## 描述

Enter the fediverse with **ActivityPub**, broadcasting your blog to a wider audience!
Attract followers, deliver updates, and receive comments from a diverse user base
of **ActivityPub**-compliant platforms.

With the ActivityPub plugin installed, your WordPress blog itself functions as a
federated profile, along with profiles for each author. For instance, if your website
is `example.com`, then the blog-wide profile can be found at `@example.com@example.
com`, and authors like Jane and Bob would have their individual profiles at `@jane@example.
com` and `@bob@example.com`, respectively.

An example: I give you my Mastodon profile name: `@pfefferle@mastodon.social`. You
search, see my profile, and hit follow. Now, any post I make appears in your Home
feed. Similarly, with the ActivityPub plugin, you can find and follow Jane’s profile
at `@jane@example.com`.

Once you follow Jane’s `@jane@example.com` profile, any blog post she crafts on `
example.com` will land in your Home feed. Simultaneously, by following the blog-
wide profile `@example.com@example.com`, you’ll receive updates from all authors.

**Note**: If no one follows your author or blog instance, your posts remain unseen.
The simplest method to verify the plugin’s operation is by following your profile.
If you possess a Mastodon profile, initiate by following your new one.

The plugin works with the following tested federated platforms, but there may be
more that it works with as well:

 * [Mastodon](https://joinmastodon.org/)
 * [Pleroma](https://pleroma.social/)/[Akkoma](https://akkoma.social/)
 * [friendica](https://friendi.ca/)
 * [Hubzilla](https://hubzilla.org/)
 * [Pixelfed](https://pixelfed.org/)
 * [Socialhome](https://socialhome.network/)
 * [Misskey](https://join.misskey.page/)

Some things to note:

 1. The blog-wide profile is only compatible with sites with rewrite rules enabled.
    If your site does not have rewrite rules enabled, the author-specific profiles 
    may still work.
 2. Many single-author blogs have chosen to turn off or redirect their author profile
    pages, usually via an SEO plugin like Yoast or Rank Math. This is usually done 
    to avoid duplicate content with your blog’s home page. If your author page has 
    been deactivated in this way, then ActivityPub author profiles won’t work for you.
    Instead, you can turn your author profile page back on, and then use the option
    in your SEO plugin to noindex the author page. This will still resolve duplicate
    content issues with search engines and will enable ActivityPub author profiles 
    to work.
 3. Once ActivityPub is installed, _only new posts going forward_ will be available
    in the fediverse. Likewise, even if you’ve been using ActivityPub for a while, 
    anyone who follows your site will only see new posts you publish from that moment
    on. They will never see previously-published posts in their Home feed. This process
    is very similar to subscribing to a newsletter. If you subscribe to a newsletter,
    you will only receive future emails, but not the old archived ones. With ActivityPub,
    if someone follows your site, they will only receive new blog posts you publish
    from then on.

So what’s the process?

 1. Install the ActivityPub plugin.
 2. Go to the plugin’s settings page and adjust the settings to your liking. Click 
    the Save button when ready.
 3. Make sure your blog’s author profile page is active if you are using author profiles.
 4. Go to Mastodon or any other federated platform, and search for your profile, and
    follow it. Your new profile will be in the form of either `@your_username@example.
    com` or `@example.com@example.com`, so that is what you’ll search for.
 5. On your blog, publish a new post.
 6. From Mastodon, check to see if the new post appears in your Home feed.

**Note**: It may take up to 15 minutes or so for the new post to show up in your
federated feed. This is because the messages are sent to the federated platforms
using a delayed cron. This avoids breaking the publishing process for those cases
where users might have lots of followers. So please don’t assume that just because
you didn’t see it show up right away that something is broken. Give it some time.
In most cases, it will show up within a few minutes, and you’ll know everything 
is working as expected.

## 安装

Follow the normal instructions for [installing WordPress plugins](https://wordpress.org/support/article/managing-plugins/).

#### Automatic Plugin Installation

To add a WordPress Plugin using the [built-in plugin installer](https://codex.wordpress.org/Administration_Screens#Add_New_Plugins):

 1. Go to [Plugins](https://codex.wordpress.org/Administration_Screens#Plugins) > [Add New](https://codex.wordpress.org/Plugins_Add_New_Screen).
 2. Type “`activitypub`” into the **Search Plugins** box.
 3. Find the WordPress Plugin you wish to install.
 4.  a. Click **Details** for more information about the Plugin and instructions you may
        wish to print or save to help setup the Plugin.

