Alios Media Offload moves your WordPress and WooCommerce media to Cloudflare R2 (or any S3-compatible bucket: Wasabi, Backblaze B2, DigitalOcean Spaces, MinIO, and more) and rewrites your site's media URLs to serve from your CDN domain. It signs AWS Signature V4 requests itself and sends them through the WordPress HTTP API — no bundled SDK, tiny footprint, works on PHP 7.4 through 8.3+. Features:

Cloudflare R2 and generic S3-compatible storage (endpoint / region / path-style).
Automatic offload of new uploads, with HEAD verification before marking complete.
Two-layer URL rewriting: per-attachment filters (always safe) plus an optional, opt-in full-page output-buffer rewrite for theme and page-builder embedded images.
Bulk migration of existing media (browser progress UI plus WP-CLI: wp r2mo migrate).
Guided 5-step setup wizard and one-click connection test.
Optional deletion of local copies after a verified upload.
Credentials can be set as wp-config.php constants (overriding the database).
Best-effort cache flush for popular cache plugins.
Optional, dismissible reminder to leave a review after a week of active use.

安装:

Upload the plugin to /wp-content/plugins/alios-media-offload and activate it.
Open Alios Offload > Setup Wizard, choose your provider, and enter your credentials, bucket, and Public Base URL.
Click Test connection.
Run Alios Offload > Migration to move existing media.
After migration shows 0 pending, enable Full-page URL rewriting in Settings. For best security, define your credentials in wp-config.php:

define('R2MO_ACCOUNT_ID', '...'); define('R2MO_ACCESS_KEY', '...'); define('R2MO_SECRET_KEY', '...'); define('R2MO_BUCKET', '...'); define('R2MO_ENDPOINT', '...'); // generic S3-compatible only define('R2MO_REGION', '...'); define('R2MO_PUBLIC_BASE', 'https://cdn.example.com');

1.1.3

Feature: After a week of use and at least one successful offload, a dismissible admin notice invites you to leave a 5-star review — with "maybe later" (30-day snooze) and "already reviewed" options.
Fix: satisfy the WordPress.Security.ValidatedSanitizedInput sniff in the wizard's settings-save AJAX handler (no behavior change).

1.1.2

Fix: the Setup Wizard now saves your provider, credentials, and options automatically as you move through each step, so "Test connection" always tests what you just entered instead of stale or empty settings.

1.1.1

Compliance: send storage requests through the WordPress HTTP API instead of cURL.
Privacy: documented the external storage service in the readme.
Fix: store secret/access keys without altering them; explicitly close the full-page output buffer on shutdown.

1.1.0

Feature: Added WP-Cron based Background Migration to allow offloading large libraries (e.g. 30,000+ files) asynchronously without keeping the browser tab open.
Feature: Redesigned Migration UI in admin area with two cards (Background and Browser migration).

1.0.1

Fix: Prevent uninstall.php from deleting _r2mo_offloaded post metadata during plugin deletion, preserving offload state on reinstall.

1.0.0

Initial release.
