信要接受到用户行为（比如对企业号发消息或者点击企业号中的菜单）需要再对应的企业微信应用中配置接受消息模块：1、首先进入企业微信配置接受消息
2、配置对应的URL，Token以及EncodingAESKey：
在后台编写程序解析用户行为操作并回复用户不同消息1、接受微信发过来的加密报文解析用户行为操作
public void ProcessRequest(HttpContext context) { var Request = context.Request; var Response = context.Response; context.Response.ContentType = "text/plain"; //context.Response.ContentType = "text/xml"; //公众平台上开发者设置的token, corpID, EncodingAESKey string sCorpID = System.Configuration.ConfigurationManager.AppSettings["sCorpID"]; string sToken = ""; string sEncodingAESKey = ""; WXBizMsgCrypt wxcpt = new WXBizMsgCrypt(sToken, sEncodingAESKey, sCorpID); string sVerifyMsgSig = Request.QueryString["msg_signature"]; string sVerifyTimeStamp = Request.QueryString["timestamp"]; string sVerifyNonce = Request.QueryString["nonce"]; string sVerifyEchoStr = Request.QueryString["echostr"] ?? ""; int ret = 0; string sEchoStr = ""; //获取表单提交内容 string postStr = string.Empty; using (System.IO.StreamReader sr = new System.IO.StreamReader(Request.InputStream)) { postStr = sr.ReadToEnd(); } if (!string.IsNullOrEmpty(postStr)) { var xmldoc = new XmlDocument(); xmldoc.LoadXml(postStr); XmlNode root = xmldoc.FirstChild; string sPostData = root["Encrypt"].InnerText; ret = wxcpt.DecryptMsg(sVerifyMsgSig, sVerifyTimeStamp, sVerifyNonce, postStr, ref sEchoStr); if (ret != 0) { SH.Utilities.Base.Log.LogHelper.Info("WeChat", "ERR: VerifyURL fail, ret: " + ret); return; } //封装请求类 XmlDocument requestDocXml = new XmlDocument(); requestDocXml.LoadXml(sEchoStr); XmlElement rootElement = requestDocXml.DocumentElement; WxXmlModel WxXmlModel = new WxXmlModel(); WxXmlModel.ToUserName = rootElement.SelectSingleNode("ToUserName").InnerText; WxXmlModel.FromUserName = rootElement.SelectSingleNode("FromUserName").InnerText; WxXmlModel.CreateTime = rootElement.SelectSingleNode("CreateTime").InnerText; WxXmlModel.MsgType = rootElement.SelectSingleNode("MsgType").InnerText; WxXmlModel.AgentID = rootElement.SelectSingleNode("AgentID").InnerText; WxXmlModel.CompanyId = companyid; switch (WxXmlModel.MsgType) { case "text"://文本 WxXmlModel.Content = rootElement.SelectSingleNode("Content").InnerText; break; case "image"://图片 WxXmlModel.PicUrl = rootElement.SelectSingleNode("PicUrl").InnerText; break; case "event"://事件 WxXmlModel.Event = rootElement.SelectSingleNode("Event").InnerText; if (WxXmlModel.Event == "click")//菜单点击 { WxXmlModel.EventKey = rootElement.SelectSingleNode("EventKey").InnerText; SH.WebApp.WeChatHelper.Report.sendMsg(WxXmlModel); } break; default: break; } string sReplyMsg = ResponseXML(WxXmlModel);//回复消息 ret = wxcpt.EncryptMsg(sReplyMsg, sVerifyTimeStamp, sVerifyNonce, ref sEchoStr); if (ret != 0) { return; } Response.Write(sEchoStr); Response.End(); return; } else { string sEncryptMsg = ""; ret = wxcpt.VerifyURL(sVerifyMsgSig, sVerifyTimeStamp, sVerifyNonce, sVerifyEchoStr, ref sEncryptMsg); if (ret != 0) { SH.Utilities.Base.Log.LogHelper.Info("", "ERR: VerifyURL fail, ret: " + ret); Response.Write(""); Response.End(); return; } Response.Write(sEncryptMsg); Response.End(); return; } }2、根据不同用户行为操作做不同的消息类型回复
private string ResponseXML(WxXmlModel WxXmlModel){string XML = "";switch (WxXmlModel.MsgType){case "text"://文本回复//批号查询if (SH.WebApp.Extension.Utilities.IsBatchNumber(WxXmlModel)){WxXmlModel.EventKey = "BatchNumber_Search";XML = SH.WebApp.WeChatHelper.Report.sendMsg(WxXmlModel);}//流转卡查询else if (SH.WebApp.Extension.Utilities.IsTransferCard(WxXmlModel)){WxXmlModel.EventKey = "TransferCard_Search";XML = SH.WebApp.WeChatHelper.Report.sendMsg(WxXmlModel);}//默认自动回复else{XML = ResponseMessage.GetText(WxXmlModel.FromUserName, WxXmlModel.ToUserName, WxXmlModel.Content);}break;case "event":switch (WxXmlModel.Event){//点击菜单case "click":if (string.IsNullOrEmpty(WxXmlModel.EventKey)){XML = SH.WebApp.WeChatHelper.Report.sendMsg(WxXmlModel);}break;case "SCAN":XML = ResponseMessage.ScanQrcode(WxXmlModel.FromUserName, WxXmlModel.ToUserName, WxXmlModel.EventKey);//扫描带参数二维码已关注 直接推送事件break;}break;default://默认回复break;}return XML;}3、图文消息发送，
