	Logs a content-security-policy violation report from web browser.

	getAllowedParams ()
	Returns an array of allowed parameters (parameter name) => (default value) or (parameter name) => (array with PARAM_* constants as keys) Don't call this function directly: use getFinalParams() to allow hooks to modify parameters as needed.

◆ getAllowedParams()

ApiCSPReport::getAllowedParams ( )

Returns an array of allowed parameters (parameter name) => (default value) or (parameter name) => (array with PARAM_* constants as keys) Don't call this function directly: use getFinalParams() to allow hooks to modify parameters as needed.

Some derived classes may choose to handle an integer $flags parameter in the overriding methods. Callers of this method can pass zero or more OR-ed flags like GET_VALUES_FOR_HELP.

Stable to override

Returns: array

◆ getFlags()

ApiCSPReport::getFlags	(		$report,
			$userAgent )

private

Get extra notes about the report.

Parameters

array	$report	The CSP report
string	$userAgent

Returns: array

◆ isInternal()

ApiCSPReport::isInternal ( )

Mark as internal.

Definition at line 292 of file ApiCSPReport.php.

◆ isWriteMode()

ApiCSPReport::isWriteMode ( )

Indicates whether this module requires write mode.

This should return true for modules that may require synchronous database writes. Modules that do not need such writes should also not rely on master database access, since only read queries are needed and each master DB is a single point of failure. Additionally, requests that only need replica DBs can be efficiently routed to any datacenter via the Promise-Non-Write-API-Action header.

Stable to override

Returns: bool

Reimplemented from ApiBase.

string	$url
string[]	$patterns

Doesn't touch db, so max lag should be rather irrelavent.

Also, this makes sure that reports aren't lost during lag events.

Returns: bool
