小编Kev*_* AB的帖子

我有以下路线。

http://localhost:4100/示例/5b8c94cfc5f85728db8bddf2/5bb426434722020c569fc5d8/(p1：.... // p2：.... // p3：...)

我有 3 条辅助路线，当我执行以下操作时遇到问题

this.router.navigate ([<any path>], {relativeTo: this.route})

，我在主出口航行，但次要出口 p1、p2、p3 未保留

有没有等于preserveQueryParams的东西？，navigationExtras？ https://angular.io/api/router/NavigationExtras 但对于辅助路线？

同一主题有几个问题,但我无法解决我的问题.
