Webmention Endpoint Discovery
Mostly a thought experiment to see what exactly is required to do Webmention endpoints discovery. You can use this implementation on its own, though it will probably net you better results to tightly integrate the code within the rest of your application.
Under the licence of this project you should feel free to copy any parts of it that you want to take for inspiration! Not even attribution is required – even when appreciated.
Install
Via Composer
Usage
$httpClientmust be an HTTP client implementingClientInterfaceas defined by PSR-18. Clients implementingHttpClientas defined by HTTPlug 1.x are also still accepted.$requestFactorymust be an implementation ofRequestFactoryInterfaceas defined by PHP-FIG as PSR-17.
Secure Endpoints
NOTE: This feature is very much experimental. Please consult the code before deciding to use it.
There might be some weird issues triggered by having Webmention senders post mentions to things on their local machines. The Webmention specification calls on senders to avoid sending Webmentions to localhost. This library enables that.
EndpointDiscovery::secureDiscover will return null not only when no
endpoint could be found, but also when the found endpoint’s host’s DNS
resolves to an IP address in the private or reserved range. When all the
IP addresses found are deemed to be OK, the method will return an array
as follows:
It is recommended that the Webmention sender uses this information for
posting the mention. Use one of the checked IP addresses to post to
(instead of the domain, which might redo the DNS lookup) with the host
in a Host HTTP header.
Supported PHP versions
This library requires PHP 7.0 or newer and is tested against PHP 7.0, 7.1, 7.2, 7.3, 7.4, 8.0, 8.1, 8.2, 8.3, 8.4 and 8.5.
Testing
Tests run on every supported PHP version through Docker, orchestrated by Castor. Each PHP version and its dependencies live entirely in their container, so only Docker and Castor are needed on the host:
The tests that make live calls to Webmention Rocks!
are marked with @group internet. Pass --offline to castor test or
