kcfinder-client 0.2.0

Python client library for KCFinder file manager

kcfinder-client

A Python client library for KCFinder, a PHP web file manager. Wraps KCFinder's HTTP action-dispatch API into a clean Python interface with both async and sync clients.

[!NOTE] Designed for and tested against HarmonySite's KCFinder fork. May work with other KCFinder instances via SessionAuth, but this has not been tested.

Quick Start

Async (recommended)

import asyncio
import os
from kcfinder_client import AsyncKCFinderClient, HarmonySiteAuth

auth = HarmonySiteAuth(
    login_url="https://example.harmonysong.com/dbaction.php",
    browse_url="https://example.harmonysong.com/kcfinder/browse.php",
    username="admin",
    password="secret",
    bros_config=(
        'a:3:{s:9:"uploadDir";s:6:"files/";'
        's:9:"thumbsDir";s:14:"files/.thumbs/";'
        's:9:"uploadURL";s:0:"";}'
    ),
)

async def main():
    browse_url = "https://example.harmonysong.com/kcfinder/browse.php"
    async with AsyncKCFinderClient(browse_url, auth) as client:
        files = await client.list_files("banners")
        for f in files:
            print(f.name, f.size)

asyncio.run(main())

Sync

from kcfinder_client import KCFinderClient, HarmonySiteAuth

auth = HarmonySiteAuth(
    login_url="https://example.harmonysong.com/dbaction.php",
    browse_url="https://example.harmonysong.com/kcfinder/browse.php",
    username="admin",
    password="secret",
    bros_config=(
        'a:3:{s:9:"uploadDir";s:6:"files/";'
        's:9:"thumbsDir";s:14:"files/.thumbs/";'
        's:9:"uploadURL";s:0:"";}'
    ),
)

browse_url = "https://example.harmonysong.com/kcfinder/browse.php"
with KCFinderClient(browse_url, auth) as client:
    files = client.list_files("banners")
    for f in files:
        print(f.name, f.size)

Auth from Environment Variables

Load credentials from the environment rather than hardcoding them:

export KCFINDER_LOGIN_URL=https://example.harmonysong.com/dbaction.php
export KCFINDER_BROWSE_URL=https://example.harmonysong.com/kcfinder/browse.php
export KCFINDER_USERNAME=admin
export KCFINDER_PASSWORD=secret
export KCFINDER_BROS_CONFIG='a:3:{s:9:"uploadDir";s:6:"files/";s:9:"thumbsDir";s:14:"files/.thumbs/";s:9:"uploadURL";s:0:"";}'

import os
from kcfinder_client import AsyncKCFinderClient, harmonysite_auth_from_env
import asyncio

async def main():
    auth = harmonysite_auth_from_env()
    browse_url = os.environ["KCFINDER_BROWSE_URL"]
    async with AsyncKCFinderClient(browse_url, auth) as client:
        files = await client.list_files()
        print(f"Found {len(files)} files")

asyncio.run(main())

Sync Files with SyncManager

One-way push sync to make a remote directory match a local one:

import os
from pathlib import Path
from kcfinder_client import KCFinderClient, SyncManagerSync, harmonysite_auth_from_env

auth = harmonysite_auth_from_env()
browse_url = os.environ["KCFINDER_BROWSE_URL"]

with KCFinderClient(browse_url, auth) as client:
    sync = SyncManagerSync(client)

    # Dry run first to preview changes
    result = sync.push("banners", Path("./banners"), dry_run=True)
    print(f"Would upload: {result.uploaded}")
    print(f"Would delete: {result.deleted}")
    print(f"Would skip:   {result.skipped}")

    # Apply the sync
    result = sync.push("banners", Path("./banners"))