 5. The resulting installation screen will list the installation as successful or note
    any problems during the install.
 6. If successful, click **Activate Plugin** to activate it, or **Return to Plugin 
    Installer** for further actions.

#### Manual Plugin Installation

There are a few cases when manually installing a WordPress Plugin is appropriate.

 * If you wish to control the placement and the process of installing a WordPress
   Plugin.
 * If your server does not permit automatic installation of a WordPress Plugin.
 * If you want to try the [latest development version](https://github.com/pfefferle/wordpress-activitypub).

Installation of a WordPress Plugin manually requires FTP familiarity and the awareness
that you may put your site at risk if you install a WordPress Plugin incompatible
with the current version or from an unreliable source.

Backup your site completely before proceeding.

To install a WordPress Plugin manually:

 * Download your WordPress Plugin to your desktop.
    - Download from [the WordPress directory](https://wordpress.org/plugins/activitypub/)
    - Download from [GitHub](https://github.com/pfefferle/wordpress-activitypub/releases)
 * If downloaded as a zip archive, extract the Plugin folder to your desktop.
 * With your FTP program, upload the Plugin folder to the `wp-content/plugins` folder
   in your WordPress directory online.
 * Go to [Plugins screen](https://codex.wordpress.org/Administration_Screens#Plugins)
   and find the newly uploaded Plugin in the list.
 * Click **Activate** to activate it.

## 常见问题

### tl;dr

This plugin connects your WordPress blog to popular social platforms like Mastodon,
making your posts more accessible to a wider audience. Once installed, your blog
can be followed by users on these platforms, allowing them to receive your new posts
in their feeds.

### What is “ActivityPub for WordPress”

_ActivityPub for WordPress_ adds Fediverse features to WordPress, but it is not 
a replacement for platforms like Friendica or Mastodon. If you’re looking to host
a decentralized social network, consider using [Mastodon](https://joinmastodon.org/)
or [Friendica](https://friendi.ca/).

### Why “ActivityPub”?

The name ActivityPub comes from the two core ideas behind the protocol:

 * Activity: It is based on the concept of activities, like “Create”, “Like”, “Follow”,“
   Announce”, etc. These are structured messages (usually in [ActivityStreams](https://www.w3.org/TR/activitystreams-core/)
   format) that describe what users do on the network.
 * Pub: Short for publish or publication. It refers to the fact that this is a publish-
   subscribe (pub-sub) protocol — one user can “follow” another, and receive their
   published activities.

Put together, ActivityPub is a protocol for publishing and subscribing to activities,
which enables decentralized social networking — where different servers can interact
and users can follow each other across the Fediverse.

### How do I solve…

We have a **How-To** section in the [docs](https://github.com/Automattic/wordpress-activitypub/tree/trunk/docs/how-to)
directory that can help you troubleshoot common issues.

### Constants

The plugin uses PHP Constants to enable, disable or change its default behaviour.
Please use them with caution and only if you know what you are doing.

