Re: [Ftpapi] http_persist_req(PUT:pointer:...) return error of HTTP/1.1 411 Length Required

Hello,
There is a bug in HTTPAPI that will be fixed in the next release. The bug is explained here: 
http://www.scottklement.com/archives/ftpapi/201702/msg00004.html

So to fix this problem you must:
1) Change the code as described in the link above (or wait for the next release.)
2) Change your call to http_persist_req() to pass a non-null pointer for the peUplData parameter. (A null indicates that your request does not have any request document to send -- which is incorrect for a PUT request.) 

Once both of these changes have been made, it should work as expected.

Hi Scott,
The following is what i'm encountering by using the http_persist_req with 'PUT' to consume a rest service. This is how my RPGLE program looks like :- 


DPointer S *

        http_setCCSIDs(1208:0);
        http_debug(*ON:'/tmp/InvoiceOfCustomerOrderLineReleased.txt');
        requestUri ='http://srvwebuat:8030/OrderProcessingWfV1/+
api/CustomerOrderLine/1-2-3/ClosedOrDeleted';

         pointer =http_persist_open(requestUri);
if(pointer =*null);
     Display_Text(http_error);
endif;

rc =http_persist_req('PUT':pointer:requestUri
:0:*null:
*null:0:0:%paddr(mySaveProc):300:
'application/json');

http_persist_close(Pointer);

Getting back rc = 411 and the debug log shows the following :-
