README

Generic permissions checker that centralizes all permission checks in one place.

Usage

Library provides Keboola\PermissionChecker\StorageApiTokenInterface interface that is expected to be implemented by caller (or provided by some other compatible library). The token is then passed to Keboola\PermissionChecker\PermissionChecker along with concrete checker for the action to be validated.

If the check passes, script execution continues normally. If the check fails, Keboola\PermissionChecker\Exception\PermissionException is thrown with a message that describes the reason of the failure and is safe to be presented to a user.

use Keboola\PermissionChecker\PermissionChecker;
use Keboola\PersmissionChecker\Checker\JobQueue\CanRunJob;

$storageToken = new MyStorageApiClass(...)

$checker = new PermissionChecker();
$checker->checkPermissions($storageToken, new CanRunJob(BranchType::DEFAULT, 'keboola.component-id'));

Development

Prerequisites:

• installed docker to run & develop the library

TL;DR:

docker compose run --rm dev-permission-checker composer install
docker compose run --rm dev-permission-checker composer ci

Implementing new checker

Each action that needs to be validated has its own checker - a class implementing Keboola\PermissionChecker\Checker\PermissionCheckerInterface. The interface has just a single method checkPermission which receives Keboola\PersmissionChecker\StorageApiToken instance (different class that the token passed to Keboola\PermissionChecker\PermissionChecker::checkPermissions()!) and throws Keboola\PermissionChecker\Exception\PermissionException if the check fails.

If the checker requires any additional data or depends on some other service, it is free to require it through its constructor.
