Adam Debreceni reassigned MINIFICPP-1831:
-----------------------------------------
Assignee: Adam Debreceni
> C2 asset download command
> -------------------------
>
> Key: MINIFICPP-1831
> URL: https://issues.apache.org/jira/browse/MINIFICPP-1831
> Project: Apache NiFi MiNiFi C++
> Issue Type: New Feature
> Reporter: Marton Szasz
> Assignee: Adam Debreceni
> Priority: Major
>
> Story: As a minifi user, I want to push files to my agents from a central C2
> server, and reference them later in the flow. E.g. pushing a python script,
> and after ACK, updating the flow with an ExecuteScript to use that python
> script.
>
> Technical details:
> As a security measure, we need a new property for the asset path, which
> defaults to MINIFI_HOME/asset, and we need to place all assets in that
> directory.
> The functionality is an extension to the UPDATE C2 operation, under a new
> download-file operand. Example operation:
> {code:java}
> "requestedOperations": [
> {
> "identifier": "8678316c-d4fd-493b-9177-454a0d65d7fd",
> "operation": "UPDATE",
> "operand": "download-asset",
> "args": {
> "file": "my_script.py",
> "url": "/c2/api/asset/472a0346-4b6b-11ec-9a48-0242ac11000c",
> "checksum": "120EA8A25E5D487BF68B5F7096440019",
> "forceDownload": "false"
> },
> "dependencies": []
> }
> ]{code}
> The meaning of forceDownload: If a file with the specified name already
> exists in the asset directory, we overwrite it if forceDownload, otherwise we
> reply with NO_OPERATION.
> If the URL is relative, it's treated as relative to the base path of the
> heartbeat url, under the asset directory. I.e. if the C2 heartbeat goes to
> [http://myc2:1234/c2/heartbeat] and file="my_script.py", then we download
> [http://myc2:1234/c2/asset/my_script.py|http://myc2:1234/c2/assets/my_script.py].
