ISV 创建套件，回调URL 解析eventType 老是返回 checkcreatesuiteurl

套件要创建成功后才能获取ticket,这个回调的处理，可以参考下文档

楼主 这个问题怎么解决的呢  ，我也遇到了

              #region 获取套件配置参数
                string mToken = ConfigurationManager.AppSettings["Token"];
                string mSuiteKey = "";
                string mEncodingAesKey = ConfigurationManager.AppSettings["EncodingAESKey"];
                mSuiteKey = "suite4xxxxxxxxxxxxxxx";
                #endregion

                #region 获取回调URL里面的参数
                //url中的签名
                string msgSignature = context.Request["signature"];
                //url中的时间戳
                string timeStamp = context.Request["timestamp"];
                //url中的随机字符串
                string nonce = context.Request["nonce"];
                //post数据包数据中的加密数据
                string encryptStr = GetPostParam(context);
                #endregion

                Helper.WriteLog("post方法");

              
                string sEchoStr = "";

                #region 验证回调的url
                SuiteAuth suiteAuth = new SuiteAuth();

                Helper.WriteLog("mToken: " + mToken);
                Helper.WriteLog("mEncodingAesKey: " + mEncodingAesKey);
                Helper.WriteLog("msgSignature: " + msgSignature);
                Helper.WriteLog("timeStamp: " + timeStamp);
                Helper.WriteLog("nonce: " + nonce);
                Helper.WriteLog("encryptStr: " + encryptStr);


                var ret = suiteAuth.VerifyURL(mToken, mEncodingAesKey, msgSignature, timeStamp, nonce, encryptStr,
                    ref mSuiteKey);

                if (ret != 0)
                {
                    Helper.WriteLog("ERR: VerifyURL fail, ret: " + ret);
                    return;
                }
                #endregion

                #region
                //构造DingTalkCrypt

                DingTalkCrypt dingTalk = new DingTalkCrypt(mToken, mEncodingAesKey, mSuiteKey);

                string plainText = "";
                dingTalk.DecryptMsg(msgSignature, timeStamp, nonce, encryptStr, ref plainText);

                Hashtable tb = (Hashtable)JsonConvert.DeserializeObject(plainText, typeof(Hashtable));
                string eventType = tb["EventType"].ToString();
                string res = "success";
                Helper.WriteLog("plainText:" + plainText);
                Helper.WriteLog("eventType:" + eventType);
                switch (eventType)-----------------------------------------------------------------------就是在这里，老是获取的是 check_create_suite_url
                {
                  
                    case "suite_ticket"://定时推送Ticket
                        ConfigurationManager.AppSettings["SuiteTicket"] = tb["SuiteTicket"].ToString();
                        mSuiteKey = tb["SuiteKey"].ToString();
                        suiteAuth.SaveSuiteTicket(tb);
                        break;
                    case "tmp_auth_code"://钉钉推送过来的临时授权码
                        ConfigurationManager.AppSettings["TmpAuthCode"] = tb["AuthCode"].ToString();
                        suiteAuth.SaveTmpAuthCode(tb);
                        break;
                    case "change_auth":// do something;
                        break;
                    case "check_update_suite_url":
                        res = tb["Random"].ToString();
                        mSuiteKey = tb["TestSuiteKey"].ToString();
                        break;
                }

                timeStamp = Helper.GetTimeStamp().ToString();
                string encrypt = "";
                string signature = "";
                dingTalk = new DingTalkCrypt(mToken, mEncodingAesKey, mSuiteKey);
                dingTalk.EncryptMsg(res, timeStamp, nonce, ref encrypt, ref signature);
                Hashtable jsonMap = new Hashtable
                {
                    {"msg_signature", signature},
                    {"encrypt", encrypt},
                    {"timeStamp", timeStamp},
                    {"nonce", nonce}
                };
                string result = JsonConvert.SerializeObject(jsonMap);
                Helper.WriteLog("result: " + result);

                context.Response.Write(result);
