friendica/src/Module/Diaspora/Fetch.php
Philipp 8bdd90066f
Make BaseModule a real entity
- Add all dependencies, necessary to run the content (baseUrl, Arguments)
- Encapsulate all POST/GET/DELETE/PATCH/PUT methods as protected methods inside the BaseModule
- Return Module content ONLY per `BaseModule::run()` (including the Hook logic there as well)
