I wonder to send extract Attribute to ListenHTTP
Do you know how I write the rule from :
HTTP Headers to receive as Attributes (Regex) || Specifies the Regular Expression that determines the names of HTTP Headers that should be passed along as FlowFile attributes
My curl command :
curl -v --cacert nifi-cert.pem --cert ./client.p12 -X POST -H 'Content-Type: application/json' -H 'vartest1: v1' -F file=@/var/opt/hosting/log/flume/flume-a1.log.10 https://nifi012:10001/contentListener
How I can extract vartest1 as an attribute.
