◆ 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.

Returns: array

◆ isInternal()

ApiCSPReport::isInternal ( )

Mark as internal.

Definition at line 290 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.

Returns: bool

Reimplemented from ApiBase.

Definition at line 274 of file ApiCSPReport.php.
