重定向

在上面的示例中,仅会返回那些指向哲学页面的直接链接。 當 blredirect 被設定時,回傳結果將包含所有連結至 bltitle 所對應值之重定向頁面的頁面。

这些重定向的反向链接在响应层级中被视为独立的组,比重定向本身低一个层级。

bllimit 中設定的限制會分別套用至回應的每個層級,因此 bllimit=25 將返回最多25個直接反向連結,以及每個個別重定向內最多25個反向連結。

此外,當回應中包含重定向時,若使用blcontinue參數,系統會先返回更多第二級反向連結;待該重定向的所有反向連結均已完整返回後,才會轉而返回更多的直接反向連結。

可能的错误

代码 信息
blbadcontinue 无效继续参数。您应该传递由之前查询返回的原始值。
