Peter Turcsanyi created NIFI-6078:

             Summary: Create PostSlack processor
                 Key: NIFI-6078
                 URL: https://issues.apache.org/jira/browse/NIFI-6078
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Peter Turcsanyi


Implement a new PostSlack processor which is able to upload and attach the FlowFile content (eg. an image) to the Slack message.

The current PutSlack processor uses Slack Webhooks which have some limitations:
- file uploading not supported, only text messages (which can contain attachment links, but not the file to be uploaded itself)
- the current version of Slack Webhooks do not support the runtime configuration of Channel, Username, etc, parameters any more, so these properties of PutSlack have no effect

To overcome these limitations, the Slack Web API needs to be used instead of Webhooks. Due to this technology change, it is better to reimplement the functionality in a new processor than extending the existing one.
