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

Definition at line 37 of file ApiBase.php.

◆ addError()

ApiBase::addError	(	$msg,
		$code = `null`,
		$data = `null`
	)

Add an error for this module without aborting.

If $msg is not an ApiMessage, the message code will be derived from the message key by stripping any "apiwarn-" or "apierror-" prefix.

Note: If you want to abort processing, use self::dieWithError() instead.

Since: 1.29

Parameters

◆ addWarning()

ApiBase::addWarning	(	$msg,
		$code = `null`,

	)

Add a warning for this module.

Users should monitor this section to notice any changes in API. Multiple calls to this function will result in multiple warning messages.

If $msg is not an ApiMessage, the message code will be derived from the message key by stripping any "apiwarn-" or "apierror-" prefix.

Since: 1.29

Parameters

string \| array \| Message	$msg	See ApiErrorFormatter::addWarning()
string \| null	$code	See ApiErrorFormatter::addWarning()

◆ execute()

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().

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 | array

$options

If a boolean, uses that as the value for 'parseLimit'

parseLimit: (bool, default true) Whether to parse the 'max' value for limit types

◆ mustBePosted()

ApiBase::mustBePosted ( )

Indicates whether this module must be called with a POST request.

Returns: bool

Definition at line 454 of file ApiBase.php.

References needsToken().

Referenced by getHelpFlags().

◆ needsToken()

ApiBase::needsToken ( )

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.

Returns: string|false

Prior to 1.29, this was a public mapping from arbitrary strings (often message keys used elsewhere in MediaWiki) to API codes and message texts, and a few interfaces required poking something in here.

◆ PARAM_TEMPLATE_VARS

const ApiBase::PARAM_TEMPLATE_VARS = 25

(array) Indicate that this is a templated parameter, and specify replacements.

Keys are the placeholders in the parameter name and values are the names of (unprefixed) parameters from which the replacement values are taken.

For example, a parameter "foo-{ns}-{title}" could be defined with PARAM_TEMPLATE_VARS => [ 'ns' => 'namespaces', 'title' => 'titles' ]. Then a query for namespaces=0|1&titles=X|Y would support parameters foo-0-X, foo-0-Y, foo-1-X, and foo-1-Y.

All placeholders must be present in the parameter's name. Each target parameter must have PARAM_ISMULTI true. If a target is itself a templated parameter, its PARAM_TEMPLATE_VARS must be a subset of the referring parameter's, mapping the same placeholders to the same targets. A parameter cannot target itself.

◆ PARAM_TYPE

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. Forces PARAM_ALL = true to support easily specifying all namespaces.
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.
