How to handle-if config server sends EventObjectsSent response to RequestReadObj

(1/2) > >>

Hi Genesys Wizards,

Request your help in understanding how to handle the below Scenario , I am trying to do some sequence of events as below.
Connect to Config server
Get the DBID of a user from CFGperson then get corresponding tenant_dbid / login code of that person ... I have pasted the code that I am using for the same.

Please bear any fatal flaws in method invocation procedures ,  I am just beginning to learn to work with Genesys SDKs , please advice.


[code]

/// Step 1 Opening a connection ////

                confServerProtocol.Open(); // opening a connection


///Step 2 Authenticating a Username and password of a User whose details are available in CME ... ///

            RequestAuthenticate RequestAuthenticateObj = RequestAuthenticate.Create(AgentName, Agentpassw);
            confServerProtocol.Send(RequestAuthenticateObj);

/// Step 3 Once authenticated I am trying to get the DBID of that User from Cfgperson ... the user who is authenticated above ///
/// and  once done I am trying to further fetch his Login code from CfgAgentLogin ///

KeyValueCollection filterKey = new KeyValueCollection();
            filterKey.Add("user_name", username); // passing the username authenticated via Request Authenticate

                RequestReadObjects requestFilterQuery = RequestReadObjects.Create((int)CfgObjectType.CFGPerson, filterKey);
                confServerProtocol.Send(requestFilterQuery);

            IMessage respondingEvent = confServerProtocol.Receive();
            EventObjectsRead objectsRead = (EventObjectsRead)respondingEvent;
           
                StringBuilder xmlAsText = new StringBuilder();
                XmlWriterSettings xmlSettings = new XmlWriterSettings();
                xmlSettings.Indent = true;

                using (XmlWriter xmlWriter =
                    XmlWriter.Create(xmlAsText, xmlSettings))
                {
                    XDocument resultDocument = objectsRead.ConfObject;

                var DBIDValue = (from d in resultDocument.Descendants()
                                    where d.Name.LocalName == "DBID"
                                    select d.Attribute("value").Value).First();

                      DBID = Convert.ToInt32(lDBIDValue);

            }
/// Step 4  pass a filter query again with the DBID obtained from previous step.. to get his tenant id / logithis time I am getting below exception
        KeyValueCollection getlocid = new KeyValueCollection();
            getlocid.Add("dbid",DBID);

            RequestReadObjects requestFilterQuerylogincode = RequestReadObjects.Create((int)CfgObjectType.CFGAgentLogin, getlocid);
          confServerProtocol.Send(requestFilterQuerylogincode); /////// as seen the filter value sent is...  Filter = {KVList:'dbid' [int] = 119}

            IMessage message = confServerProtocol.Receive();

            EventObjectsRead objectsRead2 =(EventObjectsRead)message; //////////////////////////- Exception Here...
[/code]

Exception :
{"Unable to cast object of type 'Genesyslab.Platform.Configuration.Protocols.ConfServer.Events.EventObjectsSentData' to type 'Genesyslab.Platform.Configuration.Protocols.ConfServer.Events.EventObjectsRead'."}

Have a read of the SDK Documentation around Event Handling.  The short version is Configuration Server will send back many messages including EventObjectsSent and one or more EventObjectsRead for your request , and you're 'Receive' needs to work with all of those.  At the moment it looks like you're assuming it'll give you back an EventObjectsRead but you're actually getting the EventObjectsSent - causing the cast error.

I don't currently have Visual Studio installed, so I didn't test the code below, but I feel that would be way easier if you used ConfService. You would get rid of all the XmlDocument manipulation hell. For example:


[code]

/// Step 1 Opening a connection ////

// HSUJDIK: create the ConfService before opening the ConfServerProtocol:
EventBrokerService brokerService = BrokerServiceFactory.CreateEventBroker(protocol);
ConfService service = ConfServiceFactory.CreateConfService(confServerProtocol, brokerService);

                confServerProtocol.Open(); // opening a connection


///Step 2 Authenticating a Username and password of a User whose details are available in CME ... ///

            RequestAuthenticate RequestAuthenticateObj = RequestAuthenticate.Create(AgentName, Agentpassw);
            // HSUJDIK: use the method .Request instead of .Send so you will get the message back
            // without need to use the method .Receive()
            (Message) authResponse = confServerProtocol.Request(RequestAuthenticateObj);
            // HSUJDIK: check if EventAuthenticated or EventError was returned.
           

/// Step 3 Once authenticated I am trying to get the DBID of that User from Cfgperson ... the user who is authenticated above ///
/// and  once done I am trying to further fetch his Login code from CfgAgentLogin ///

// HSUJDIK:
CfgPersonQuery query = new CfgPersonQuery(confservice);
query.UserName("user_name");

CfgPerson person = null;

try {
person = query.ExecuteSingleResult();
} catch (Exception e) {
// ERROR TRYING TO GET THE USER PROPERTIES. Proceed as you wish
}

List<CfgAgentLogin> agentLogins = person.AgentInfo.AgentLogins;

foreach (CfgAgentLogin agentLogin in agentLogins) {

// HSUJDIK: Do whatever you need with each CfgAgentLogin

}


/// Step 4  pass a filter query again with the DBID obtained from previous step.. to get his tenant id / logithis time I am getting below exception

// HSUJDIK:
int dbid = person.Tenant.DBID;

[/code]

Hi hsujdik,

Thanks for your time for such a useful piece of code snippet.

I set out to try it as adviced , but in my previous connection opening I tried adding brokerservice below

[code]           
///////// Arul's code trial //////////////////

ConfServerProtocol confServerProtocol = new ConfServerProtocol(new Endpoint(Host, port));

            confServerProtocol.ClientApplicationType = (int)PsdkCustomization.CustomOption("Samples.CS.ClientType", 19);
                confServerProtocol.ClientName = userName;
                confServerProtocol.UserName = userName;
                confServerProtocol.UserPassword = password;

///////////But if I pass ConfServerProtocol in CreateEventBroker ... constructor it fails ///////////////
EventBrokerService brokerService = BrokerServiceFactory.CreateEventBroker(confServerProtocol);
///////// Arul's code trial //////////////////
[/code]

So after referring to the Developers guide , I thought of using a ProtocolManagementService , I get a message saying ' ProtocolManagementService' is going to be depreciated , and use warmstandby instead.. is it possible to use warmstandy along with CreateEventBroker ?

Please suggest if there is a better way or we can still stick to ProtocolManagementService' at this point.

Thanks
Arul

Hi Spin -- Thanks for pointing me towards the Eventhadling stuff ..
But I still have a doubt .. even if I handle the ..EventObjectsSent .. I can open a handler and to capture that and avoid case but still is there any other better methods which I can raise from this event handler to extract the one/more messages other way around.
Sorry I have no clue how to do that.. :( hence the ask.

Also I have started trying out hsujdik's option to see if I can get the details I wanted to retrieve.

Thanks
