Consume API with Nifi-Token authentication

foivos — Fri, 06 Oct 2017 22:26:19 GMT

I want to create a Nifi flow with GET requests to a REST API that supports authorization via a Bearer token, however i have problems to create the proper flow due to the several available HTTP-related processors in Nifi.

My question is which is the proper flow to do this?

I tried the flow GetHTTP --> Update Attribute --> PutHDFS to store also the results in HDFS after the filename is appended with a timestamp but i could not find a way to properly configure the GetHTTP processor for the token authorization.

The flow InvokeHTTP --> UpdateAttribute --> PutHDFS also didnt work for me, setting the Send Attributes =Authorization and adding the token as value to the newly created Authorization property fails with a "Yielding processor due to exception encountered as source processor" error. Any ideas on how could i proceed with this? Thanks in advance!

I found a way to create empty flowfiles, update the attributes with proper authorization headers and send the request with InvokeHTTP.
