推荐答案
事实上，MLSD 只不过是 RFC 3659 中引入的协议扩展，某些 FTP 服务器可能不支持.如果您关心可移植性，最好改用 f.nlst().
In the fact, MLSD is nothing but a protocol extension introduced in RFC 3659 that may be not supported by some FTP servers. If you care about portability, it's better to use f.nlst() instead.
如果您可以接受更改服务器上的某些内容，那么我建议您切换到 proftpd，它具有 MLSD 支持作为其 mod_facts 扩展的一部分.
If changing something on server is acceptable for you, then I suggest you switching to proftpd which has MLSD support as a part of it's mod_facts extension.
