API:Login/ja

MediaWiki のウェブ サービスを使用する際、あなたのアプリケーションまたはクライアントをログインさせる必要がある場合があるでしょう. ログインには、ログイン クエリを送信する、Cookie を構築する、返された確認トークンを付加したログイン リクエストを再送信することでログインを確認する、という処理が必要になります.

ログインすべきかどうか
あなたのクライアントを MediaWiki にログインさせる必要があるのは以下の場合でしょう:


 * 特定の権限を持つ利用者に制限された情報を取得したり、制限された操作を実行する必要がある
 * 膨大なリクエストを発行するため、リクエストごとの制限を緩和したアカウント以外での実行が現実的ではない場合

On wikis that allow anonymous editing, it's possible to edit through the API without logging in, but it's highly recommended that you do log in. On private wikis, logging in is required to use any API functionality.

If your client is written in JavaScript, it'll usually act with the credentials of the user who's running it. In this case, you won't need to login using the web service API--you'll just need to ensure that the user has logged in through the web interface.

アプリケーション固有の利用者アカウント
Rather than having your application log in as yourself, you may want to create a separate user account just for your application. This is especially important if your application:


 * is carrying out automated editing or some other bulk operation.
 * invokes large or performance-intensive queries.

With a separate account, the changes made by your application can be easily tracked, and special rights (usually a "bot" user group) can be applied to the application's account. Some wikis have a policy related to automated editing, and/or a procedure for dealing with "bot" user group requests.

Login gets several tokens that are needed by the server to recognize the logged-in user. In every call to api.php, the cookie set by this request must be passed. The cookies last for around a month and you should check that you need to log in based on detecting that you're not logged in (rather than logging once per session, for example). You can check this on any request using the  generic parameter.

ログイン方法
Logging in through the API requires submitting a login query and constructing a cookie (many frameworks will construct the cookie automatically). In MediaWiki 1.15.3+, you must confirm the login by resubmitting the login request with the token returned.

ログイン リクエストの構造
The body of the POST can be empty. This request will also return a session cookie in the HTTP header that you have to return for the second request if your framework does not do this automatically. The sessionid parameter was added in MediaWiki 1.17 and later.

You might need to add the query parameter, containing your domain name for authentication, if you're using an authentication plug-in like Extension:LDAP Authentication.

Confirm token
If the response to the above query was  instead of , you can skip this step. (This extra step was added in MediaWiki 1.15.3.) In MediaWiki 1.15.4, first phase of login in ApiLogin.php is broken, so login/sessionid parameter is not returned, thus token confirmation is impossible. Apply ApiLogin.php file from MediaWiki 1.15.5 to your installation as a quick workaround while you plan your upgrade to 1.15.5. ApiLogin.php from MediaWiki 1.16+ is incompatible with MediaWiki 1.15.3+.

Cookie の処理
A successful  request will set cookies needed to be considered logged in. Many frameworks will handle these cookies automatically (such as the cookiejar in cURL). If so, by all means take advantage of this. If not, the most reliable method is to parse them from the HTTP response's Set-Cookie headers.

If this is not possible either, it is possible to construct the appropriate cookies from the various values returned by the  call, but this is not recommended as the necessary cookies may be changed without warning (e.g. something as simple as changing  would require changes to your manual cookie creation code).

When CentralAuth is enabled, as on Wikimedia wikis, the example above will not only log you in to a single domain, but also provide you with three centralauth cookies in the Set-Cookie response headers. To use these, duplicate those cookies (i.e. cookies whose names are prefixed with "centralauth_") and set the domain field of the new cookies to the new domain you'd like to log in at. Once this is done, any GET/POST request to this new domain will (assuming that the user has a SUL/global account) be answered with a reply containing Set-Cookie headers/Cookies specific to that domain.

エラー
Errors are returned in the result field. Possible values include:

速度制限
セキュリティ上の理由で、このモジュールには速度制限があります. By default, you get to login 5 times in 300 seconds, but this may vary from one wiki to another. When you exceed this limit, your login will fail (even if it's otherwise correct) with  and the number of seconds you need to wait in the   field.

 * Example login codes in PHP:
 * Example login (requires Snoopy)
 * Exemple login and navigate (using only file_get_contents)
 * Example login (using cURL) - no Snoopy required
 * Example login code in JS (using JQuery)
 * Example login code in Python
