How to keep the original flowfile?

Hello,
In the attached flow, the InvokeHTTP replaces the original flowfile. But the
SplitJSON needs the original flowfile instead of the flowfile given by the
InvokeHTTP. How to do that?

Thanks

Srini,

If you’re routing them to different processors, just drag another connection from the previous processor to the follow-on (this will keep the original flowfile) and route the response to whatever processor needs it.

I’ve attached a screenshot:

Hi Aldrin,
How can save the response to an attribute and at the same time keep the
original flowfile value. I think, I can either get response or original. How
to get both?

thanks
Srini

Hi Srini,

Depending on the typical size of the response, it is possible to store the
response in an attribute.  This would append the content onto the
previously existing FlowFile in an attribute of your choosing.

Hi Pierre,
But I want the response from InvokeHTTP also. How can I use the response and
keep the original flowfile so that SplitJson in the flow can use it.

thanks
Srini

Hi Srini,

You have a relationship "original" that will route the original flow file
used to perform the request. Have a look here:
https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi.processors.standard.InvokeHTTP/

Thanks
