---------------------------------
Summary: OAuth 2 Authorization support - Authorization Code Grant
Key: NIFI-4243
URL: https://issues.apache.org/jira/browse/NIFI-4243
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Jeremy Dyer
If your interacting with REST endpoints on the web chances are you are going to
run into an OAuth2 secured webservice. The IETF (Internet Engineering Task
Force) defines 4 methods in which OAuth2 authorization can occur. This JIRA is
focused solely on the Authorization Code Grant method defined at
https://tools.ietf.org/html/rfc6749#section-4.1
This implementation should provide a ControllerService in which the enduser can
configure the credentials for obtaining the authorization grant (access token)
from the resource owner. In turn a new property will be added to the InvokeHTTP
processor where the processor can reference this controller service to obtain
the access token and insert the appropriate HTTP header (Authorization: Bearer
{access_token}) so that the InvokeHTTP processor can interact with the OAuth
protected resources without having to worry about setting up the credentials
for each InvokeHTTP processor saving time and complexity.
