Hello Eduard,

i was able to convert the HttpResponse.Data to String and than to the Dynamic Object. Worked great. Thank you.

On the same line, i need to ask you of any template or suggestion to send a JSON data to a REST API.

For eg. below is the JSON

{"name":"abcdefghi","salary":"123","age":"23"}

How do i send it to  http://testing.restapiexample.com/api/v1/createemployee with POST request using the  set tSC=..Adapter.PostURL(tConfig.URL,.tHTTPResponse,,pRequest)

Below code is not working.

Set pRequest=."{"name":"abcdefghi","salary":"123","age":"23" }"

Your help will be appreciated.

Thanks,

Jimmy Christian.

Yes, Thank you. I just corrected the URL and it works now. Thank you Robert.  One more question if you can assist in this context.

So the response message i got back is in the HttpResponse object.

How can i convert the HttpResponse.Data property to JSON and parse the values. Since the data i received is Stream, is there a way i can convert the stream to Dynamic Objects and parse  it?

Thank you.

Jimmy Christian.

Thank you Marc. Looks like this  Issue is resolved . Appreciate your input.

Yes, I did. 

       set tRequest=##class(Ens.StreamContainer).%New(pInput)
      do tRequest.%Save()
      set tSC = ..SendRequestAsync(..TargetConfigNames,tRequest)

Thanks,

Jimmy Christian.

Hello Eduard,

I used %Stream.FileCharacter to resolve the error on Operation which is complaining that "No Stream contained in StreamContainer Request".

I am going to use the JSON serialization once i  refer to some document about it. 

Thank you for help.

Jimmy Christian.

Thank you Aldo for checking this out. I tried to make it much simpler by using what you suggested. I was hoping the operation to  accept it since pInput is a Stream.

But still the same error. Operation does not find STREAM in the ENS. StreamContainer.

Class Hospital.ApptListFileService Extends Ens.BusinessService
{
Parameter ADAPTER = "EnsLib.File.InboundAdapter";
Parameter SETTINGS = "TargetConfigNames";
Property TargetConfigNames As Ens.DataType.ConfigName;
Property SentMsg As %FileCharacterStream;

Method OnProcessInput(pInput As %FileCharacterStream, Output pOutput As %RegisteredObject) As %Status
{
set tSC = $$$OK
    set pInput.LineTerminator=$c(10)
try 
{
while 'pInput.AtEnd {
          do pInput.ReadLine()
         
          set tRequest=##class(Ens.StreamContainer).%New(pInput)
  
          set tSC = ..SendRequestAsync(..TargetConfigNames,tRequest)
}

Thank you Stephen. I will check the link you provided for more understanding on REST.

Hello Evgeny,

Yes this worked perfectly. I think i did select %ALL role, but did not click on assign but only SAVED it.

Thank you for all your help. But looks like at some point once i familiarize myself with this web and rest app build, i will need to learn more about security..

Thanks,

Jimmy Christian.

Thank you Nigel for the suggestions. Agreed, but since this is just a standalone training env, and for now i only want to have a hands on REST development, i think assigning %All role should be fine to see the output of the code ! Security will be my next hands on once i am familiar with the REST architecture.

Yep. Select INTO works great if the source and target tables are in same NAMESPACE. I need to copy the data across namespaces, for which i  have already some another method. 

But i found that copying recordset would also work, since once the object is created i can easily write to another table on a different "NAMESPACE". Only issue is to write to a target table from a recordset i need to loop it and am not aware of a straightforward copy.

Thank you Robert. But looks like i am running into another issue where data is lost and i am unable to create table.

I really would prefer to find out if there is a way to copy directly a RecordSet to a table or any other faster method rather than looping through the entire Recordset.

Vitaliy, This is great !

The code works fine now. Appreciate your help and time.

I have to put some filters on the columns now, which i think i have to use the QueryInfo Object.

Thank you !

Regards,

Jimmy Christian.

Hello Vitaliy,

Thank you for your time. This works good. Issue is that i only see the first page of the results.

Even after adding the tableNavigatorBar, it still shows only one page  and not all the results. I have more than 30,000 rows to display on the page. Let me know.

Thanks,

Jimmy

I cannot share globals on the namepsace i am working on.

Actually i was able to retrieve data from Namespace2  working on a callback method for recordset which the table  is using. But now issue is zenpage only shows the first page.

Will try to find out a reason why the page is hanging. It could be that i have to flip back to Namespace1 once i get the recordset.

Thanks.

Thanks Neerav.

I am referring to the zenpage call back methods, which are called on a zenpage event.

Problem is i cannot create any views in namespace2.

Thanks Neerav.

I still believe  we can do in the code by using a callback method. I am not sure how to use it.

Thanks John. This was helpful. I had to correct the password for that service.

Issue is resolved.

Thank you . This is perfect !

I just tweaked it little bit

SET testingddl="CREATE TABLE xxxxxxx"_$USERNAME_"(TNAMESPACE CHAR(100),TINTERFACE CHAR(100),TPORT INT)"
s  ret=##class(%SQL.Statement).%ExecDirect(,.testingddl)
 

Thank you all. At this time, i will not be able to map the USER db to rest of it. But i will try to call support .
