Hi, I'm trying to access a SOAP webservice that only seems to recognize Transfer-Encoding: chunked requests. Does Rollbase support this type of HTTP transmission for POST requests? Thanks!
Do you mean WSDL encoding?
I'm trying to use the HTTP POST trigger documented in Chapter 10 to send data contained in an XML template associated with the trigger. It is a Login request. The remote service (controlled by a third party) only responds to Transfer-Encoding: chunked requests.
Although the request I'm sending is only one chunk, the remote side does not seem to respond when the Content-Length header is supplied to indicate the size of the request body. It seems to need the value (in hexadecimal) prepended to the XML template, and terminated with a null character (0). When this is done manually (and specify the HTTP Header "Transfer-Encoding: chunked") the request goes through ok.
The main problem I am having is that the merge tokens in the XML template will cause the size to be adjusted with each different SOAP Login request to the 3rd party service. I will not be able to specify an optimal value for the chunk size after the merge tokens have been substituted. I don't think I have a way to do that at the moment.
Hi,
Try this: Create a formula field on the same object, return type int; input your XML code in a variable, var xmlCode = "xml template"... dont forget to escape chars if needed, or convert double quotes (") to single quotes (') so that it's a valid Js string.
The XML code inside should also include your merge tokens so you can compute the length dynamically.
Then return the length as an int return xmlCode.length; on your formula field.
Then you can manipulate to return the Hex value.
Hope this helps,

I'll add "chunked transfer" option in the next release (this weekend).
This is such a creative solution! Thanks for your input! :)
Thank you, sir!
