APIの説明文書


action=query

(main | query)

Fetch data from and about MediaWiki.

All data modifications will first have to use query to acquire a token to prevent abuse from malicious sites.

Parameters:
prop

Which properties to get for the queried pages.

categoryinfo
Returns information about the given categories.

クエリ モジュール群

クエリモジュールには3件のサブモジュールがあります (クエリモジュールとも呼ぶ)。

  • ウィキとログイン利用者に関するMeta 情報
  • 特定の基準に適合するページのリスト

例1: ページの指定

メタやリストクエリと比べると、プロパティクエリ モジュールは全て複数のページを処理でき、以下のいずれかの方法で対象ページを指定します。

  • ページ名を指定するにはtitlesパラメータを使う。例=titles=Foo|Bar|Main_Page
  • ページ ID の指定にはpageidsパラメータを使う。例=pageids=123|456|75915
  • 更新 ID の指定にはrevidsパラメータを使う。例=revids=478198|54872|54894545。 大部分のクエリモジュールでは更新 ID を対応するページ ID に変換します。 実際に更新 ID そのものを使うのは、prop=revisions のみです。

GET リクエスト

{
    "batchcomplete": true,
    "query": {
        "pages": [
            {
                "pageid": 1130,
                "ns": 0,
                "title": "Avicenna"
            },
            {
                "pageid": 17412,
                "ns": 0,
                "title": "Klein bottle"
            },

                "title": "Warrant"
            }
        ]
    }
}

例2: タイトルの平準化

タイトルの平準化により、ページ名を基準系に従って変換します。

簡単に言うと1文字目を大文字に、アンダーバー「 _ 」「半角スペースに、またそのウィキに適したページ名に地域化することです。

ページ名の末尾に改行マーク (\n) があると予想外の挙動の原因となるため、あらかじめ除去しておきます。

GET リクエスト

レスポンス

例3: ページ名がない、あるいは無効

存在しないもしくは無効なページ名は、missingまたはinvalid属性を付けて返してきます。

数字の並びキーをサポートする出力フォーマットでは、存在しないもしくは無効なページ名には、マイナスのページIDを与えます。

GET リクエスト

レスポンス

例4: 継続型のクエリ

もしクエリに対して返した分以外にもデータがある場合にはcontinue属性が付いており、追加のデータがあると示します。

残りのデータを取得するには、元のリクエストにその値を追加します。

GET リクエスト

レスポンス

例5: Batchcomplete

API はbatchcomplete 要素を返し、現在の項目群に対するデータは全て返したと示します。 MW 1.25+

以下のクエリに対してbatchcompleteをくわえてあるのは、画像3点全てにデータを返したと示しています。

次の継続クエリは、次の画像3点を対象にデータを返します。

GET リクエスト

レスポンス

例6: ジェネレータ

複数ページからデータを得るには、ジェネレータを使います。

例えば特定のカテゴリ内の複数ページからデータを得るには、クエリlist=categorymembersを実行してからその結果のページにもう一度、クエリpageidsをかけるのではなく、generator=categorymembersを使い2件のAPIを組み合わせます。

一覧モジュールをジェネレータとして使う場合は、対象ページの指定は不要です。

ただし属性のモジュールには ジェネレーターの作業対象の ページを指定する必要があります。

例えばメインページのリンク先のページを読み込むには、generator=links&titles=Main%20Pageを使用します。

Parameters passed to a generator must be prefixed with a g. For instance, when using generator=backlinks, use gbllimit instead of bllimit.

The sample query below gets links and categories for the first three pages in the main namespace starting with "Ba".

起こりうる警告

警告メッセージ 原因
No support for special pages has been implemented. Thrown if a title in the Special: or Media: namespace is given. The pages in these namespaces cannot be queried.
Redirect resolution cannot be used together with the revids parameter. Any redirects the revids point to have not been resolved. Thrown if the redirect parameter is used in a query that specifies pages using revids.

パラメーターの履歴

  • v1.21: continue を導入しました
  • v1.24: rawcontinue を導入しました (note raw continuation was the default behavior until v1.26)

追加的な注記

  • Specifying titles through titles or pageids is limited to 50 titles per query, or 500 for those with the apihighlimits right.
  • * 単一のリクエストで期待する結果を得るには、例えばprop=info|revisions&list=backlinks|embeddedin|allimages&meta=userinfoのように、複数のクエリを組み合わせます。
  • Generators only pass page titles to the query module and do not output any information themselves. Setting parameters like gcmprop will therefore have no effect.
