API:Calling internally/ja

The API can be called internally from within PHP without going through an HTTP request.

However, application logic should avoid this, and directly access the PHP classes that are responsible for the respective functionality, instead of going through the API framework.

Internal API calls should generally only be used for testing purposes, and quick prototyping.

From test suite code
To call the API from within tests, the easiest way is to extend your test class from  (rather than  ). Then you can use  as follows.

This is how tests of the API should be done, but sometimes you want a test to use the API in order to set up for other tests that are not actual API tests. In this case you'll probably not want to inherit from ApiTestCase.

In this situation the request has to be constructed in more detail because the edit token needs to be stored in the session. In this case, the  global is a FauxRequest that is already configured by the test harness.

From application code
ときに別の部分のコードでデータアクセスとAPIの集約機能を使いたいと思うことがあります. Rather than making an HTTP network request to the same server, you can make a call within PHP.

The steps are:

1) If you are executing in the context of an existing request from a user, prepare request parameters using the  class. Its constructor's third parameter is optional, specify   to treat the API call as a POST when the API module you're invoking requires POST requests.
 * Its constructor's first parameter is the request to derive from.
 * Its constructor's second parameter is an array of API parameters that is the same as if making the request over the web.

This sample code issues the 'allpages' list query starting at the letter 'M'. This is a simple query, not requiring a user or POST.

If you need to provide an edit token as an API parameter when making edits or other changes, you can get the edit token like so:

2) 2) ApiMainインスタンスを作り実行します. パラメータはFauxRequestオブジェクトのインスタンスなので、ApiMainはフォーマッティングのprintersを実行するのでもエラーを取り扱うのでもありません. パラメータエラーもしくは別の内部エラーはコードを呼び出す際にキャッチされる例外を引き起こします.

Important: If you want to create or edit pages, you have to pass  as a second parameter when creating the  :

3) 結果のデータ配列を取得します.

Here is a complete example taken from (as of ). It adds text to a page, so it must run when handling a logged-in user's HTTP request.

FauxRequest
The example above creates a. This "inherits" some of the original request, such as IP and request headers that are set when MediaWiki is doing an action on behalf of a user, typically when handling a web request. If there is no user request context, for example when invoking the action API from a system process, or if you want to make a completely separate internal request, then you can use  instead.

Using  for write operations without passing request context causes bug T36838.
