    description: `如果订阅 [共和国追梦人](http://www.radio.cn/pc-portal/sanji/detail.html?columnId=1552135)，其 URL 为 \`https://www.radio.cn/pc-portal/sanji/detail.html?columnId=1552135\`，可以得到 \`columnId\` 为 \`1552135\`

  所以对应路由为 [\`/radio/1552135\`](https://rsshub.app/radio/1552135)

::: tip
  该路由仅适用于更新时间较早的电台节目，如 [共和国追梦人](http://www.radio.cn/pc-portal/sanji/detail.html?columnId=1552135)

  与适用于 [专辑](#yun-ting-zhuan-ji) 路由的专辑其 \`columnId\` 长度相比，它们的 \`columnId\` 长度较短
