◆ 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

Returns: array

◆ isInternal()

ApiCSPReport::isInternal ( )

Mark as internal.

ApiCSPReport::isReadMode ( )

Even if you don't have read rights, we still want your report.

Returns: bool

Reimplemented from ApiBase.

Definition at line 240 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 224 of file ApiCSPReport.php.

◆ logReport()

Returns: bool

Reimplemented from ApiBase.

Definition at line 220 of file ApiCSPReport.php.

◆ shouldCheckMaxLag()

ApiCSPReport::shouldCheckMaxLag ( )

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

◆ verifyPostBodyOk()

ApiCSPReport::verifyPostBodyOk ( )

private

Output an api error if post body is obviously not OK.