 * `ACTIVITYPUB_REST_NAMESPACE` – Change the default Namespace of the REST endpoint.
   Default: `activitypub/1.0`.
 * `ACTIVITYPUB_EXCERPT_LENGTH` – Change the length of the Excerpt. Default: `400`.
 * `ACTIVITYPUB_MAX_IMAGE_ATTACHMENTS` – Change the number of attachments, that 
   should be federated. Default: `4`.
 * `ACTIVITYPUB_HASHTAGS_REGEXP` – Change the default regex to detect hashtext in
   a text. Default: `(?:(?<=\s)|(?<=<p>)|(?<=<br>)|^)#([A-Za-z0-9_]+)(?:(?=\s|[[:
   punct:]]|$))`.
 * `ACTIVITYPUB_USERNAME_REGEXP` – Change the default regex to detect @-replies 
   in a text. Default: `(?:([A-Za-z0-9\._-]+)@((?:[A-Za-z0-9_-]+\.)+[A-Za-z]+))`.
 * `ACTIVITYPUB_URL_REGEXP` – Change the default regex to detect urls in a text.
   Default: `(www.|http:|https:)+[^\s]+[\w\/]`.
 * `ACTIVITYPUB_CUSTOM_POST_CONTENT` – Change the default template for Activities.
   Default: `<strong>[ap_title]</strong>\n\n[ap_content]\n\n[ap_hashtags]\n\n[ap_shortlink]`.
 * `ACTIVITYPUB_AUTHORIZED_FETCH` – Enable AUTHORIZED_FETCH.
 * `ACTIVITYPUB_DISABLE_REWRITES` – Disable auto generation of `mod_rewrite` rules.
   Default: `false`.
 * `ACTIVITYPUB_DISABLE_INCOMING_INTERACTIONS` – Block incoming replies/comments/
   likes. Default: `false`.
 * `ACTIVITYPUB_DISABLE_OUTGOING_INTERACTIONS` – Disable outgoing replies/comments/
   likes. Default: `false`.
 * `ACTIVITYPUB_DISABLE_REMOTE_CACHE` – Disable remote media caching (avatars, media,
   emoji). Default: `false`. Replaces `ACTIVITYPUB_DISABLE_SIDELOADING` from 7.9.1.
 * `ACTIVITYPUB_SHARED_INBOX_FEATURE` – Enable the shared inbox. Default: `false`.
 * `ACTIVITYPUB_SEND_VARY_HEADER` – Enable to send the `Vary: Accept` header. Default:`
   false`.

### Where can you manage your followers?

If you have activated the blog user, you will find the list of his followers in 
the settings under `/wp-admin/options-general.php?page=activitypub&tab=followers`.

The followers of a user can be found in the menu under “Users” -> “Followers” or
under `wp-admin/users.php?page=activitypub-followers-list`.

For reasons of data protection, it is not possible to see the followers of other
users.

Great plugin with regular updates. Does what it says on the label, and does it well.
It makes my WP posts look great in the fediverse and boost, replies, and likes quickly
make their way back to my site.

As someone working on the Korean translation of this plugin, I have seen first-hand
how important it is for WordPress users to connect with the Fediverse. This plugin
provides a bridge that makes such integration possible. Thanks to the developers,
Korean users can now more easily explore and join the open social web. I deeply 
appreciate the effort, vision, and continuous improvements behind this project.

I’ve installed and setup other ActivityPub servers usually some time & testing required
along with tweaks. However with the WP ActivityPub plug-in it, surprisingly, functioned
properly <gasp!> right after install. What a joy. Thank you.

Great plugin (actively maintained!), great support, a very nice way to join the 
Fediverse and automatically share posts and any kind of CPT to the Fediverse audience.
I was initially sharing posts using my personal Mastodon account, but it’s much 
nicer to have your dedicated account for your blogs (and/or authors). Thanks for
this plugin!

Why wouldn’t you want your blog to federate with Mastodon and all the other apps
on the Fediverse? This plugin in such an important piece in the social web ecosystem.
Install eyes closed.

## 更新日志

### 8.2.1 – 2026-05-01

#### Security

 * Hardened how the inbox processes large recipient lists in incoming activities.

#### Fixed

 * Fix monthly and annual Fediverse Stats emails being sent more than once per period
   when the scheduler ran multiple times.

### 8.2.0 – 2026-04-27

#### Security

 * ActivityPub REST endpoints no longer advertise credentialed cross-origin access.
   Browser-based clients using OAuth bearer tokens continue to work as before.
 * Aligned the deprecated signature verifier’s clock tolerance with the supported
   verifiers.
 * Blocked additional reserved IPv6 ranges from outbound request safety checks.
 * Decoded percent-encoded forms in the follower sync authority before the safety
   check.
 * Fail closed when an OAuth request can’t be tied to a client IP, instead of sharing
   one rate-limit bucket.
 * Hardened input handling for incoming federated activity types.
 * Hardened outbound request handling for third-party app connections and live activity
   streams.
 * Hardened outbound request safety to cover IPv6-only third-party hosts.
 * Per-IP rate limits now only trust the actual TCP peer by default, so an attacker
   on a directly-exposed site cannot bypass the cap by spoofing X-Forwarded-For 
   or similar proxy headers. Sites behind a trusted reverse proxy (Cloudflare, Akamai,
   nginx) can opt the relevant header back in via the new “activitypub_client_ip_sources”
   filter.
 * Reject follower sync requests targeted at internal-network hosts at the route
   layer.
 * Required signatures on HEAD requests to peer-only endpoints.

