参数历史

  • v1.26: 之前在rnlimit上的10/20的限制已提高到標準的500/5000的限制。
  • v1.26: 棄用rnredirect。
  • v1.26: 啟用rnfilterredir。
  • v1.14: 啟用rnredirect。

附加提醒

  • 不像許多模塊一樣在 Action API中,頁面的預設值是1而非10.
  • 頁面是以固定順序回傳；只有起始點是隨機的。
  • 預設行為是從整個維基中選取頁面，包括討論頁、使用者頁等等。 如果您想要的功能與Special:Random類似，即隨機選擇條目，請將rnnamespace限制到0。
  • 如果頁數少於rnlimit，則請求將直接傳回所有可用頁數。 它不會重複頁面以填充回應時間直至達到限制。
