/**
* Class ContentSecurityPolicy is a simple helper which allows applications to
* modify the Content-Security-Policy sent by Nextcloud. Per default only JavaScript,
* stylesheets, images, fonts, media and connections from the same domain
* ('self') are allowed.
*
* Even if a value gets modified above defaults will still get appended. Please
* notice that Nextcloud ships already with sensible defaults and those policies
* should require no modification at all for most use-cases.
*
* This class allows unsafe-eval of javascript and unsafe-inline of CSS.
*
* @package OCP\AppFramework\Http

* @deprecated 14.0.0 Use one of our stricter CSP policies

Add public API to give developers the possibility to adjust the global CSP defaults Allows to inject something into the default content policy. This is for example useful when you're injecting Javascript code into a view belonging to another controller and cannot modify its Content-Security-Policy itself. Note that the adjustment is only applied to applications that use AppFramework controllers. To use this from your `app.php` use `\OC::$server->getContentSecurityPolicyManager()->addDefaultPolicy($policy)`, $policy has to be of type `\OCP\AppFramework\Http\ContentSecurityPolicy`. To test this add something like the following into an `app.php` of any enabled app: ``` $manager = \OC::$server->getContentSecurityPolicyManager(); $policy = new \OCP\AppFramework\Http\ContentSecurityPolicy(false); $policy->addAllowedFrameDomain('asdf'); $policy->addAllowedScriptDomain('yolo.com'); $policy->allowInlineScript(false); $manager->addDefaultPolicy($policy); $policy = new \OCP\AppFramework\Http\ContentSecurityPolicy(false); $policy->addAllowedFontDomain('yolo.com'); $manager->addDefaultPolicy($policy); $policy = new \OCP\AppFramework\Http\ContentSecurityPolicy(false); $policy->addAllowedFrameDomain('banana.com'); $manager->addDefaultPolicy($policy); ``` If you now open the files app the policy should be: ``` Content-Security-Policy:default-src 'none';script-src yolo.com 'self' 'unsafe-eval';style-src 'self' 'unsafe-inline';img-src 'self' data: blob:;font-src yolo.com 'self';connect-src 'self';media-src 'self';frame-src asdf banana.com 'self' ```