#### Changed

 * Development tooling: require PHPUnit 9.6.33 or newer (security fix CVE-2026-24765).
   No runtime impact for end users.
 * OAuth public clients must now use PKCE by default, matching OAuth 2.1. Site operators
   can relax this via the activitypub_oauth_require_pkce filter if legacy clients
   need to connect.
 * Returned the standard rate-limit response from the OAuth token endpoint when 
   too many requests are sent.

#### Fixed

 * Delete activities no longer bypass signature verification on endpoints that explicitly
   require it.
 * OAuth token revocation now verifies the caller owns the token being revoked.
 * Tighten HTTP signature verification: narrow the clock-skew window, reject signatures
   that carry no freshness timestamp, and cap unreasonable expiry times. Peers that
   sign without a Date or creation timestamp will no longer verify.
 * Trim dev-only configuration files from the plugin release package.

### 8.1.1 – 2026-04-22

#### Added

 * Added the `activitypub_post_object_type` filter so plugins can override the federated
   object type (Note, Article, Page) for a post.

#### Changed

 * Always flush rewrite rules at the end of a plugin migration so that users upgrading
   across multiple versions do not miss a flush.

#### Fixed

 * Fix the Fediverse stats widget on sites where the REST namespace is remapped,
   such as WordPress.com.
 * Harden the reactions API response so stored author names and URLs cannot introduce
   markup or non-HTTP schemes into the JSON output.
 * Stop hiding posts that contain a federated reply block from the main blog listing
   and the admin post list on sites that do not use the Posts and Replies block.

### 8.1.0 – 2026-04-21

#### Security

 * Add rate limiting to app registration to prevent abuse.
 * Fix blog actor outbox exposing private activities to unauthenticated visitors.
 * Restrict localhost URL allowance to local development environments only.
 * Verify that the signing key belongs to the same server as the activity actor.

#### Added

 * Add a “Posts and Replies” tab bar for author archives that filters between posts
   and replies, similar to Mastodon’s profile view.
 * Add a liked collection to actor profiles, showing all posts the actor has liked.
 * Add a seasonal starter pattern that suggests sharing Fediverse stats when creating
   a new post in December and January.
 * Add a stats block that displays annual Fediverse statistics as a card on the 
   site and as a shareable image on the Fediverse, with automatic color and font
   adoption from the site’s theme.
 * Added `activitypub_pre_get_by_id` filter to allow plugins to register custom 
   virtual actors resolved by ID.
 * Add EXIF metadata support for image attachments using Vernissage namespace.
 * Add new Fediverse Following Page and Profile Page block patterns.
 * Add OAuth server metadata and registration endpoint discovery to actor profiles.
 * Add real-time streaming for inbox and outbox updates via Server-Sent Events (
   SSE).
 * Add support for Block, Add (pin post), and Remove (unpin post) activities via
   Client-to-Server API.
 * Add support for check-in activities posted via compatible apps.
 * Add support for importing Starter Packs in both the Pixelfed and Mastodon formats.
 * Add tags.pub integration to supplement tag timelines with posts from across the
   Fediverse.
 * Support for ActivityPub Client-to-Server (C2S) protocol, allowing apps like federated
   clients to create, edit, and delete posts on your behalf.

#### Changed

 * Block patterns for follow, following, and profile pages are now only suggested
   when editing pages.
 * Fix notification pagination when using Enable Mastodon Apps: use date-constrained
   queries instead of truncating the shared notification pool, and expose `$limit`,`
   $before_date`, and `$after_date` as additional filter arguments so third-party
   handlers can fetch the correct window.
 * Improve the pre-publish format suggestion panel with clearer messages and a confirmation
   after applying a format.
 * Podcast episodes now respect the configured object type setting instead of always
   being sent as “Note”.
 * Show reaction action buttons even when a post has no reactions yet.

