パラメーターの履歴

  • v1.26: 以前の rnlimit の制限値 10/20 を標準の 500/5000 に増加しました。
  • v1.26: rnredirect を廃止予定にしました
  • v1.26: rnfilterredir を導入しました
  • v1.14: rnredirect を導入しました

追加的な注記

  • Unlike most modules in the Action API, the default number of pages returned is 1, not 10.
  • Pages are returned in a fixed sequence; only the starting point is actually random.
  • The default behavior is to pick pages from across the entire wiki, including talk pages, user pages, and so on. If you are looking for similar functionality as Special:Random, i.e. pick random articles, restrict rnnamespace to 0.
  • If the number of pages is fewer than rnlimit, the request will simply return all available pages. It will not repeat pages to pad out the response up to the limit.
