aria2p 0.1.1

Command-line tool and library to interact with an aria2c daemon process with JSON-RPC.

Aria2p

Command-line tool and Python library to interact with an aria2c daemon process through JSON-RPC.

Installation

No packaging yet. Clone the repo and install requests with [sudo] pip install requests, or create a dedicated Python virtualenv with Python 3.6.

Usage (as a library)

This library is still a work in progress. Some things listed here might not be implemented yet.

import aria2p

# initialization, these are the default values
aria2 = aria2p.API(
    aria2p.JSONRPCClient(
        host="http://localhost",
        port=6800,
        secret=""
    )
)

# list downloads
downloads = aria2.get_downloads()

for download in downloads:
    print(download.name, download.download_speed)
    
# add downloads
magnet_uri = "magnet:?xt=urn:..."

download = aria2.add_magnet(magnet_uri)

Usage (command-line)

For now, the command-line tool can only call methods using the client. More options directly using the API will come later.

./aria2p.py -m,--method METHOD_NAME [-p,--params PARAMS... | -j,--json-params JSON_STRING]

The METHOD_NAME can be the exact method name, or just the name without the prefix. It is case-insensitive, and dashes and underscores will be removed. The following are all equivalent:

• aria2.addUri
• aria2.adduri
• addUri
• ADDURI
• aria2.ADD-URI
• add_uri
• A-d_D-u_R-i (yes it's valid)
• A---R---I---A---2.a__d__d__u__r__i (I think you got it)
• and even more ugly forms...

Examples

List all available methods. This example uses jq.

$ ./aria2p.py -m listmethods | jq
[
  "aria2.addUri",
  "aria2.addTorrent",
  "aria2.getPeers",
  "aria2.addMetalink",
  "aria2.remove",
  "aria2.pause",
  "aria2.forcePause",
  "aria2.pauseAll",
  "aria2.forcePauseAll",
  "aria2.unpause",
  "aria2.unpauseAll",
  "aria2.forceRemove",
  "aria2.changePosition",
  "aria2.tellStatus",
  "aria2.getUris",
  "aria2.getFiles",
  "aria2.getServers",
  "aria2.tellActive",
  "aria2.tellWaiting",
  "aria2.tellStopped",
  "aria2.getOption",
  "aria2.changeUri",
  "aria2.changeOption",
  "aria2.getGlobalOption",
  "aria2.changeGlobalOption",
  "aria2.purgeDownloadResult",
  "aria2.removeDownloadResult",
  "aria2.getVersion",
  "aria2.getSessionInfo",
  "aria2.shutdown",
  "aria2.forceShutdown",
  "aria2.getGlobalStat",
  "aria2.saveSession",
  "system.multicall",
  "system.listMethods",
  "system.listNotifications"
]

List the GIDs (identifiers) of all active downloads. Note that we must give the parameters as a JSON string.

$ ./aria2p.py -m tellactive -j '[["gid"]]'
[{"gid": "b686cad55029d4df"}, {"gid": "4b39a1ad8fd94e26"}, {"gid": "9d331cc4b287e5df"}, {"gid": "8c9de0df753a5195"}]

Pause a download using its GID. Note that when a single string argument is required, it can be passed directly with -p.

$ ./aria2p.py -m pause -p b686cad55029d4df
"b686cad55029d4df"

Add a download using magnet URIs. This example uses jq -r to remove the quotation marks around the result.

$ ./aria2p.py -m adduri -j '[["magnet:?xt=urn:..."]]' | jq -r
4b39a1ad8fd94e26f

Purge download results (remove completed downloads from the list).

$ ./aria2p.py -m purge_download_result
"OK"
