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.
- 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
rnnamespaceto0. - 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.
