Detailed Description

This abstract class implements many basic API functions, and is the base of all API classes.

The class functions are divided into several areas of functionality:

Module parameters: Derived classes can define getAllowedParams() to specify which parameters to expect, how to parse and validate them.

Self-documentation: code to allow the API to document its own state

			$moduleName,
			$modulePrefix = `''`

static ApiBase::escapeWikiText ( $v )

staticprivate

A subset of wfEscapeWikiText for BC texts.

Since: 1.25

Parameters

string | array $v

Returns: string|array

Definition at line 1487 of file ApiBase.php.

ApiBase::execute ( )

abstract

Evaluates the parameters, performs the requested query, and sets up the result.

Concrete implementations of ApiBase must override this method to provide whatever functionality their module offers. Implementations must not produce any output on their own and are not expected to handle any errors.

The execute() method will be invoked directly by ApiMain immediately before the result of the module is output. Aside from the constructor, implementations should assume that no other methods will be called externally on the module before the result is processed.

The result data should be stored in the ApiResult object available through getResult().

ApiBase::explodeMultiValue	(	$value,
		$limit
	)

protected

Split a multi-valued parameter string, like explode()

Since: 1.28

Parameters

string	$value
int	$limit

Returns: string[]

Definition at line 1196 of file ApiBase.php.

References $limit, and $value.

Referenced by ApiPageSet\handleParamNormalization(), and parseMultiValue().

ApiBase::extractRequestParams ( $parseLimit = true )

Using getAllowedParams(), this function makes an array of the values provided by the user, with key being the name of the variable, and value - validated value from user or default.

limits will not be parsed if $parseLimit is set to false; use this when the max limit is not definitive yet, e.g. when getting revisions.

Parameters

bool $parseLimit True by default

Returns: array

Definition at line 678 of file ApiBase.php.

References $params, as, getFinalParams(), and getParameterFromSettings().

ApiBase::getAllowedParams ( )

protected

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

Definition at line 338 of file ApiBase.php.

Referenced by getFinalParams().

ApiBase::getConditionalRequestData ( $condition )

Returns data for HTTP conditional request mechanisms.

Since: 1.26

Parameters

string

$condition

Condition being queried:

last-modified: Return a timestamp representing the maximum of the last-modified dates for all resources involved in the request. See RFC 7232 § 2.2 for semantics.
etag: Return an entity-tag representing the state of all resources involved in the request. Quotes must be included. See RFC 7232 § 2.3 for semantics.

Returns: string|bool|null As described above, or null if no value is available.

ApiBase::getContinuationManager ( )

Get the continuation manager.

Returns: ApiContinuationManager|null

ApiBase::getCustomPrinter ( )

If the module may only be used with a certain format module, it should override this method to return an instance of that formatter.

A value of null means the default format will be used.

Note: Do not use this just because you don't want to support non-json formats. This should be used only when there is a fundamental requirement for a specific format.

Returns: mixed Instance of a derived class of ApiFormatBase, or null

numeric keys with partial URLs ("api.php?" plus a query string) as values
sequential numeric keys with even-numbered keys being display-text and odd-numbered keys being partial urls
partial URLs as keys with display-text (string or array-to-be-joined) as values Return value as a string is the same as an array with a numeric key and that value, and boolean false means "no examples".

Returns the token type this module requires in order to execute.

Modules are strongly encouraged to use the core 'csrf' type unless they have specialized security needs. If the token type is not one of the core types, you must use the ApiQueryTokensRegisterTypes hook to register it.

Returning a non-falsey value here will force the addition of an appropriate 'token' parameter in self::getFinalParams(). Also, self::mustBePosted() must return true when tokens are used.

In previous versions of MediaWiki, true was a valid return value. Returning true will generate errors indicating that the API module needs updating.

const ApiBase::PARAM_TYPE = 2

(string|string[]) Either an array of allowed value strings, or a string type as described below.

If not specified, will be determined from the type of PARAM_DFLT.

Supported string types are:

boolean: A boolean parameter, returned as false if the parameter is omitted and true if present (even with a falsey value, i.e. it works like HTML checkboxes). PARAM_DFLT must be boolean false, if specified. Cannot be used with PARAM_ISMULTI.
integer: An integer value. See also PARAM_MIN, PARAM_MAX, and PARAM_RANGE_ENFORCE.
limit: An integer or the string 'max'. Default lower limit is 0 (but see PARAM_MIN), and requires that PARAM_MAX and PARAM_MAX2 be specified. Cannot be used with PARAM_ISMULTI.
namespace: An integer representing a MediaWiki namespace.
NULL: Any string.
password: Any non-empty string. Input value is private or sensitive. <input type="password"> would be an appropriate HTML form field.
string: Any non-empty string, not expected to be very long or contain newlines. <input type="text"> would be an appropriate HTML form field.
submodule: The name of a submodule of this module, see PARAM_SUBMODULE_MAP.
tags: A string naming an existing, explicitly-defined tag. Should usually be used with PARAM_ISMULTI.
text: Any non-empty string, expected to be very long or contain newlines. <textarea> would be an appropriate HTML form field.
timestamp: A timestamp in any format recognized by MWTimestamp, or the string 'now' representing the current timestamp. Will be returned in TS_MW format.
user: A MediaWiki username or IP. Will be returned normalized but not canonicalized.
upload: An uploaded file. Will be returned as a WebRequestUpload object. Cannot be used with PARAM_ISMULTI.
