             Summary: 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


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].
