webservice needs to get sessionid with 2 different URL’s

[Donna Bailey]

Has anyone ever had to set up a webservice using the HTTP protocol to get a Session ID and then send that Session ID back in message with the data?  Vendor is telling me the URL is different for each process.  I have a script I’ve used on another interface, but didn’t need the Session ID.

I’m on windows using CL 5.8..

Any thoughts, suggestions, etc??

Thanks,

Donna

Does the session ID come back in an XML file?

Hmm, and in that XML file, is the HL7 message also in the same XML file?

I’ve never done this before, just thinking out loud..

You know what…when I finally was able to get the sessionID..it’s coming back in xml….so now I’m trying to get the other piece working…and having issues with getting the data to them.

But after I get that to work..I’m going to need a way to connect the 2 threads..1.thread that retrieves the session id.  2.  Thread that gets the session id info from thread 1 and sends that along to vendor with the result data…

Lots of fun!!

Any thoughts?

Thanks,

Donna

Donna,

Our approach to something like this is to save the original message into metadata and chain threads together.  Use the first thread to get the Session ID and save it to metadata also.  Pull in the original message from metadata and add the Session ID as needed, then pass it on to your destination using another thread.  Tcl is definitely required.

Tcl procs that read or update metadata from inside a translate make the whole process more straight-forward.

I need to take the message and the session ID and send route it to another thread…how do I get these message handles to do that?  I was trying to use disposition OVER?  But now my message is “stuck” on the middle thread..

We do something similar and run this code on the “middle” thread in the outbound TPS:

Code:

           keylget args MSGID mh
           msgmetaset $mh SOURCECONN $::HciConnName
           lappend dispList “OVER $mh”

We use something based on the following for the reply handling to pass the original message on with the info in the USERDATA.

The below retries if it fails, or passes the message on if its ok. Please note it may have typos in it.

Code:

proc session_reply {args} {
   global HciConnName
   keylget args MODE       aMode
   keylget args MSGID      aMsgId
   keylget args CONTEXT    aContext
   keylget args ARGS       aArg

.
.
.
   if {[string equal $aMode run]} {
       set myDispList {}
       switch $aContext {
           sms_ib_reply {
               set myFail 0
.
.
.
               if {(!$myFail) && [keylget args OBMSGID myObMsgId]} {
                   set myMsgId [msgcopy $myObMsgId]
                   msgmetaset $myMsgId DESTCONN {} SOURCECONN $HciConnName USERDATA $myUserData
                   lappend myDispList “CONTINUE $myMsgId”
               } else {
                   set myFail 1
               }
               if {!$myFail} {
                   lappend myDispList “KILLREPLY $aMsgId”
               } else {
                   lappend myDispList “KILL $aMsgId”
               }

           }
       }
       return $myDispList
   }
}

Elisha,

Thank you for the information…it looks exactly what I need to do…Where do you put your proc?

This goes in the TPS Inbound Reply of the Outbound properties.

If you only need to get a new session id on startup or predefined intervals, you could also save the session id somewhere, then use the TPS Outbound Data (sms_ob_data) to check if the session id is ok, then use OVER as per David’s message. I believe this skips the call to get the session id.

[Donna Bailey]

Session ID gets reset about every hour…I couldn’t get the chaining of threads to work..so I went with outputting a file and then will pick it up with fileset-local to send data to vendor….in a crunch..so have to go with what I know…

Thanks all for you input.
