All API modules are subclasses of, but some types of modules use a derived base class. The method of registration also depends on the module type.


 * action modules
 * Modules that provide a value for the main  parameter should subclass . They should be registered in   using the   key.


 * format modules
 * Modules that provide a value for the main  parameter should subclass . They should be registered in   using the   key. It's very uncommon for an extension to need to add a format module.


 * query submodules
 * Modules that provide a value for the,  , or   parameters to   should subclass  (if not usable as a generator) or  (if usable as a generator). They should be registered in   using the  ,  , or   key.

In all cases, the value for the registration key is an object with the module name (i.e. the value for the parameter) as the key and the class name as the value. Modules may also be registered conditionally using the (for action and format modules) and  (for query submodules) hooks.

بادئة
In the constructor of your API module, when you call you can specify an optional prefix for your module's parameters. (In the generated documentation for a module this prefix, if any, appears in parentheses in the heading for the module.) If your module is a query submodule then a prefix is required, since a client can invoke multiple submodules each with its own parameters in a single request. For action and format modules, the prefix is optional.

متغيرات
Most modules require parameters. These are defined by implementing. The return value is an associative array where keys are the (unprefixed) parameter names and values are either the scalar default value for the parameter or an array defining the properties of the parameter using the  constants defined by.

The example illustrates the syntax and some of the more common  constants.

Parameters are documented using MediaWiki's i18n mechanism. See #Documentation for details.



التنفيذ والناتج
The code actually implementing the module goes in the method. This code will generally use to get the input parameters, and will use  to get the  object to add any output to.

Query prop submodules should use to access the set of pages to operate on.

Query submodules that can be used as generators will also need to implement which is passed an  that should be filled with the generated pages. In this case, the  should generally not be used.

الحفظ المؤقت
By default API responses are marked as not cacheable ('Cache-Control: private')!

This still requires clients pass the  or   parameters to actually enable caching.

For query modules, do not call those methods. You can allow caching by instead implementing.

في كلتا الحالتين، تأكد من أن البيانات الخاصة غير معروضة.



التعامل مع الرموز
If your action module changes the wiki in any way, it should require a token of some kind. To have this handled automatically, implement the  method, returning the token that your module requires (probably the   edit token). The API base code will then automatically validate the token that clients provide in API requests in a  parameter.

If you don't want to use a token that is part of core, but rather a custom token with your own permission checks, use hook to register your token.



الوصول إلى قاعدة البيانات الرئيسية
If your module accesses the master database, it should implement the  method to return.



الأخطاء المردودة
includes several methods for performing various checks, for example,


 * If you need to assert that exactly one of a set of parameters was supplied, use.
 * If you need to assert that at most one of a set of parameters was supplied, use.
 * If you need to assert that at least one of a set of parameters was supplied, use.
 * If you need to assert that the user has certain rights, use.
 * If you need to assert that the user can take an action on a particular page, use.
 * If the user is blocked (and that matters to your module), pass the  object to.

But you will often run into cases where you need to raise an error of your own. The usual way to do that is to call, although if you have a  with the error information you could pass it to  instead.

If you need to issue a warning rather than an error, use or  if it's a deprecation warning.

التوثيق
The API is documented using MediaWiki's i18n mechanism. Needed messages generally have default names based on the module's "path". For action and format modules, the path is the same as the module's name used during registration. For query submodules, it's the name prefixed with "query+".

Every module will need a  message, which should be a one-line description of the module. If additional help text is needed,  may be created as well. Each parameter will need a  message, and parameters using   will also need a   for each value.

More details on API documentation are available at.

Extensions may also maintain extra API documentation on Wikimedia. This should be located on the extension's main page or, if more space is required, on pages named  or subpages thereof (e.g., , or ). The API namespace is reserved for the API of MediaWiki core.



توسيع الوحدات البرمجية في اللب البرمجي
Since MediaWiki 1.14, it's possible to extend core modules' functionality using the following hooks:


 * - to add or modify the module's parameter list
 * - to add or modify the module's parameter descriptions
 * - to do something after the module has been executed (but before the result has been output)
 * Use for ,   and   modules
 * If the module is run in generator mode, will be called instead

اختبار امتدادك
Your extension's help information should be correct.
 * Visit [/api.php api.php] and navigate to the generated help for your module or query submodule.
 * The example URLs you provided in  should appear under "Examples", try clicking them.
 * Omit and mangle URL parameters in the query string, check your extension's response.
 * Visit Special:ApiSandbox and interactively explore your API.
 * Visit to see additional information about your extension.
