路由地址（不包含参数）

NOTEXIST

完整路由地址，包含所有必选与可选参数

NOTEXIST

相关文档地址

https://docs.rsshub.app/parameter.html#tiao-shu-xian-zhi

为什么

  • 这个参数的实际作用是截取已有 item 的一部分，而无法提供更多 item，目前文档描述不清楚
  • 因其只对已获取到的 item 操作，所以当路由的 item 数量根据它来变动会存在缓存问题

Research direction
Investigate the current documentation for the 'limit' parameter at https://docs.rsshub.app/parameter.html and compare with the actual behavior in the RSSHub codebase. Look at the implementation of the limit parameter in route files and the caching logic to understand why caching causes the parameter to not increase the number of items. Propose clarification for the documentation and a fix for the caching issue.
