  跳转到欲订阅的分类页，将 URL 的 \`/discover\` 到末尾的部分填入 \`params\` 参数。

  如 [全部原创视频作品](https://www.xinpianchang.com/discover/article-0-0-all-all-0-0-score) 的 URL 为 \`https://www.xinpianchang.com/discover/article-0-0-all-all-0-0-score\`，其 \`/discover\` 到末尾的部分为 \`article-0-0-all-all-0-0-score\`，所以对应的路由为 [/xinpianchang/discover/article-0-0-all-all-0-0-score](https://rsshub.app/xinpianchang/discover/article-0-0-all-all-0-0-score)。

    const limit = ctx.req.query('limit') ? Number.parseInt(ctx.req.query('limit'), 10) : 60;

    const currentUrl = new URL(`discover/${params}`, rootUrl).href;

    const { data, response } = await getData(currentUrl, cache.tryGet);
