  对于 [事件追蹤](https://news.now.com/home/tracker) 中的 [塔利班奪權](https://news.now.com/home/tracker/detail?catCode=123\&topicId=1056) 话题，其网址为 \`https://news.now.com/home/tracker/detail?catCode=123&topicId=1056\`，其中 \`topicId\` 为 1056，则对应路由为 [\`/now/news/tracker/1056\`](https://rsshub.app/now/news/tracker/1056)