#### Fixed

 * ActivityPub endpoints that surface comment, reply, like, share, and remote-reply
   metadata now honor the parent post’s visibility setting.
 * Added validation for SSE access tokens passed via query parameter.
 * Fix account migration (Move) not working when moving back to an external account.
 * Fix a fatal error during activity delivery when the outbox item has been deleted.
 * Fix a fatal error when receiving activities with a non-string language property.
 * Fix a fatal `array_keys(null)` in `Comment::get_comment_type_slugs()` that could
   take down any request where a third-party plugin transitioned a custom comment
   type before `add_comment_type()` had been called.
 * Fix a missing script dependency notice on the admin page in WordPress 6.9.1 and
   later.
 * Fix BuddyPress @mention filter corrupting Fediverse Followers and Following blocks.
 * Fix cleanup jobs silently doing nothing on sites where purge retention options
   were not set.
 * Fix comments on remote posts being incorrectly held in moderation.
 * Fix double-encoded HTML entities in post titles on the Fediverse Stats dashboard.
 * Fixed an issue where quote authorization stamps could reference unrelated posts.
 * Fixed double-encoding of special characters in comment author names on updates.
 * Fixed emoji shortcode replacement to handle special characters in emoji names
   correctly.
 * Fix fatal error when other plugins hook into the user agent filter expecting 
   two arguments.
 * Fix Fediverse Preview showing the standard web view instead of the ActivityPub
   preview for draft posts.
 * Fix OAuth authentication failing for local development clients using localhost
   subdomains.
 * Fix performance regression from reply-exclusion filter by skipping it for queries
   targeting non-ActivityPub post types.
 * Fix Reader feed failing to load with newer WordPress versions.
 * Fix remote actor avatars getting stuck on broken URLs when the original image
   becomes unavailable.
 * Fix Site Health check showing an empty error message when the WebFinger endpoint
   is not reachable.
 * Fix the Fediverse profile “Joined” date showing the oldest post date instead 
   of when the site started federating.
 * Fix the Fediverse profile showing an inflated post count by excluding incoming
   comments from the total.
 * Fix Update handler using stale local actor data instead of the activity payload
 * Improved HTTP Signature validation for requests with a missing Date header.
 * Only allow S256 as PKCE code challenge method for OAuth authorization.
 * Prevent third-party plugin UI elements and scripts from appearing in federated
   content.
 * Require signed peer requests for the followers synchronization endpoint per FEP-
   8fcf.
 * Show a styled error page instead of raw technical output when an OAuth application
   cannot be reached during authorization.
 * Strip private recipient fields from all outgoing activities to prevent leaking
   private audiences.
 * Sync ActivityPub blog actor settings via Jetpack.
 * Use ap_actor post ID for remote account IDs instead of remapping URI strings.
 * Use safe HTTP request for signature retry to prevent requests to private IP ranges.
 * Validate emoji updated timestamps before storing them.

### 8.0.2 – 2026-03-17

#### Security

 * Prevent non-public posts (drafts, scheduled, pending review) from being accessible
   via ActivityPub.

### 8.0.1 – 2026-03-11

#### Changed

 * Simplify the follow page block pattern to avoid duplicate headings and improve
   accessibility.

#### Fixed

 * Fix dark sidebar colors appearing incorrectly with non-default admin color schemes.
 * Fix Fediverse Reactions block not aligning with post content in block themes.
 * Fix new posts being marked as modified on load, which prevented Gutenberg’s starter
   pattern modal from appearing.

### 8.0.0 – 2026-03-04

#### Security

 * Prevent private recipient lists from being shared when sending activities to 
   other servers.

#### Added

 * Add a help section to interaction dialogs explaining the Fediverse and why entering
   a profile is needed.
 * Add a notice on the Settings page to easily switch from legacy template mode 
   to automatic mode.
 * Add a pre-publish suggestion that recommends a post format for better compatibility
   with media-focused Fediverse platforms.
 * Add a Site Health check that warns when plugins are causing too many federation
   updates.
 * Add backwards compatibility for the `ACTIVITYPUB_DISABLE_SIDELOADING` constant
   and `activitypub_sideloading_enabled` filter from version 7.9.1.
 * Add bot account snippet that marks ActivityPub profiles as automated accounts,
   displaying a “BOT” badge on Mastodon and other Fediverse platforms.
 * Add Cache namespace for remote media caching with CLI commands, improved MIME
   validation, and filter-based architecture.

 * Fix reactions block layout on small screens and remove unwanted button highlight

   names in the Digest header.

   saved.
