原文外掛簡介

BlackSwan Block External Request gives you granular control over every outgoing connection your WordPress site makes — both server-side PHP requests and browser-loaded JS/CSS resources.
WordPress, plugins, and themes constantly send background HTTP requests: update checks, license pings, analytics, font downloads, CDN calls, and more. On slow servers or restricted hosting environments, these requests can add seconds to every admin page load.
This plugin lets you block what you don’t need and keep what you do.
What it does
Server-side HTTP Blocking (PHP)
Intercepts outgoing wp_remote_get / wp_remote_post calls via the pre_http_request filter. Add domains to the blacklist and they’ll be blocked before the request is even made. Whitelist specific URL patterns to let essential requests through (e.g. plugin update API).
Browser-side Resource Blocking (JS/CSS by Domain)
Deregisters enqueued JavaScript and CSS files loaded from blacklisted external domains. Toggle separately for admin panel and public frontend. Your own site’s assets are never touched.
Block Specific Resources (by URL)
Block individual JS or CSS files by full URL, partial path, or even just a filename — works for both local and external resources. Per-item backend/frontend toggle. Perfect for removing unwanted plugin assets without editing code.
Features

Who is this for?

Sites on slow or restricted hosting where external calls cause timeouts
Developers debugging performance issues
Agencies managing client sites that don’t need update checks
Anyone who wants a faster wp-admin experience

Developer Hooks
Two filters are available for developers to customize blocking behavior programmatically. These run on every page load and merge with the values from the settings page.
BlackSwan\block_external_request\block_url_list
Filter the array of blocked domain strings. Each entry is matched via strpos() against the full request URL.
add_filter( 'BlackSwan\block_external_request\block_url_list', function( $domains ) {
$domains[] = 'analytics.example.com';
return $domains;
});

BlackSwan\block_external_request\whitelist_urls
Filter the array of whitelisted URL patterns. If a blocked URL also matches a whitelist pattern (via strpos()), the request is allowed through.
add_filter( 'BlackSwan\block_external_request\whitelist_urls', function( $patterns ) {
$patterns[] = '//api.example.com/v2/license';
return $patterns;
});

Whitelist patterns take priority over blacklist domains. Both filters accept and return a flat array of strings.
